Hi,

I am unsure how to declare more than one disk as part of the google_compute_disk_resource_policy_attachment policy. So far my code looks like this:

resource "google_compute_disk_resource_policy_attachment" "attachment" {
  name    = google_compute_resource_policy.snapshot_schedule.name
  disk    = google_compute_instance.vm_instance.name
  project = var.project
}

I would love to know the best way to add multiple disks here.
