title: GitLab Integration
url: /analysis/gitlab-integration/
---
SonarQube's integration with GitLab Self-Managed and GitLab.com allows you to maintain code quality and security in your GitLab projects.
With this integration, you'll be able to:
- **Authenticate with GitLab** - Sign in to SonarQube with your GitLab credentials.
- **Import your GitLab projects** - Import your GitLab Projects into SonarQube to easily set up SonarQube projects.
- **Analyze projects with GitLab CI/CD** - Integrate analysis into your build pipeline. Starting in [Developer Edition](https://redirect.sonarsource.com/editions/developer.html), SonarScanners running in GitLab CI/CD jobs can automatically detect branches or merge requests being built so you don't need to specifically pass them as parameters to the scanner.
- **Report your Quality Gate status to your merge requests** - (starting in [Developer Edition](https://redirect.sonarsource.com/editions/developer.html)) See your Quality Gate and code metric results right in GitLab so you know if it's safe to merge your changes.
## Prerequisites
Integration with GitLab Self-Managed requires at least GitLab Self-Managed version 11.7.
### Branch Analysis
Community Edition doesn't support the analysis of multiple branches, so you can only analyze your main branch. Starting in [Developer Edition](https://redirect.sonarsource.com/editions/developer.html), you can analyze multiple branches and merge requests.
## Authenticating with GitLab
You can delegate authentication to GitLab using a dedicated GitLab OAuth application.
### Creating a GitLab OAuth app
You can find general instructions for creating a GitLab OAuth app [here](https://docs.gitlab.com/ee/integration/oauth_provider.html).
Specify the following settings in your OAuth app:
- **Name** – your app's name, such as SonarQube.
- **Redirect URI** – enter your SonarQube URL with the path `/oauth2/callback/gitlab`. For example, `https://sonarqube.mycompany.com/oauth2/callback/gitlab`.
- **Scopes** – select **api** if you plan to enable group synchronization. Select **read_user** if you only plan to delegate authentication.
After saving your application, GitLab takes you to the app's page. Here you find your **Application ID** and **Secret**. Keep these handy, open your SonarQube instance, and navigate to **Administration > Configuration > General Settings > ALM Integrations > GitLab > Authentication**. Set the following settings to finish setting up GitLab authentication:
- **Enabled** – set to `true`.
- **Application ID** – the Application ID is found on your GitLab app's page.
- **Secret** – the Secret is found on your GitLab app's page.
On the login form, the new "Log in with GitLab" button allows users to connect with their GitLab accounts.
### GitLab group synchronization
Enable **Synchronize user groups** at **Administration > Configuration > General Settings > ALM Integrations > GitLab** to associate GitLab groups with existing SonarQube groups of the same name. GitLab users inherit membership to subgroups from parent groups.
To synchronize a GitLab group or subgroup with a SonarQube group, name the SonarQube group with the full path of the GitLab group or subgroup URL.
For example, with the following GitLab group setup:
- GitLab group = My Group
- GitLab subgroup = My Subgroup
- GitLab subgroup URL = `https://YourGitLabURL.com/my-group/my-subgroup`
You should name your SonarQube group `my-group` to synchronize it with your GitLab group and `my-group/my-subgroup` to synchronize it with your GitLab subgroup.
## Importing your GitLab projects into SonarQube
Setting up the import of GitLab projects into SonarQube allows you to easily create SonarQube projects from your GitLab projects. If you're using [Developer Edition](https://redirect.sonarsource.com/editions/developer.html) or above, this is also the first step in adding merge request decoration.
To set up the import of GitLab projects:
1. Set your global settings
1. Add a personal access token for importing repositories
### Setting your global settings
To import your GitLab projects into SonarQube, you need to first set your global SonarQube settings. Navigate to **Administration > Configuration > General Settings > ALM Integrations**, select the **GitLab** tab, and specify the following settings:
- **Configuration Name** (Enterprise and Data Center Edition only) – The name used to identify your GitLab configuration at the project level. Use something succinct and easily recognizable.
- **GitLab URL** – The GitLab API URL.
