SDK for PHP 3.x

Client: Aws\Ecs\EcsClient
Service ID: ecs
Version: 2014-11-13

This page describes the parameters and results for the operations of the Amazon EC2 Container Service (2014-11-13), and shows how to use the Aws\Ecs\EcsClient object to call the described operations. This documentation is specific to the 2014-11-13 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Operations

CreateCapacityProvider

$result = $client->createCapacityProvider([/* ... */]);
$promise = $client->createCapacityProviderAsync([/* ... */]);

Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.

Only capacity providers that use an Auto Scaling group can be created. Amazon ECS tasks on Fargate use the FARGATE and FARGATE_SPOT capacity providers. These providers are available to all accounts in the Amazon Web Services Regions that Fargate supports.

Parameter Syntax

$result = $client->createCapacityProvider([
    'autoScalingGroupProvider' => [ // REQUIRED
        'autoScalingGroupArn' => '<string>', // REQUIRED
        'managedDraining' => 'ENABLED|DISABLED',
        'managedScaling' => [
            'instanceWarmupPeriod' => <integer>,
            'maximumScalingStepSize' => <integer>,
            'minimumScalingStepSize' => <integer>,
            'status' => 'ENABLED|DISABLED',
            'targetCapacity' => <integer>,

            'value' => '<string>',
        ],
        // ...
    ],
]);

Parameter Details

Members
autoScalingGroupProvider
Required: Yes
Type: AutoScalingGroupProvider structure

The details of the Auto Scaling group for the capacity provider.

name
Required: Yes
Type: string

The name of the capacity provider. Up to 255 characters are allowed. They include letters (both upper and lowercase letters), numbers, underscores (_), and hyphens (-). The name can't be prefixed with "aws", "ecs", or "fargate".

tags
Type: Array of Tag structures

The metadata that you apply to the capacity provider to categorize and organize them more conveniently. Each tag consists of a key and an optional value. You define both of them.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

LimitExceededException:

The limit for the resource was exceeded.

UpdateInProgressException:

There's already a current Amazon ECS container agent update in progress on the container instance that's specified. If the container agent becomes disconnected while it's in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.

CreateCluster

$result = $client->createCluster([/* ... */]);
$promise = $client->createClusterAsync([/* ... */]);

Creates a new Amazon ECS cluster. By default, your account receives a default cluster when you launch your first container instance. However, you can create your own cluster with a unique name with the CreateCluster action.

When you call the CreateCluster API operation, Amazon ECS attempts to create the Amazon ECS service-linked role for your account. This is so that it can manage required resources in other Amazon Web Services services on your behalf. However, if the user that makes the call doesn't have permissions to create the service-linked role, it isn't created. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

Parameter Details

Members
capacityProviders
Type: Array of strings

The short name of one or more capacity providers to associate with the cluster. A capacity provider must be associated with a cluster before it can be included as part of the default capacity provider strategy of the cluster or used in a capacity provider strategy when calling the CreateService or RunTask actions.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must be created but not associated with another cluster. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

The PutCapacityProvider API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

clusterName
Type: string

The name of your cluster. If you don't specify a name for your cluster, you create a cluster that's named default. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

configuration
Type: ClusterConfiguration structure

The execute command configuration for the cluster.

defaultCapacityProviderStrategy
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to set as the default for the cluster. After a default capacity provider strategy is set for a cluster, when you call the CreateService or RunTask APIs with no capacity provider strategy or launch type specified, the default capacity provider strategy for the cluster is used.

If a default capacity provider strategy isn't defined for a cluster when it was created, it can be defined later with the PutClusterCapacityProviders API operation.

serviceConnectDefaults

Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

settings
Type: Array of ClusterSetting structures

The setting to use when creating a cluster. This parameter is used to turn on CloudWatch Container Insights for a cluster. If this value is specified, it overrides the containerInsights value set with PutAccountSetting or PutAccountSettingDefault.

tags
Type: Array of Tag structures

The metadata that you apply to the cluster to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

CreateService

$result = $client->createService([/* ... */]);
$promise = $client->createServiceAsync([/* ... */]);

Runs and maintains your desired number of tasks from a specified task definition. If the number of tasks running in a service drops below the desiredCount, Amazon ECS runs another copy of the task in the specified cluster. To update an existing service, see the UpdateService action.

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. volumeConfigurations is only supported for REPLICA service and not DAEMON service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

Tasks for services that don't use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.

There are two service scheduler strategies available:

  • REPLICA - The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.

  • DAEMON - The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide.

You can optionally specify a deployment configuration for your service. The deployment is initiated by changing properties. For example, the deployment might be initiated by the task definition or by your desired count of a service. This is done with an UpdateService operation. The default value for a replica service for minimumHealthyPercent is 100%. The default value for a daemon service for minimumHealthyPercent is 0%.

If a service uses the ECS deployment controller, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment. Specifically, it represents it as a percentage of your desired number of tasks (rounded up to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can deploy without using additional cluster capacity. For example, if you set your service to have desired number of four tasks and a minimum healthy percent of 50%, the scheduler might stop two existing tasks to free up cluster capacity before starting two new tasks. If they're in the RUNNING state, tasks for services that don't use a load balancer are considered healthy . If they're in the RUNNING state and reported as healthy by the load balancer, tasks for services that do use a load balancer are considered healthy . The default value for minimum healthy percent is 100%.

If a service uses the ECS deployment controller, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment. Specifically, it represents it as a percentage of the desired number of tasks (rounded down to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.

If a service uses either the CODE_DEPLOY or EXTERNAL deployment controller types and tasks that use the EC2 launch type, the minimum healthy percent and maximum percent values are used only to define the lower and upper limit on the number of the tasks in the service that remain in the RUNNING state. This is while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent and maximum percent values aren't used. This is the case even if they're currently visible when describing your service.

When creating a service that uses the EXTERNAL deployment controller, you can specify only parameters that aren't controlled at the task set level. The only required parameter is the service name. You control your services using the CreateTaskSet operation. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

When the service scheduler launches new tasks, it determines task placement. For information about task placement and task placement strategies, see Amazon ECS task placement in the Amazon Elastic Container Service Developer Guide

Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

Parameter Details

Members
capacityProviderStrategy
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to use for the service.

If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

A capacity provider strategy may contain a maximum of 6 capacity providers.

clientToken
Type: string

An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.

cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that you run your service on. If you do not specify a cluster, the default cluster is assumed.

deploymentConfiguration
Type: DeploymentConfiguration structure

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

deploymentController
Type: DeploymentController structure

The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.

desiredCount
Type: int

The number of instantiations of the specified task definition to place and keep running in your service.

This is required if schedulingStrategy is REPLICA or isn't specified. If schedulingStrategy is DAEMON then this isn't required.

enableECSManagedTags
Type: boolean

Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide.

When you use Amazon ECS managed tags, you need to set the propagateTags request parameter.

enableExecuteCommand
Type: boolean

Determines whether the execute command functionality is turned on for the service. If true, this enables execute command functionality on all containers in the service tasks.

healthCheckGracePeriodSeconds
Type: int

The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of 0 is used.

If you do not use an Elastic Load Balancing, we recommend that you use the startPeriod in the task definition health check parameters. For more information, see Health check.

If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds (about 69 years). During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.

launchType
Type: string

The infrastructure that you run your service on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.

Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide.

The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.

The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.

A service can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

loadBalancers
Type: Array of LoadBalancer structures

A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

If the service uses the rolling update (ECS) deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

If the service uses the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair). During a deployment, CodeDeploy determines which task set in your service has the status PRIMARY, and it associates one target group with it. Then, it also associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that you can use to perform validation tests with Lambda functions before routing production traffic to it.

If you use the CODE_DEPLOY deployment controller, these values can be changed when updating the service.

For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name, and the container port to access from the load balancer. The container name must be as it appears in a container definition. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group that's specified here.

For Classic Load Balancers, this object must contain the load balancer name, the container name , and the container port to access from the load balancer. The container name must be as it appears in a container definition. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer that's specified here.

Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers aren't supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance. This is because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.

networkConfiguration
Type: NetworkConfiguration structure

The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide.

placementConstraints
Type: Array of PlacementConstraint structures

An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.

placementStrategy
Type: Array of PlacementStrategy structures

The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules for each service.

platformVersion
Type: string

The platform version that your tasks in the service are running on. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

propagateTags
Type: string

Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.

You must set this to a value other than NONE when you use Cost Explorer. For more information, see Amazon ECS usage reports in the Amazon Elastic Container Service Developer Guide.

The default is NONE.

role
Type: string

The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is only permitted if you are using a load balancer with your service and your task definition doesn't use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.

If your account has already created the Amazon ECS service-linked role, that role is used for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you don't specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

If your specified role has a path other than /, then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide.

schedulingStrategy
Type: string

The scheduling strategy to use for the service. For more information, see Services.

There are two service scheduler strategies available:

  • REPLICA-The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.

  • DAEMON-The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

    Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.

serviceConnectConfiguration
Type: ServiceConnectConfiguration structure

The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

serviceName
Required: Yes
Type: string

The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.

serviceRegistries
Type: Array of ServiceRegistry structures

The details of the service discovery registry to associate with this service. For more information, see Service discovery.

Each service may be associated with one service registry. Multiple service registries for each service isn't supported.

tags
Type: Array of Tag structures

The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskDefinition
Type: string

The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision isn't specified, the latest ACTIVE revision is used.

A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.

For more information about deployment types, see Amazon ECS deployment types.

volumeConfigurations
Type: Array of ServiceVolumeConfiguration structures

The configuration for a volume specified in the task definition as a volume that is configured at launch time. Currently, the only supported volume type is an Amazon EBS volume.

Result Details

Members
service
Type: Service structure

The full description of your service following the create call.

A service will return either a capacityProviderStrategy or launchType parameter, but not both, depending where one was specified when it was created.

If a service is using the ECS deployment controller, the deploymentController and taskSets parameters will not be returned.

if the service uses the CODE_DEPLOY deployment controller, the deploymentController, taskSets and deployments parameters will be returned, however the deployments parameter will be an empty list.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

UnsupportedFeatureException:

The specified task isn't supported in this Region.

