# atlas networking peering create gcp

Create a network peering connection between the Atlas VPC and your Google Cloud VPC.

The network peering create command checks if a VPC exists in the region you specify for your Atlas project. If one exists, this command creates the peering connection between that VPC and your VPC. If an Atlas VPC doesn't exist, this command creates one and creates a connection between it and your VPC.

To learn more about network peering connections, see [https://www.mongodb.com/docs/atlas/security-vpc-peering/.](https://www.mongodb.com/docs/atlas/security-vpc-peering/)

To use this command, you must authenticate with a user account, a service account, or an API key with the Project Owner role.
