cloudwatchevent_rule - Manage CloudWatch Event rules and targets

New in version 2.2.

Synopsis

This module creates and manages CloudWatch event rules and targets.

Requirements (on host that executes module)

  • boto
  • boto3
  • python >= 2.6

Options

parameter required default choices comments
aws_access_key
 no
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
aws_secret_key
 no
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.
aliases: ec2_secret_key, secret_key
description
 no
A description of the rule
ec2_url
 no
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
 no
A string pattern (in valid JSON format) that is used to match against incoming events to determine if the rule should be triggered
name
 yes
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
(added in 1.6)
 no
Uses a boto profile. Only works with boto >= 2.24.0.
role_arn
 no
The Amazon Resource Name (ARN) of the IAM role associated with the rule
schedule_expression
 no
A cron or rate expression that defines the schedule the rule will trigger on. For example, cron(0 20 * * ? *), rate(5 minutes)
security_token
(added in 1.6)
 no
AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.
aliases: access_token
state
 no present
  • present
  • disabled
  • absent
Whether the rule is present (and enabled), disabled, or absent
targets
 no
A dictionary array of targets to add to or update for the rule, in the form { id: [string], arn: [string], input: [valid JSON string], input_path: [valid JSONPath string] }. id [required] is the unique target assignment ID. arn (required) is the Amazon Resource Name associated with the target. input (optional) is a JSON object that will override the event data when passed to the target. input_path (optional) is 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.
validate_certs
(added in 1.5)
 no yes
  • yes
  • no
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

Examples

- cloudwatchevent_rule:
    name: MyCronTask
    schedule_expression: "cron(0 20 * * ? *)"
    description: Run my scheduled task
    targets:
      - id: MyTargetId
        arn: arn:aws:lambda:us-east-1:123456789012:function:MyFunction

- cloudwatchevent_rule:
    name: MyDisabledCronTask
    schedule_expression: "cron(5 minutes)"
    description: Run my disabled scheduled task
    state: disabled
    targets:
      - id: MyOtherTargetId
        arn: arn:aws:lambda:us-east-1:123456789012:function:MyFunction
        input: '{"foo": "bar"}'

- cloudwatchevent_rule: name=MyCronTask state=absent

Return Values

Common return values are documented here Common Return Values, the following are the fields unique to this module:

name description returned type sample
targets CloudWatch Event target(s) assigned to the rule success list [{ 'arn': 'arn:aws:lambda:us-east-1:123456789012:function:MyFunction', 'id': 'MyTargetId' }]
rule CloudWatch Event rule data success dict { 'arn': 'arn:aws:events:us-east-1:123456789012:rule/MyCronTask', 'description': 'Run my scheduled task', 'name': 'MyCronTask', 'schedule_expression': 'cron(0 20 * * ? *)', 'state': 'ENABLED' }

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.

Note

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

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_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

Note

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

Note

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
