GitLab Integration

Follow the instructions on this page to integrate with VCS repositories that are hosted on gitlab.com, self-hosted GitLab Community Edition (CE), or self-hosted GitLab Enterprise Edition (EE) server.

A GitLab integration enables the following features in YouTrack:

Apply commands to YouTrack issues in commit messages. For more information, see Apply Commands in VCS Commits.
Track commits that are related to specific issues in the activity stream for each issue. For more information, see Commits.
Display the status of pull (merge) requests directly in the activity stream of any issue that is referenced in the title or description of the pull request. For details, see Pull Requests.
Add links to YouTrack issues in commit messages. For more information, see Link Issues in VCS Commits.

The ability to set YouTrack issue IDs as links in commit messages is not fully supported in GitLab. The Custom Issue Tracker service that enables this feature in GitLab does not support issue URLs in the format that is used by YouTrack. All of the integration features are handled properly on the YouTrack side, but links from GitLab to YouTrack are not set correctly.

Prerequisites

YouTrack is accessible to inbound connections. Specifically, you need to make sure that your network doesn't block connections between your VCS server and YouTrack.
The account that you use to connect to GitLab has access to the GitLab project that you want to manage with this integration. This is the user account whose private access token is used for authentication. You can either use an account that has at least Master or Owner access level in the project or a GitLab administrator account.

If you're integrating with a GitLab CE or GitLab EE installation and want to establish a secure (HTTPS) connection with the server, you may need to import the SSL certificate for your GitLab server into YouTrack.

If your GitLab server has a valid certificate that is signed by a well-known certificate authority (CA), the JVM vendor may have already added the root (CA) certificate to the certificate store. You should be able to connect to the server without importing its SSL certificate.
If the certificate for your server is self-signed, you need to import the certificate and public key to establish a secure connection. For security, use this option only when both YouTrack and your GitLab server run on a private computer network. For instructions, see SSL Certificates.

Enable the YouTrack Integration in GitLab

The first thing you should do is enable the YouTrack integration in GitLab. This formats references to YouTrack issues in commit messages as links to the target issues in YouTrack. The following limitations apply:

This functionality is supported in GitLab versions 11.9.0 and later.
The integration only recognizes issue prefixes that begin with an uppercase letter. Issue prefixes that begin with lowercase letters or numeric values are not recognized.

To learn more about this integration, refer to the GitLab Docs.

To enable the YouTrack Integration:

Access the project that you want to integrate with in GitLab.
From the Settings menu, select Integrations.
In the Project services section of the page, select YouTrack

Specify values for the following settings:

Setting	Description
Description	Enter any value. Use this setting to indicate which YouTrack service you've integrated with.
Project url	Enter the base URL for your YouTrack service. For YouTrack InCloud instances, your base URL includes the trailing `/youtrack`. YouTrack issues aren't accessible from URLs that end in a project name. Don't attempt to add the project name or ID to the URL.
Issues url	Enter your base URL, followed by `issue/:id`.

Setting

Description

Enter any value. Use this setting to indicate which YouTrack service you've integrated with.

Project url

Enter the base URL for your YouTrack service.

For YouTrack InCloud instances, your base URL includes the trailing /youtrack.
YouTrack issues aren't accessible from URLs that end in a project name. Don't attempt to add the project name or ID to the URL.

Issues url

Enter your base URL, followed by issue/:id.

Enable the Active option.
Click the Test settings and save changes button.

With this configuration, any reference that is recognized as an issue in YouTrack is set as a link.

The link is formed according to the pattern that is set for the Issues url.
The :id placeholder is replaced with the issue ID, which includes the project prefix.

This means that you can add links in GitLab to any issue in any project from your YouTrack installation, even when you haven't configured an integration for the project in YouTrack. However, related VCS changes are only shown in issues where the GitLab integration has been set up for the project in YouTrack. To enable this integration feature, continue with the setup as described in the following section.

