Terraform

Resources

• google_alloydb_cluster: Manages an AlloyDB cluster.
• google_alloydb_instance: Manages an AlloyDB instance within a cluster.

Example

data "google_project" "project" {}
resource "google_compute_network" "default" {
  name = "alloydb-network"
}
resource "google_compute_global_address" "private_ip_alloc" {
  name          =  "alloydb-cluster"
