GCP Cloud DNS
=============

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

In addition to the :doc:`normal DNS variables <dns>`, 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:

.. code-block:: javascript

   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: 

.. code-block:: javascript

	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}"
	}
