Google Cloud Service Directory Module

This module allows managing a single Service Directory namespace, including multiple services, endpoints and IAM bindings at the namespace and service levels.

It can be used in conjunction with the DNS module to create [service-directory based DNS zones](https://cloud.google.com/service-directory/docs/configuring-service-directory-zone, offloading IAM control of A and SRV records at the namespace or service level to Service Directory. The last examples shows how to wire the two modules together.

Examples

Namespace with IAM

module "service-directory" {
  source      = "./fabric/modules/service-directory"
  project_id  = "my-project"
  location    = "europe-west1"
  name        = "sd-1"
  iam = {
    "roles/servicedirectory.editor" = [
      "serviceAccount:[email protected]"
    ]
  }
}
# tftest modules=1 resources=2

Services with IAM and endpoints

module "service-directory" {
  source      = "./fabric/modules/service-directory"
  project_id  = "my-project"
  location    = "europe-west1"
  name        = "sd-1"
  services = {
    one = {
      endpoints = ["first", "second"]
      metadata  = null
    }
  }
  service_iam = {
    one = {
      "roles/servicedirectory.editor" = [
        "serviceAccount:service-editor.example.com"
      ]
    }
  }
  endpoint_config = {
    "one/first"  = { address = "127.0.0.1", port = 80, metadata = {} }
    "one/second" = { address = "127.0.0.2", port = 80, metadata = {} }
  }
}
# tftest modules=1 resources=5

DNS based zone

Wiring a service directory namespace to a private DNS zone allows querying the namespace, and delegating control of DNS records at the namespace or service level. This effectively allows fine grained ACL control of Cloud DNS zones.

module "service-directory" {
  source      = "./fabric/modules/service-directory"
  project_id  = "my-project"
  location    = "europe-west1"
  name       = "apps"
  iam = {
    "roles/servicedirectory.editor" = [
      "serviceAccount:[email protected]"
    ]
  }
  services = {
    app1 = { endpoints = ["one"], metadata = null }
  }
  endpoint_config = {
    "app1/one" = { address = "127.0.0.1", port = 80, metadata = {} }
  }
}

module "dns-sd" {
  source                      = "./fabric/modules/dns"
  project_id                  = "my-project"
  type                        = "service-directory"
  name                        = "apps"
  domain                      = "apps.example.org."
  client_networks             = [var.vpc.self_link]
  service_directory_namespace = module.service-directory.id
}
# tftest modules=2 resources=5
