Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Using AWS Batch, you can run batch computing workloads on the AWS Cloud. Batch computing is a common means for developers, scientists, and engineers to access large amounts of compute resources. AWS Batch utilizes the advantages of this computing workload to remove the undifferentiated heavy lifting of configuring and managing required infrastructure, while also adopting a familiar batch computing software approach. Given these advantages, AWS Batch can help you to efficiently provision resources in response to jobs submitted, thus effectively helping to eliminate capacity constraints, reduce compute costs, and deliver your results more quickly.

As a fully managed service, AWS Batch can run batch computing workloads of any scale. AWS Batch automatically provisions compute resources and optimizes workload distribution based on the quantity and scale of your specific workloads. With AWS Batch, there's no need to install or manage batch computing software. This means that you can focus your time and energy on analyzing results and solving your specific problems.

Sending a Request Using Batch

var batch = new AWS.Batch();
batch.cancelJob(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the Batch object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var batch = new AWS.Batch({apiVersion: '2016-08-10'});

You can also set the API version globally in AWS.config.apiVersions using the batch service identifier:

AWS.config.apiVersions = {
  batch: '2016-08-10',
  // other service API versions
};

var batch = new AWS.Batch();

Method Details

cancelJob(params = {}, callback) ⇒ AWS.Request

Cancels a job in an AWS Batch job queue. Jobs that are in the SUBMITTED, PENDING, or RUNNABLE state are canceled. Jobs that have progressed to STARTING or RUNNING are not canceled (but the API operation still succeeds, even if no job is canceled); these jobs must be terminated with the TerminateJob operation.

Service Reference:

Examples:

To cancel a job


/* This example cancels a job with the specified job ID. */

 var params = {
  jobId: "1d828f65-7a4d-42e8-996d-3b900ed59dc4", 
  reason: "Cancelling job."
 };
 batch.cancelJob(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
   }
   */
 });

Calling the cancelJob operation

var params = {
  jobId: 'STRING_VALUE', /* required */
  reason: 'STRING_VALUE' /* required */
};
batch.cancelJob(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobId — (String)

      The AWS Batch job ID of the job to cancel.

    • reason — (String)

      A message to attach to the job that explains the reason for canceling it. This message is returned by future DescribeJobs operations on the job. This message is also recorded in the AWS Batch activity logs.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createComputeEnvironment(params = {}, callback) ⇒ AWS.Request

Creates an AWS Batch compute environment. You can create MANAGED or UNMANAGED compute environments. MANAGED compute environments can use Amazon EC2 or AWS Fargate resources. UNMANAGED compute environments can only use EC2 resources.

In a managed compute environment, AWS Batch manages the capacity and instance types of the compute resources within the environment. This is based on the compute resource specification that you define or the launch template that you specify when you create the compute environment. You can choose either to use EC2 On-Demand Instances and EC2 Spot Instances, or to use Fargate and Fargate Spot capacity in your managed compute environment. You can optionally set a maximum price so that Spot Instances only launch when the Spot Instance price is less than a specified percentage of the On-Demand price.

Note: Multi-node parallel jobs are not supported on Spot Instances.

In an unmanaged compute environment, you can manage your own EC2 compute resources and have a lot of flexibility with how you configure your compute resources. For example, you can use custom AMI. However, you need to verify that your AMI meets the Amazon ECS container instance AMI specification. For more information, see container instance AMIs in the Amazon Elastic Container Service Developer Guide. After you have created your unmanaged compute environment, you can use the DescribeComputeEnvironments operation to find the Amazon ECS cluster that's associated with it. Then, manually launch your container instances into that Amazon ECS cluster. For more information, see Launching an Amazon ECS container instance in the Amazon Elastic Container Service Developer Guide.

Note: AWS Batch doesn't upgrade the AMIs in a compute environment after it's created. For example, it doesn't update the AMIs when a newer version of the Amazon ECS-optimized AMI is available. Therefore, you're responsible for the management of the guest operating system (including updates and security patches) and any additional application software or utilities that you install on the compute resources. To use a new AMI for your AWS Batch jobs, complete these steps:
  1. Create a new compute environment with the new AMI.
  2. Add the compute environment to an existing job queue.
  3. Remove the earlier compute environment from your job queue.
  4. Delete the earlier compute environment.

Parameters:

  • params (Object) (defaults to: {})
    • computeEnvironmentName — (String)

      The name for your compute environment. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

    • type — (String)

      The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute Environments in the AWS Batch User Guide.

      Possible values include:
      • "MANAGED"
      • "UNMANAGED"
    • state — (String)

      The state of the compute environment. If the state is ENABLED, then the compute environment accepts jobs from a queue and can scale out automatically based on queues.

      If the state is ENABLED, then the AWS Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

      If the state is DISABLED, then the AWS Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.

      Possible values include:
      • "ENABLED"
      • "DISABLED"
    • computeResources — (map)

      Details about the compute resources managed by the compute environment. This parameter is required for managed compute environments. For more information, see Compute Environments in the AWS Batch User Guide.

      • typerequired — (String)

        The type of compute environment: EC2, SPOT, FARGATE, or FARGATE_SPOT. For more information, see Compute Environments in the AWS Batch User Guide.

        If you choose SPOT, you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 Spot Fleet role in the AWS Batch User Guide.

        Possible values include:
        • "EC2"
        • "SPOT"
        • "FARGATE"
        • "FARGATE_SPOT"
      • allocationStrategy — (String)

        The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits. For more information, see Allocation Strategies in the AWS Batch User Guide.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
        BEST_FIT (default)

        AWS Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, AWS Batch will wait for the additional instances to be available. If there are not enough instances available, or if the user is hitting Amazon EC2 service limits then additional jobs aren't run until currently running jobs have completed. This allocation strategy keeps costs lower but can limit scaling. If you are using Spot Fleets with BEST_FIT then the Spot Fleet IAM Role must be specified.

        BEST_FIT_PROGRESSIVE

        AWS Batch will select additional instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types with a lower cost per unit vCPU. If additional instances of the previously selected instance types aren't available, AWS Batch will select new instance types.

        SPOT_CAPACITY_OPTIMIZED

        AWS Batch will select one or more instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

        With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch never exceeds maxvCpus by more than a single instance.

        Possible values include:
        • "BEST_FIT"
        • "BEST_FIT_PROGRESSIVE"
        • "SPOT_CAPACITY_OPTIMIZED"
      • minvCpus — (Integer)

        The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED).

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • maxvCpusrequired — (Integer)

        The maximum number of Amazon EC2 vCPUs that a compute environment can reach.

        Note: With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch will never go above maxvCpus by more than a single instance (e.g., no more than a single instance from among those specified in your compute environment).
      • desiredvCpus — (Integer)

        The desired number of Amazon EC2 vCPUS in the compute environment. AWS Batch modifies this value between the minimum and maximum values, based on job queue demand.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • instanceTypes — (Array<String>)

        The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3), or you can specify specific sizes within a family (such as c5.8xlarge). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) on the fly that match the demand of your job queues.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
        Note: When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
        Note: Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5. and R5 instance families are used.
      • imageId — (String)

        The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
        Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
      • subnetsrequired — (Array<String>)

        The VPC subnets into which the compute resources are launched. These subnets must be within the same VPC. This parameter is required for jobs running on Fargate resources, where it can contain up to 16 subnets. For more information, see VPCs and Subnets in the Amazon VPC User Guide.

      • securityGroupIds — (Array<String>)

        The Amazon EC2 security groups associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate. This parameter is required for jobs running on Fargate resources and must contain at least one security group. (Fargate does not support launch templates.) If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds will be used.