PlatformUnknownException:

The specified platform version doesn't exist.

PlatformTaskDefinitionIncompatibilityException:

The specified platform version doesn't satisfy the required capabilities of the task definition.

AccessDeniedException:

You don't have authorization to perform the requested action.

NamespaceNotFoundException:

The specified namespace wasn't found.

Examples

Example 1: To create a new service

This example creates a service in your default region called ``ecs-simple-service``. The service uses the ``hello_world`` task definition and it maintains 10 copies of that task.

$result = $client->createService([
    'desiredCount' => 10,
    'serviceName' => 'ecs-simple-service',
    'taskDefinition' => 'hello_world',
]);

Example 2: To create a new service behind a load balancer

This example creates a service in your default region called ``ecs-simple-service-elb``. The service uses the ``ecs-demo`` task definition and it maintains 10 copies of that task. You must reference an existing load balancer in the same region by its name.

$result = $client->createService([
    'desiredCount' => 10,
    'loadBalancers' => [
        [

CreateTaskSet

$result = $client->createTaskSet([/* ... */]);
$promise = $client->createTaskSetAsync([/* ... */]);

Create a task set in the specified cluster and service. This is used when a service uses the EXTERNAL deployment controller type. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

For information about the maximum number of task sets and otther quotas, see Amazon ECS service quotas in the Amazon Elastic Container Service Developer Guide.

Parameter Details

Members
capacityProviderStrategy
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to use for the task set.

A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.

If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

clientToken
Type: string

An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.

cluster
Required: Yes
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to create the task set in.

externalId
Type: string

An optional non-unique tag that identifies this task set in external systems. If the task set is associated with a service discovery registry, the tasks in this task set will have the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute set to the provided value.

launchType
Type: string

The launch type that new tasks in the task set uses. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

loadBalancers
Type: Array of LoadBalancer structures

A load balancer object representing the load balancer to use with the task set. The supported load balancer types are either an Application Load Balancer or a Network Load Balancer.

networkConfiguration
Type: NetworkConfiguration structure

An object representing the network configuration for a task set.

platformVersion
Type: string

The platform version that the tasks in the task set uses. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used.

scale
Type: Scale structure

A floating-point percentage of the desired number of tasks to place and keep running in the task set.

service
Required: Yes
Type: string

The short name or full Amazon Resource Name (ARN) of the service to create the task set in.

serviceRegistries
Type: Array of ServiceRegistry structures

The details of the service discovery registries to assign to this task set. For more information, see Service discovery.

tags
Type: Array of Tag structures

The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both. When a service is deleted, the tags are deleted.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskDefinition
Required: Yes
Type: string

The task definition for the tasks in the task set to use. If a revision isn't specified, the latest ACTIVE revision is used.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

ClusterContainsContainerInstancesException:

You can't delete a cluster that has registered container instances. First, deregister the container instances before you can delete the cluster. For more information, see DeregisterContainerInstance.

ClusterContainsServicesException:

You can't delete a cluster that contains services. First, update the service to reduce its desired task count to 0, and then delete the service. For more information, see UpdateService and DeleteService.

ClusterContainsTasksException:

You can't delete a cluster that has active tasks.

UpdateInProgressException:

There's already a current Amazon ECS container agent update in progress on the container instance that's specified. If the container agent becomes disconnected while it's in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.

Examples

DeleteService

$result = $client->deleteService([/* ... */]);
$promise = $client->deleteServiceAsync([/* ... */]);

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.

When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING, and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE. Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.

If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

Result Details

Members
service
Type: Service structure

The full description of the deleted service.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

ServiceNotFoundException:

The specified service wasn't found. You can view your available services with ListServices. Amazon ECS services are cluster specific and Region specific.

Examples

Example 1: To delete a service

This example deletes the my-http-service service. The service must have a desired count and running count of 0 before you can delete it.

$result = $client->deleteService([
    'service' => 'my-http-service',
]);

Result syntax:

[
]

DeleteTaskDefinitions

$result = $client->deleteTaskDefinitions([/* ... */]);
$promise = $client->deleteTaskDefinitionsAsync([/* ... */]);

Deletes one or more task definitions.

You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.

When you delete a task definition revision, it is immediately transitions from the INACTIVE to DELETE_IN_PROGRESS. Existing tasks and services that reference a DELETE_IN_PROGRESS task definition revision continue to run without disruption. Existing services that reference a DELETE_IN_PROGRESS task definition revision can still scale up or down by modifying the service's desired count.

You can't use a DELETE_IN_PROGRESS task definition revision to run new tasks or create new services. You also can't update an existing service to reference a DELETE_IN_PROGRESS task definition revision.

A task definition revision will stay in DELETE_IN_PROGRESS status until all the associated tasks and services have been terminated.

When you delete all INACTIVE task definition revisions, the task definition name is not displayed in the console and not returned in the API. If a task definition revisions are in the DELETE_IN_PROGRESS state, the task definition name is displayed in the console and returned in the API. The task definition name is retained by Amazon ECS and the revision is incremented the next time you create a task definition with that name.

Parameter Syntax

$result = $client->deleteTaskDefinitions([
    'taskDefinitions' => ['<string>', ...], // REQUIRED
]);

Parameter Details

Members
taskDefinitions
Required: Yes
Type: Array of strings

The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to delete. You must specify a revision.

You can specify up to 10 task definitions as a comma separated list.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

UnsupportedFeatureException:

The specified task isn't supported in this Region.

AccessDeniedException:

You don't have authorization to perform the requested action.

ServiceNotFoundException:

The specified service wasn't found. You can view your available services with ListServices. Amazon ECS services are cluster specific and Region specific.

ServiceNotActiveException:

The specified service isn't active. You can't update a service that's inactive. If you have previously deleted a service, you can re-create it with CreateService.

TaskSetNotFoundException:

The specified task set wasn't found. You can view your available task sets with DescribeTaskSets. Task sets are specific to each cluster, service and Region.

DeregisterContainerInstance

$result = $client->deregisterContainerInstance([/* ... */]);
$promise = $client->deregisterContainerInstanceAsync([/* ... */]);

Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.

If you intend to use the container instance for some other purpose after deregistration, we recommend that you stop all of the tasks running on the container instance before deregistration. That prevents any orphaned tasks from consuming resources.

Deregistering a container instance removes the instance from a cluster, but it doesn't terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.

If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents aren't automatically deregistered when terminated).

Parameter Syntax

$result = $client->deregisterContainerInstance([
    'cluster' => '<string>',
    'containerInstance' => '<string>', // REQUIRED
    'force' => true || false,
]);

Parameter Details

Members
cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.

containerInstance
Required: Yes
Type: string

The container instance ID or full ARN of the container instance to deregister. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide.

force
Type: boolean

Forces the container instance to be deregistered. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they're orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.

Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered. They begin connection draining according to the settings on the load balancer or target group.

Examples

Example 1: To deregister a container instance from a cluster

This example deregisters a container instance from the specified cluster in your default region. If there are still tasks running on the container instance, you must either stop those tasks before deregistering, or use the force option.

$result = $client->deregisterContainerInstance([
    'cluster' => 'default',
    'containerInstance' => 'container_instance_UUID',
    'force' => 1,
]);

DeregisterTaskDefinition

$result = $client->deregisterTaskDefinition([/* ... */]);
$promise = $client->deregisterTaskDefinitionAsync([/* ... */]);

Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as INACTIVE. Existing tasks and services that reference an INACTIVE task definition continue to run without disruption. Existing services that reference an INACTIVE task definition can still scale up or down by modifying the service's desired count. If you want to delete a task definition revision, you must first deregister the task definition revision.

You can't use an INACTIVE task definition to run new tasks or create new services, and you can't update an existing service to reference an INACTIVE task definition. However, there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect.

At this time, INACTIVE task definitions remain discoverable in your account indefinitely. However, this behavior is subject to change in the future. We don't recommend that you rely on INACTIVE task definitions persisting beyond the lifecycle of any associated tasks and services.

You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.

Parameter Syntax

$result = $client->deregisterTaskDefinition([
    'taskDefinition' => '<string>', // REQUIRED
]);

Members
taskDefinition
Required: Yes

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

DescribeCapacityProviders

$result = $client->describeCapacityProviders([/* ... */]);
$promise = $client->describeCapacityProvidersAsync([/* ... */]);

Describes one or more of your capacity providers.

Parameter Syntax

$result = $client->describeCapacityProviders([
    'capacityProviders' => ['<string>', ...],
    'include' => ['<string>', ...],
    'maxResults' => <integer>,
    'nextToken' => '<string>',

Parameter Details

Members
capacityProviders
Type: Array of strings

The short name or full Amazon Resource Name (ARN) of one or more capacity providers. Up to 100 capacity providers can be described in an action.

include
Type: Array of strings

Specifies whether or not you want to see the resource tags for the capacity provider. If TAGS is specified, the tags are included in the response. If this field is omitted, tags aren't included in the response.

maxResults
Type: int

The maximum number of account setting results returned by DescribeCapacityProviders in paginated output. When this parameter is used, DescribeCapacityProviders only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeCapacityProviders request with the returned nextToken value. This value can be between 1 and 10. If this parameter is not used, then DescribeCapacityProviders returns up to 10 results and a nextToken value if applicable.

nextToken
Type: string

The nextToken value returned from a previous paginated DescribeCapacityProviders request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value.

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

DescribeTaskDefinition

$result = $client->describeTaskDefinition([/* ... */]);
$promise = $client->describeTaskDefinitionAsync([/* ... */]);

Describes a task definition. You can specify a family and revision to find information about a specific task definition, or you can simply specify the family to find the latest ACTIVE revision in that family.

You can only describe INACTIVE task definitions while an active task or service references them.

