google_dns_record_set

Manages a set of DNS records within Google Cloud DNS. For more information see the official documentation and API.

Note: The Google Cloud DNS API requires NS records be present at all times. To accommodate this, when creating NS records, the default records Google automatically creates will be silently overwritten. Also, when destroying NS records, Terraform will not actually remove NS records, but will report that it did.

Example Usage

Binding a DNS name to the ephemeral IP of a new instance:

resource "google_dns_record_set" "frontend" {
  name = "frontend.${google_dns_managed_zone.prod.dns_name}"
  type = "A"
  ttl  = 300

  managed_zone = "${google_dns_managed_zone.prod.name}"

  rrdatas = ["${google_compute_instance.frontend.network_interface.0.access_config.0.assigned_nat_ip}"]
}

resource "google_compute_instance" "frontend" {
  name         = "frontend"
  machine_type = "g1-small"
  zone         = "us-central1-b"

  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-8"
    }
  }

  network_interface {
    network       = "default"
    access_config = {}
  }
}

resource "google_dns_managed_zone" "prod" {
  name     = "prod-zone"
  dns_name = "prod.mydomain.com."
}

Adding an A record

resource "google_dns_record_set" "a" {
  name = "backend.${google_dns_managed_zone.prod.dns_name}"
  managed_zone = "${google_dns_managed_zone.prod.name}"
  type = "A"
  ttl  = 300

  rrdatas = ["8.8.8.8"]
}

resource "google_dns_managed_zone" "prod" {
  name     = "prod-zone"
  dns_name = "prod.mydomain.com."
}

Adding an MX record

resource "google_dns_record_set" "mx" {
  name = "${google_dns_managed_zone.prod.dns_name}"
  managed_zone = "${google_dns_managed_zone.prod.name}"
  type = "MX"
  ttl  = 3600

  rrdatas = [
    "1 aspmx.l.google.com.",
    "5 alt1.aspmx.l.google.com.",
    "5 alt2.aspmx.l.google.com.",
    "10 alt3.aspmx.l.google.com.",
    "10 alt4.aspmx.l.google.com."
  ]
}

resource "google_dns_managed_zone" "prod" {
  name     = "prod-zone"
  dns_name = "prod.mydomain.com."
}

Adding an SPF record

Quotes ("") must be added around your rrdatas for a SPF record. Otherwise rrdatas string gets split on spaces.

resource "google_dns_record_set" "spf" {
  name = "frontend.${google_dns_managed_zone.prod.dns_name}"
  managed_zone = "${google_dns_managed_zone.prod.name}"
  type = "TXT"
  ttl  = 300

  rrdatas = ["\"v=spf1 ip4:111.111.111.111 include:backoff.email-example.com -all\""]
}

resource "google_dns_managed_zone" "prod" {
  name     = "prod-zone"
  dns_name = "prod.mydomain.com."
}

Argument Reference

The following arguments are supported:

• managed_zone - (Required) The name of the zone in which this record set will reside.

• name - (Required) The DNS name this record set will apply to.

• rrdatas - (Required) The string data for the records in this record set whose meaning depends on the DNS type. For TXT record, if the string data contains spaces, add surrounding \" if you don't want your string to get split on spaces.

• ttl - (Required) The time-to-live of this record set (seconds).

• type - (Required) The DNS record set type.

• project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

Attributes Reference

Only the arguments listed above are exposed as attributes.

Import

DNS record set can be imported using the zone name, record name and record type, e.g.

$ terraform import google_dns_record_set.frontend prod-zone/frontend.prod.mydomain.com./A

Note: The record name must include the trailing dot at the end.
