Synopsis

  • This module creates and manages CloudWatch event rules and targets.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3.6

  • boto3 >= 1.16.0

  • botocore >= 1.19.0

Parameters

Parameter

Comments

aws_access_key

aliases: ec2_access_key, 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.

aws_ca_bundle

path

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

Not used by boto 2 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.

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

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

aliases: ec2_secret_key, 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.

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:

  • no ← (default)

  • yes

description

string

A description of the rule.

ec2_url

aliases: aws_endpoint_url, endpoint_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.

event_pattern

string

A string pattern (in valid JSON format) 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

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.

region

aliases: aws_region, ec2_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

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).

security_token

aliases: aws_security_token, access_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.

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.

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

The full ARN of the task definition.

id

string / required

The unique target assignment ID.

input

string

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

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

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 “no”, SSL certificates will not be validated for communication with the AWS APIs.

Choices:

  • no

  • yes ← (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 and input_path are mutually-exclusive and optional parameters.

  • 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

  • When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.

  • Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.

  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
