google_compute_region_instance_group

Get a Compute Region Instance Group within GCE. For more information, see the official documentation and API.

data "google_compute_region_instance_group" "group" {
    name = "instance-group-name"
}

The most common use of this datasource will be to fetch information about the instances inside regional managed instance groups, for instance:

resource "google_compute_region_instance_group_manager" "foo" {
    name = "some_name"
    ...
    base_instance_name = "foo"
    ...
    instance_template = "${google_compute_instance_template.foo.self_link}"
    target_pools = ["${google_compute_target_pool.foo.self_link}"]
    ...
}

data "google_compute_region_instance_group" "data_source" {
    self_link = "${google_compute_region_instance_group_manager.foo.instance_group}"
}
