Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.

debug_botocore_endpoint_logs

boolean

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.

  • true

description

string

A description of the rule.

endpoint_url

URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS.

The AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference.

The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01.

The name of the rule you are creating, updating or deleting. No spaces or special characters allowed (i.e. must match [\.\-_A-Za-z0-9]+).

profile

aliases: aws_profile

string

A named AWS profile to use for authentication.

See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html.

The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.

region

aliases: aws_region, ec2_region

string

The AWS region to use.

For global services such as IAM, Route53 and CloudFront, region is ignored.

schedule_expression

string

A cron or rate expression that defines the schedule the rule will trigger on. For example, cron(0 20 * * ? *), rate(5 minutes).

secret_key

aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key

string

AWS secret access key.

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.

Support for the EC2_SECRET_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.

session_token

aliases: aws_session_token, security_token, aws_security_token, access_token

string

AWS STS session token for use with temporary credentials.

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_SESSION_TOKEN, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variables may also be used in decreasing order of preference.

The security_token and profile options are mutually exclusive.

Aliases aws_session_token and session_token were added in release 3.2.0, with the parameter being renamed from security_token to session_token in release 6.0.0.

Choices:

  • "present" ← (default)

  • "disabled"

  • "absent"

targets

list / elements=dictionary

A list of targets to add to or update for the rule.

arn

string / required

The ARN associated with the target.

ecs_parameters

dictionary

Contains the ECS task definition and task count to be used, if the event target is an ECS task.

task_count

integer

The number of tasks to create based on task_definition.

task_definition_arn

string / required

The full ARN of the task definition.

id

string / required

The unique target assignment ID.

input

json

A JSON object that will override the event data passed to the target.

If neither input nor input_path nor input_transformer is specified, then the entire event is passed to the target in JSON form.

input_path

string

A JSONPath string (e.g. $.detail) that specifies the part of the event data to be passed to the target.

If neither input nor input_path nor input_transformer is specified, then the entire event is passed to the target in JSON form.

input_transformer

dictionary

added in community.aws 4.1.0

Settings to support providing custom input to a target based on certain event data.

input_paths_map

dictionary

A dict that specifies the transformation of the event data to custom input parameters.

input_template

json

A string that templates the values input_paths_map extracted from the event data. It is used to produce the output you want to be sent to the target.

role_arn

string

The ARN of the IAM role to be used for this target when the rule is triggered.

validate_certs

boolean

When set to false, SSL certificates will not be validated for communication with the AWS APIs.

Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead.

Choices:

  • false

  • true ← (default)

Notes

Note

  • A rule must contain at least an event_pattern or schedule_expression. A rule can have both an event_pattern and a schedule_expression, in which case the rule will trigger on matching events as well as on a schedule.

  • When specifying targets, input, input_path, input_paths_map and input_template are mutually-exclusive and optional parameters.

  • 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.