Parameter Syntax

$result = $client->describeTaskDefinition([
    'include' => ['<string>', ...],
    'taskDefinition' => '<string>', // REQUIRED
]);

Parameter Details

Members
include
Type: Array of strings

Result Details

Members
tags
Type: Array of Tag structures

The metadata that's applied to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskDefinition
Type: TaskDefinition structure

The full task definition description.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

    'name' => 'serviceLongArnFormat|taskLongArnFormat|containerInstanceLongArnFormat|awsvpcTrunking|containerInsights|fargateFIPSMode|tagResourceAuthorization|fargateTaskRetirementWaitPeriod|guardDutyActivate',
    'nextToken' => '<string>',
    'principalArn' => '<string>',
    'value' => '<string>',
]);

Parameter Details

Members
effectiveSettings
Type: boolean

Determines whether to return the effective settings. If true, the account settings for the root user or the default setting for the principalArn are returned. If false, the account settings for the principalArn are returned if they're set. Otherwise, no account settings are returned.

maxResults
Type: int

The maximum number of account setting results returned by ListAccountSettings in paginated output. When this parameter is used, ListAccountSettings only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListAccountSettings request with the returned nextToken value. This value can be between 1 and 10. If this parameter isn't used, then ListAccountSettings returns up to 10 results and a nextToken value if applicable.

name
Type: string

The name of the account setting you want to list the settings for.

nextToken
Type: string

The nextToken value returned from a ListAccountSettings request indicating that more results are available to fulfill the request and further calls will be needed. If maxResults was provided, it's possible the number of results to be fewer than maxResults.

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

principalArn
Type: string

The ARN of the principal, which can be a user, role, or the root user. If this field is omitted, the account settings are listed only for the authenticated user.

Federated users assume the account setting of the root user and can't have explicit account settings set for them.

value
Type: string

The value of the account settings to filter results with. You must also specify an account setting name to use this parameter.

Result Syntax

[
    'nextToken' => '<string>',
    'settings' => [
        [

    ],
]

Result Details

Members
nextToken
Type: string

The nextToken value to include in a future ListAccountSettings request. When the results of a ListAccountSettings request exceed maxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

settings
Type: Array of Setting structures

The account settings for the resource.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ListAttributes

$result = $client->listAttributes([/* ... */]);
$promise = $client->listAttributesAsync([/* ... */]);

Lists the attributes for Amazon ECS resources within a specified target type and cluster. When you specify a target type and cluster, ListAttributes returns a list of attribute objects, one for each attribute on each resource. You can filter the list of results to a single attribute name to only return results that have that name. You can also filter the results by attribute name and value. You can do this, for example, to see which container instances in a cluster are running a Linux AMI (ecs.os-type=linux).

Parameter Syntax

The container instance ID or full ARN of the container instance to use when filtering the ListTasks results. Specifying a containerInstance limits the results to tasks that belong to that container instance.

desiredStatus
Type: string

The task desired status to use when filtering the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon ECS has set the desired status to STOPPED. This can be useful for debugging tasks that aren't starting properly or have died or finished. The default status filter is RUNNING, which shows tasks that Amazon ECS has set the desired status to RUNNING.

Although you can filter results based on a desired status of PENDING, this doesn't return any results. Amazon ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING).

family
Type: string

The name of the task definition family to use when filtering the ListTasks results. Specifying a family limits the results to tasks that belong to that family.

launchType
Type: string

The launch type to use when filtering the ListTasks results.

maxResults
Type: int

The maximum number of task results that ListTasks returned in paginated output. When this parameter is used, ListTasks only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListTasks request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListTasks returns up to 100 results and a nextToken value if applicable.

nextToken
Type: string

The nextToken value returned from a ListTasks request indicating that more results are available to fulfill the request and further calls will be needed. If maxResults was provided, it's possible the number of results to be fewer than maxResults.

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

serviceName
Type: string

The name of the service to use when filtering the ListTasks results. Specifying a serviceName limits the results to tasks that belong to that service.

startedBy
Type: string

The startedBy value to filter the task results with. Specifying a startedBy value limits the results to tasks that were started with that value.

When you specify startedBy as the filter, it must be the only filter that you use.

If you change the root user account setting, the default settings are reset for users and roles that do not have specified individual account settings. For more information, see Account Settings in the Amazon Elastic Container Service Developer Guide.

Parameter Syntax

$result = $client->putAccountSetting([
    'name' => 'serviceLongArnFormat|taskLongArnFormat|containerInstanceLongArnFormat|awsvpcTrunking|containerInsights|fargateFIPSMode|tagResourceAuthorization|fargateTaskRetirementWaitPeriod|guardDutyActivate', // REQUIRED
    'principalArn' => '<string>',
    'value' => '<string>', // REQUIRED
]);

Parameter Details

Members
name
Required: Yes
Type: string

The Amazon ECS account setting name to modify.

The following are the valid values for the account setting name.

  • serviceLongArnFormat - When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging.

  • taskLongArnFormat - When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging.

  • containerInstanceLongArnFormat - When modified, the Amazon Resource Name (ARN) and resource ID format of the resource type for a specified user, role, or the root user for an account is affected. The opt-in and opt-out account setting must be set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is defined by the opt-in status of the user or role that created the resource. You must turn on this setting to use Amazon ECS features such as resource tagging.

  • awsvpcTrunking - When modified, the elastic network interface (ENI) limit for any new container instances that support the feature is changed. If awsvpcTrunking is turned on, any new container instances that support the feature are launched have the increased ENI limits available to them. For more information, see Elastic Network Interface Trunking in the Amazon Elastic Container Service Developer Guide.

  • containerInsights - When modified, the default setting indicating whether Amazon Web Services CloudWatch Container Insights is turned on for your clusters is changed. If containerInsights is turned on, any new clusters that are created will have Container Insights turned on unless you disable it during cluster creation. For more information, see CloudWatch Container Insights in the Amazon Elastic Container Service Developer Guide.

  • dualStackIPv6 - When turned on, when using a VPC in dual stack mode, your tasks using the awsvpc network mode can have an IPv6 address assigned. For more information on using IPv6 with tasks launched on Amazon EC2 instances, see Using a VPC in dual-stack mode. For more information on using IPv6 with tasks launched on Fargate, see Using a VPC in dual-stack mode.

  • fargateFIPSMode - If you specify fargateFIPSMode, Fargate FIPS 140 compliance is affected.

  • fargateTaskRetirementWaitPeriod - When Amazon Web Services determines that a security or infrastructure update is needed for an Amazon ECS task hosted on Fargate, the tasks need to be stopped and new tasks launched to replace them. Use fargateTaskRetirementWaitPeriod to configure the wait time to retire a Fargate task. For information about the Fargate tasks maintenance, see Amazon Web Services Fargate task maintenance in the Amazon ECS Developer Guide.

  • tagResourceAuthorization - Amazon ECS is introducing tagging authorization for resource creation. Users must have permissions for actions that create the resource, such as ecsCreateCluster. If tags are specified when you create a resource, Amazon Web Services performs additional authorization to verify if users or roles have permissions to create tags. Therefore, you must grant explicit permissions to use the ecs:TagResource action. For more information, see Grant permission to tag resources on creation in the Amazon ECS Developer Guide.

  • guardDutyActivate - The guardDutyActivate parameter is read-only in Amazon ECS and indicates whether Amazon ECS Runtime Monitoring is enabled or disabled by your security administrator in your Amazon ECS account. Amazon GuardDuty controls this account setting on your behalf. For more information, see Protecting Amazon ECS workloads with Amazon ECS Runtime Monitoring.

principalArn
Type: string

The ARN of the principal, which can be a user, role, or the root user. If you specify the root user, it modifies the account setting for all users, roles, and the root user of the account unless a user or role explicitly overrides these settings. If this field is omitted, the setting is changed only for the authenticated user.

You must use the root user when you set the Fargate wait time (fargateTaskRetirementWaitPeriod).

Federated users assume the account setting of the root user and can't have explicit account settings set for them.

value
Required: Yes
Type: string

The account setting value for the specified principal ARN. Accepted values are enabled, disabled, on, and off.

When you specify fargateTaskRetirementWaitPeriod for the name, the following are the valid values:

  • 0 - Amazon Web Services sends the notification, and immediately retires the affected tasks.

  • 7 - Amazon Web Services sends the notification, and waits 7 calendar days to retire the tasks.

  • 14 - Amazon Web Services sends the notification, and waits 14 calendar days to retire the tasks.

PutClusterCapacityProviders

$result = $client->putClusterCapacityProviders([/* ... */]);
$promise = $client->putClusterCapacityProvidersAsync([/* ... */]);

Modifies the available capacity providers and the default capacity provider strategy for a cluster.

You must specify both the available capacity providers and a default capacity provider strategy for the cluster. If the specified cluster has existing capacity providers associated with it, you must specify all existing capacity providers in addition to any new ones you want to add. Any existing capacity providers that are associated with a cluster that are omitted from a PutClusterCapacityProviders API call will be disassociated with the cluster. You can only disassociate an existing capacity provider from a cluster if it's not being used by any existing tasks.

When creating a service or running a task on a cluster, if no capacity provider or launch type is specified, then the cluster's default capacity provider strategy is used. We recommend that you define a default capacity provider strategy for your cluster. However, you must specify an empty array ([]) to bypass defining a default strategy.

Parameter Syntax

$result = $client->putClusterCapacityProviders([
    'capacityProviders' => ['<string>', ...], // REQUIRED
    'cluster' => '<string>', // REQUIRED
    'defaultCapacityProviderStrategy' => [ // REQUIRED

        // ...
    ],
]);

Parameter Details

Members
capacityProviders
Required: Yes
Type: Array of strings

The name of one or more capacity providers to associate with the cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

cluster
Required: Yes
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster to modify the capacity provider settings for. If you don't specify a cluster, the default cluster is assumed.

defaultCapacityProviderStrategy
Required: Yes
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to use by default for the cluster.

When creating a service or running a task on a cluster, if no capacity provider or launch type is specified then the default capacity provider strategy for the cluster is used.