- **Personal Access Token** – A GitLab user account is used to decorate Merge Requests. We recommend using a dedicated GitLab account with at least **Reporter** [permissions](https://docs.gitlab.com/ee/user/permissions.html) (the account needs permission to leave comments). You need a personal access token from this account with the scope authorized for **api** for the repositories that will be analyzed. This personal access token is used to merge request decoration. You'll be asked for another personal access token for importing projects in the following section.
### Adding a personal access token for importing projects
After setting these global settings, you can add a project from GitLab by clicking the **Add project** button in the upper-right corner of the **Projects** homepage and selecting **GitLab**.
Then, you'll be asked to provide a personal access token with `read_api` scope so SonarQube can access and list your GitLab projects. This token will be stored in SonarQube and can be revoked at anytime in GitLab.
After saving your Personal Access Token, you'll see a list of your GitLab projects that you can **set up** to add them to SonarQube. Setting up your projects this way also sets your project settings for merge request decoration.
For information on analyzing your projects with GitLab CI/CD, see the following section.
## Analyzing projects with GitLab CI/CD
SonarScanners running in GitLab CI/CD jobs can automatically detect branches or merge requests being built so you don't need to specifically pass them as parameters to the scanner.
To analyze your projects with GitLab CI/CD, you need to:
- Set your environment variables.
- Configure your gilab-ci.yml file.
The following sections detail these steps.
[[warning]]
| You need to disable git shallow clone to make sure the scanner has access to all of your history when running analysis with GitLab CI/CD. For more information, see [Git shallow clone](https://docs.gitlab.com/ee/user/project/pipelines/settings.html#git-shallow-clone).
### Setting environment variables
You can set environment variables securely for all pipelines in GitLab's settings. See GitLab's documentation on [Creating a Custom Environment Variable](https://docs.gitlab.com/ee/ci/variables/#creating-a-custom-environment-variable) for more information.
You need to set the following environment variables in GitLab for analysis:
- `SONAR_TOKEN` – Generate a SonarQube [token](/user-guide/user-token/) for GitLab and create a custom environment variable in GitLab with `SONAR_TOKEN` as the **Key** and the token you generated as the **Value**.
- `SONAR_HOST_URL` – Create a custom environment variable with `SONAR_HOST_URL` as the **Key** and your SonarQube server URL as the **Value**.
### Configuring your gitlab-ci.yml file
This section shows you how to configure your GitLab CI/CD `gitlab-ci.yml` file. The `allow_failure` parameter in the examples allows a job to fail without impacting the rest of the CI suite.
You'll set up your build according to your SonarQube edition:
- **Community Edition** – Community Edition doesn't support multiple branches, so you should only analyze your main branch. You can restrict analysis to your main branch by adding the branch name to the `only` parameter in your .yml file.
- **Developer Edition and above** By default, GitLab will build all branches but not Merge Requests. To build Merge Requests, you need to update the `.gitlab-ci.yml` file by adding `merge_requests` to the `only` parameter in your .yml. See the example configurations below for more information.
Click the scanner you're using below to expand an example configuration:

| ```
|
|
| **Project key**
| A project key has to be provided through `sonar-project.properties` or through the command line parameter. For more information, see the [SonarScanner](/analysis/scan/sonarscanner/) documentation.
|
| **Self-signed certificates**
| If you secure your SonarQube instance with a self-signed certificate, you may need to build a custom image based on `sonarsource/sonar-scanner-cli`. See the section **Advanced Docker Configuration** within the [SonarScanner](/analysis/scan/sonarscanner/) documentation.
|
#### **Failing the pipeline job when the Quality Gate fails**
In order for the Quality Gate to fail on the GitLab side when it fails on the SonarQube side, the scanner needs to wait for the SonarQube Quality Gate status. To enable this, set the `sonar.qualitygate.wait=true` parameter in the `.gitlab-ci.yml` file.
You can set the `sonar.qualitygate.timeout` property to an amount of time (in seconds) that the scanner should wait for a report to be processed. The default is 300 seconds.
