GitHub

To allow users to log in with GitHub credentials, you must use a GitHub App. We recommend that you set up a dedicated GitHub app for your SonarQube integration.

Creating a dedicated app for authentication

First, you’ll need to create a GitHub App. If you're already using a GitHub App for pull request decoration (see GitHub integration), you can also use it for user authentication and provisioning.

Configure the following settings in your GitHub App: 

  • General tab:
    • Homepage URL: The public URL of your SonarQube server. For example, https://sonarqube.mycompany.com. For security reasons, HTTP is not supported, and you must use HTTPS. The public URL is configured in SonarQube at Administration > General > Server base URL.
    • Callback URL: The public URL of your SonarQube server. For example, https://sonarqube.mycompany.com.
    • Webhooks: Deactivate the feature.
  • Permissions & events tab: 
    • Organization Permissions > Members: Set to Read-only.
    • Account permissions > Email addresses: Set to Read-only.
  • Install App tab: Click Install and validate the installation on each organization you need.
  • During App creation, or under the Advanced tab, you can make the App private or public:
    • Make it private if you only have one organization.
    • Make it public if you have several organizations from where you need users to authenticate and/or be provisioned. Don't forget to list those as allowed organizations in SonarQube (see below).

Setting your authentication settings in SonarQube

Connecting your GitHub App to SonarQube

Step 1: In SonarQube, Navigate to Administration > Configuration > General Settings > Authentication > GitHub and click Create configuration.

Step 2: Fill the following fields with information from your GitHub App:

    • Client ID
    • Client Secret
    • GitHub App ID
    • Private Key

Step 3: Fill the API url and WEB url fields as recommended by GitHub.

Step 4:
If your GitHub App is public, it is important that you enter the allowed organizations in the Organizations field. 

Step 5: Click Save configuration.

Selecting the user and group provisioning method

Once you've created your GitHub configuration, you can choose how users and groups are provisioned to SonarQube. For an overview of the available provisioning methods, see Authentication and provisioning.

Step 1: From the Authentication > GitHub tab, click Enable configuration.

Step 2: Select a provisioning method. The available options are: 

    • Just-in-Time user and group provisioning (default):
      • Users are provisioned when they authenticate through GitHub for the first time if the option Allow users to sign up is enabled.
      • User information and group memberships are updated at each authentication.
      • (Optional) You can synchronize GitHub teams with existing SonarQube groups of the same name with the Synchronize teams as groups option. 
    • Automatic user and group provisioning
      • Users and groups will be synchronized on an hourly basis. The first synchronization happens immediately when you enable the feature.
      • You can check the status of the synchronization on this configuration page, in the box Automatic user and group provisioning box.
      • If needed, you can manually trigger a synchronization by clicking Synchronize now.
      • Groups in SonarQube are named after the GitHub organizations and teams' names, ie. Organization/Team.
      • Personal user information (name and email address) is updated only upon user authentication.

Step 3: When you change a setting in your configuration, you can force SonarQube to check that it is valid by clicking Test configuration.

Step 4: Click Save.

From the login page, your users can now connect to SonarQube using their GitHub accounts by clicking the Login with GitHub button.
