Console

1. In the Google Cloud console, go to the Create a DNS zone page.

   Go to Create a DNS zone

2. For the Zone type, select Private.

3. Enter a Zone name such as my-new-zone.

4. Enter a DNS name suffix for the private zone. All records in the zone share this suffix, for example: example.private.

5. Optional: Add a description.

6. Under Options, select DNS peering.

7. Select the networks to which the private zone must be visible.

8. In Peer project, select a peer project.

9. In Peer network, select a peer network.

10. Click Create.

gcloud

1. In the project that contains the consumer VPC network, identify or create a service account.

2. Grant the DNS Peer role to the service account (from the previous step) in the project that contains the producer VPC network.

   gcloud projects add-iam-policy-binding PRODUCER_PROJECT_ID \
      --member=SERVICE_ACCOUNT \
      --role=roles/dns.peer
   

   Replace the following:

   • PRODUCER_PROJECT_ID: the ID of the project that contains the producer VPC network
   • SERVICE_ACCOUNT: the service account in the project that contains the consumer VPC network that was identified or created in step 1

3. In the project that contains the consumer VPC network, grant the DNS Administrator role to the service account and create a new managed private peering zone by running the dns managed-zones create command:

   gcloud dns managed-zones create NAME \
     --description=DESCRIPTION \
     --dns-name=DNS_SUFFIX \
     --networks=CONSUMER_VPC_NETWORK \
     --account=SERVICE_ACCOUNT \
     --target-network=PRODUCER_VPC_NETWORK \
     --target-project=PRODUCER_PROJECT_ID \
     --visibility=private
   

   Replace the following:

   • NAME: a name for your zone
   • DESCRIPTION: a description for your zone
   • DNS_SUFFIX: the DNS suffix for your zone, such as example.com
   • CONSUMER_VPC_NETWORK: the name of the consumer VPC network
   • SERVICE_ACCOUNT: the service account in the project that contains the consumer VPC network, identified in step 1
   • PRODUCER_VPC_NETWORK: the name of the producer VPC network
   • PRODUCER_PROJECT_ID: the ID of the project that contains the producer VPC network
