Parameters

Parameter

Comments

access_key

aliases: aws_access_key_id, aws_access_key, ec2_access_key

string

AWS access key ID.

See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys.

The AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference.

Retry strategy - The number of times to move a job to the RUNNABLE status. You may specify between 1 and 10 attempts. If attempts is greater than one, the job is retried if it fails until it has moved to RUNNABLE that many times.

aws_ca_bundle

path

The location of a CA Bundle to use when validating SSL certificates.

The AWS_CA_BUNDLE environment variable may also be used.

aws_config

Describes the desired state.

Choices:

  • "present" ← (default)

  • "absent"

type

string / required

The type of job definition.

Default: []

hardLimit

string

The hard limit for the ulimit type.

name

string

The type of the ulimit.

Choices:

  • true ← (default)

vcpus

integer / required

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.

volumes

list / elements=dictionary

A list of data volumes used in a job.

Default: []

host

string

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. This is a dictionary with one property, sourcePath - 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.

Notes

Note

  • Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.

  • The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
