AWS SDK for PHP 3.x

Service ID: batch

Version: 2016-08-10

This page describes the parameters and results for the operations of the AWS Batch (2016-08-10), and shows how to use the Aws\Batch\BatchClient object to call the described operations. This documentation is specific to the 2016-08-10 API version of the service.

Operation Summary

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

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

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

DescribeComputeEnvironments
DescribeJobDefinitions
DescribeJobQueues
ListJobs
ListSchedulingPolicies

Operations

CancelJob

$result = $client->cancelJob([/* ... */]);
$promise = $client->cancelJobAsync([/* ... */]);

Cancels a job in an Batch job queue. Jobs that are in the SUBMITTED, PENDING, or RUNNABLE state are canceled. Jobs that have progressed to STARTING or RUNNING aren't canceled, but the API operation still succeeds, even if no job is canceled. These jobs must be terminated with the TerminateJob operation.

Parameter Syntax

$result = $client->cancelJob([
    'jobId' => '<string>', // REQUIRED
    'reason' => '<string>', // REQUIRED
]);

Parameter Details

Members

jobId

Required: Yes
Type: string

The Batch job ID of the job to cancel.

reason

Required: Yes
Type: 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 Batch activity logs.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ClientException:
These errors are usually caused by a client action, such as using an action or resource on behalf of a user that doesn't have permissions to use the action or resource, or specifying an identifier that's not valid.
ServerException:
These errors are usually caused by a server issue.

Examples

Example 1: To cancel a job

CreateComputeEnvironment

$result = $client->createComputeEnvironment([/* ... */]);
$promise = $client->createComputeEnvironmentAsync([/* ... */]);

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

In a managed compute environment, 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. Either, you can choose to use EC2 On-Demand Instances and EC2 Spot Instances. Or, you can 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.

Multi-node parallel jobs aren't 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 AMIs. However, you must verify that each of your AMIs meet the Amazon ECS container instance AMI specification. For more information, see container instance AMIs in the Amazon Elastic Container Service Developer Guide. After you created your unmanaged compute environment, you can use the DescribeComputeEnvironments operation to find the Amazon ECS cluster that's associated with it. Then, 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.

Batch doesn't upgrade the AMIs in a compute environment after the environment is 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 managing the guest operating system (including its 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 Batch jobs, complete these steps:

Create a new compute environment with the new AMI.
Add the compute environment to an existing job queue.
Remove the earlier compute environment from your job queue.
Delete the earlier compute environment.

]);

Parameter Details

Members

computeEnvironmentName

Required: Yes
Type: string

The name for your compute environment. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

computeResources

Type: ComputeResource structure

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 Batch User Guide.

serviceRole

Type: string

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

If your account already created the Batch service-linked role, that role is used by default for your compute environment unless you specify a different role here. If the Batch service-linked role doesn't exist in your account, and no role is specified here, the service attempts to create the Batch service-linked role in your account.

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

Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, 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.

state

Type: 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 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 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.

tags

Type: Associative array of custom strings keys (TagKey) to strings

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 Amazon Web Services Resources in Amazon Web Services 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.

type

Required: Yes
Type: string

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

unmanagedvCpus

Type: int

The maximum number of vCPUs for an unmanaged compute environment. This parameter is only used for fair share scheduling to reserve vCPU capacity for new share identifiers. If this parameter isn't provided for a fair share job queue, no vCPU capacity is reserved.

This parameter is only supported when the type parameter is set to UNMANAGED/

Result Syntax

[
    'computeEnvironmentArn' => '<string>',
    'computeEnvironmentName' => '<string>',
]

CreateJobQueue

$result = $client->createJobQueue([/* ... */]);
$promise = $client->createJobQueueAsync([/* ... */]);

Creates an 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 that the 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.

Parameter Syntax

$result = $client->createJobQueue([
    'computeEnvironmentOrder' => [ // REQUIRED
        [
            'computeEnvironment' => '<string>', // REQUIRED
            'order' => <integer>, // REQUIRED

    'priority' => <integer>, // REQUIRED
    'schedulingPolicyArn' => '<string>',
    'state' => 'ENABLED|DISABLED',
    'tags' => ['<string>', ...],
]);

Parameter Details

Members

computeEnvironmentOrder

Required: Yes
Type: Array of ComputeEnvironmentOrder structures

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.

