gcp_compute_instance_group - Creates a GCP InstanceGroup

New in version 2.6.

Synopsis

  • Represents an Instance Group resource. Instance groups are self-managed and can contain identical or different instances. Instance groups do not use an instance template. Unlike managed instance groups, you must create and add instances to an instance group manually.

Requirements

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

  • python >= 2.6
  • requests >= 2.18.4
