module: gcp_compute_instance_group_manager
description:
- Creates a managed instance group using the information that you specify in the request.
After the group is created, it schedules an action to create instances in the group
using the specified instance template. This operation is marked as DONE when the
group is created even if the instances in the group have not yet been created. You
must separately verify the status of the individual instances.
- A managed instance group can have up to 1000 VM instances per group.
short_description: Creates a GCP InstanceGroupManager
version_added: 2.6