Connect to a GitLab Repository

Next, you need to establish a connection between a project in YouTrack and a repository in GitLab. To connect with GitLab, you need to generate and store a personal access token. This token grants YouTrack access to the repository based on the access that is granted to your GitLab account.

You can use a single access token to set up multiple integrations. If you don't already have a personal access token, you can use the direct link from YouTrack to generate it during this setup procedure.

To connect to a GitLab repository:

Open the Administration > VCS Integrations page in YouTrack.
Click the New VCS Integration button.
- The New VCS Integration dialog opens.
From the Main YouTrack project list, select the name of the primary project that you want to integrate with the VCS repository. You can add integrations with additional YouTrack projects after you have set up the connection to the repository.
For the Server type, select GitLab.
Paste the URL that points to your GitLab repository into the Repository URL input field.
Paste your personal access token into the Personal access token input field. If you don't already have an access token, follow these steps:
- Click the Generate token link to open the Personal Access Tokens page in GitLab.
- Enter a name for the token.
- Set the Scopes for the token. The VCS integration requires api, read_user, and read_repository.
- Click the Create personal access token button.
- Copy the token to the clipboard.
Switch back to the New VCS Integration dialog in YouTrack and paste the token into the Personal access token field.
Click the Save button.
- Your YouTrack project is integrated with the selected repository in GitLab.
- Commits from the GitLab repository that reference an issue in the project are displayed in the activity stream of the referenced issue.
- The sidebar displays additional settings for configuring the VCS integration.
To learn more about these settings, see Integration Settings.

Advanced Server Settings

If you are unable to establish a connection to your repository using the basic settings on the New VCS Integration dialog, click the Show advanced server settings link.

You only need to enter values for these settings when you haven't set up a VCS integration with the target server. If you already have a working integration with a single repository on the server, you can add integrations with other repositories without setting these parameters again.

Use the following guidelines to set the values for these settings:

Setting	Description
URL	This setting helps to identify the path to the GitLab repository. If the repositories for your GitLab CE or EE server are available under `https://host:port/SOME_CONTEXT_PATH`, YouTrack is unable to where this context path ends and the actual path to the repository begins. To resolve this problem, enter the base URL for your GitLab server plus the context path that points to your repository. For example: `https://host:port/context_path`
SSL key	If your server environment is set up to require client SSL authentication, select the keystore that contains the private key for your YouTrack server. This key identifies your YouTrack server when it tries to establish a connection with GitLab. This setting is only used to support HTTPS authentication as required by connections to your internal network. The list only displays SSL keys that are already imported into YouTrack. To learn how to generate keystore files and upload them to YouTrack, see SSL Keys.

Integration Settings

By default, the VCS integration processes changes that are committed to the repository by any user in any branch. Any user who has access to the issue in YouTrack can view these changes in the issue activity stream.

If you only want to process changes by specific users in designated branches or restrict the visibility of VCS changes in YouTrack, you can customize the integration settings. Use following settings to customize the integration:

Setting	Description
Repository	Displays the path to the repository in the integrated version control system. If needed, you can edit the location of the repository after you have set up the integration. For instructions, see Edit Repository Settings.
Main YouTrack project	Sets the primary project in which the VCS integration is active.
Additional projects	Integrates the linked repository with one or more additional projects.
Committers	Restricts the ability to update issues with commands in commit messages to members of the specified group. VCS changes from users who are not members of the selected group are still attached to related issues, but any commands that are specified in their commits are ignored.
Monitored branches	Stores the names of the branches that you want to monitor for changes. Use `+` to include a branch. Use `-` exclude a branch. For the `branch name`, use the fully qualified name of the branch. For example, `refs/heads/<branch name>`. Use `` as a wildcard. This placeholder matches one or more characters in a string. For example, to include all feature branches, use: +:refs/heads/feature/ To monitor all branches, leave the input field empty. If the address that you entered as the Repository URL when you connected to GitLab points to a specific branch, this branch is automatically added to the list of monitored branches when you set up the connection.
Parse commits for issue comments	When enabled, specific segments of commit message text are copied to issues as comments. When you copy parts of the commit message to the issue as comments, you can trigger @mention notifications and expose information to users who don't have access to VCS changes. This setting does not affect how commit messages are shown in VCS changes. The entire commit message, including commands and issue comments, is always shown as part of the VCS change record in the activity stream. You should only enable this option when: You want to mention other users in your commit messages and generate notifications when the text is copied to an issue comment. You restrict the visibility for VCS changes and want to make commit-related information visible to external users as comments. To learn more about how YouTrack processes commit messages, see Apply Commands in VCS Commits.
VCS changes visibility	Restricts the visibility of VCS changes to one or more groups of users in YouTrack. When unrestricted, the list of VCS changes is visible to any user who has permission to read the issue.

