GCP Cloud DNS

Terraform can use google_dns_record_set resources to provide DNS records for your cluster.

In addition to the normal DNS variables, you will need to specify the managed_zone parameter. You can find your Managed Zone name in the GCP Netowrking Console.

If you haven’t set up a managed zone for the domain you’re using, you can do that with Terraform as well, just add this extra snippet in your .tf file:

resource "google_dns_managed_zone" "managed-zone" {
  name = "my-managed-zone"
  dns_name = "example.com."
  description "Managed zone for example.com."
}

In your gce.tf, you will want to enable the cloud-dns module:

module "cloud-dns" {
  source = "./terraform/gce/dns"
  control_count = "${var.control_count}"
  control_ips = "${module.control-nodes.control_ips}"
  domain = "mydomain.com"
  edge_count = "${var.edge_count}"
  edge_ips = "${module.edge-nodes.edge_ips}"
  lb_ip = "${module.network-lb.public_ip}"
  managed_zone = "my-cloud-dns-zone"
  short_name = "${var.short_name}"
  subdomain = "service"
  worker_count = "${var.worker_count}"
  worker_ips = "${module.worker-nodes.worker_ips}"
}
