hasContainerDefinitions
public final boolean hasContainerDefinitions()For responses, this returns true if the service returned a value for the ContainerDefinitions property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
containerDefinitions
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasContainerDefinitions()
method.- Returns:
- A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
-
family
The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.

IAM roles for tasks on Windows require that the
-EnableTaskIAMRole
option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.- Returns:
- The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants

networkMode
The Docker networking mode to use for the containers in the task. The valid values are
none

,awsvpc
, andhost
. If no network mode is specified, the default isbridge
.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>
orawsvpc
can be used. If the network mode is set tonone
, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. Thehost
andawsvpc
network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by thebridge
mode.With the
host
andawsvpc
network modes, exposed container ports are mapped directly to the corresponding host port (for thehost
network mode) or the attached elastic network interface port (for theawsvpc
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.
If the service returns an enum value that is not available in the current SDK version,
networkMode
will returnNetworkMode.UNKNOWN_TO_SDK_VERSION

hasInferenceAccelerators
public final boolean hasInferenceAccelerators()For responses, this returns true if the service returned a value for the InferenceAccelerators property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
inferenceAccelerators
The Elastic Inference accelerator that's associated with the task.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasInferenceAccelerators()
method.- Returns:
- The Elastic Inference accelerator that's associated with the task.

pidMode
The process namespace to use for the containers in the task. The valid values are
host
ortask
. On Fargate for Linux containers, the only valid value istask
. For example, monitoring sidecars might needpidMode
to access information about other containers running in the same task.If
host
is specified, all containers within the tasks that specified thehost
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.If the service returns an enum value that is not available in the current SDK version,

ipcMode
The IPC resource namespace to use for the containers in the task. The valid values are

. Ifhost
is specified, then all containers within the tasks that specified thehost
IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. Iftask
is specified, all containers within the specified task share the same IPC resources. Ifnone
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.
