The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa.
fqdn
Domain name of the endpoint to check. Either this or `ip_address` has to be provided. When both are given the `fqdn` is used in the `Host:` header of the HTTP request.
ip_address
IP address of the end-point to check. Either this or `fqdn` has to be provided.
port
The port on the endpoint on which you want Amazon Route 53 to perform health checks. Required for TCP checks.

  • 10
  • 30
The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health-check request.
resource_path
The path that you want Amazon Route 53 to request when performing health checks. The path can be any value for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, for example the file /docs/route53-health-check.html.
Required for all checks except TCP.
The path must begin with a /

    Choices:
  • HTTP
  • HTTPS
  • HTTP_STR_MATCH

  • 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

Examples

# Create a health-check for host1.example.com and use it in record

    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
    health_check: "{{ my_health_check.health_check.id }}"