A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

Type: Array of Attribute structures

The container instance attributes that this container instance supports.

cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster to register your container instance with. If you do not specify a cluster, the default cluster is assumed.

containerInstanceArn
Type: string

The ARN of the container instance (if it was previously registered).

instanceIdentityDocument
Type: string

The instance identity document for the EC2 instance to register. This document can be found by running the following command from the instance: curl http://169.254.169.254/latest/dynamic/instance-identity/document/

instanceIdentityDocumentSignature
Type: string

The instance identity document signature for the EC2 instance to register. This signature can be found by running the following command from the instance: curl http://169.254.169.254/latest/dynamic/instance-identity/signature/

platformDevices
Type: Array of PlatformDevice structures

The devices that are available on the container instance. The only supported device type is a GPU.

tags
Type: Array of Tag structures

The metadata that you apply to the container instance to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

totalResources
Type: Array of Resource structures

The resources available on the instance.

versionInfo
Type: VersionInfo structure

The version information for the Amazon ECS container agent and Docker daemon that runs on the container instance.

Result Details

Members
containerInstance
Type: ContainerInstance structure

The container instance that was registered.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

RegisterTaskDefinition

$result = $client->registerTaskDefinition([/* ... */]);
$promise = $client->registerTaskDefinitionAsync([/* ... */]);

Registers a new task definition from the supplied family and containerDefinitions. Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.

You can specify a role for your task with the taskRoleArn parameter. When you specify a role for a task, its containers can then use the latest versions of the CLI or SDKs to make API requests to the Amazon Web Services services that are specified in the policy that's associated with the role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run reference. If you specify the awsvpc network mode, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

Parameter Details

Members
containerDefinitions
Required: Yes
Type: Array of ContainerDefinition structures

A list of container definitions in JSON format that describe the different containers that make up your task.

cpu
Type: string

The number of CPU units used by the task. It can be expressed as an integer using CPU units (for example, 1024) or as a string using vCPUs (for example, 1 vCPU or 1 vcpu) in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.

Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.

If you're using the EC2 launch type, this field is optional. Supported values are between 128 CPU units (0.125 vCPUs) and 10240 CPU units (10 vCPUs). If you do not specify a value, the parameter is ignored.

If you're using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the memory parameter:

The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.

ephemeralStorage
Type: EphemeralStorage structure

The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide.

For tasks using the Fargate launch type, the task requires the following platforms:

  • Linux platform version 1.4.0 or later.

  • Windows platform version 1.0.0 or later.

executionRoleArn
Type: string

The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide.

family
Required: Yes
Type: string

You must specify a family for a task definition. You can use it track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

inferenceAccelerators
Type: Array of InferenceAccelerator structures

The Elastic Inference accelerators to use for the containers in the task.

ipcMode
Type: string

The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference.

If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.

If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

  • For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

  • For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

This parameter is not supported for Windows containers or tasks run on Fargate.

memory
Type: string

The amount of memory (in MiB) used by the task. It can be expressed as an integer using MiB (for example ,1024) or as a string using GB (for example, 1GB or 1 GB) in a task definition. String values are converted to an integer indicating the MiB when the task definition is registered.

Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.

If using the EC2 launch type, this field is optional.

If using the Fargate launch type, this field is required and you must use one of the following values. This determines your range of supported values for the cpu parameter.

The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.

  • 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)

  • 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)

  • 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)

  • Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU)

  • Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU)

  • Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU)

    This option requires Linux platform 1.4.0 or later.

  • Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU)

    This option requires Linux platform 1.4.0 or later.

networkMode
Type: string

The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.

For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

For more information, see Network settings in the Docker run reference.

pidMode
Type: string

The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

If task is specified, all containers within the specified task share the same process namespace.

If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference.

If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

placementConstraints
Type: Array of TaskDefinitionPlacementConstraint structures

An array of placement constraint objects to use for the task. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.

proxyConfiguration
Type: ProxyConfiguration structure

The configuration details for the App Mesh proxy.

For tasks hosted on Amazon EC2 instances, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS-optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized AMI versions in the Amazon Elastic Container Service Developer Guide.

requiresCompatibilities
Type: Array of strings

The task launch type that Amazon ECS validates the task definition against. A client exception is returned if the task definition doesn't validate against the compatibilities specified. If no value is specified, the parameter is omitted from the response.

runtimePlatform
Type: RuntimePlatform structure

The operating system that your tasks definitions run on. A platform family is specified only for tasks using the Fargate launch type.

When you specify a task definition in a service, this value must match the runtimePlatform value of the service.

tags
Type: Array of Tag structures

The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskRoleArn
Type: string

The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

volumes
Type: Array of Volume structures

A list of volume definitions in JSON format that containers in your task might use.

RunTask

$result = $client->runTask([/* ... */]);
$promise = $client->runTaskAsync([/* ... */]);

Starts a new task using the specified task definition.

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.

Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.

Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

The Amazon ECS API follows an eventual consistency model. This is because of the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.

To manage eventual consistency, you can do the following:

  • Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.

  • Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

Parameter Details

Members
capacityProviderStrategy
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to use for the task.

If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType.

A capacity provider strategy may contain a maximum of 6 capacity providers.

clientToken
Type: string

An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 64 characters are allowed. The valid characters are characters in the range of 33-126, inclusive. For more information, see Ensuring idempotency.

cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster to run your task on. If you do not specify a cluster, the default cluster is assumed.

count
Type: int

The number of instantiations of the specified task to place on your cluster. You can specify up to 10 tasks for each call.

enableECSManagedTags
Type: boolean

Specifies whether to use Amazon ECS managed tags for the task. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

enableExecuteCommand
Type: boolean

Determines whether to use the execute command functionality for the containers in this task. If true, this enables execute command functionality on all containers in the task.

If true, then the task definition must have a task role, or you must provide one as an override.

group
Type: string

The name of the task group to associate with the task. The default value is the family name of the task definition (for example, family:my-family-name).

launchType
Type: string

The infrastructure to run your standalone task on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.

Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide.

The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.

The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.

A task can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType.

networkConfiguration
Type: NetworkConfiguration structure

The network configuration for the task. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide.

overrides
Type: TaskOverride structure

A list of container overrides in JSON format that specify the name of a container in the specified task definition and the overrides it should receive. You can override the default command for a container (that's specified in the task definition or Docker image) with a command override. You can also override existing environment variables (that are specified in the task definition or Docker image) on a container or add new environment variables to it with an environment override.

A total of 8192 characters are allowed for overrides. This limit includes the JSON formatting characters of the override structure.

placementConstraints
Type: Array of PlacementConstraint structures

An array of placement constraint objects to use for the task. You can specify up to 10 constraints for each task (including constraints in the task definition and those specified at runtime).

placementStrategy
Type: Array of PlacementStrategy structures

The placement strategy objects to use for the task. You can specify a maximum of 5 strategy rules for each task.

platformVersion
Type: string

The platform version the task uses. A platform version is only specified for tasks hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

propagateTags
Type: string

Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.

An error will be received if you specify the SERVICE option when running a task.

referenceId
Type: string

The reference ID to use for the task. The reference ID can have a maximum length of 1024 characters.

startedBy
Type: string

An optional tag specified when a task is started. For example, if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 128 letters (uppercase and lowercase), numbers, hyphens (-), and underscores (_) are allowed.

If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

tags
Type: Array of Tag structures

The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskDefinition
Required: Yes
Type: string

The family and revision (family:revision) or full ARN of the task definition to run. If a revision isn't specified, the latest ACTIVE revision is used.

The full ARN value must match the value that you specified as the Resource of the principal's permissions policy.

When you specify a task definition, you must either specify a specific revision, or all revisions in the ARN.

To specify a specific revision, include the revision number in the ARN. For example, to specify revision 2, use arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:2.

To specify all revisions, use the wildcard (*) in the ARN. For example, to specify all revisions, use arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:*.

For more information, see Policy Resources for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

volumeConfigurations
Type: Array of TaskVolumeConfiguration structures

The details of the volume that was configuredAtLaunch. You can configure the size, volumeType, IOPS, throughput, snapshot and encryption in in TaskManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition.

Result Details

Members
failures
Type: Array of Failure structures

Any failures associated with the call.

For information about how to address failures, see Service event messages and API failure reasons in the Amazon Elastic Container Service Developer Guide.

tasks
Type: Array of Task structures

A full description of the tasks that were run. The tasks that were successfully placed on your cluster are described here.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

UnsupportedFeatureException:

The specified task isn't supported in this Region.

PlatformUnknownException:

The specified platform version doesn't exist.

PlatformTaskDefinitionIncompatibilityException:

The specified platform version doesn't satisfy the required capabilities of the task definition.

AccessDeniedException:

You don't have authorization to perform the requested action.

BlockedException:

Your Amazon Web Services account was blocked. For more information, contact Amazon Web Services Support.

ConflictException:

The RunTask request could not be processed due to conflicts. The provided clientToken is already in use with a different RunTask request. The resourceIds are the existing task ARNs which are already associated with the clientToken.

To fix this issue:

  • Run RunTask with a unique clientToken.

  • Run RunTask with the clientToken and the original set of parameters

Examples

Example 1: To run a task on your default cluster

This example runs the specified task definition on your default cluster.

$result = $client->runTask([

StartTask

$result = $client->startTask([/* ... */]);
$promise = $client->startTaskAsync([/* ... */]);

Starts a new task from the specified task definition on the specified container instance or instances.

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

Alternatively, you can use RunTask to place tasks for you. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

Parameter Details

Members
cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster where to start your task. If you do not specify a cluster, the default cluster is assumed.

containerInstances
Required: Yes
Type: Array of strings

The container instance IDs or full ARN entries for the container instances where you would like to place your task. You can specify up to 10 container instances.

enableECSManagedTags
Type: boolean

Specifies whether to use Amazon ECS managed tags for the task. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

enableExecuteCommand
Type: boolean

Whether or not the execute command functionality is turned on for the task. If true, this turns on the execute command functionality on all containers in the task.

group
Type: string

The name of the task group to associate with the task. The default value is the family name of the task definition (for example, family:my-family-name).

networkConfiguration
Type: NetworkConfiguration structure

The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

overrides
Type: TaskOverride structure

A list of container overrides in JSON format that specify the name of a container in the specified task definition and the overrides it receives. You can override the default command for a container (that's specified in the task definition or Docker image) with a command override. You can also override existing environment variables (that are specified in the task definition or Docker image) on a container or add new environment variables to it with an environment override.