      • ec2KeyPair — (String)

        The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • instanceRole — (String)

        The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, ecsInstanceRole or arn:aws:iam::<aws_account_id>:instance-profile/ecsInstanceRole . For more information, see Amazon ECS Instance Role in the AWS Batch User Guide.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • tags — (map<String>)

        Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For AWS Batch, these take the form of "String1": "String2", where String1 is the tag key and String2 is the tag value−for example, { "Name": "AWS Batch Instance - C4OnDemand" }. This is helpful for recognizing your AWS Batch instances in the Amazon EC2 console. These tags can't be updated or removed after the compute environment has been created; any changes require creating a new compute environment and removing the old compute environment. These tags are not seen when using the AWS Batch ListTagsForResource API operation.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • placementGroup — (String)

        The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement Groups in the Amazon EC2 User Guide for Linux Instances.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • bidPercentage — (Integer)

        The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • spotIamFleetRole — (String)

        The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 Spot Fleet Role in the AWS Batch User Guide.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.

        To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot Instances not tagged on creation in the AWS Batch User Guide.

      • launchTemplate — (map)

        The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch Template Support in the AWS Batch User Guide.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
        • launchTemplateId — (String)

          The ID of the launch template.

        • launchTemplateName — (String)

          The name of the launch template.

        • version — (String)

          The version number of the launch template, $Latest, or $Default.

          If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

          Default: $Default.

      • ec2Configuration — (Array<map>)

        Provides information used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL1.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
        • imageTyperequired — (String)

          The image type to match with the instance type to select an AMI. If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized AMI is used.

          ECS_AL2

          Amazon Linux 2− Default for all AWS Graviton-based instance families (for example, C6g, M6g, R6g, and T4g) and can be used for all non-GPU instance types.

          ECS_AL2_NVIDIA

          Amazon Linux 2 (GPU)−Default for all GPU instance families (for example P4 and G4) and can be used for all non-AWS Graviton-based instance types.

          ECS_AL1

          Amazon Linux−Default for all non-GPU, non-AWS Graviton instance families. Amazon Linux is reaching the end-of-life of standard support. For more information, see Amazon Linux AMI.

        • imageIdOverride — (String)

          The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.

    • serviceRole — (String)

      The full Amazon Resource Name (ARN) of the IAM role that allows AWS Batch to make calls to other AWS services on your behalf. For more information, see AWS Batch service IAM role in the AWS Batch User 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.

      Note: Depending on how you created your AWS Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, AWS Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.
    • tags — (map<String>)

      The tags that you apply to the compute environment to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging AWS Resources in AWS General Reference.

      These tags can be updated or removed using the TagResource and UntagResource API operations. These tags don't propagate to the underlying compute resources.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • computeEnvironmentName — (String)

        The name of the compute environment. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

      • computeEnvironmentArn — (String)

        The Amazon Resource Name (ARN) of the compute environment.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createJobQueue(params = {}, callback) ⇒ AWS.Request

Creates an AWS Batch job queue. When you create a job queue, you associate one or more compute environments to the queue and assign an order of preference for the compute environments.

You also set a priority to the job queue that determines the order in which the AWS Batch scheduler places jobs onto its associated compute environments. For example, if a compute environment is associated with more than one job queue, the job queue with a higher priority is given preference for scheduling jobs to that compute environment.

Service Reference:

Examples:

To create a job queue with a single compute environment


/* This example creates a job queue called LowPriority that uses the M4Spot compute environment. */

 var params = {
  computeEnvironmentOrder: [
     {
    computeEnvironment: "M4Spot", 
    order: 1
   }
  ], 
  jobQueueName: "LowPriority", 
  priority: 1, 
  state: "ENABLED"
 };
 batch.createJobQueue(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    jobQueueArn: "arn:aws:batch:us-east-1:012345678910:job-queue/LowPriority", 
    jobQueueName: "LowPriority"
   }
   */
 });

To create a job queue with multiple compute environments


/* This example creates a job queue called HighPriority that uses the C4OnDemand compute environment with an order of 1 and the M4Spot compute environment with an order of 2. */

 var params = {
  computeEnvironmentOrder: [
     {
    computeEnvironment: "C4OnDemand", 
    order: 1
   }, 
     {
    computeEnvironment: "M4Spot", 
    order: 2
   }
  ], 
  jobQueueName: "HighPriority", 
  priority: 10, 
  state: "ENABLED"
 };
 batch.createJobQueue(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    jobQueueArn: "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority", 
    jobQueueName: "HighPriority"
   }
   */
 });

Calling the createJobQueue operation

var params = {
  computeEnvironmentOrder: [ /* required */
    {
      computeEnvironment: 'STRING_VALUE', /* required */
      order: 'NUMBER_VALUE' /* required */
    },
    /* more items */
  ],
  jobQueueName: 'STRING_VALUE', /* required */
  priority: 'NUMBER_VALUE', /* required */
  state: ENABLED | DISABLED,
  tags: {
    '<TagKey>': 'STRING_VALUE',
    /* '<TagKey>': ... */
  }
};
batch.createJobQueue(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobQueueName — (String)

      The name of the job queue. Up to 128 letters (uppercase and lowercase), numbers, and underscores are allowed.

    • state — (String)

      The state of the job queue. If the job queue state is ENABLED, it is able to accept jobs. If the job queue state is DISABLED, new jobs can't be added to the queue, but jobs already in the queue can finish.

      Possible values include:
      • "ENABLED"
      • "DISABLED"
    • priority — (Integer)

      The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments cannot be mixed.

    • computeEnvironmentOrder — (Array<map>)

      The set of compute environments mapped to a job queue and their order relative to each other. The job scheduler uses this parameter to determine which compute environment should run a specific job. Compute environments must be in the VALID state before you can associate them with a job queue. You can associate up to three compute environments with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

      Note: All compute environments that are associated with a job queue must share the same architecture. AWS Batch doesn't support mixing compute environment architecture types in a single job queue.
      • orderrequired — (Integer)

        The order of the compute environment. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first.

      • computeEnvironmentrequired — (String)

        The Amazon Resource Name (ARN) of the compute environment.

    • tags — (map<String>)

      The tags that you apply to the job queue to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging your AWS Batch resources in AWS Batch User Guide.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • jobQueueName — (String)

        The name of the job queue.

      • jobQueueArn — (String)

        The Amazon Resource Name (ARN) of the job queue.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deleteComputeEnvironment(params = {}, callback) ⇒ AWS.Request

Deletes an AWS Batch compute environment.

Before you can delete a compute environment, you must set its state to DISABLED with the UpdateComputeEnvironment API operation and disassociate it from any job queues with the UpdateJobQueue API operation. Compute environments that use AWS Fargate resources must terminate all active jobs on that compute environment before deleting the compute environment. If this isn't done, the compute environment will end up in an invalid state.

});

Parameters:

  • params (Object) (defaults to: {})
    • computeEnvironments — (Array<String>)

      A list of up to 100 compute environment names or full Amazon Resource Name (ARN) entries.

    • maxResults — (Integer)

      The maximum number of cluster results returned by DescribeComputeEnvironments in paginated output. When this parameter is used, DescribeComputeEnvironments 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 DescribeComputeEnvironments request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeComputeEnvironments returns up to 100 results and a nextToken value if applicable.

    • nextToken — (String)

      The nextToken value returned from a previous paginated DescribeComputeEnvironments 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 value is null when there are no more results to return.

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

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • computeEnvironments — (Array<map>)

        The list of compute environments.

        • computeEnvironmentNamerequired — (String)

          The name of the compute environment. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

        • computeEnvironmentArnrequired — (String)

          The Amazon Resource Name (ARN) of the compute environment.

        • ecsClusterArnrequired — (String)

          The Amazon Resource Name (ARN) of the underlying Amazon ECS cluster used by the compute environment.

        • tags — (map<String>)

          The tags applied to the compute environment.

        • type — (String)

          The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute Environments in the AWS Batch User Guide.

          Possible values include:
          • "MANAGED"
          • "UNMANAGED"
        • state — (String)

          The state of the compute environment. The valid values are ENABLED or DISABLED.

          If the state is ENABLED, then the AWS Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

          If the state is DISABLED, then the AWS Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.

          Possible values include:
          • "ENABLED"
          • "DISABLED"
        • status — (String)

          The current status of the compute environment (for example, CREATING or VALID).

