computeEnvironments๐Ÿ”น

Type: OrderedComputeEnvironment[]

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 runs 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.


env๐Ÿ”น

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.


jobQueueArn๐Ÿ”น

Type: string

The ARN of this job queue.


jobQueueName๐Ÿ”น

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 (_)


node๐Ÿ”น

Type: Node

The tree node.


priority๐Ÿ”น

Type: number

The priority of the job queue.

Job queues with a higher priority 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.


stack๐Ÿ”น

Type: Stack

The stack in which this resource is defined.


enabled?๐Ÿ”น

Type: boolean (optional, default: true)

If the job queue is enabled, it is able to accept jobs.

Otherwise, new jobs can't be added to the queue, but jobs already in the queue can finish.


schedulingPolicy?๐Ÿ”น

Type: ISchedulingPolicy (optional, default: no scheduling policy)

The SchedulingPolicy for this JobQueue.

Instructs the Scheduler how to schedule different jobs.

Methods

NameDescription
addComputeEnvironment(computeEnvironment, order)๐Ÿ”นAdd a ComputeEnvironment to this Queue.
applyRemovalPolicy(policy)๐Ÿ”นApply the given removal policy to this resource.

addComputeEnvironment(computeEnvironment, order)๐Ÿ”น

public addComputeEnvironment(computeEnvironment: IComputeEnvironment, order: number): void

Parameters

  • computeEnvironment IComputeEnvironment
  • order number

Add a ComputeEnvironment to this Queue.

The Queue will prefer lower-order ComputeEnvironments.


applyRemovalPolicy(policy)๐Ÿ”น

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

  • policy RemovalPolicy

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).