A total of 8192 characters are allowed for overrides. This limit includes the JSON formatting characters of the override structure.

propagateTags
Type: string

Specifies whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.

referenceId
Type: string

The reference ID to use for the task.

startedBy
Type: string

An optional tag specified when a task is started. For example, if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 36 letters (uppercase and lowercase), numbers, hyphens (-), and underscores (_) are allowed.

If a task is started by an Amazon ECS service, the startedBy parameter contains the deployment ID of the service that starts it.

tags
Type: Array of Tag structures

The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskDefinition
Required: Yes
Type: string

The family and revision (family:revision) or full ARN of the task definition to start. If a revision isn't specified, the latest ACTIVE revision is used.

volumeConfigurations
Type: Array of TaskVolumeConfiguration structures

The details of the volume that was configuredAtLaunch. You can configure the size, volumeType, IOPS, throughput, snapshot and encryption in TaskManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition.

Result Details

Members
failures
Type: Array of Failure structures

Any failures associated with the call.

tasks
Type: Array of Task structures

A full description of the tasks that were started. Each task that was successfully placed on your container instances is described.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

UnsupportedFeatureException:

The specified task isn't supported in this Region.

StopTask

$result = $client->stopTask([/* ... */]);
$promise = $client->stopTaskAsync([/* ... */]);

Stops a running task. Any tags associated with the task will be deleted.

When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM value and a default 30-second timeout, after which the SIGKILL value is sent and the containers are forcibly stopped. If the container handles the SIGTERM value gracefully and exits within 30 seconds from receiving it, no SIGKILL value is sent.

The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

Parameter Syntax

$result = $client->stopTask([
    'cluster' => '<string>',
    'reason' => '<string>',
    'task' => '<string>', // REQUIRED
]);

Parameter Details

Members
cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the task to stop. If you do not specify a cluster, the default cluster is assumed.

reason
Type: string

An optional message specified when a task is stopped. For example, if you're using a custom scheduler, you can use this parameter to specify the reason for stopping the task here, and the message appears in subsequent DescribeTasks API operations on this task.

task
Required: Yes
Type: string

The task ID of the task to stop.

tags
Required: Yes
Type: Array of Tag structures

The tags to add to the resource. A tag is an array of key-value pairs.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

serviceConnectDefaults

Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

UpdateContainerAgent

$result = $client->updateContainerAgent([/* ... */]);
$promise = $client->updateContainerAgentAsync([/* ... */]);

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent doesn't interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.

The UpdateContainerAgent API isn't supported for container instances using the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI. To update the container agent, you can update the ecs-init package. This updates the agent. For more information, see Updating the Amazon ECS container agent in the Amazon Elastic Container Service Developer Guide.

Agent updates with the UpdateContainerAgent API operation do not apply to Windows container instances. We recommend that you launch new container instances to update the agent version in your Windows clusters.

The UpdateContainerAgent API requires an Amazon ECS-optimized AMI or Amazon Linux AMI with the ecs-init service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually updating the Amazon ECS container agent in the Amazon Elastic Container Service Developer Guide.

containerInstance
Type: ContainerInstance structure

The container instance that the container agent was updated for.

Errors

ServerException:

These errors are usually caused by a server issue.

ClientException:

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

InvalidParameterException:

The specified parameter isn't valid. Review the available parameters for the API request.

ClusterNotFoundException:

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

UpdateInProgressException:

There's already a current Amazon ECS container agent update in progress on the container instance that's specified. If the container agent becomes disconnected while it's in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.

NoUpdateAvailableException:

There's no update available for this Amazon ECS container agent. This might be because the agent is already running the latest version or because it's so old that there's no update path to the current version.

MissingVersionException:

Amazon ECS can't determine the current version of the Amazon ECS container agent on the container instance and doesn't have enough information to proceed with an update. This could be because the agent running on the container instance is a previous or custom version that doesn't use our version information.

UpdateContainerInstancesState

$result = $client->updateContainerInstancesState([/* ... */]);
$promise = $client->updateContainerInstancesStateAsync([/* ... */]);

Modifies the status of an Amazon ECS container instance.

Once a container instance has reached an ACTIVE state, you can change the status of a container instance to DRAINING to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.

A container instance can't be changed to DRAINING until it has reached an ACTIVE status. If the instance is in any other status, an error will be received.

When you set a container instance to DRAINING, Amazon ECS prevents new tasks from being scheduled for placement on the container instance and replacement service tasks are started on other container instances in the cluster if the resources are available. Service tasks on the container instance that are in the PENDING state are stopped immediately.

Service tasks on the container instance that are in the RUNNING state are stopped and replaced according to the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent. You can change the deployment configuration of your service using UpdateService.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during task replacement. For example, desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. If the minimum is 100%, the service scheduler can't remove existing tasks until the replacement tasks are considered healthy. Tasks for services that do not use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during task replacement. You can use this to define the replacement batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four tasks to be drained, provided that the cluster resources required to do this are available. If the maximum is 100%, then replacement tasks can't start until the draining tasks have stopped.

Any PENDING or RUNNING tasks that do not belong to a service aren't affected. You must wait for them to finish or stop them manually.

A container instance has completed draining when it has no more RUNNING tasks. You can verify this using ListTasks.

When a container instance has been drained, you can set a container instance to ACTIVE status and once it has reached that status the Amazon ECS scheduler can begin scheduling tasks on the instance again.

UpdateService

$result = $client->updateService([/* ... */]);
$promise = $client->updateServiceAsync([/* ... */]);

Modifies the parameters of a service.

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

For services using the rolling update (ECS) you can update the desired count, deployment configuration, network configuration, load balancers, service registries, enable ECS managed tags option, propagate tags option, task placement constraints and strategies, and task definition. When you update any of these parameters, Amazon ECS starts new tasks with the new configuration.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide. You can update your volume configurations and trigger a new deployment. volumeConfigurations is only supported for REPLICA service and not DAEMON service. If you leave volumeConfigurations null, it doesn't trigger a new deployment. For more infomation on volumes, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

For services using the blue/green (CODE_DEPLOY) deployment controller, only the desired count, deployment configuration, health check grace period, task placement constraints and strategies, enable ECS managed tags option, and propagate tags can be updated using this API. If the network configuration, platform version, task definition, or load balancer need to be updated, create a new CodeDeploy deployment. For more information, see CreateDeployment in the CodeDeploy API Reference.

For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, health check grace period, enable ECS managed tags option, and propagate tags option, using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, create a new task set For more information, see CreateTaskSet.

You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new desiredCount parameter.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide.

If you have updated the container image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.

If your updated Docker image uses the same tag as what is in the existing task definition for your service (for example, my_image:latest), you don't need to create a new revision of your task definition. You can update the service using the forceNewDeployment option. The new tasks launched by the deployment pull the current image/tag combination from your repository when they start.

You can also update the deployment configuration of a service. When a deployment is triggered by updating the task definition of a service, the service scheduler uses the deployment configuration parameters, minimumHealthyPercent and maximumPercent, to determine the deployment strategy.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during a deployment. For example, if desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that don't use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during a deployment. You can use it to define the deployment batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available).

When UpdateService stops a task during a deployment, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout. After this, SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic.

  • Determine which of the container instances in your cluster can support your service's task definition. For example, they have the required CPU, memory, ports, and container instance attributes.

  • By default, the service scheduler attempts to balance tasks across Availability Zones in this manner even though you can choose a different placement strategy.

    • Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.

    • Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:

  • Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.

  • Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.

Parameter Details

Members
capacityProviderStrategy
Type: Array of CapacityProviderStrategyItem structures

The capacity provider strategy to update the service to use.

if the service uses the default capacity provider strategy for the cluster, the service can be updated to use one or more capacity providers as opposed to the default capacity provider strategy. However, when a service is using a capacity provider strategy that's not the default capacity provider strategy, the service can't be updated to use the cluster's default capacity provider strategy.

A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.

The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

cluster
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that your service runs on. If you do not specify a cluster, the default cluster is assumed.

deploymentConfiguration
Type: DeploymentConfiguration structure

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

desiredCount
Type: int

The number of instantiations of the task to place and keep running in your service.

enableECSManagedTags
Type: boolean

Determines whether to turn on Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide.

Only tasks launched after the update will reflect the update. To update the tags on all tasks, set forceNewDeployment to true, so that Amazon ECS starts new tasks with the updated tags.

enableExecuteCommand
Type: boolean

If true, this enables execute command functionality on all task containers.

If you do not want to override the value that was set when the service was created, you can set this to null when performing this action.

forceNewDeployment
Type: boolean

Determines whether to force a new deployment of the service. By default, deployments aren't forced. You can use this option to start a new deployment with no service definition changes. For example, you can update a service's tasks to use a newer Docker image with the same image/tag combination (my_image:latest) or to roll Fargate tasks onto a newer platform version.

healthCheckGracePeriodSeconds
Type: int

The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only valid if your service is configured to use a load balancer. If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds. During that time, the Amazon ECS service scheduler ignores the Elastic Load Balancing health check status. This grace period can prevent the ECS service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.

loadBalancers
Type: Array of LoadBalancer structures

A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.

When you add, update, or remove a load balancer configuration, Amazon ECS starts new tasks with the updated Elastic Load Balancing configuration, and then stops the old tasks when the new tasks are running.

For services that use rolling updates, you can add, update, or remove Elastic Load Balancing target groups. You can update from a single target group to multiple target groups and from multiple target groups to a single target group.