          Possible values include:
          • "CREATING"
          • "UPDATING"
          • "DELETING"

          • "INVALID"
        • statusReason — (String)

          A short, human-readable string to provide additional details about the current status of the compute environment.

        • computeResources — (map)

          The compute resources defined for the compute environment. For more information, see Compute Environments in the AWS Batch User Guide.

          • typerequired — (String)

            The type of compute environment: EC2, SPOT, FARGATE, or FARGATE_SPOT. For more information, see Compute Environments in the AWS Batch User Guide.

            If you choose SPOT, you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 Spot Fleet role in the AWS Batch User Guide.

            Possible values include:
            • "EC2"
            • "SPOT"
            • "FARGATE"
            • "FARGATE_SPOT"

            The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits. For more information, see Allocation Strategies in the AWS Batch User Guide.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
            BEST_FIT (default)

            AWS Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, AWS Batch will wait for the additional instances to be available. If there are not enough instances available, or if the user is hitting Amazon EC2 service limits then additional jobs aren't run until currently running jobs have completed. This allocation strategy keeps costs lower but can limit scaling. If you are using Spot Fleets with BEST_FIT then the Spot Fleet IAM Role must be specified.

            BEST_FIT_PROGRESSIVE

            AWS Batch will select additional instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types with a lower cost per unit vCPU. If additional instances of the previously selected instance types aren't available, AWS Batch will select new instance types.

            SPOT_CAPACITY_OPTIMIZED

            AWS Batch will select one or more instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

            With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch never exceeds maxvCpus by more than a single instance.

            Possible values include:
            • "BEST_FIT"
            • "BEST_FIT_PROGRESSIVE"
            • "SPOT_CAPACITY_OPTIMIZED"
          • minvCpus — (Integer)

            The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED).

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • maxvCpusrequired — (Integer)

            The maximum number of Amazon EC2 vCPUs that a compute environment can reach.

            Note: With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch will never go above maxvCpus by more than a single instance (e.g., no more than a single instance from among those specified in your compute environment).
          • desiredvCpus — (Integer)

            The desired number of Amazon EC2 vCPUS in the compute environment. AWS Batch modifies this value between the minimum and maximum values, based on job queue demand.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • instanceTypes — (Array<String>)

            The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3), or you can specify specific sizes within a family (such as c5.8xlarge). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) on the fly that match the demand of your job queues.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
            Note: When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
            Note: Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5. and R5 instance families are used.
          • imageId — (String)

            The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
            Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
          • subnetsrequired — (Array<String>)

            The VPC subnets into which the compute resources are launched. These subnets must be within the same VPC. This parameter is required for jobs running on Fargate resources, where it can contain up to 16 subnets. For more information, see VPCs and Subnets in the Amazon VPC User Guide.

          • securityGroupIds — (Array<String>)

            The Amazon EC2 security groups associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate. This parameter is required for jobs running on Fargate resources and must contain at least one security group. (Fargate does not support launch templates.) If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds will be used.

          • ec2KeyPair — (String)

            The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • instanceRole — (String)

            The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, ecsInstanceRole or arn:aws:iam::<aws_account_id>:instance-profile/ecsInstanceRole . For more information, see Amazon ECS Instance Role in the AWS Batch User Guide.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • tags — (map<String>)

            Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For AWS Batch, these take the form of "String1": "String2", where String1 is the tag key and String2 is the tag value−for example, { "Name": "AWS Batch Instance - C4OnDemand" }. This is helpful for recognizing your AWS Batch instances in the Amazon EC2 console. These tags can't be updated or removed after the compute environment has been created; any changes require creating a new compute environment and removing the old compute environment. These tags are not seen when using the AWS Batch ListTagsForResource API operation.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • placementGroup — (String)

            The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement Groups in the Amazon EC2 User Guide for Linux Instances.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • bidPercentage — (Integer)

            The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
          • spotIamFleetRole — (String)

            The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 Spot Fleet Role in the AWS Batch User Guide.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.

            To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot Instances not tagged on creation in the AWS Batch User Guide.

          • launchTemplate — (map)

            The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch Template Support in the AWS Batch User Guide.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
            • launchTemplateId — (String)

              The ID of the launch template.

            • launchTemplateName — (String)

              The name of the launch template.

            • version — (String)

              The version number of the launch template, $Latest, or $Default.

              If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

              Default: $Default.

          • ec2Configuration — (Array<map>)

            Provides information used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL1.

            Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
            • imageTyperequired — (String)

              The image type to match with the instance type to select an AMI. If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized AMI is used.

              ECS_AL2

              Amazon Linux 2− Default for all AWS Graviton-based instance families (for example, C6g, M6g, R6g, and T4g) and can be used for all non-GPU instance types.

              ECS_AL2_NVIDIA

              Amazon Linux 2 (GPU)−Default for all GPU instance families (for example P4 and G4) and can be used for all non-AWS Graviton-based instance types.

              ECS_AL1

              Amazon Linux−Default for all non-GPU, non-AWS Graviton instance families. Amazon Linux is reaching the end-of-life of standard support. For more information, see Amazon Linux AMI.

            • imageIdOverride — (String)

              The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.

        • serviceRole — (String)

          The service role associated with the compute environment that allows AWS Batch to make calls to AWS API operations on your behalf. For more information, see AWS Batch service IAM role in the AWS Batch User Guide.

      • nextToken — (String)

        The nextToken value to include in a future DescribeComputeEnvironments request. When the results of a DescribeJobDefinitions 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.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

describeJobDefinitions(params = {}, callback) ⇒ AWS.Request

Describes a list of job definitions. You can specify a status (such as ACTIVE) to only return job definitions that match that status.

Service Reference:

Examples:

To describe active job definitions


/* This example describes all of your active job definitions. */

 var params = {
  status: "ACTIVE"
 };
 batch.describeJobDefinitions(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response

 });

Calling the describeJobDefinitions operation

var params = {
  jobDefinitionName: 'STRING_VALUE',
  jobDefinitions: [
    'STRING_VALUE',
    /* more items */
  ],
  maxResults: 'NUMBER_VALUE',
  nextToken: 'STRING_VALUE',
  status: 'STRING_VALUE'
};
batch.describeJobDefinitions(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobDefinitions — (Array<String>)

      A list of up to 100 job definition names or full Amazon Resource Name (ARN) entries.

    • maxResults — (Integer)

      The maximum number of results returned by DescribeJobDefinitions in paginated output. When this parameter is used, DescribeJobDefinitions 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 DescribeJobDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeJobDefinitions returns up to 100 results and a nextToken value if applicable.

    • jobDefinitionName — (String)

      The name of the job definition to describe.

    • status — (String)

      The status used to filter job definitions.

    • nextToken — (String)

      The nextToken value returned from a previous paginated DescribeJobDefinitions 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 value is null when there are no more results to return.

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

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

          The retry strategy to use for failed jobs that are submitted with this job definition.

          • attempts — (Integer)

            The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.

          • evaluateOnExit — (Array<map>)

            Array of up to 5 objects that specify conditions under which the job should be retried or failed. If this parameter is specified, then the attempts parameter must also be specified.

The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs). and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

            • onReason — (String)

              Contains a glob pattern to match against the Reason returned for a job. The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs), and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

            • onExitCode — (String)

              Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The patten can be up to 512 characters long, can contain only numbers, and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

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.

            Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
            • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

            • 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).

          • vcpus — (Integer)

            This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. The number of vCPUs reserved for the container. Jobs running on EC2 resources can specify the vCPU requirement for the job using resourceRequirements but the vCPU requirements can't be specified both here and in the resourceRequirement structure. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified in several places. It must be specified for each node at least once.

            Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.
          • memory — (Integer)

            This parameter is deprecated and not supported for jobs run on Fargate resources, use ResourceRequirement. For jobs run on EC2 resources can specify the memory requirement using the ResourceRequirement structure. The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places; it must be specified for each node at least once.

            Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.
          • command — (Array<String>)

            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.

          • jobRoleArn — (String)

            The Amazon Resource Name (ARN) of the IAM role that the container can assume for AWS permissions. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

          • executionRoleArn — (String)

            The Amazon Resource Name (ARN) of the execution role that AWS Batch can assume. Jobs running on Fargate resources must provide an execution role. For more information, see AWS Batch execution IAM role in the AWS Batch User Guide.

          • volumes — (Array<map>)

            A list of data volumes used in a job.

            • host — (map)

              The contents of the host parameter determine whether your data volume persists on the host container instance and where it is 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 associated with it stop running.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • sourcePath — (String)

                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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location does not 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.

                Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • name — (String)

              The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

          • environment — (Array<map>)

            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 using plaintext environment variables for sensitive information, such as credential data.

            Note: Environment variables must not start with AWS_BATCH; this naming convention is reserved for variables that are set by the AWS Batch service.
            • name — (String)

              The name of the key-value pair. For environment variables, this is the name of the environment variable.

            • value — (String)

              The value of the key-value pair. For environment variables, this is the value of the environment variable.

            • readOnly — (Boolean)

              If this value is true, the container has read-only access to the volume. Otherwise, the container can write to the volume. The default value is false.

            • sourceVolume — (String)

              The name of the volume to mount.

          • readonlyRootFilesystem — (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.

          • privileged — (Boolean)

            When this parameter is true, the container is given elevated permissions 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. The default value is false.

              type="GPU"

              The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

              Note: GPUs are not available for jobs running on Fargate resources.
              type="MEMORY"

              For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

              Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

              For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

              VCPU = 4

              type="VCPU"

              The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

              For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

              value = 0.25

            • devices — (Array<map>)

              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.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • hostPathrequired — (String)

                The path for the device on the host container instance.

              • containerPath — (String)

              • permissions — (Array<String>)

                The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

            • initProcessEnabled — (Boolean)

              If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            • sharedMemorySize — (Integer)

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

              • mountOptions — (Array<String>)

                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"

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

              If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • swappiness — (Integer)

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

              Consider the following when you use a per-container swap configuration.

              • Swap space must be enabled and allocated on the container instance for the containers to use.

                Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
              • The swap space parameters are only supported for job definitions using EC2 resources.

              • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
          • logConfiguration — (map)

            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 might 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 on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

            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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            Note: 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.
            • logDriverrequired — (String)

              The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

              The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

              Note: Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
              awslogs

              Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

              fluentd

              Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.

              Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

              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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            • assignPublicIp — (String)

              Indicates whether the job should have a public IP address. For a job running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, in order to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking. The default value is "DISABLED".

              Possible values include:
              • "ENABLED"
              • "DISABLED"
          • fargatePlatformConfiguration — (map)

            The platform configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.

If the starting range value is omitted (:n), then 0 is used to start the range. If the ending range value is omitted (n:), then the highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (0:n). You can nest node ranges, for example 0:10 and 4:5, in which case the 4:5 range properties override the 0:10 properties.

            • container — (map)

              The container details for the node range.

              • image — (String)

                The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . 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.

                Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
                • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

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

                This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. The number of vCPUs reserved for the container. Jobs running on EC2 resources can specify the vCPU requirement for the job using resourceRequirements but the vCPU requirements can't be specified both here and in the resourceRequirement structure. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified in several places. It must be specified for each node at least once.

                Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.
              • memory — (Integer)

                This parameter is deprecated and not supported for jobs run on Fargate resources, use ResourceRequirement. For jobs run on EC2 resources can specify the memory requirement using the ResourceRequirement structure. The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places; it must be specified for each node at least once.

                Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.
              • command — (Array<String>)

                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.

              • jobRoleArn — (String)

              • executionRoleArn — (String)

                The Amazon Resource Name (ARN) of the execution role that AWS Batch can assume. Jobs running on Fargate resources must provide an execution role. For more information, see AWS Batch execution IAM role in the AWS Batch User Guide.

              • volumes — (Array<map>)

                A list of data volumes used in a job.

                • host — (map)

                  The contents of the host parameter determine whether your data volume persists on the host container instance and where it is 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 associated with it stop running.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • sourcePath — (String)

                    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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location does not 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.

                    Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                • name — (String)

                  The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

              • environment — (Array<map>)

                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 using plaintext environment variables for sensitive information, such as credential data.

                Note: Environment variables must not start with AWS_BATCH; this naming convention is reserved for variables that are set by the AWS Batch service.
                • name — (String)

                  The name of the key-value pair. For environment variables, this is the name of the environment variable.

                • value — (String)

                  The value of the key-value pair. For environment variables, this is the value of the environment variable.

              • mountPoints — (Array<map>)

                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.

                • containerPath — (String)

                  The path on the container where the host volume is mounted.

                • readOnly — (Boolean)

                  If this value is true, the container has read-only access to the volume. Otherwise, the container can write to the volume. The default value is false.

                • sourceVolume — (String)

                  The name of the volume to mount.

              • readonlyRootFilesystem — (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.

              • privileged — (Boolean)

                When this parameter is true, the container is given elevated permissions 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. The default value is false.

                Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided, or specified as false.
              • ulimits — (Array<map>)

                A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.

              • user — (String)

                The user name 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.

              • instanceType — (String)

                The instance type to use for a multi-node parallel job. All node groups in a multi-node parallel job must use the same instance type.

                Note: This parameter isn't applicable to single-node container jobs or for jobs running on Fargate resources and shouldn't be provided.
              • resourceRequirements — (Array<map>)

                The type and amount of resources to assign to a container. The supported resources include GPU, MEMORY, and VCPU.

                • valuerequired — (String)

                  The quantity of the specified resource to reserve for the container. The values vary based on the type specified.

                  type="GPU"

                  The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

                  Note: GPUs are not available for jobs running on Fargate resources.
                  type="MEMORY"

                  For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

                  Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

                  For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

                  value = 512

                  VCPU = 0.25

                  VCPU = 1, 2, or 4

                  value = 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384

                  VCPU = 2 or 4

                  value = 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720

                  VCPU = 4

                  type="VCPU"

                  The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

                  For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

                  value = 0.25

                  MEMORY = 512, 1024, or 2048

                  value = 0.5

                  MEMORY = 1024, 2048, 3072, or 4096

                  • "VCPU"
                  • "MEMORY"
              • linuxParameters — (map)

                Linux-specific modifications that are applied to the container, such as details for device mappings.

                • devices — (Array<map>)

                  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.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • hostPathrequired — (String)

                    The path for the device on the host container instance.

                  • containerPath — (String)

                    The path inside the container used to expose the host device. By default the hostPath value is used.

                  • permissions — (Array<String>)

                    The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

                • initProcessEnabled — (Boolean)

                  If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

                • sharedMemorySize — (Integer)

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

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                • tmpfs — (Array<map>)

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

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • containerPathrequired — (String)

                  • sizerequired — (Integer)

                    The size (in MiB) of the tmpfs volume.

                  • mountOptions — (Array<String>)

                    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"

                • maxSwap — (Integer)

                  The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

                  If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                • swappiness — (Integer)

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

                  Consider the following when you use a per-container swap configuration.

                  • Swap space must be enabled and allocated on the container instance for the containers to use.

                    Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
                  • The swap space parameters are only supported for job definitions using EC2 resources.

                  • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • logConfiguration — (map)

                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 might 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 on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

                Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

                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 into your container instance and run the following command: sudo docker version | grep "Server API version"

                Note: 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.
                • logDriverrequired — (String)

                  The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

                  The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

                  Note: Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
                  awslogs

                  Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

                  fluentd

                  Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.

                  gelf

                  Specifies the Graylog Extended Format (GELF) logging driver. For more information, including usage and options, see Graylog Extended Format logging driver in the Docker documentation.

                  journald

                  Specifies the journald logging driver. For more information, including usage and options, see Journald logging driver in the Docker documentation.

                  json-file

                  Specifies the JSON file logging driver. For more information, including usage and options, see JSON File logging driver in the Docker documentation.

                  splunk

                  Specifies the Splunk logging driver. For more information, including usage and options, see Splunk logging driver in the Docker documentation.

                  syslog

                  Specifies the syslog logging driver. For more information, including usage and options, see Syslog logging driver in the Docker documentation.

