google.cloud.gcp_compute_region_health_check module – Creates a GCP RegionHealthCheck

Note

This module is part of the google.cloud collection (version 1.1.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install google.cloud. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: google.cloud.gcp_compute_region_health_check.

Synopsis

  • Health Checks determine whether instances are responsive and able to do work.

  • They are an important part of a comprehensive load balancing configuration, as they enable monitoring instances behind load balancers.

  • Health Checks poll instances at a specified interval. Instances that do not respond successfully to some number of probes in a row are marked as unhealthy. No new connections are sent to unhealthy instances, though existing connections will continue. The health check will continue to poll unhealthy instances. If an instance later responds successfully to some number of consecutive probes, it is marked healthy again and can receive new connections.

Requirements

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

  • python >= 2.6

  • requests >= 2.18.4

  • google-auth >= 1.3.0