For services that use blue/green deployments, you can update Elastic Load Balancing target groups by using CreateDeployment through CodeDeploy. Note that multiple target groups are not supported for blue/green deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

For services that use the external deployment controller, you can add, update, or remove load balancers by using CreateTaskSet. Note that multiple target groups are not supported for external deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

You can remove existing loadBalancers by passing an empty list.

networkConfiguration
Type: NetworkConfiguration structure

An object representing the network configuration for the service.

placementConstraints
Type: Array of PlacementConstraint structures

An array of task placement constraint objects to update the service to use. If no value is specified, the existing placement constraints for the service will remain unchanged. If this value is specified, it will override any existing placement constraints defined for the service. To remove all existing placement constraints, specify an empty array.

You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.

placementStrategy
Type: Array of PlacementStrategy structures

The task placement strategy objects to update the service to use. If no value is specified, the existing placement strategy for the service will remain unchanged. If this value is specified, it will override the existing placement strategy defined for the service. To remove an existing placement strategy, specify an empty object.

You can specify a maximum of five strategy rules for each service.

platformVersion
Type: string

The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If a platform version is not specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

propagateTags
Type: string

Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.

Only tasks launched after the update will reflect the update. To update the tags on all tasks, set forceNewDeployment to true, so that Amazon ECS starts new tasks with the updated tags.

service
Required: Yes
Type: string

The name of the service to update.

serviceConnectConfiguration
Type: ServiceConnectConfiguration structure

The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

serviceRegistries
Type: Array of ServiceRegistry structures

The details for the service discovery registries to assign to this service. For more information, see Service Discovery.

When you add, update, or remove the service registries configuration, Amazon ECS starts new tasks with the updated service registries configuration, and then stops the old tasks when the new tasks are running.

You can remove existing serviceRegistries by passing an empty list.

taskDefinition
Type: string

The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used. If you modify the task definition with UpdateService, Amazon ECS spawns a task with the new version of the task definition and then stops an old task after the new version is running.

volumeConfigurations
Type: Array of ServiceVolumeConfiguration structures

The details of the volume that was configuredAtLaunch. You can configure the size, volumeType, IOPS, throughput, snapshot and encryption in ServiceManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition. If set to null, no new deployment is triggered. Otherwise, if this configuration differs from the existing one, it triggers a new deployment.

UpdateTaskProtection

$result = $client->updateTaskProtection([/* ... */]);
$promise = $client->updateTaskProtectionAsync([/* ... */]);

Updates the protection status of a task. You can set protectionEnabled to true to protect your task from termination during scale-in events from Service Autoscaling or deployments.

Task-protection, by default, expires after 2 hours at which point Amazon ECS clears the protectionEnabled property making the task eligible for termination by a subsequent scale-in event.

You can specify a custom expiration period for task protection from 1 minute to up to 2,880 minutes (48 hours). To specify the custom expiration period, set the expiresInMinutes property. The expiresInMinutes property is always reset when you invoke this operation for a task that already has protectionEnabled set to true. You can keep extending the protection expiration period of a task by invoking this operation repeatedly.

To learn more about Amazon ECS task protection, see Task scale-in protection in the Amazon Elastic Container Service Developer Guide .

This operation is only supported for tasks belonging to an Amazon ECS service. Invoking this operation for a standalone task will result in an TASK_NOT_VALID failure. For more information, see API failure reasons.

If you prefer to set task protection from within the container, we recommend using the Task scale-in protection endpoint.

Parameter Syntax

$result = $client->updateTaskProtection([
    'cluster' => '<string>', // REQUIRED
    'expiresInMinutes' => <integer>,
    'protectionEnabled' => true || false, // REQUIRED
    'tasks' => ['<string>', ...], // REQUIRED
]);

Parameter Details

Members
cluster
Required: Yes
Type: string

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service that the task sets exist in.

expiresInMinutes
Type: int

If you set protectionEnabled to true, you can specify the duration for task protection in minutes. You can specify a value from 1 minute to up to 2,880 minutes (48 hours). During this time, your task will not be terminated by scale-in events from Service Auto Scaling or deployments. After this time period lapses, protectionEnabled will be reset to false.

If you don’t specify the time, then the task is automatically protected for 120 minutes (2 hours).

protectionEnabled
Required: Yes
Type: boolean

Specify true to mark a task for protection and false to unset protection, making it eligible for termination.

tasks
Required: Yes
Type: Array of strings

A list of up to 10 task IDs or full ARN entries.

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

CapacityProviderStrategyItem

Description

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

A capacity provider strategy may contain a maximum of 6 capacity providers.

Members
base
Type: int

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

capacityProvider
Required: Yes
Type: string

The short name of the capacity provider.

weight
Type: int

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0, any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB, then for every one task that's run using capacityProviderA, four tasks would use capacityProviderB.

ClientException

Description

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

ClusterServiceConnectDefaults

Description

Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

Members
namespace
Type: string

The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace. When you create a service and don't specify a Service Connect configuration, this namespace is used.

ClusterServiceConnectDefaultsRequest

Description

Use this parameter to set a default Service Connect namespace. After you set a default Service Connect namespace, any new services with Service Connect turned on that are created in the cluster are added as client services in the namespace. This setting only applies to new services that set the enabled parameter to true in the ServiceConnectConfiguration. You can set the namespace of each service individually in the ServiceConnectConfiguration to override this default parameter.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

Members
namespace
Required: Yes
Type: string

The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace that's used when you create a service and don't specify a Service Connect configuration. The namespace name can include up to 1024 characters. The name is case-sensitive. The name can't include hyphens (-), tilde (~), greater than (>), less than (<), or slash (/).

If you enter an existing namespace name or ARN, then that namespace will be used. Any namespace type is supported. The namespace must be in this account and this Amazon Web Services Region.

If you enter a new name, a Cloud Map namespace will be created. Amazon ECS creates a Cloud Map namespace with the "API calls" method of instance discovery only. This instance discovery method is the "HTTP" namespace type in the Command Line Interface. Other types of instance discovery aren't used by Service Connect.

If you update the cluster with an empty string "" for the namespace name, the cluster configuration for Service Connect is removed. Note that the namespace will remain in Cloud Map and must be deleted separately.

For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide.

ContainerDefinition

Description

Container definitions are used in task definitions to describe the different containers that are launched as part of a task.

Members
command
Type: Array of strings

The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.

cpu
Type: int

The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.

This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.

You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.

Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.

On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:

  • Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.

  • Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.

On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0, which Windows interprets as 1% of one CPU.

credentialSpecs
Type: Array of strings

A list of ARNs in SSM or Amazon S3 to a credential spec (CredSpec) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions. The maximum number of ARNs is 1.

There are two formats for each ARN.

credentialspecdomainless:MyARN

You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.

Each task that runs on any container instance can join different domains.

You can use this format without joining the container instance to a domain.

credentialspec:MyARN

You use credentialspec:MyARN to provide a CredSpec for a single domain.

You must join the container instance to the domain before you start any tasks that use this task definition.

In both formats, replace MyARN with the ARN in SSM or Amazon S3.

If you provide a credentialspecdomainless:MyARN, the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.

dependsOn
Type: Array of ContainerDependency structures

The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.

For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

For tasks using the Fargate launch type, the task or service requires the following platforms:

  • Linux platform version 1.3.0 or later.

  • Windows platform version 1.0.0 or later.

disableNetworking
Type: boolean

When this parameter is true, networking is off within the container. This parameter maps to NetworkDisabled in the Create a container section of the Docker Remote API.

This parameter is not supported for Windows containers.

dnsSearchDomains
Type: Array of strings

A list of DNS search domains that are presented to the container. This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run.

This parameter is not supported for Windows containers.

dnsServers
Type: Array of strings

A list of DNS servers that are presented to the container. This parameter maps to Dns in the Create a container section of the Docker Remote API and the --dns option to docker run.

This parameter is not supported for Windows containers.

dockerLabels
Type: Associative array of custom strings keys (String) to strings

A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

dockerSecurityOptions
Type: Array of strings

A list of strings to provide custom configuration for multiple security systems. For more information about valid values, see Docker Run Security Configuration. This field isn't valid for containers in tasks using the Fargate launch type.

For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.

For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide.

This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run.

The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

For more information about valid values, see Docker Run Security Configuration.

Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

entryPoint
Type: Array of strings

Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead.

The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.

environment
Type: Array of KeyValuePair structures

The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.

We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.

environmentFiles
Type: Array of EnvironmentFile structures

A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.

You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file.

If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide.

essential
Type: boolean

If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

extraHosts
Type: Array of HostEntry structures

A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. This parameter maps to ExtraHosts in the Create a container section of the Docker Remote API and the --add-host option to docker run.

This parameter isn't supported for Windows containers or tasks that use the awsvpc network mode.

firelensConfiguration
Type: FirelensConfiguration structure

The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide.

healthCheck
Type: HealthCheck structure

The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run.

hostname
Type: string

The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run.

The hostname parameter is not supported if you're using the awsvpc network mode.

image
Type: string

The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.

  • When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.

  • Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest. For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE.

  • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

  • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

  • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

interactive
Type: boolean

When this parameter is true, you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.

links
Type: Array of strings

The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge. The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.

This parameter is not supported for Windows containers.

Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

linuxParameters
Type: LinuxParameters structure

Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities.

This parameter is not supported for Windows containers.

logConfiguration
Type: LogConfiguration structure

The log configuration specification for the container.

This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

memory
Type: int

The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

If using the Fargate launch type, this parameter is optional.

If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

memoryReservation
Type: int

The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.

If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation. If you specify memoryReservation, then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.

For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.

The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.

The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

mountPoints
Type: Array of MountPoint structures

The mount points for data volumes in your container.

This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.

Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

name
Type: string

The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.

portMappings
Type: Array of PortMapping structures

The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.

For task definitions that use the awsvpc network mode, only specify the containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

Port mappings on Windows use the NetNAT gateway address rather than localhost. There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.

This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none, then you can't specify port mappings. If the network mode of a task definition is set to host, then host ports must either be undefined or they must match the container port in the port mapping.

After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.

privileged
Type: boolean

When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run.

This parameter is not supported for Windows containers or tasks run on Fargate.

pseudoTerminal
Type: boolean

When this parameter is true, a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.

readonlyRootFilesystem
Type: boolean

When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run.

