Integrate your GitLab server with Bitbucket Cloud

Note: Starting from GitLab 11.4, OmniAuth is enabled by default. If you’re using an earlier version, you must explicitly enable it.

You can set up Bitbucket.org as an OAuth2 provider so that you can use your Bitbucket.org account credentials to sign into GitLab or import your projects from Bitbucket.org.

Bitbucket OmniAuth provider

To enable the Bitbucket OmniAuth provider you must register your application with Bitbucket.org. Bitbucket generates an application ID and secret key for you to use.

  1. Sign in to Bitbucket.org.
  2. Navigate to your individual user settings (Bitbucket settings) or a team’s settings (Manage team), depending on how you want the application registered. It does not matter if the application is registered as an individual or a team, that is entirely up to you.
  3. In the left menu under Access Management, select OAuth.
  4. Select Add consumer.
  5. Provide the required details:

    • Name: This can be anything. Consider something like <Organization>'s GitLab or <Your Name>'s GitLab or something else descriptive.
    • Application description: (Optional) Fill this in if you wish.
    • Callback URL: (Required in GitLab versions 8.15 and greater) The URL to your GitLab installation, such as https://gitlab.example.com/users/auth. Be sure to append /users/auth to the end of the callback URL to prevent an OAuth2 convert redirect vulnerability. Leaving this field empty results in an Invalid redirect_uri message.
    • URL: The URL to your GitLab installation, such as https://gitlab.example.com.
  6. Grant at least the following permissions:

    Account: Email, Read
    Projects: Read
    Repositories: Read
    Pull Requests: Read
    Issues: Read
    Wiki: Read and Write
    

    Bitbucket OAuth settings page

  7. Select Save.
  8. Select your newly created OAuth consumer, and you should now see a Key and Secret in the list of OAuth consumers. Keep this page open as you continue the configuration.

  9. On your GitLab server, open the configuration file:

    # For Omnibus packages
    sudo editor /etc/gitlab/gitlab.rb
    
    # For installations from source
    sudo -u git -H editor /home/git/gitlab/config/gitlab.yml
    
  10. Add the Bitbucket provider configuration:

    For Omnibus packages:

    gitlab_rails['omniauth_providers'] = [
      {
        "name" => "bitbucket",
        "app_id" => "BITBUCKET_APP_KEY",
        "app_secret" => "BITBUCKET_APP_SECRET",
        "url" => "https://bitbucket.org/"
      }
    ]
    

    For installations from source:

    omniauth:
      enabled: true
      providers:
        - { name: 'bitbucket',
            app_id: 'BITBUCKET_APP_KEY',
            app_secret: 'BITBUCKET_APP_SECRET',
            url: 'https://bitbucket.org/' }
    

Where BITBUCKET_APP_KEY is the Key and BITBUCKET_APP_SECRET the Secret from the Bitbucket application page.

  1. Save the configuration file.
  2. For the changes to take effect, reconfigure GitLab if you installed via Omnibus GitLab, or restart if installed from source.

On the sign-in page there should now be a Bitbucket icon below the regular sign-in form. Click the icon to begin the authentication process. Bitbucket asks the user to sign in and authorize the GitLab application. If successful, the user is returned to GitLab and signed in.

Bitbucket project import

After the above configuration is set up, you can use Bitbucket to sign into GitLab and start importing your projects.

If you want to import projects from Bitbucket, but don’t want to enable signing in, you can disable Sign-Ins in the admin panel.