All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

jobQueueName

Required: Yes
Type: string

The name of the job queue. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

priority

Required: Yes
Type: int

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 can't be mixed.

schedulingPolicyArn

Type: string

The Amazon Resource Name (ARN) of the fair share scheduling policy. If this parameter is specified, the job queue uses a fair share scheduling policy. If this parameter isn't specified, the job queue uses a first in, first out (FIFO) scheduling policy. After a job queue is created, you can replace but can't remove the fair share scheduling policy. The format is aws:Partition:batch:Region:Account:scheduling-policy/Name . An example is aws:aws:batch:us-west-2:012345678910:scheduling-policy/MySchedulingPolicy.

state

Type: 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.

tags

Type: Associative array of custom strings keys (TagKey) to strings

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 Batch resources in Batch User Guide.

DeleteComputeEnvironment

$result = $client->deleteComputeEnvironment([/* ... */]);
$promise = $client->deleteComputeEnvironmentAsync([/* ... */]);

Deletes an 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 Fargate resources must terminate all active jobs on that compute environment before deleting the compute environment. If this isn't done, the compute environment enters an invalid state.

[]

Result Details

The results for this operation are always empty.

Errors

ClientException:
These errors are usually caused by a client action, such as using an action or resource on behalf of a user that doesn't have permissions to use the action or resource, or specifying an identifier that's not valid.
ServerException:
These errors are usually caused by a server issue.

Examples

Example 1: To deregister a job definition

DescribeComputeEnvironments

$result = $client->describeComputeEnvironments([/* ... */]);
$promise = $client->describeComputeEnvironmentsAsync([/* ... */]);

Describes one or more of your compute environments.

If you're using an unmanaged compute environment, you can use the DescribeComputeEnvironment operation to determine the ecsClusterArn that you should launch your Amazon ECS container instances into.

Parameter Syntax

$result = $client->describeComputeEnvironments([
    'computeEnvironments' => ['<string>', ...],
    'maxResults' => <integer>,
    'nextToken' => '<string>',
]);

Parameter Details

Members

computeEnvironments

Type: Array of strings

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

maxResults

Type: int

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

Type: 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.

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.

jobDefinitions

Type: Array of JobDefinition structures

The list of job definitions.

nextToken

Type: 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.

Errors

ClientException:
These errors are usually caused by a client action, such as using an action or resource on behalf of a user that doesn't have permissions to use the action or resource, or specifying an identifier that's not valid.
ServerException:
These errors are usually caused by a server issue.

DescribeJobQueues

$result = $client->describeJobQueues([/* ... */]);
$promise = $client->describeJobQueuesAsync([/* ... */]);

Describes one or more of your job queues.

Parameter Syntax

    'jobQueues' => ['<string>', ...],
    'maxResults' => <integer>,
    'nextToken' => '<string>',
]);

Parameter Details

Members

jobQueues

Type: Array of strings

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

maxResults

Type: int

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 and 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

Type: 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.

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.

schedulingPolicies

Type: Array of SchedulingPolicyDetail structures

The list of scheduling policies.

Errors

ClientException:
These errors are usually caused by a client action, such as using an action or resource on behalf of a user that doesn't have permissions to use the action or resource, or specifying an identifier that's not valid.
ServerException:
These errors are usually caused by a server issue.

ListJobs

$result = $client->listJobs([/* ... */]);
$promise = $client->listJobsAsync([/* ... */]);

Returns a list of 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 nodes for that job
An array job ID to return a list of the children for that job

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

Parameter Syntax

$result = $client->listJobs([
    'arrayJobId' => '<string>',
    'filters' => [
        [
            'name' => '<string>',
            'values' => ['<string>', ...],
        ],
        // ...
    ],
    'jobQueue' => '<string>',
    'jobStatus' => 'SUBMITTED|PENDING|RUNNABLE|STARTING|RUNNING|SUCCEEDED|FAILED',
    'maxResults' => <integer>,
    'multiNodeJobId' => '<string>',
    'nextToken' => '<string>',
]);

Parameter Details

Members

arrayJobId

Type: 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.

filters

Type: Array of KeyValuesPair structures

The filter to apply to the query. Only one filter can be used at a time. When the filter is used, jobStatus is ignored. The filter doesn't apply to child jobs in an array or multi-node parallel (MNP) jobs. The results are sorted by the createdAt field, with the most recent jobs being first.