This parameter is not supported for Windows containers.

repositoryCredentials
Type: RepositoryCredentials structure

The private repository authentication credentials to use.

resourceRequirements
Type: Array of ResourceRequirement structures

The type and amount of a resource to assign to a container. The only supported resource is a GPU.

secrets
Type: Array of Secret structures

The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

startTimeout
Type: int

Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE, SUCCESS, or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.

When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.

For tasks using the Fargate launch type, the task or service requires the following platforms:

  • Linux platform version 1.3.0 or later.

  • Windows platform version 1.0.0 or later.

For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

The valid values are 2-120 seconds.

stopTimeout
Type: int

Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.

For tasks using the Fargate launch type, the task or service requires the following platforms:

  • Linux platform version 1.3.0 or later.

  • Windows platform version 1.0.0 or later.

The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.

For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

The valid values are 2-120 seconds.

systemControls
Type: Array of SystemControl structures

A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

ulimits
Type: Array of Ulimit structures

A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.

Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 65535.

This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

This parameter is not supported for Windows containers.

user
Type: string

The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run.

When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

  • user

  • user:group

  • uid

  • uid:gid

  • user:gid

  • uid:group

This parameter is not supported for Windows containers.

volumesFrom
Type: Array of VolumeFrom structures

Data volumes to mount from another container. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run.

workingDirectory
Type: string

The working directory to run commands inside the container in. This parameter maps to WorkingDir in the Create a container section of the Docker Remote API and the --workdir option to docker run.

ContainerDependency

Description

The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.

Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide.

For tasks that use the Fargate launch type, the task or service requires the following platforms:

  • Linux platform version 1.3.0 or later.

  • Windows platform version 1.0.0 or later.

For more information about how to create a container dependency, see Container dependency in the Amazon Elastic Container Service Developer Guide.

Members
condition
Required: Yes
Type: string

The dependency condition of the container. The following are the available conditions and their behavior:

  • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

  • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

  • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

  • HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.

containerName
Required: Yes
Type: string

The name of a container.

ContainerInstance

The Unix timestamp for the time when the container instance was registered.

registeredResources
Type: Array of Resource structures

For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS. This value represents the total amount of CPU and memory that can be allocated on this container instance to tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.

remainingResources
Type: Array of Resource structures

For CPU and memory resource types, this parameter describes the remaining CPU and memory that wasn't already allocated to tasks and is therefore available for new tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent (at instance registration time) and any task containers that have reserved port mappings on the host (with the host or bridge network mode). Any port that's not specified here is available for new tasks.

runningTasksCount
Type: int

The number of tasks on the container instance that have a desired status (desiredStatus) of RUNNING.

status
Type: string

The status of the container instance. The valid values are REGISTERING, REGISTRATION_FAILED, ACTIVE, INACTIVE, DEREGISTERING, or DRAINING.

If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.

The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks aren't placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container instance draining in the Amazon Elastic Container Service Developer Guide.

statusReason
Type: string

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

version
Type: long (int|float)

The version counter for the container instance. Every time a container instance experiences a change that triggers a CloudWatch event, the version counter is incremented. If you're replicating your Amazon ECS container instance state with CloudWatch Events, you can compare the version of a container instance reported by the Amazon ECS APIs with the version reported in CloudWatch Events for the container instance (inside the detail object) to verify that the version in your event stream is current.

versionInfo
Type: VersionInfo structure

The version information for the Amazon ECS container agent and Docker daemon running on the container instance.

desiredCount
Type: int

The most recent desired count of tasks that was specified for the service to deploy or maintain.

failedTasks
Type: int

The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.

id

DeploymentAlarms

Description

One of the methods which provide a way for you to quickly identify when a deployment has failed, and then to optionally roll back the failure to the last working deployment.

When the alarms are generated, Amazon ECS sets the service deployment to failed. Set the rollback parameter to have Amazon ECS to roll back your service to the last completed deployment after a failure.

You can only use the DeploymentAlarms method to detect failures when the DeploymentController is set to ECS (rolling update).

For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide .

Members

Type: Array of strings

One or more CloudWatch alarm names. Use a "," to separate the alarms.

enable
Required: Yes
Type: boolean

Determines whether to use the CloudWatch alarm option in the service deployment process.

Type: boolean

Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

DeploymentCircuitBreaker

Description

The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If it is turned on, a service deployment will transition to a failed state and stop launching new tasks. You can also configure Amazon ECS to roll back your service to the last completed deployment after a failure. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide.

For more information about API failure reasons, see API failure reasons in the Amazon Elastic Container Service Developer Guide.

Members
enable
Required: Yes
Type: boolean

Determines whether to use the deployment circuit breaker logic for the service.

Members
alarms
Type: DeploymentAlarms structure

Information about the CloudWatch alarms.

deploymentCircuitBreaker
Type: DeploymentCircuitBreaker structure

The deployment circuit breaker can only be used for services using the rolling update (ECS) deployment type.

The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

maximumPercent
Type: int

If a service is using the rolling update (ECS) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

minimumHealthyPercent
Type: int

If a service is using the rolling update (ECS) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

For services that do not use a load balancer, the following should be noted:

  • A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

  • If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

  • If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

For services that do use a load balancer, the following should be noted:

  • If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

  • If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent/100, rounded up to the nearest integer value.

If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green (CODE_DEPLOY) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

DeploymentController

Description

The deployment controller to use for the service. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

Members
type
Required: Yes
Type: string

The deployment controller type to use.

There are three deployment controller types available:

ECS

The rolling update (ECS) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.

CODE_DEPLOY

The blue/green (CODE_DEPLOY) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

EXTERNAL

The external (EXTERNAL) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

HealthCheck

Description

An object representing a container health check. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image (such as those specified in a parent image or from the image's Dockerfile). This configuration maps to the HEALTHCHECK parameter of docker run.

The Amazon ECS container agent only monitors and reports on the health checks specified in the task definition. Amazon ECS does not monitor Docker health checks that are embedded in a container image and not specified in the container definition. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image.

You can view the health status of both individual containers and a task with the DescribeTasks API operation or when viewing the task details in the console.

The health check is designed to make sure that your containers survive agent restarts, upgrades, or temporary unavailability.

Amazon ECS performs health checks on containers with the default that launched the container instance or the task.

The following describes the possible healthStatus values for a container:

  • HEALTHY-The container health check has passed successfully.

  • UNHEALTHY-The container health check has failed.

  • UNKNOWN-The container health check is being evaluated, there's no container health check defined, or Amazon ECS doesn't have the health status of the container.

The following describes the possible healthStatus values based on the container health checker status of essential containers in the task with the following priority order (high to low):

  • UNHEALTHY-One or more essential containers have failed their health check.

  • UNKNOWN-Any essential container running within the task is in an UNKNOWN state and no other essential containers have an UNHEALTHY state.

  • HEALTHY-All essential containers within the task have passed their health checks.

Consider the following task health example with 2 containers.

  • If Container1 is UNHEALTHY and Container2 is UNKNOWN, the task health is UNHEALTHY.

  • If Container1 is UNHEALTHY and Container2 is HEALTHY, the task health is UNHEALTHY.

  • If Container1 is HEALTHY and Container2 is UNKNOWN, the task health is UNKNOWN.

  • If Container1 is HEALTHY and Container2 is HEALTHY, the task health is HEALTHY.

Consider the following task health example with 3 containers.

  • If Container1 is UNHEALTHY and Container2 is UNKNOWN, and Container3 is UNKNOWN, the task health is UNHEALTHY.

  • If Container1 is UNHEALTHY and Container2 is UNKNOWN, and Container3 is HEALTHY, the task health is UNHEALTHY.

  • If Container1 is UNHEALTHY and Container2 is HEALTHY, and Container3 is HEALTHY, the task health is UNHEALTHY.

  • If Container1 is HEALTHY and Container2 is UNKNOWN, and Container3 is HEALTHY, the task health is UNKNOWN.

  • If Container1 is HEALTHY and Container2 is UNKNOWN, and Container3 is UNKNOWN, the task health is UNKNOWN.

  • If Container1 is HEALTHY and Container2 is HEALTHY, and Container3 is HEALTHY, the task health is HEALTHY.

If a task is run manually, and not as part of a service, the task will continue its lifecycle regardless of its health status. For tasks that are part of a service, if the task reports as unhealthy then the task will be stopped and the service scheduler will replace it.

The following are notes about container health check support:

  • When the Amazon ECS agent cannot connect to the Amazon ECS service, the service reports the container as UNHEALTHY.

  • The health check statuses are the "last heard from" response from the Amazon ECS agent. There are no assumptions made about the status of the container health checks.

  • Container health checks require version 1.17.0 or greater of the Amazon ECS container agent. For more information, see Updating the Amazon ECS container agent.

  • Container health checks are supported for Fargate tasks if you're using platform version 1.1.0 or greater. For more information, see Fargate platform versions.

  • Container health checks aren't supported for tasks that are part of a service that's configured to use a Classic Load Balancer.

Members
command
Required: Yes
Type: Array of strings

A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.

When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.

[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]

You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.

CMD-SHELL, curl -f http://localhost/ || exit 1

An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.

sourcePath
Type: string

When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

If you're using the Fargate launch type, the sourcePath parameter is not supported.

Members
capabilities
Type: KernelCapabilities structure

The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.

For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later.

devices
Type: Array of Device structures

Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run.

If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.

initProcessEnabled
Type: boolean

Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

maxSwap
Type: int

The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.

If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.

If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported.

If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.

sharedMemorySize
Type: int

The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.

swappiness
Type: int

This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.

If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported.

If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.

tmpfs
Type: Array of Tmpfs structures

The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

If you're using tasks that use the Fargate launch type, the tmpfs parameter isn't supported.

LoadBalancer

Description

The load balancer configuration to use with a service or task set.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide.

Members
containerName
Type: string

The name of the container (as it appears in a container definition) to associate with the load balancer.

You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

containerPort
Type: int

The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

loadBalancerName
Type: string

The name of the load balancer to associate with the Amazon ECS service or task set.

If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

targetGroupArn
Type: string

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide.

For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide.

