Description

Create a datasource for instance groups to retrieve multiple instance groups with filters, such as AWS ASG

This will allow an easier management of MIGs especially when integrating with Google Load Balancer ( google_compute_backend_service ) while having different MIGs created

New or Affected Resource(s)

• google_compute_instance_groups
• google_container_node_pool
• google_container_node_pools

Potential Terraform Configuration

data "google_compute_instance_groups" "groups" {
  filter {
    name   = "key"
    values = ["Team"]
  }

  filter {
    name   = "value"
    values = ["Pets"]
  }
}

data "google_container_node_pools" "groups" {
  filter {
    name   = "key"
    values = ["Team"]
  }

  filter {
    name   = "value"
    values = ["Pets"]
  }
}
