These credentials let Cloud Source Repositories access the\ncontents of the GitHub repository.\n\nIf you're using\n[GitHub organizations](https://help.github.com/articles/about-organizations/),\nwe recommend that you use a\n[machine user account](https://developer.github.com/v3/guides/managing-deploy-keys/#machine-users)\nspecifically dedicated to automated tasks,\nsuch as mirroring a repository. This account must have administrative access\nto your repository.\n\nMirror a GitHub repository\n--------------------------\n\nThis section shows how to mirror a GitHub repository to\nCloud Source Repositories.\n| **Note:** Make sure you're signed out of GitHub before you mirror a repository. Signing out helps ensure you select the right GitHub account when you connect the GitHub repository to Cloud Source Repositories.\n\n### Create a mirrored repository\n\nIn this process, you need your GitHub machine user credentials to grant\nGoogle Cloud read access to the GitHub repository.\n\n1. In the Google Cloud console, open Cloud Source Repositories.\n\n [Open Cloud Source Repositories](https://source.cloud.google.com/repos)\n2. Click **Add repository**.\n\n The **Add a repository** page opens.\n3. Select **Connect external repository** and click **Continue**.\n\n The **Connect external repository** page opens.\n4. In the **Project** drop-down list, select the Google Cloud\n project to which the mirrored repository belongs.\n\n If you don't have a project, you can click **Create project** to\n [create a project](https://cloud.google.com/source-repositories/docs/creating-an-empty-repository#creating_a_project).\n5. In the **Git provider** drop-down list, select **GitHub**.\n\n6. Select the checkbox to authorize Cloud Source Repositories to store your\n credentials.\n\n7. Click **Connect to GitHub**.\n\n8. Sign in to GitHub with your machine user credentials.\n\n9. Click **Authorize GoogleCloudPlatform**.\n\n This option grants Google Cloud read access to all repositories in the\n GitHub user account.\n\n When authorization finishes, you're returned to the **Connect external\n repository** page. A list of repositories opens.\n10. From the list of repositories, select the repository you want to mirror.\n\n11. Click **Connect Selected Repository**.\n\n The main repository page opens. This page contains a list of the\n repositories for this Google Cloud project, including the new\n repository you just created.\n\n### Identify GitHub repositories\n\nCloud Source Repositories makes it clear which of your repositories are\nmirrors of GitHub repositories:\n\n- Each GitHub repository is represented with the GitHub logo.\n- The name of the repository has `github_` added to the beginning of its name.\n\nForce a repository sync\n-----------------------\n\nAfter you set up mirroring, Cloud Source Repositories automatically syncs\nyour repository with the mirrored repository when a user commits a change.\nCloud Source Repositories lets you view the last time your mirrored\nrepository was synced and manually force a sync if necessary.\n\n1. In the Google Cloud console, browse to the mirrored GitHub repository.\n\n2. Click\n **Settings** *settings*.\n\n The sync status is displayed.\n\n3. To manually force a sync of the repositories, click **Sync from GitHub**.\n\n| **Note:** Repositories connected using an older version of the connected repository service may not have these options."]]