                  Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

                  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 into your container instance and run the following command: sudo docker version | grep "Server API version"

                  Note: If the AWS Systems Manager Parameter Store parameter exists in the same Region as the job you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
              • networkConfiguration — (map)

                The network configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.

                • assignPublicIp — (String)

                  Indicates whether the job should have a public IP address. For a job running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, in order to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking. The default value is "DISABLED".

                  Possible values include:
                  • "ENABLED"
                  • "DISABLED"
              • fargatePlatformConfiguration — (map)

                • platformVersion — (String)

                  The AWS Fargate platform version on which the jobs are running. A platform version is specified only for jobs running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This will use a recent, approved version of the AWS Fargate platform for compute resources. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

        • tags — (map<String>)

          The tags applied to the job definition.

        • propagateTags — (Boolean)

          Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.

        • platformCapabilities — (Array<String>)

          The platform capabilities required by the job definition. If no value is specified, it defaults to EC2. Jobs run on Fargate resources specify FARGATE.

      • nextToken — (String)

        The nextToken value to include in a future DescribeJobDefinitions request. When the results of a DescribeJobDefinitions 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.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

Examples:

To describe a job queue


/* This example describes the HighPriority job queue. */

 var params = {
  jobQueues: [
     "HighPriority"
  ]
 };
 batch.describeJobQueues(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    jobQueues: [
       {
      computeEnvironmentOrder: [
         {
        computeEnvironment: "arn:aws:batch:us-east-1:012345678910:compute-environment/C4OnDemand", 
        order: 1
       }
      ], 
      jobQueueArn: "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority", 
      jobQueueName: "HighPriority", 
      priority: 1, 
      state: "ENABLED", 
      status: "VALID", 
      statusReason: "JobQueue Healthy"
     }
    ]
   }
   */
 });

Calling the describeJobQueues operation

var params = {
  jobQueues: [
    'STRING_VALUE',
    /* more items */
  ],
  maxResults: 'NUMBER_VALUE',
  nextToken: 'STRING_VALUE'
};
batch.describeJobQueues(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobQueues — (Array<String>)

      A list of up to 100 queue names or full queue Amazon Resource Name (ARN) entries.

    • maxResults — (Integer)

      The maximum number of results returned by DescribeJobQueues in paginated output. When this parameter is used, DescribeJobQueues 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 DescribeJobQueues request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeJobQueues returns up to 100 results and a nextToken value if applicable.

    • nextToken — (String)

      The nextToken value returned from a previous paginated DescribeJobQueues 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 value is null when there are no more results to return.

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

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

          Possible values include:
          • "ENABLED"
          • "DISABLED"
        • status — (String)

        • priorityrequired — (Integer)

          The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order, for example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments cannot be mixed.

              type="GPU"

              The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

              Note: GPUs are not available for jobs running on Fargate resources.
              type="MEMORY"

              For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

              Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

              For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

              VCPU = 1 or 2

              value = 8192

              VCPU = 1, 2, or 4

              value = 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384

              VCPU = 2 or 4

              value = 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720

              VCPU = 4

              type="VCPU"

              The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

              For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

              value = 0.25

              MEMORY = 512, 1024, or 2048

            • devices — (Array<map>)

              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.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • hostPathrequired — (String)

                The path for the device on the host container instance.

              • containerPath — (String)

                The path inside the container used to expose the host device. By default the hostPath value is used.

              • permissions — (Array<String>)

                The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

            • initProcessEnabled — (Boolean)

              If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            • sharedMemorySize — (Integer)

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

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • tmpfs — (Array<map>)

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

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • containerPathrequired — (String)

                The absolute file path in the container where the tmpfs volume is mounted.

              • sizerequired — (Integer)

              • mountOptions — (Array<String>)

                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"

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

              If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • swappiness — (Integer)

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

              Consider the following when you use a per-container swap configuration.

              • Swap space must be enabled and allocated on the container instance for the containers to use.

                Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
              • The swap space parameters are only supported for job definitions using EC2 resources.

              • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
          • logConfiguration — (map)

            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 might 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, alternatively, it must be configured on a different log server for remote logging options. For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers might 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            Note: 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.
            • logDriverrequired — (String)

              The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

              The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

              Note: Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
              awslogs

              Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

              fluentd

              Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.

              gelf

              syslog

              Specifies the syslog logging driver. For more information, including usage and options, see Syslog logging driver in the Docker documentation.

              Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

              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 into your container instance and run the following command: sudo docker version | grep "Server API version"

              Possible values include:
              • "json-file"

              • valueFromrequired — (String)

                The secret to expose to the container. The supported values are either the full ARN of the AWS Secrets Manager secret or the full ARN of the parameter in the AWS Systems Manager Parameter Store.

                Note: If the AWS Systems Manager Parameter Store parameter exists in the same Region as the job you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
          • secrets — (Array<map>)

            The secrets to pass to the container. For more information, see Specifying sensitive data in the AWS Batch User Guide.

          • networkConfiguration — (map)

            The network configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.

            • assignPublicIp — (String)

              Indicates whether the job should have a public IP address. For a job running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, in order to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking. The default value is "DISABLED".

              Possible values include:
              • "ENABLED"
              • "DISABLED"
          • fargatePlatformConfiguration — (map)

            The platform configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.

            • platformVersion — (String)

              The AWS Fargate platform version on which the jobs are running. A platform version is specified only for jobs running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This will use a recent, approved version of the AWS Fargate platform for compute resources. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

        • nodeDetails — (map)

          An object representing the details of a node that's associated with a multi-node parallel job.

          • nodeIndex — (Integer)

              The range of nodes, using node index values. A range of 0:3 indicates nodes with index values of 0 through 3. If the starting range value is omitted (:n), then 0 is used to start the range. If the ending range value is omitted (n:), then the highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (0:n). You can nest node ranges, for example 0:10 and 4:5, in which case the 4:5 range properties override the 0:10 properties.

            • container — (map)

              The container details for the node range.

              • image — (String)

                The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . 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.

                Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
                • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

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

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

              • vcpus — (Integer)

                This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. The number of vCPUs reserved for the container. Jobs running on EC2 resources can specify the vCPU requirement for the job using resourceRequirements but the vCPU requirements can't be specified both here and in the resourceRequirement structure. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified in several places. It must be specified for each node at least once.

                Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.
              • memory — (Integer)

                This parameter is deprecated and not supported for jobs run on Fargate resources, use ResourceRequirement. For jobs run on EC2 resources can specify the memory requirement using the ResourceRequirement structure. The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places; it must be specified for each node at least once.

                Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.
              • command — (Array<String>)

                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.

              • jobRoleArn — (String)

                The Amazon Resource Name (ARN) of the IAM role that the container can assume for AWS permissions. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

              • executionRoleArn — (String)

                The Amazon Resource Name (ARN) of the execution role that AWS Batch can assume. Jobs running on Fargate resources must provide an execution role. For more information, see AWS Batch execution IAM role in the AWS Batch User Guide.

              • volumes — (Array<map>)

                A list of data volumes used in a job.

                • host — (map)

                  The contents of the host parameter determine whether your data volume persists on the host container instance and where it is 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 associated with it stop running.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • sourcePath — (String)

                    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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location does not 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.

                  Note: GPUs are not available for jobs running on Fargate resources.
                  type="MEMORY"

                  For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

                  Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

                  For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

                  type="VCPU"

                  The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

                  For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

                  value = 0.25

              • linuxParameters — (map)

                Linux-specific modifications that are applied to the container, such as details for device mappings.

                • devices — (Array<map>)

                  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.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • hostPathrequired — (String)

                    The path for the device on the host container instance.

