Cloud DNS & Shared VPC design
Usage
This blueprint shows how to create reusable and modular Cloud DNS architectures when using Shared VPC.
The goal is to provision dedicated Cloud DNS instances for application teams that want to manage their own DNS records, and configure DNS peering to ensure name resolution works in a common Shared VPC.
The blueprint will:
- Create a GCP project per application team based on the
teams
input variable - Create a VPC and Cloud DNS instance per application team
- Create a Cloud DNS private zone per application team in the form of
[teamname].[dns_domain]
, withteamname
anddns_domain
based on input variables - Configure DNS peering for each private zone from the Shared VPC to the DNS VPC of each application team
The resources created in this blueprint are shown in the high level diagram below:

Note that Terraform 0.13 at least is required due to the use of for_each
with modules.
