  • 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 http://boto.readthedocs.org/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

    resource_path: /
    string_match: "Hello"
    request_interval: 10
    failure_threshold: 2
  register: my_health_check

- route53:
    action: create
    zone: "example.com"
    type: CNAME
    record: "www.example.com"
    value: host1.example.com
    ttl: 30
    # Routing policy
    identifier: "host1@www"
    weight: 100
