--- | --- | ---
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. aliases: ec2_access_key, access_key

debug_botocore_endpoint_logs
boolean
added in 2.8

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.

delay - | Default: 10 | The time to wait before checking that the service is available
deployment_configuration - |  | Optional parameters that control the deployment_configuration; format is '{"maximum_percent":<integer>, "minimum_healthy_percent":<integer>}
desired_count - |  | The count of how many instances of the service. This parameter is required when state=present
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.

state
- / required

Choices:

validate_certs
boolean

Choices:
- no

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

## Notes

Note

- the service role specified must be assumable (i.e. have a trust relationship for the ecs service, ecs.amazonaws.com)
- for details of the parameters and returns see https://boto3.readthedocs.io/en/latest/reference/services/ecs.html
- An IAM role must have been previously created
- 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_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`
- 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

|  | field string | always | The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host, which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are CPU and MEMORY.
|  | type string | always | The type of placement strategy. Valid values are random, spread and binpack.
| runningCount integer | always | The number of tasks in the cluster that are in the RUNNING state.
| serviceArn string | always | The Amazon Resource Name (ARN) that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the region of the service, the AWS account ID of the service owner, the service namespace, and then the service name.