                  • containerPath — (String)

                    The path inside the container used to expose the host device. By default the hostPath value is used.

                  • permissions — (Array<String>)

                    The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

                • initProcessEnabled — (Boolean)

                  If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

                • sharedMemorySize — (Integer)

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

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                • tmpfs — (Array<map>)

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

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                  • containerPathrequired — (String)

                  • mountOptions — (Array<String>)

                    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"

                • maxSwap — (Integer)

                  The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

                  If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
                • swappiness — (Integer)

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

                  Consider the following when you use a per-container swap configuration.

                  • Swap space must be enabled and allocated on the container instance for the containers to use.

                    Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
                  • The swap space parameters are only supported for job definitions using EC2 resources.

                  • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

                  Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • logConfiguration — (map)

                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 might 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 on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

                Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

                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 into your container instance and run the following command: sudo docker version | grep "Server API version"

                Note: 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.
                • logDriverrequired — (String)

                  The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

                  The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

                  Note: Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
                  awslogs

                  Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

                  fluentd

                  Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.

                  gelf

                  Specifies the Graylog Extended Format (GELF) logging driver. For more information, including usage and options, see Graylog Extended Format logging driver in the Docker documentation.

                  journald

                  Specifies the journald logging driver. For more information, including usage and options, see Journald logging driver in the Docker documentation.

                  json-file

                  Specifies the JSON file logging driver. For more information, including usage and options, see JSON File logging driver in the Docker documentation.

                  splunk

                  Specifies the Splunk logging driver. For more information, including usage and options, see Splunk logging driver in the Docker documentation.

                  syslog

                  Specifies the syslog logging driver. For more information, including usage and options, see Syslog logging driver in the Docker documentation.

                  Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

                  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 into your container instance and run the following command: sudo docker version | grep "Server API version"

              • networkConfiguration — (map)

                The network configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.

                • assignPublicIp — (String)

                  Indicates whether the job should have a public IP address. For a job running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, in order to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking. The default value is "DISABLED".

                  Possible values include:
                  • "ENABLED"
                  • "DISABLED"

            The time duration in seconds (measured from the job attempt's startedAt timestamp) after which AWS Batch terminates your jobs if they have not finished. The minimum value for the timeout is 60 seconds.

        • tags — (map<String>)

          The tags applied to the job.

        • propagateTags — (Boolean)

          Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.

        • platformCapabilities — (Array<String>)

          The platform capabilities required by the job definition. If no value is specified, it defaults to EC2. Jobs run on Fargate resources specify FARGATE.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

listJobs(params = {}, callback) ⇒ AWS.Request

Returns a list of AWS Batch jobs.

You must specify only one of the following items:

  • A job queue ID to return a list of jobs in that job queue

  • A multi-node parallel job ID to return a list of that job's nodes

  • An array job ID to return a list of that job's children

You can filter the results by job status with the jobStatus parameter. If you don't specify a status, only RUNNING jobs are returned.

Examples:

To list running jobs


/* This example lists the running jobs in the HighPriority job queue. */

 var params = {
  jobQueue: "HighPriority"
 };
 batch.listJobs(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {

 batch.listJobs(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*

      jobName: "example"
     }
    ]
   }
   */
 });

Calling the listJobs operation

var params = {
  arrayJobId: 'STRING_VALUE',
  jobQueue: 'STRING_VALUE',
  jobStatus: SUBMITTED | PENDING | RUNNABLE | STARTING | RUNNING | SUCCEEDED | FAILED,
  maxResults: 'NUMBER_VALUE',
  multiNodeJobId: 'STRING_VALUE',
  nextToken: 'STRING_VALUE'
};
batch.listJobs(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobQueue — (String)

      The name or full Amazon Resource Name (ARN) of the job queue used to list jobs.

    • arrayJobId — (String)

      The job ID for an array job. Specifying an array job ID with this parameter lists all child jobs from within the specified array.

    • multiNodeJobId — (String)

      The job ID for a multi-node parallel job. Specifying a multi-node parallel job ID with this parameter lists all nodes that are associated with the specified job.

    • jobStatus — (String)

      The job status used to filter jobs in the specified queue. If you don't specify a status, only RUNNING jobs are returned.

      Possible values include:
      • "SUBMITTED"
      • "PENDING"
      • "RUNNABLE"
      • "STARTING"
      • "RUNNING"
      • "SUCCEEDED"
      • "FAILED"
    • maxResults — (Integer)

      The maximum number of results returned by ListJobs in paginated output. When this parameter is used, ListJobs 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 ListJobs request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListJobs returns up to 100 results and a nextToken value if applicable.

    • nextToken — (String)

      The nextToken value returned from a previous paginated ListJobs 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 value is null when there are no more results to return.

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

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • jobSummaryList — (Array<map>)

          The name of the job.

        • createdAt — (Integer)

          The Unix timestamp for when the job was created. For non-array jobs and parent array jobs, this is when the job entered the SUBMITTED state (at the time SubmitJob was called). For array child jobs, this is when the child job was spawned by its parent and entered the PENDING state.

        • status — (String)

          The current status for the job.

          Possible values include:
          • "SUBMITTED"

          • reason — (String)

            A short (255 max characters) human-readable string to provide additional details about a running or stopped container.

        • arrayProperties — (map)

          The array properties of the job, if it is an array job.

          • size — (Integer)

            The size of the array job. This parameter is returned for parent array jobs.

          • index — (Integer)

      • nextToken — (String)

        The nextToken value to include in a future ListJobs request. When the results of a ListJobs 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.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

listTagsForResource(params = {}, callback) ⇒ AWS.Request

      The name of the job definition to register. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

    • type — (String)

      The type of job definition. For more information about multi-node parallel jobs, see Creating a multi-node parallel job definition in the AWS Batch User Guide.

      Note: If the job is run on Fargate resources, then multinode isn't supported.
      Possible values include:
      • "container"
      • "multinode"
    • parameters — (map<String>)

      Default parameter substitution placeholders to set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.

    • containerProperties — (map)

      An object with various properties specific to single-node container-based jobs. If the job definition's type parameter is container, then you must specify either containerProperties or nodeProperties.

      Note: If the job runs on Fargate resources, then you must not specify nodeProperties; use only containerProperties.
      • image — (String)

        The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . 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.

        Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
        • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

        • 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).

      • vcpus — (Integer)

        This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. The number of vCPUs reserved for the container. Jobs running on EC2 resources can specify the vCPU requirement for the job using resourceRequirements but the vCPU requirements can't be specified both here and in the resourceRequirement structure. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified in several places. It must be specified for each node at least once.

        Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.

          • sourcePath — (String)

            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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location does not 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.

            Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
        • name — (String)

          The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

          Note: GPUs are not available for jobs running on Fargate resources.
          type="MEMORY"

          For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

          Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

          For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

          VCPU = 2 or 4

          value = 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720

          VCPU = 4

          type="VCPU"

          The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

          For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

          • containerPath — (String)

            The path inside the container used to expose the host device. By default the hostPath value is used.

          • permissions — (Array<String>)

            The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

        • initProcessEnabled — (Boolean)

          If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

        • sharedMemorySize — (Integer)

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

          Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
        • tmpfs — (Array<map>)

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

        • maxSwap — (Integer)

          The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

          If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

          Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
        • swappiness — (Integer)

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

          Consider the following when you use a per-container swap configuration.

          • Swap space must be enabled and allocated on the container instance for the containers to use.

            Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
          • The swap space parameters are only supported for job definitions using EC2 resources.

          • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

          Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
      • logConfiguration — (map)

        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 might 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 on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

        Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

        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 into your container instance and run the following command: sudo docker version | grep "Server API version"

        Note: 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.
        • logDriverrequired — (String)

          The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

          The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

          Note: Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.

          syslog

          Specifies the syslog logging driver. For more information, including usage and options, see Syslog logging driver in the Docker documentation.

          Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

          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 into your container instance and run the following command: sudo docker version | grep "Server API version"

If one isn't specified, the LATEST platform version is used by default. This will use a recent, approved version of the AWS Fargate platform for compute resources. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

    • nodeProperties — (map)

      An object with various properties specific to multi-node parallel jobs. If you specify node properties for a job, it becomes a multi-node parallel job. For more information, see Multi-node Parallel Jobs in the AWS Batch User Guide. If the job definition's type parameter is container, then you must specify either containerProperties or nodeProperties.

      Note: If the job runs on Fargate resources, then you must not specify nodeProperties; use containerProperties instead.

        A list of node ranges and their properties associated with a multi-node parallel job.

        • targetNodesrequired — (String)

          The range of nodes, using node index values. A range of 0:3 indicates nodes with index values of 0 through 3. If the starting range value is omitted (:n), then 0 is used to start the range. If the ending range value is omitted (n:), then the highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (0:n). You can nest node ranges, for example 0:10 and 4:5, in which case the 4:5 range properties override the 0:10 properties.

        • container — (map)

          The container details for the node range.

          • image — (String)

            The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . 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.

            Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
            • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

            • 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).

          • vcpus — (Integer)

            This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. The number of vCPUs reserved for the container. Jobs running on EC2 resources can specify the vCPU requirement for the job using resourceRequirements but the vCPU requirements can't be specified both here and in the resourceRequirement structure. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified in several places. It must be specified for each node at least once.

            Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.
          • memory — (Integer)

            This parameter is deprecated and not supported for jobs run on Fargate resources, use ResourceRequirement. For jobs run on EC2 resources can specify the memory requirement using the ResourceRequirement structure. The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places; it must be specified for each node at least once.

            Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

          • volumes — (Array<map>)

            A list of data volumes used in a job.

            • host — (map)

              The contents of the host parameter determine whether your data volume persists on the host container instance and where it is 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 associated with it stop running.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
              • sourcePath — (String)

                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 this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location does not 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.

                Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • name — (String)

              The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints.

              type="GPU"

              The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

              Note: GPUs are not available for jobs running on Fargate resources.
              type="MEMORY"

              For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

              Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

              For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

              • permissions — (Array<String>)

                The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

            • initProcessEnabled — (Boolean)

              If true, 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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            • sharedMemorySize — (Integer)

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

            • maxSwap — (Integer)

              The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

              If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't 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.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
            • swappiness — (Integer)

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

              Consider the following when you use a per-container swap configuration.

              • Swap space must be enabled and allocated on the container instance for the containers to use.

                Note: The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
              • The swap space parameters are only supported for job definitions using EC2 resources.

              • If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60 and the total swap usage will be limited to two times the memory reservation of the container.

              Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
          • logConfiguration — (map)

            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 might 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 on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

            Note: AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

            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 into your container instance and run the following command: sudo docker version | grep "Server API version"

            Note: 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.
            • logDriverrequired — (String)

              The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

              Note: If you have a custom driver that'sn't listed earlier that you want to work with the Amazon ECS container agent, 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 want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

              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 into your container instance and run the following command: sudo docker version | grep "Server API version"

              The AWS Fargate platform version on which the jobs are running. A platform version is specified only for jobs running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This will use a recent, approved version of the AWS Fargate platform for compute resources. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

    • retryStrategy — (map)

      The retry strategy to use for failed jobs that are submitted with this job definition. Any retry strategy that's specified during a SubmitJob operation overrides the retry strategy defined here. If a job is terminated due to a timeout, it isn't retried.

      • attempts — (Integer)

        The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.

      • evaluateOnExit — (Array<map>)

        Array of up to 5 objects that specify conditions under which the job should be retried or failed. If this parameter is specified, then the attempts parameter must also be specified.

        • onStatusReason — (String)

          Contains a glob pattern to match against the StatusReason returned for a job. The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs). and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • onReason — (String)

          Contains a glob pattern to match against the Reason returned for a job. The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs), and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • onExitCode — (String)

          Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The patten can be up to 512 characters long, can contain only numbers, and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • actionrequired — (String)

          Specifies the action to take if all of the specified conditions (onStatusReason, onReason, and onExitCode) are met. The values are not case sensitive.

          Possible values include:
          • "RETRY"
          • "EXIT"
    • propagateTags — (Boolean)

      Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.

    • timeout — (map)

      The timeout configuration for jobs that are submitted with this job definition, after which AWS Batch terminates your jobs if they have not finished. If a job is terminated due to a timeout, it isn't retried. The minimum value for the timeout is 60 seconds. Any timeout configuration that's specified during a SubmitJob operation overrides the timeout configuration defined here. For more information, see Job Timeouts in the AWS Batch User Guide.

      • attemptDurationSeconds — (Integer)

        The time duration in seconds (measured from the job attempt's startedAt timestamp) after which AWS Batch terminates your jobs if they have not finished. The minimum value for the timeout is 60 seconds.

    • tags — (map<String>)

      The tags that you apply to the job definition to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging AWS Resources in AWS Batch User Guide.

    • platformCapabilities — (Array<String>)

      The platform capabilities required by the job definition. If no value is specified, it defaults to EC2. To run the job on Fargate resources, specify FARGATE.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • jobDefinitionArn — (String)

        The Amazon Resource Name (ARN) of the job definition.

      • revision — (Integer)

        The revision of the job definition.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

submitJob(params = {}, callback) ⇒ AWS.Request

Submits an AWS Batch job from a job definition. Parameters specified during SubmitJob override parameters defined in the job definition.

Jobs run on Fargate resources don't run for more than 14 days. After 14 days, the Fargate resources might no longer be available and the job is terminated.

Parameters:

  • params (Object) (defaults to: {})
    • jobName — (String)

      The name of the job. The first character must be alphanumeric, and up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

    • jobQueue — (String)

      The job queue into which the job is submitted. You can specify either the name or the Amazon Resource Name (ARN) of the queue.

    • arrayProperties — (map)

      The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. For more information, see Array Jobs in the AWS Batch User Guide.

      • size — (Integer)

        The size of the array job.

    • dependsOn — (Array<map>)

      A list of dependencies for the job. A job can depend upon a maximum of 20 jobs. You can specify a SEQUENTIAL type dependency without specifying a job ID for array jobs so that each child array job completes sequentially, starting at index 0. You can also specify an N_TO_N type dependency with a job ID for array jobs. In that case, each index child of this job must wait for the corresponding index child of each dependency to complete before it can begin.

      • jobId — (String)

        The job ID of the AWS Batch job associated with this dependency.

      • type — (String)

        The type of the job dependency.

        Possible values include:
        • "N_TO_N"
        • "SEQUENTIAL"
    • jobDefinition — (String)

      The job definition used by this job. This value can be one of name, name:revision, or the Amazon Resource Name (ARN) for the job definition. If name is specified without a revision then the latest active revision is used.

    • parameters — (map<String>)

      Additional parameters passed to the job that replace parameter substitution placeholders that are set in the job definition. Parameters are specified as a key and value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.

    • containerOverrides — (map)

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

      • vcpus — (Integer)

        This parameter is deprecated and not supported for jobs run on Fargate resources, see resourceRequirement. For jobs run on EC2 resources, the number of vCPUs to reserve for the container. This value overrides the value set in the job definition. Jobs run on EC2 resources can specify the vCPU requirement using resourceRequirement but the vCPU requirements can't be specified both here and in resourceRequirement. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU.

        Note: This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. Jobs running on Fargate resources must specify the vCPU requirement for the job using resourceRequirements.
      • memory — (Integer)

        This parameter is deprecated and not supported for jobs run on Fargate resources, use ResourceRequirement. For jobs run on EC2 resource, the number of MiB of memory reserved for the job. This value overrides the value set in the job definition.

      • command — (Array<String>)

        The command to send to the container that overrides the default command from the Docker image or the job definition.

      • instanceType — (String)

        The instance type to use for a multi-node parallel job.

        Note: This parameter isn't applicable to single-node container jobs or for jobs running on Fargate resources and shouldn't be provided.
      • environment — (Array<map>)

        The environment variables to send to the container. You can add new environment variables, which are added to the container at launch, or you can override the existing environment variables from the Docker image or the job definition.

