alloydb-instance

AlloyDB cluster and instance with read replicas

This module manages the creation of AlloyDB cluster and configuration with/without automated backup policy, Primary node instance and Read Node Pools.

Simple example

This example shows how to create Alloydb cluster and instance with multiple read pools in GCP project.

module "alloydb" {
  source       = "./fabric/modules/alloydb-instance"
  project_id   = "myproject"
  cluster_id   = "alloydb-cluster-all"
  location     = "europe-west2"
  labels       = {}
  display_name = ""
  initial_user = {
    user     = "alloydb-cluster-full",
    password = "alloydb-cluster-password"
  }
  network_self_link = "projects/myproject/global/networks/default"

  automated_backup_policy = null

  primary_instance_config = {
    instance_id       = "primary-instance-1",
    instance_type     = "PRIMARY",
    machine_cpu_count = 2,
    database_flags    = {},
    display_name      = "alloydb-primary-instance"
  }
  read_pool_instance = [
    {
      instance_id       = "read-instance-1",
      display_name      = "read-instance-1",
      instance_type     = "READ_POOL",
      node_count        = 1,
      database_flags    = {},
      machine_cpu_count = 1
    },
    {
      instance_id       = "read-instance-2",
      display_name      = "read-instance-2",
      instance_type     = "READ_POOL",
      node_count        = 1,
      database_flags    = {},
      machine_cpu_count = 1
    }
  ]

}
