Class: Aws::Batch::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for AWS Batch. To construct a client, you need to configure a :region and :credentials.

batch = Aws::Batch::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::Batch::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

#cancel_job(options = {}) ⇒ Struct

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.

Examples:

Example: To cancel a job


# This example cancels a job with the specified job ID.

resp = client.cancel_job({
  job_id: "1d828f65-7a4d-42e8-996d-3b900ed59dc4", 
  reason: "Cancelling job.", 
})

# resp.to_h outputs the following:
{
}

Request syntax with placeholder values


resp = client.cancel_job({
  job_id: "String", # required
  reason: "String", # required
})

Options Hash (options):

  • :job_id (required, String)

    A list of up to 100 job IDs to cancel.

  • :reason (required, String)

    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.

Returns:

  • (Struct)

    Returns an empty response.

#create_compute_environment(options = {}) ⇒ Types::CreateComputeEnvironmentResponse

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 a recent, approved version of the 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.

Examples:

Example: To create a managed EC2 compute environment


# This example creates a managed compute environment with specific C4 instance types that are launched on demand. The compute environment is called C4OnDemand.

Response structure


resp.compute_environment_name #=> String
resp.compute_environment_arn #=> String

Options Hash (options):

  • :compute_environment_name (required, String)

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

  • :type (required, String)

    The type of the compute environment.

  • :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.

  • :compute_resources (Types::ComputeResource)

    Details of the compute resources managed by the compute environment. This parameter is required for managed compute environments.

  • :service_role (required, 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.

    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.

    Depending on how you created your AWS Batch service role, its ARN may 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.

Returns:

#create_job_queue(options = {}) ⇒ Types::CreateJobQueueResponse

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.

Examples:

Example: To create a job queue with a single compute environment


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

resp = client.create_job_queue({
  compute_environment_order: [
    {
      compute_environment: "M4Spot", 
      order: 1, 
    }, 
  ], 
  job_queue_name: "LowPriority", 
  priority: 1, 
  state: "ENABLED", 
})

# resp.to_h outputs the following:
{
  job_queue_arn: "arn:aws:batch:us-east-1:012345678910:job-queue/LowPriority", 
  job_queue_name: "LowPriority", 
}

Example: 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.

resp = client.create_job_queue({
  compute_environment_order: [
    {
      compute_environment: "C4OnDemand", 
      order: 1, 
    }, 
    {
      compute_environment: "M4Spot", 
      order: 2, 
    }, 
  ], 
  job_queue_name: "HighPriority", 
  priority: 10, 
  state: "ENABLED", 
})

# resp.to_h outputs the following:
{
  job_queue_arn: "arn:aws:batch:us-east-1:012345678910:job-queue/HighPriority",

    },
  ],
})

Response structure


resp.job_queue_name #=> String
resp.job_queue_arn #=> String

Options Hash (options):

  • :job_queue_name (required, String)

    The name of the job queue.

  • :state (String)

    The state of the job queue. If the job queue state is ENABLED, it is able to accept jobs.

  • :priority (required, 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 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.

  • :compute_environment_order (required, Array<Types::ComputeEnvironmentOrder>)

    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.

Returns:

See Also:

#delete_compute_environment(options = {}) ⇒ Struct

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.

Examples:

Example: To delete a compute environment


# This example deletes the P2OnDemand compute environment.

resp = client.delete_compute_environment({
  compute_environment: "P2OnDemand", 
})

# resp.to_h outputs the following:
{
}

Request syntax with placeholder values


resp = client.delete_compute_environment({
  compute_environment: "String", # required
})

Options Hash (options):

  • :compute_environment (required, String)

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

Returns:

  • (Struct)

    Returns an empty response.

See Also:

#delete_job_queue(options = {}) ⇒ Struct

Deletes the specified job queue. You must first disable submissions for a queue with the UpdateJobQueue operation. All jobs in the queue are terminated when you delete a job queue.

It is not necessary to disassociate compute environments from a queue before submitting a DeleteJobQueue request.

Examples:

Example: To delete a job queue


# This example deletes the GPGPU job queue.

resp = client.delete_job_queue({
  job_queue: "GPGPU", 
})

# resp.to_h outputs the following:

Options Hash (options):

  • :compute_environments (Array<String>)

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

  • :max_results (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 is not used, then DescribeComputeEnvironments returns up to 100 results and a nextToken value if applicable.

  • :next_token (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 is only used to retrieve the next items in a list and not for other programmatic purposes.

Returns:

Options Hash (options):

  • :job_definitions (Array<String>)

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

  • :max_results (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.

  • :job_definition_name (String)

    The name of the job definition to describe.

  • :status (String)

    The status with which to filter job definitions.

  • :next_token (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.

    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.

Response structure


resp.compute_environment_name #=> String
resp.compute_environment_arn #=> String

Options Hash (options):

  • :compute_environment (required, 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.

  • :compute_resources (Types::ComputeResourceUpdate)

    Details of the compute resources managed by the compute environment. Required for a managed compute environment.

  • :service_role (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.

    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.

    Depending on how you created your AWS Batch service role, its ARN may 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.

  • :state (String)

    Describes the queue\'s ability to accept new jobs.

  • :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 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.

  • :compute_environment_order (Array<Types::ComputeEnvironmentOrder>)

    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 execute a given job.

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(...) do |w|

  # disable max attempts

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.
