# Google Cloud Service Directory Module
|
|
|
|
This module allows managing a single [Service Directory](https://cloud.google.com/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](../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
|
|
|
|
```hcl
|
|
module "service-directory" {
|
|
source = "./modules/service-directory"
|
|
project_id = "my-project"
|
|
location = "europe-west1"
|
|
name = "sd-1"
|
|
iam = {
|
|
"roles/servicedirectory.editor" = [
|
|
"serviceAccount:namespace-editor@example.com"
|
|
]
|
|
}
|
|
}
|
|
```
|
|
|
|
### Services with IAM and endpoints
|
|
|
|
```hcl
|
|
module "service-directory" {
|
|
source = "./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 = {} }
|
|
}
|
|
}
|
|
```
|
|
|
|
### 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.
|
|
|
|
```hcl
|
|
module "service-directory" {
|
|
source = "./modules/service-directory"
|
|
project_id = "my-project"
|
|
location = "europe-west1"
|
|
name = "apps"
|
|
iam = {
|
|
"roles/servicedirectory.editor" = [
|
|
"serviceAccount:namespace-editor@example.com"
|
|
]
|
|
}
|
|
services = {
|
|
app1 = { endpoints = ["one"], metadata = null }
|
|
}
|
|
endpoint_config = {
|
|
"app1/one" = { address = "127.0.0.1", port = 80, metadata = {} }
|
|
}
|
|
}
|
|
|
|
module "dns-sd" {
|
|
source = "./modules/dns"
|
|
project_id = "my-project"
|
|
type = "service-directory"
|
|
name = "apps"
|
|
domain = "apps.example.org."
|
|
client_networks = [local.vpc_self_link]
|
|
service_directory_namespace = module.service-directory.id
|
|
}
|
|
|
|
```
