Roles and permissions

Access control in Google Cloud Platform (GCP is controlled using Cloud Identity and Access Management (Cloud IAM). Cloud IAM allows you to set permissions specifying who has what kind of access to which resources in your project.

Cloud Source Repositories uses Cloud IAM for access control. You can use Cloud IAM to add team members to your project and to grant them permissions to create, view, and update repositories.

This page describes the Cloud IAM permissions and roles that apply to Cloud Source Repositories.


With Cloud IAM, every action on a repository in Cloud Source Repositories requires that the account initiating the action has the appropriate permissions. You don't grant specific permissions to an account. Instead, you grant a role that contains the appropriate set of permissions.

The following table describes the permissions available in Cloud Source Repositories.

source.repos.create Create a repository within a project.
