Client

class Batch.Client

A low-level client representing AWS Batch:

import boto3

client = boto3.client('batch')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
cancel_job(**kwargs)

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

Request Syntax

response = client.cancel_job(
    jobId='string',
    reason='string'
)
Parameters
  • jobId (string) --

    [REQUIRED]

    A list of up to 100 job IDs to cancel.

  • reason (string) --

    [REQUIRED]

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

response = client.cancel_job(
    jobId='1d828f65-7a4d-42e8-996d-3b900ed59dc4',
    reason='Cancelling job.',
)

print(response)

}
create_compute_environment(**kwargs)

Creates an AWS Batch compute environment. You can create MANAGED or UNMANAGED compute environments.

In a managed compute environment, AWS Batch manages the compute resources within the environment, based on the compute resources that you specify. Instances launched into a managed compute environment use the latest Amazon ECS-optimized AMI. You can choose to use Amazon EC2 On-Demand instances in your managed compute environment, or you can use Amazon EC2 Spot instances that only launch when the Spot bid price is below a specified percentage of the On-Demand price.

In an unmanaged compute environment, you can manage your own compute resources. This provides more compute resource configuration options, such as using a custom AMI, but you must ensure that your AMI meets the Amazon ECS container instance AMI specification. For more information, see Container Instance AMIs in the Amazon EC2 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 is associated with it and then manually launch your container instances into that Amazon ECS cluster. For more information, see Launching an Amazon ECS Container Instance in the Amazon EC2 Container Service Developer Guide .

create_job_queue(**kwargs)

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.

See also: AWS API Documentation

Request Syntax

response = client.create_job_queue(
    jobQueueName='string',
    state='ENABLED'|'DISABLED',
    priority=123,
    computeEnvironmentOrder=[
        {

  • state (string) -- The state of the job queue. If the job queue state is ENABLED , it is able to accept jobs.
  • priority (integer) --

    [REQUIRED]

    The priority of the job queue. Job queues with a higher priority (or a lower integer value for the priority parameter) are evaluated first when associated with same compute environment. Priority is determined in ascending order, for example, a job queue with a priority value of 1 is given scheduling preference over a job queue with a priority value of 10 .

  • computeEnvironmentOrder (list) --

    [REQUIRED]

    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 execute a given job. Compute environments must be in the VALID state before you can associate them with a job queue. You can associate up to 3 compute environments with a job queue.

    • (dict) --

      The order in which compute environments are tried for job placement within a queue. 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.

      • order (integer) -- [REQUIRED]

        The order of the compute environment.

      • computeEnvironment (string) -- [REQUIRED]

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

Request Syntax

response = client.describe_job_definitions(
    jobDefinitions=[
        'string',
    ],
    maxResults=123,
    jobDefinitionName='string',
    status='string',
    nextToken='string'
)
Parameters
  • jobDefinitions (list) --

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

    • (string) --
  • 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 is not 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 with which 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 is only used to retrieve the next items in a list and not for other programmatic purposes.

        • containerProperties (dict) --

          An object with various properties specific to container-based jobs.

          • 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 .

            • 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 ).

              A data volume used in a job's container properties.

              • host (dict) --

                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, but the data is not guaranteed to persist after the containers associated with it stop running.

                • sourcePath (string) --

                  The path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value 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.

              • 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 (list) --

            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 .

              • 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 privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run .

          • ulimits (list) --

            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 .

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
get_waiter(waiter_name)
list_jobs(**kwargs)

Returns a list of task jobs for a specified job queue. You can filter the results by job status with the jobStatus parameter.

Request Syntax

response = client.list_jobs(
    jobQueue='string',
    jobStatus='SUBMITTED'|'PENDING'|'RUNNABLE'|'STARTING'|'RUNNING'|'SUCCEEDED'|'FAILED',
    maxResults=123,
    nextToken='string'
)
Parameters
  • jobQueue (string) --

    [REQUIRED]

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

  • jobStatus (string) -- The job status with which to filter jobs in the specified queue.
  • 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 is not 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 is only used to retrieve the next items in a list and not for other programmatic purposes.