If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance. Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

LogConfiguration

Description

The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run .

By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

Understand the following when specifying a log configuration for your containers.

  • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

    For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

    For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens.

  • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

  • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

  • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

Members
logDriver
Required: Yes
Type: string

The log driver to use for the container.

For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens.

For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide.

For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide.

If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.

options
Type: Associative array of custom strings keys (String) to strings

The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

When managed scaling is turned on, Amazon ECS manages the scale-in and scale-out actions of the Auto Scaling group. Amazon ECS manages a target tracking scaling policy using an Amazon ECS managed CloudWatch metric with the specified targetCapacity value as the target value for the metric. For more information, see Using managed scaling in the Amazon Elastic Container Service Developer Guide.

If managed scaling is off, the user must manage the scaling of the Auto Scaling group.

Members
instanceWarmupPeriod
Type: int

The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.

maximumScalingStepSize
Type: int

The maximum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter. If this parameter is omitted, the default value of 10000 is used.

minimumScalingStepSize
Type: int

The minimum number of Amazon EC2 instances that Amazon ECS will scale out at one time. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used.

When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size.

If you use a capacity provider with an Auto Scaling group configured with more than one Amazon EC2 instance type or Availability Zone, Amazon ECS will scale up by the exact minimum scaling step size value and will ignore both the maximum scaling step size as well as the capacity demand.

status
Type: string

Determines whether to use managed scaling for the capacity provider.

targetCapacity
Type: int

The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90. The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.

MissingVersionException

Description

Amazon ECS can't determine the current version of the Amazon ECS container agent on the container instance and doesn't have enough information to proceed with an update. This could be because the agent running on the container instance is a previous or custom version that doesn't use our version information.

  • This parameter is available for both the Linux and Windows operating systems.

  • The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

  • You can specify a maximum of 100 port ranges per container.

  • You do not specify a hostPortRange. The value of the hostPortRange is set as follows:

    • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

    • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

  • The containerPortRange valid values are between 1 and 65535.

  • A port can only be included in one port mapping per container.

  • You cannot specify overlapping port ranges.

  • The first port in the range must be less than last port in the range.

  • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

Members

PlacementConstraint

Description

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide.

If you're using the Fargate launch type, task placement constraints aren't supported.

Members

The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

PlacementStrategy

Description

The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide.

Members
field
Type: string

The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

type
Type: string

The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

Members

PortMapping

Description

Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.

If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

Most fields of this parameter (containerPort, hostPort, protocol) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to host, host ports must either be undefined or match the container port in the port mapping.

You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.

After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.

Members
appProtocol
Type: string

The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.

If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.

appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

containerPort
Type: int

The port number on the container that's bound to the user-specified or automatically assigned host port.

If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort.

If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort. Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.

containerPortRange
Type: string

The port number range on the container that's bound to the dynamically mapped host port range.

The following rules apply when you specify a containerPortRange:

  • You must use either the bridge network mode or the awsvpc network mode.

  • This parameter is available for both the EC2 and Fargate launch types.

  • This parameter is available for both the Linux and Windows operating systems.

  • The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

  • You can specify a maximum of 100 port ranges per container.

  • You do not specify a hostPortRange. The value of the hostPortRange is set as follows:

    • For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange. This is a static mapping strategy.

    • For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

  • The containerPortRange valid values are between 1 and 65535.

  • A port can only be included in one port mapping per container.

  • You cannot specify overlapping port ranges.

  • The first port in the range must be less than last port in the range.

  • Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports.

    For more information, see Issue #11185 on the Github website.

    For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide.

You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

hostPort
Type: int

The port number on the container instance to reserve for your container.

If you specify a containerPortRange, leave this field empty and the value of the hostPort is set as follows:

  • For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort. This is a static mapping strategy.

  • For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.

If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort.

If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.

The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.

name
Type: string

The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

protocol
Type: string

The protocol used for the port mapping. Valid values are tcp and udp. The default is tcp. protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.

The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

port
Required: Yes
Type: int

The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

Members
enabled
Required: Yes
Type: boolean

Specifies whether to use Service Connect with this service.

logConfiguration
Type: LogConfiguration structure

The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run .

By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

Understand the following when specifying a log configuration for your containers.

  • Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent.

    For tasks on Fargate, the supported log drivers are awslogs, splunk, and awsfirelens.

    For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens.

  • This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

  • For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.

  • For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

namespace
Type: string

The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect.

Each name and port mapping must be unique within the namespace.

For each ServiceConnectService, you must provide at least one clientAlias with one port.

discoveryName
Type: string

The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

ingressPortOverride
Type: int

The port number for the Service Connect proxy to listen on.

Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

Type: int

The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type.

  • gp3: 3,000 - 16,000 IOPS

  • io1: 100 - 64,000 IOPS

  • io2: 100 - 256,000 IOPS

This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for st1, sc1, or standard volume types.

This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference.

kmsKeyId
Type: string

The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

roleArn
Required: Yes
Type: string

The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

Members
containerName
Type: string

The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

containerPort
Type: int

The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

Type: string

Determines whether the account setting is on or off for the specified resource.

SystemControl

Description

A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode. Doing this has the following disadvantages:

  • For tasks that use the awsvpc network mode including Fargate, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.

  • For tasks that use the host network mode, the network namespace systemControls aren't supported.

If you're setting an IPC resource namespace to use for the containers in the task, the following conditions apply to your system controls. For more information, see IPC mode.

  • For tasks that use the host IPC mode, IPC namespace systemControls aren't supported.

  • For tasks that use the task IPC mode, IPC namespace systemControls values apply to all containers within a task.

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

Members

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

taskArn
Type: string

The Amazon Resource Name (ARN) of the task.

taskDefinitionArn
Type: string

The ARN of the task definition that creates the task.

version
Type: long (int|float)

inferenceAccelerators
Type: Array of InferenceAccelerator structures

The Elastic Inference accelerator that's associated with the task.

ipcMode
Type: string

The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference.

If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.

If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

  • For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

  • For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.

This parameter is not supported for Windows containers or tasks run on Fargate.

memory
Type: string

The amount (in MiB) of memory used by the task.

If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition.

If your tasks runs on Fargate, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the cpu parameter.

  • 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)

  • 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)

  • Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU)

    This option requires Linux platform 1.4.0 or later.

networkMode
Type: string

The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.

For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.

If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.

For more information, see Network settings in the Docker run reference.

pidMode
Type: string

The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.

If task is specified, all containers within the specified task share the same process namespace.

If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference.

If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

TaskVolumeConfiguration

Description

Configuration settings for the task volume that was configuredAtLaunch that weren't set during RegisterTaskDef.

Members
managedEBSVolume

The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

name
Required: Yes
Type: string

The name of the volume. This value must match the volume name from the Volume object in the task definition.

TimeoutConfiguration

If idleTimeout is set to a time that is less than perRequestTimeout, the connection will close when the idleTimeout is reached and not the perRequestTimeout.

Members
idleTimeoutSeconds
Type: int

The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout.

The idleTimeout default for HTTP/HTTP2/GRPC is 5 minutes.

The idleTimeout default for TCP is 1 hour.

perRequestTimeoutSeconds
Type: int

The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout. perRequestTimeout can only be set if Service Connect appProtocol isn't TCP. Only idleTimeout is allowed for TCP appProtocol.

Tmpfs

Description

The container path, mount options, and size of the tmpfs mount.

Members
containerPath
Required: Yes

The list of tmpfs volume mount options.

Valid values: "defaults" | "ro" | "rw" | "suid" | "nosuid" | "dev" | "nodev" | "exec" | "noexec" | "sync" | "async" | "dirsync" | "remount" | "mand" | "nomand" | "atime" | "noatime" | "diratime" | "nodiratime" | "bind" | "rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime" | "norelatime" | "strictatime" | "nostrictatime" | "mode" | "uid" | "gid" | "nr_inodes" | "nr_blocks" | "mpol"

size
Required: Yes
Type: int

The maximum size (in MiB) of the tmpfs volume.

Ulimit

Description

The ulimit settings to pass to the container.

Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 65535.

You can specify the ulimit settings for a container in a task definition.

Members
hardLimit
Required: Yes
Type: int

The hard limit for the ulimit type.

name
Required: Yes
Type: string

The type of the ulimit.

softLimit
Required: Yes
Type: int

The soft limit for the ulimit type.

UnsupportedFeatureException

Description

The specified task isn't supported in this Region.

Members

UpdateInProgressException

Description

There's already a current Amazon ECS container agent update in progress on the container instance that's specified. If the container agent becomes disconnected while it's in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.

Members

VersionInfo

Description

The Docker and Amazon ECS container agent version information about a container instance.

Members
agentHash
Type: string

The Git commit hash for the Amazon ECS container agent build on the amazon-ecs-agent GitHub repository.

agentVersion
Type: string

The version number of the Amazon ECS container agent.

dockerVersion
Type: string

The Docker version that's running on the container instance.

Volume

Description

The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch, dockerVolumeConfiguration, efsVolumeConfiguration, fsxWindowsFileServerVolumeConfiguration, or host. If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.

Members
configuredAtLaunch
Type: boolean

Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.

To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.

dockerVolumeConfiguration
Type: DockerVolumeConfiguration structure

This parameter is specified when you use Docker volumes.

Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.

Docker volumes aren't supported by tasks run on Fargate.

efsVolumeConfiguration
Type: EFSVolumeConfiguration structure

This parameter is specified when you use an Amazon Elastic File System file system for task storage.

fsxWindowsFileServerVolumeConfiguration

This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.

host
Type: HostVolumeProperties structure

This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\, but not D:\my\path:C:\my\path or D:\:C:\my\path.

name
Type: string

The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.

For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.

When a volume is using the efsVolumeConfiguration, the name is required.

VolumeFrom

Description

Details on a data volume from another container in the same task definition.

Members
readOnly
Type: boolean

If this value is true, the container has read-only access to the volume. If this value is false, then the container can write to the volume. The default value is false.

sourceContainer
Type: string

The name of another container within the same task definition to mount volumes from.