Troubleshooting

Condition — References to issues in VCS commits are not shown as VCS changes in YouTrack.

Cause	Solution
The webhooks in the integrated VCS don't exist, are disabled, or are otherwise malformed.	Check the webhooks in the settings for your VCS repository. Make sure that the webhooks exist and that they are enabled. If you suspect that there is a problem with a webhook, delete or disable it in the settings for your VCS and set up a new VCS integration in YouTrack.

Condition — Commands that are specified in VCS commits are not applied to issues in YouTrack.

Cause	Solution
The users who commit changes to the repository are not members of the Committers group in the integration settings.	Either add the committers to the specified group in YouTrack or modify the selection in the integration settings.
The users who commit changes to the repository do not have permission to update issues in the connected project.	Either add these users to the project team or grant them a role in the project that includes the Read Issue and Update Issue permissions.
YouTrack can't find a user account that matches the author of the commit message.	The user must either use the same email address for their accounts in both YouTrack and GitLab or add the value that is stored as the Name in their GitLab profile to the list of VCS user names in their Hub accounts. For more information, see Match Change Authors and YouTrack Users.

Condition — You are unable to connect to your GitLab repository. Follow the instructions below to resolve the problem.

Cause	Solution
The user whose personal access token is used for authentication with GitLab does not have access to any projects in GitLab.	Access the Members settings for your GitLab project and add this user to the project. You can also share the project with a group where this user is a member. This user does not require a specific access level — Guest access is sufficient.

This user does not require a specific access level — Guest access is sufficient.

Condition — You are unable to establish a connection between YouTrack and your GitLab CE/EE server. See if any of the following causes are present.

Cause	Solution
The external service is unavailable.	Verify that your GitLab server is running.
The connection is blocked by a firewall.	Open the ports in the firewall that are used by YouTrack and the GitLab server.
The connection to the external service is blocked by the proxy server. You are trying to connect over the wrong port.	Set the system properties for your server that let YouTrack connect to other services through the proxy server. For instructions, see Proxy Configuration.
The GitLab server requires a secure connection.	Import the certificate for your GitLab server into YouTrack. For instructions, see SSL Certificates.
Your SSL certificate for the GitLab server has expired.	Renew and import the updated certificate into YouTrack. For instructions, see SSL Certificates.

Condition — You are unable to set up a connection to a repository on your GitLab CE/EE server and see an HTTP 422 Unprocessable Entity error in the logs. Follow the instructions below to diagnose and resolve the problem.

Cause	Solution
The base URL for your YouTrack server uses a non-default port. For example: `your.host:8080`	Open the Admin Area > Settings menu for your GitLab server and enable the Allow requests to the local network from hooks and services in the Outbound requests section of the page.
The base URL for your YouTrack server is either set to use `localhost` or a local subnet IP address. In this case, GitLab refuses to accept the request to create a webhook.	The best solution in this case update the base URL for your YouTrack installation to use a proper web address. Alternatively, you can use the Java start parameter `-Djetbrains.youtrack.webHooksBaseUrl=<base URL>` to specify the URL that is used to create webhooks. With this parameter, you don't have to update the base URL for your server. Instead, requests to create webhooks in external services use the specified alternative base URL. To learn how to set JVM options for your YouTrack installation, see Set JVM Options.