JOB_NAME: The value of the filter is a case-insensitive match for the job name. If the value ends with an asterisk (*), the filter will match any job name that begins with the string before the '*'. This corresponds to the jobName value. For example, test1 matches both Test1 and test1, and test1* matches both test1 and Test10. When the JOB_NAME filter is used, the results are grouped by the job name and version.
JOB_DEFINITION: The value for the filter is the name or Amazon Resource Name (ARN) of the job definition. This corresponds to the jobDefinition value. The value is case sensitive. When the value for the filter is the job definition name, the results include all the jobs that used any revision of that job definition name. If the value ends with an asterisk (*), the filter will match any job definition name that begins with the string before the '*'. For example, jd1 matches only jd1, and jd1* matches both jd1 and jd1A. The version of the job definition that's used doesn't affect the sort order. When the JOB_DEFINITION filter is used and the ARN is used (which is in the form arn:${Partition}:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision}), the results include jobs that used the specified revision of the job definition. Asterisk (*) is not supported when the ARN is used.
BEFORE_CREATED_AT: The value for the filter is the time that's before the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.
AFTER_CREATED_AT: The value for the filter is the time that's after the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.

jobQueue

Type: string

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

jobStatus

Type: string

The job status used to filter jobs in the specified queue. If the filters parameter is specified, the jobStatus parameter is ignored and jobs with any status are returned. If you don't specify a status, only RUNNING jobs are returned.

maxResults

Type: int

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 and 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.

multiNodeJobId

Type: 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.

nextToken

Type: 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.

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.

Parameter Details

Members

containerProperties

Type: ContainerProperties structure

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.

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

jobDefinitionName

Required: Yes
Type: string

The name of the job definition to register. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

nodeProperties

Type: NodeProperties structure

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 Batch User Guide. If the job definition's type parameter is container, then you must specify either containerProperties or nodeProperties.

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

parameters

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

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.

platformCapabilities

Type: Array of strings

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.

propagateTags

Type: 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.

retryStrategy

Type: RetryStrategy structure

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.

schedulingPriority

Type: int

The scheduling priority for jobs that are submitted with this job definition. This will only affect jobs in job queues with a fair share policy. Jobs with a higher scheduling priority will be scheduled before jobs with a lower scheduling priority.

The minimum supported value is 0 and the maximum supported value is 9999.

tags

Type: Associative array of custom strings keys (TagKey) to strings

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 Amazon Web Services Resources in Batch User Guide.

timeout

Type: JobTimeout structure

The timeout configuration for jobs that are submitted with this job definition, after which 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 Batch User Guide.

type

Required: Yes
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 Batch User Guide.

If the job is run on Fargate resources, then multinode isn't supported.

Examples

Example 1: To register a job definition

This example registers a job definition for a simple container job.

$result = $client->registerJobDefinition([
    'type' => 'container',
    'containerProperties' => [
        'command' => [
            'sleep',
            '10',
        ],
        'image' => 'busybox',
        'resourceRequirements' => [
            [
                'type' => 'MEMORY',
                'value' => '128',
            ],
            [
                'type' => 'VCPU',
                'value' => '1',
            ],
        ],
    ],
    'jobDefinitionName' => 'sleep10',
]);

Result syntax:

[
    'jobDefinitionArn' => 'arn:aws:batch:us-east-1:012345678910:job-definition/sleep10:1',
    'jobDefinitionName' => 'sleep10',
    'revision' => 1,
]

Example 2: RegisterJobDefinition with tags

This demonstrates calling the RegisterJobDefinition action, including tags.

$result = $client->registerJobDefinition([
    'type' => 'container',
    'containerProperties' => [
        'command' => [
            'sleep',
            '30',
        ],
        'image' => 'busybox',
        'resourceRequirements' => [
            [
                'type' => 'MEMORY',
                'value' => '128',
            ],
            [
                'type' => 'VCPU',
                'value' => '1',

    'jobDefinitionName' => 'sleep30',
    'revision' => 1,
]

SubmitJob

$result = $client->submitJob([/* ... */]);
$promise = $client->submitJobAsync([/* ... */]);

Submits an Batch job from a job definition. Parameters that are specified during SubmitJob override parameters defined in the job definition. vCPU and memory requirements that are specified in the resourceRequirements objects in the job definition are the exception. They can't be overridden this way using the memory and vcpus parameters. Rather, you must specify updates to job definition parameters in a ResourceRequirements object that's included in the containerOverrides parameter.

Job queues with a scheduling policy are limited to 500 active fair share identifiers at a time.

