Parameters

Parameter Choices/Defaults Comments
arn
string
The ARN of the task description to delete.
aws_access_key
string
AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used.
If profile is set this parameter is ignored.
Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_access_key, access_key
aws_ca_bundle
path
The location of a CA Bundle to use when validating SSL certificates.
Only used for boto3 based modules.
Note: The CA Bundle is read 'module' side and may need to be explicitly copied from the controller if not run locally.
aws_config
dictionary
A dictionary to modify the botocore configuration.
Only the 'user_agent' key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.
aws_secret_key
string
AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used.
If profile is set this parameter is ignored.
Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_secret_key, secret_key
containers
list / elements=string
A list of containers definitions.
cpu
string
The number of cpu units used by the task. If using the EC2 launch type, this field is optional and any value can be used.
If using the Fargate launch type, this field is required and you must use one of 256, 512, 1024, 2048, 4096.
debug_botocore_endpoint_logs
boolean
    Choices:
  • no ←
  • yes
Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
ec2_url
string
Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.

aliases: aws_endpoint_url, endpoint_url
execution_role_arn
string
The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.
family
string
A Name that would be given to the task definition.
force_create
boolean
    Choices:
  • no
  • yes
Always create new task definition.
launch_type
string
    Choices:
  • EC2
  • FARGATE
The launch type on which to run your task.
memory
string
The amount (in MiB) of memory used by the task. If using the EC2 launch type, this field is optional and any value can be used.
If using the Fargate launch type, this field is required and is limited by the cpu.
network_mode
string
    Choices:
  • default
  • bridge ←
  • host
  • none
  • awsvpc
The Docker networking mode to use for the containers in the task.
awsvpc mode was added in Ansible 2.5
Windows containers must use network_mode=default, which will utilize docker NAT networking.
Setting network_mode=default for a Linux container will use bridge mode.
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated.
aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.

aliases: aws_profile
region
string
The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region

aliases: aws_region, ec2_region
revision
integer
A revision number for the task definition.
security_token
string
AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.
If profile is set this parameter is ignored.
Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: aws_security_token, access_token
state
string / required
    Choices:
  • present
  • absent
State whether the task definition should exist or be deleted.
task_role_arn
string
The Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.
validate_certs
boolean
    Choices:
  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
volumes
list / elements=dictionary
A list of names of volumes to be attached.
name
string / required
The name of the volume.

Notes

Note

  • If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_PROFILE or AWS_DEFAULT_PROFILE, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION, AWS_CA_BUNDLE

  • Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html

  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
