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. Prior to release 6.0.0 these environment variables will be ignored if the profile parameter is passed. After release 6.0.0 access_key will always fall back to the environment variables if set.

The aws_access_key and profile options are mutually exclusive.

The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK.

The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01.

Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.

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

dictionary

A dictionary to modify the botocore configuration.

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.

The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.

Choices:

  • false ← (default)

  • true

description

string

A description of the rule.

endpoint_url

aliases: ec2_url, aws_endpoint_url, s3_url

string

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.

Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.

event_pattern

json

A string pattern that is used to match against incoming events to determine if the rule should be triggered.

name

string / required

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 AWS_PROFILE environment variable may also be used. Prior to release 6.0.0 the AWS_PROFILE environment variable will be ignored if any of access_key, secret_key, or session_token are passed. After release 6.0.0 profile will always fall back to the AWS_PROFILE environment variable if set.

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.

The AWS_REGION or EC2_REGION environment variables may also be used.

See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region.

The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01

Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.

role_arn

string

The Amazon Resource Name (ARN) of the IAM role associated with the rule.

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).

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.

The AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference. Prior to release 6.0.0 these environment variables will be ignored if the profile parameter is passed. After release 6.0.0 secret_key will always fall back to the environment variables if set.

The secret_key and profile options are mutually exclusive.

The aws_secret_access_key alias was added in release 5.1.0 for consistency with the AWS botocore SDK.

The ec2_secret_key alias has been deprecated and will be removed in a release after 2024-12-01.

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. Prior to release 6.0.0 these environment variables will be ignored if the profile parameter is passed. After release 6.0.0 session_token will always fall back to the environment variables if set.

state

string

Whether the rule is present (and enabled), disabled, or absent.

Choices:

  • "present" ← (default)

  • "disabled"

  • "absent"

targets

list / elements=dictionary

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

Default: []

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.
