You can create a Service Directory zone that allows your Google Cloud-based services to query your Service Directory namespace using Cloud DNS.
These instructions require that you already have a Service Directory namespace in place. If you do not, first create a namespace using the procedure in Configuring Service Directory.
Once you have attached a Service Directory zone to the namespace, all services and endpoints within the namespace become available over DNS on the private network. All service and endpoint updates are immediately reflected in their DNS records. However, neither service nor endpoint metadata is available over DNS.
Permissions required for this task
To perform this task, you must have been granted the following permissions or the following IAM roles.
Service Directory integration with Cloud DNS has the following limitations:
- You can only associate a Service Directory zone with a namespace when you create the zone.
- A Service Directory zone must be in the same project as the Service Directory namespace that it is associated with.
- A Service Directory zone cannot also be a forwarding zone, a regular private zone, or a public zone.
Creating a Service Directory zone backed by a namespace
You can only associate a Service Directory zone with a namespace when you create the zone. A Service Directory zone cannot also be a forwarding zone, a regular private zone, or a public zone.
- Go to the Cloud DNS page in the Google Cloud Console.
Go to the Cloud DNS page
- Click Create zone.
- In the Zone type section, click Private.
- Enter a name for the zone.
- Enter a DNS name for the zone.
- Under Options, select Use a service directory namespace.
- Under Networks, select one or more networks that can use the Service Directory zone.
- Select the Region where the namespace that you want to link lives.
- Select the Namespace that you want to link.
- Click Create.
gcloud dns managed-zones create SD_ZONE \ --dns-name DNS_NAME \ --description DESCRIPTION \ --visibility private \ --networks https://www.googleapis.com/compute/v1/projects/project_ID/global/networks/network \ --service-directory-namespace https://servicedirectory.googleapis.com/v1/projects/project_ID/locations/region/namespaces/namespace-name
Replace the following values:
SD_ZONE: the name of the Service Directory zone that you are creating.
DNS_NAME: the DNS name, such as
us-east1.example.com., for the new zone.
SD_ZONE: a description of the zone, such as
this zone is backed by Service Directory.
- https://www.googleapis.com/compute/v1/projects/PROJECT_ID/global/networks/NETWORK: the FQDN of the networks that can use the zone.
- https://www.servicedirectory.googleapis.com/v1/projects/PROJECT_ID/locations/REGION/registries/NAMESPACE_NAME: the FQDN of the namespace that you are linking.
Deleting the Service Directory zone
At any point, you can delete a Service Directory zone. This deletion happens through Cloud DNS and has no effect on any associated Service Directory namespaces. The associated namespace continues to be available for look up through HTTP and gRPC.
You can delete a
or namespace that has a Service Directory zone pointing to it without
deleting the zone. If you do, any further DNS queries for that service return
