Access control with IAM

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

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

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


With 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.

Permission Description
source.repos.list List repositories within a project.
source.repos.create Create a repository within a project.
source.repos.get Clone, fetch, and browse repositories.
source.repos.update Push changes to a repository.
source.repos.updateRepoConfig Change a repository configuration.
source.repos.delete Delete a repository.
source.repos.getIamPolicy Read/view the IAM policy of a repository.

Custom roles

In addition to the predefined roles, Cloud Source Repositories also supports custom roles. For more information, see Creating and managing custom roles in the IAM documentation.

Granting member access

In IAM, you grant access to members. There are multiple types of members. For a complete list, see Concepts related to identity.

For specific steps on granting member access, see Granting, changing, and revoking access to resources.

You can't make a Google Cloud repository public. As a result, Cloud Source Repositories doesn't support the following member types:

  • allAuthenticatedUsers
  • allUsers
