module: gcp_compute_http_health_check
description:
- An HttpHealthCheck resource. This resource defines a template for how
individual VMs should be checked for health, via HTTP.
short_description: Creates a GCP HttpHealthCheck
version_added: 2.6
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
state:
description:
- Whether the given object should exist in GCP
required: true
choices: ['present', 'absent']
default: 'present'
check_interval_sec:
description:
- How often (in seconds) to send a health check. The default value
is 5 seconds.
required: false
aliases: [check_interval_seconds]
description:
description:
- An optional description of this resource. Provide this property
when you create the resource.
required: false
healthy_threshold:
description:
- A so-far unhealthy instance will be marked healthy after this many
consecutive successes. The default value is 2.
required: false
host:
description:
- The value of the host header in the HTTP health check request. If
left empty (default value), the public IP on behalf of which this
health check is performed will be used.
required: false
name:
description:
- Name of the resource. Provided by the client when the resource is
created. The name must be 1-63 characters long, and comply with
RFC1035. Specifically, the name must be 1-63 characters long and
match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which
means the first character must be a lowercase letter, and all
following characters must be a dash, lowercase letter, or digit,
except the last character, which cannot be a dash.
required: true
port:
description:
- The TCP port number for the HTTP health check request.
- The default value is 80.
required: false
request_path:
description:
- The request path of the HTTP health check request.
- The default value is /.
required: false
timeout_sec:
description:
- How long (in seconds) to wait before claiming failure.
- The default value is 5 seconds. It is invalid for timeoutSec to
have greater value than checkIntervalSec.
required: false
aliases: [timeout_seconds]
unhealthy_threshold:
description:
- A so-far healthy instance will be marked unhealthy after this many
consecutive failures. The default value is 2.
required: false
