cloud-foundation-fabric/modules/dns

Google Cloud DNS Module

This module allows simple management of Google Cloud DNS zones and records. It supports creating public, private, forwarding, peering, service directory and reverse-managed based zones.

For DNSSEC configuration, refer to the dns_managed_zone documentation.

Examples

Private Zone

module "private-dns" {
  source          = "./fabric/modules/dns"
  project_id      = "myproject"
  type            = "private"
  name            = "test-example"
  domain          = "test.example."
  client_networks = [var.vpc.self_link]
  recordsets = {
    "A localhost" = { records = ["127.0.0.1"] }
    "A myhost"    = { ttl = 600, records = ["10.0.0.120"] }
  }
}
# tftest modules=1 resources=3 inventory=private-zone.yaml

Forwarding Zone

module "private-dns" {
  source          = "./fabric/modules/dns"
  project_id      = "myproject"
  type            = "forwarding"
  name            = "test-example"
  domain          = "test.example."
  client_networks = [var.vpc.self_link]
  forwarders      = { "10.0.1.1" = null, "1.2.3.4" = "private" }
}
# tftest modules=1 resources=1 inventory=forwarding-zone.yaml

Peering Zone

module "private-dns" {
  source          = "./fabric/modules/dns"
  project_id      = "myproject"
  type            = "peering"
  name            = "test-example"
  domain          = "."
  description     = "Forwarding zone for ."
  client_networks = [var.vpc.self_link]
  peer_network    = var.vpc2.self_link
}

Routing Policies

module "private-dns" {

  name            = "test-example"
  domain          = "test.example."
  client_networks = [var.vpc.self_link]
  recordsets = {
    "A regular" = { records = ["10.20.0.1"] }
    "A geo" = {
      geo_routing = [
        { location = "europe-west1", records = ["10.0.0.1"] },
        { location = "europe-west2", records = ["10.0.0.2"] },
        { location = "europe-west3", records = ["10.0.0.3"] }
      ]
    }

    "A wrr" = {
      ttl = 600
      wrr_routing = [
        { weight = 0.6, records = ["10.10.0.1"] },
        { weight = 0.2, records = ["10.10.0.2"] },
        { weight = 0.2, records = ["10.10.0.3"] }
      ]
    }
  }
}

Reverse Lookup Zone

module "private-dns" {
  source          = "./fabric/modules/dns"
  project_id      = "myproject"
  type            = "reverse-managed"
  name            = "test-example"
  domain          = "0.0.10.in-addr.arpa."
  client_networks = [var.vpc.self_link]
}
# tftest modules=1 resources=1 inventory=reverse-zone.yaml

Public Zone

module "public-dns" {
  source     = "./fabric/modules/dns"
  project_id = "myproject"
  type       = "public"
  name       = "example"
  domain     = "example.com."
  recordsets = {
    "A myhost" = { ttl = 300, records = ["127.0.0.1"] }
  }
}