Jobs that run on Fargate resources can't be guaranteed to run for more than 14 days. This is because, after 14 days, Fargate resources might become unavailable and job might be terminated.

Parameter Details

Members

arrayProperties

Type: ArrayProperties structure

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 Batch User Guide.

containerOverrides

Type: ContainerOverrides structure

A list of container overrides in the JSON format that specify the name of a container in the specified job definition and the overrides it should receive.

You can also override existing environment variables on a container or add new environment variables to it with an environment override.

dependsOn

Type: Array of JobDependency structures

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.

jobDefinition

Required: Yes
Type: 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.

jobName

Required: Yes
Type: string

The name of the job. It can be up to 128 letters long. The first character must be alphanumeric, can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

jobQueue

Required: Yes
Type: string

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

nodeOverrides

Type: NodeOverrides structure

A list of node overrides in JSON format that specify the node range to target and the container overrides for that node range.

This parameter isn't applicable to jobs that are running on Fargate resources; use containerOverrides instead.

parameters

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

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.

propagateTags

Type: 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.

retryStrategy

Type: RetryStrategy structure

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.

schedulingPriorityOverride

Type: int

The scheduling priority for the job. This will only affect jobs in job queues with a fair share policy. Jobs with a higher scheduling priority will be scheduled before jobs with a lower scheduling priority. This will override any scheduling priority in the job definition.

The minimum supported value is 0 and the maximum supported value is 9999.

shareIdentifier

Type: string

The share identifier for the job.

tags

Type: Associative array of custom strings keys (TagKey) to strings

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 Amazon Web Services Resources in Amazon Web Services General Reference.

timeout

Type: JobTimeout structure

Parameter Details

Members

computeEnvironmentOrder

Type: Array of ComputeEnvironmentOrder structures

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.

All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

jobQueue

Required: Yes
Type: string

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

priority

Type: int

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 can't be mixed.

schedulingPolicyArn

Type: string

Amazon Resource Name (ARN) of the fair share scheduling policy. Once a job queue is created, the fair share scheduling policy can be replaced but not removed. The format is aws:Partition:batch:Region:Account:scheduling-policy/Name . For example, aws:aws:batch:us-west-2:012345678910:scheduling-policy/MySchedulingPolicy.

state

Type: string

Describes the queue's ability to accept new jobs. If the job queue state is ENABLED, it can 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.

ComputeResource

Description

An object representing an Batch compute resource. For more information, see Compute Environments in the Batch User Guide.

Members

allocationStrategy

Type: 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 Batch User Guide.

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

BEST_FIT (default): 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, Batch waits for the additional instances to be available. If there aren't enough instances available, or if the user is reaching Amazon EC2 service limits then additional jobs aren't run until the 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: 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, Batch will select new instance types.
SPOT_CAPACITY_OPTIMIZED: 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, Batch might need to go above maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

bidPercentage

Type: int

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.

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

desiredvCpus

Type: int

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

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

ec2Configuration

Type: Array of Ec2Configuration structures

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_AL2.

One or two values can be provided.

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

ec2KeyPair

Type: 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.

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

imageId

Type: 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.

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

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.

instanceRole

Type: 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 Batch User Guide.

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

instanceTypes

Type: Array of strings

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) that match the demand of your job queues.

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

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.

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.

launchTemplate

Type: LaunchTemplateSpecification structure

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 Batch User Guide.

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

maxvCpus

Required: Yes
Type: int

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

With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. For example, no more than a single instance from among those specified in your compute environment is allocated.

minvCpus

Type: int

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

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

placementGroup

Type: 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.

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

securityGroupIds

Type: Array of strings

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 that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds are used.

spotIamFleetRole

Type: 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 Batch User Guide.

This parameter isn't applicable to jobs that are 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 Batch User Guide.

subnets

Required: Yes
Type: Array of strings

The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and Subnets in the Amazon VPC User Guide.

tags

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

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

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

type

Required: Yes
Type: string

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

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

maxvCpus

Type: int

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

With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. That is, no more than a single instance from among those specified in your compute environment.

logConfiguration

Type: LogConfiguration structure

The log configuration specification for the container.

This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However, the container 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.

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"

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.

LinuxParameters

Description

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

Members

devices

Type: Array of Device structures

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

This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.

initProcessEnabled

Type: 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"

maxSwap

Type: int

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.

This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.

sharedMemorySize

Type: int

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

This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.

swappiness

Type: int

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.

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.

This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.

tmpfs

Type: Array of Tmpfs structures

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