### For more information
For more information on configuring your build with GitLab CI/CD, see the [GitLab CI/CD Pipeline Configuration Reference](https://gitlab.com/help/ci/yaml/README.md).
## Reporting your Quality Gate status in GitLab
After you've set up SonarQube to import your GitLab projects as shown in the previous section, SonarQube can report your Quality Gate status and analysis metrics directly to GitLab.
To do this, add a project from GitLab by clicking the **Add project** button in the upper-right corner of the **Projects** homepage and select **GitLab** from the drop-down menu.
Then, follow the steps in SonarQube to analyze your project. SonarQube automatically sets the project settings required to show your Quality Gate in your merge requests.
[[info]]
| To report your Quality Gate status in your merge requests, a SonarQube analysis needs to be run on your code. You can find the additional parameters required for merge request analysis on the [Pull Request Analysis](/analysis/pull-request/) page.
If you're creating your projects manually or adding Quality Gate reporting to an existing project, see the following section.
### Reporting your Quality Gate status in manually created or existing projects
SonarQube can also report your Quality Gate status to GitLab merge requests for existing and manually-created projects. After you've updated your global settings as shown in the **Importing your GitLab projects into SonarQube** section above, set the following project settings at **Project Settings > General Settings > DevOps Platform Integration**:
- **Configuration name** – The configuration name that corresponds to your GitLab instance.
- **Project ID** – your GitLab Project ID found in GitLab
### Advanced configuration
[[collapse]]
| ## Reporting your Quality Gate status on pull requests in a mono repository
|
| _Reporting Quality Gate statuses to merge requests in a mono repository setup is supported starting in [Enterprise Edition](https://redirect.sonarsource.com/editions/enterprise.html)._
|
| In a mono repository setup, multiple SonarQube projects, each corresponding to a separate project within the mono repository, are all bound to the same Bitbucket Cloud repository. You'll need to set up each SonarQube project that's part of a mono repository to report your Quality Gate status.
|
| You need to set up projects that are part of a mono repository manually as shown in the **Displaying your Quality Gate status in manually created or existing project** section above. You also need to set the **Enable mono repository support** setting to true at **Project Settings > General Settings > DevOps Platform Integration**.
|
| After setting your project settings, ensure the correct project is being analyzed by adjusting the analysis scope and pass your project names to the scanner. See the following sections for more information.
|
| ### Ensuring the correct project is analyzed
| You need to adjust the analysis scope to make sure SonarQube doesn't analyze code from other projects in your mono repository. To do this set up a **Source File Inclusion** for your project at **Project Settings > Analysis Scope** with a pattern that will only include files from the appropriate folder. For example, adding `./MyFolderName/**/*` to your inclusions would only include analysis of code in the `MyFolderName` folder. See [Narrowing the Focus](/project-administration/narrowing-the-focus/) for more information on setting your analysis scope.
|
| ### Passing project names to the scanner
| Because of the nature of a mono repository, SonarQube scanners might read all project names of your mono repository as identical. To avoid having multiple projects with the same name, you need to pass the `sonar.projectName` parameter to the scanner. For example, if you're using the Maven scanner, you would pass `mvn sonar:sonar -Dsonar.projectName=YourProjectName`.
[[collapse]]
| ## Configuring multiple ALM instances
| SonarQube can report your Quality Gate status to multiple ALM instances. To do this, you need to create a configuration for each ALM instance and assign that configuration to the appropriate projects.
|
| - As part of [Developer Edition](https://redirect.sonarsource.com/editions/developer.html), you can create one configuration for each ALM.
|
| - Starting in [Enterprise Edition](https://redirect.sonarsource.com/editions/enterprise.html), you can create multiple configurations for each ALM. If you have multiple configurations of the same ALM connected to SonarQube, you have to create projects manually.
[[collapse]]
| ## Linking issues
| When adding a Quality Gate status to your merge requests, individual issues will be linked to their SonarQube counterparts automatically. For this to work correctly, you need to set the instance's **Server base URL** (**[Administration > Configuration > General Settings > General > General](/#sonarqube-admin#/admin/settings/)**) correctly. Otherwise, the links will default to `localhost`.