        Note: Environment variables must not start with AWS_BATCH; this naming convention is reserved for variables that are set by the AWS Batch service.
        • name — (String)

          The name of the key-value pair. For environment variables, this is the name of the environment variable.

        • value — (String)

          The value of the key-value pair. For environment variables, this is the value of the environment variable.

      • resourceRequirements — (Array<map>)

        The type and amount of resources to assign to a container. This overrides the settings in the job definition. The supported resources include GPU, MEMORY, and VCPU.

        • valuerequired — (String)

          The quantity of the specified resource to reserve for the container. The values vary based on the type specified.

          type="GPU"

          The number of physical GPUs to reserve for the container. The number of GPUs reserved for all containers in a job shouldn't exceed the number of available GPUs on the compute resource that the job is launched on.

          Note: GPUs are not available for jobs running on Fargate resources.
          type="MEMORY"

          For jobs running on EC2 resources, the hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

          Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

          For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

              Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide.

              For jobs running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

              value = 512

              VCPU = 0.25

              value = 1024

              VCPU = 0.25 or 0.5

              value = 2048

              VCPU = 4

              type="VCPU"

              The number of vCPUs 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. Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

              For jobs running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

              value = 0.25

              MEMORY = 512, 1024, or 2048

              value = 0.5

              MEMORY = 1024, 2048, 3072, or 4096

              value = 1

              MEMORY = 2048, 3072, 4096, 5120, 6144, 7168, or 8192

              value = 2

              MEMORY = 4096, 5120, 6144, 7168, 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384

              value = 4

              MEMORY = 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, 16384, 17408, 18432, 19456, 20480, 21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720

            • typerequired — (String)

              The type of resource to assign to a container. The supported resources include GPU, MEMORY, and VCPU.

              Possible values include:
              • "GPU"
              • "VCPU"
              • "MEMORY"
    • retryStrategy — (map)

      The retry strategy to use for failed jobs from this SubmitJob operation. When a retry strategy is specified here, it overrides the retry strategy defined in the job definition.

      • attempts — (Integer)

        The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.

      • evaluateOnExit — (Array<map>)

        Array of up to 5 objects that specify conditions under which the job should be retried or failed. If this parameter is specified, then the attempts parameter must also be specified.

        • onStatusReason — (String)

          Contains a glob pattern to match against the StatusReason returned for a job. The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs). and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • onReason — (String)

          Contains a glob pattern to match against the Reason returned for a job. The patten can be up to 512 characters long, can contain letters, numbers, periods (.), colons (:), and white space (spaces, tabs), and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • onExitCode — (String)

          Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The patten can be up to 512 characters long, can contain only numbers, and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

        • actionrequired — (String)

          Specifies the action to take if all of the specified conditions (onStatusReason, onReason, and onExitCode) are met. The values are not case sensitive.

          Possible values include:
          • "RETRY"
          • "EXIT"
    • propagateTags — (Boolean)

      Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state. When specified, this overrides the tag propagation setting in the job definition.

    • timeout — (map)

      The timeout configuration for this SubmitJob operation. You can specify a timeout duration after which AWS Batch terminates your jobs if they haven't finished. If a job is terminated due to a timeout, it isn't retried. The minimum value for the timeout is 60 seconds. This configuration overrides any timeout configuration specified in the job definition. For array jobs, child jobs have the same timeout configuration as the parent job. For more information, see Job Timeouts in the Amazon Elastic Container Service Developer Guide.

      • attemptDurationSeconds — (Integer)

        The time duration in seconds (measured from the job attempt's startedAt timestamp) after which AWS Batch terminates your jobs if they have not finished. The minimum value for the timeout is 60 seconds.

    • tags — (map<String>)

      The tags that you apply to the job request to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging AWS Resources in AWS General Reference.

  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • computeEnvironment — (String)

      The name or full Amazon Resource Name (ARN) of the compute environment to update.

    • state — (String)

      The state of the compute environment. Compute environments in the ENABLED state can accept jobs from a queue and scale in or out automatically based on the workload demand of its associated queues.

      If the state is ENABLED, then the AWS Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

      If the state is DISABLED, then the AWS Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.

      Possible values include:
      • "ENABLED"
      • "DISABLED"
    • computeResources — (map)

      Details of the compute resources managed by the compute environment. Required for a managed compute environment. For more information, see Compute Environments in the AWS Batch User Guide.

      • minvCpus — (Integer)

        The minimum number of Amazon EC2 vCPUs that an environment should maintain.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • maxvCpus — (Integer)

        The maximum number of Amazon EC2 vCPUs that an environment can reach.

        Note: With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch will never go above maxvCpus by more than a single instance (e.g., no more than a single instance from among those specified in your compute environment).
      • desiredvCpus — (Integer)

        The desired number of Amazon EC2 vCPUS in the compute environment.

        Note: This parameter isn't applicable to jobs running on Fargate resources, and shouldn't be specified.
      • subnets — (Array<String>)

        The VPC subnets that the compute resources are launched into. This parameter is required for jobs running on Fargate compute resources, where it can contain up to 16 subnets. For more information, see VPCs and Subnets in the Amazon VPC User Guide. This can't be specified for EC2 compute resources. Providing an empty list will be handled as if this parameter wasn't specified and no change is made.

      • securityGroupIds — (Array<String>)

        The Amazon EC2 security groups associated with instances launched in the compute environment. This parameter is required for Fargate compute resources, where it can contain up to 5 security groups. This can't be specified for EC2 compute resources. Providing an empty list is handled as if this parameter wasn't specified and no change is made.

    • serviceRole — (String)

      The full Amazon Resource Name (ARN) of the IAM role that allows AWS Batch to make calls to other AWS services on your behalf. For more information, see AWS Batch service IAM role in the AWS Batch User 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.

      Note: Depending on how you created your AWS Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, AWS Batch assumes that your ARN does not use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • computeEnvironmentName — (String)

        The name of the compute environment. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

      • computeEnvironmentArn — (String)

        The Amazon Resource Name (ARN) of the compute environment.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

updateJobQueue(params = {}, callback) ⇒ AWS.Request

Service Reference:

Examples:

To update a job queue


/* This example disables a job queue so that it can be deleted. */

 var params = {
  jobQueue: "GPGPU", 
  state: "DISABLED"
 };
 batch.updateJobQueue(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    jobQueueArn: "arn:aws:batch:us-east-1:012345678910:job-queue/GPGPU", 
    jobQueueName: "GPGPU"
   }
   */
 });

Calling the updateJobQueue operation

var params = {
  jobQueue: 'STRING_VALUE', /* required */
  computeEnvironmentOrder: [
    {
      computeEnvironment: 'STRING_VALUE', /* required */
      order: 'NUMBER_VALUE' /* required */
    },
    /* more items */
  ],
  priority: 'NUMBER_VALUE',
  state: ENABLED | DISABLED
};
batch.updateJobQueue(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • jobQueue — (String)

      The name or the Amazon Resource Name (ARN) of the job queue.

    • state — (String)

      Describes the queue's ability to accept new jobs. If the job queue state is ENABLED, it is able to accept jobs. If the job queue state is DISABLED, new jobs cannot be added to the queue, but jobs already in the queue can finish.

      Possible values include:
      • "ENABLED"
      • "DISABLED"
    • priority — (Integer)

      The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order, for example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments cannot be mixed.

    • computeEnvironmentOrder — (Array<map>)

      Details the set of compute environments mapped to a job queue and their order relative to each other. This is one of the parameters used by the job scheduler to determine which compute environment should run a given job. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

      Note: All compute environments that are associated with a job queue must share the same architecture. AWS Batch doesn't support mixing compute environment architecture types in a single job queue.
      • orderrequired — (Integer)

        The order of the compute environment. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first.

      • computeEnvironmentrequired — (String)

        The Amazon Resource Name (ARN) of the compute environment.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.
