gitlab-plugin

This plugin emulates Jenkins as a GitlabCI Web Service to be used with GitlabHQ.

Help Needed

  • We are seeking help to maintain and improve this plugin. This includes keeping up a Changelog, releasing builds, reviewing merge requests, etc. If you are interested, please post to the Jenkins Developers list (https://groups.google.com/forum/#!forum/jenkinsci-dev) or ping autojack (@omehegan on Github) in #jenkins on irc.freenode.org IRC and ask for commit access.

Supported GitLab versions

  • 7.14.x

Unsupported GitLab versions

  • 8.0.x - in this version, GitLab folded the GitLabCI functionality into core GitLab, and in doing so broke the ability for the plugin to give build status to GitLab. Jenkins build status will never work with GitLab 8.0.x!
  • 8.1.x - in this version, GitLab created a new public API to interface with external CI services like Jenkins. This plugin will be updated to support the new API; that work is incomplete at this time. See https://github.com/jenkinsci/gitlab-plugin/pull/127 for status.

Current Supported GitLabCI Functions

  • /project/PROJECT_NAME/builds/COMMIT_SHA1/status.json (used for Merge Request pages) returns build result for Merge Request build with COMMIT_SHA1 as last commit
  • /project/PROJECT_NAME/builds/status.png?ref=BRANCH_NAME returns build status icon for latest build for BRANCH_NAME
  • /project/PROJECT_NAME/builds/status.png?sha1=COMMIT_SHA1 returns build status icon for latest build for COMMIT_SHA1 as last commit
  • /project/PROJECT_NAME/builds/COMMIT_SHA1 redirects to build page of the last build containing COMMIT_SHA1 as last commit
  • /project/PROJECT_NAME/commits/COMMIT_SHA1 redirects to build page of the last build containing COMMIT_SHA1 as last commit
  • /project/PROJECT_NAME?ref=BRANCH_NAME redirects to build page of the last build for BRANCH_NAME
  • /project/PROJECT_NAME triggers a build, type (Merge Request or Push) depending on payload

Configuring access to Gitlab

Optionally, the plugin communicates with the Gitlab server in order to fetch additional information. At this moment, this information is limited to fetching the source project of a Merge Request, in order to support merging from forked repositories.

To enable this functionality, a user should be set up on Gitlab, with adequate permissions to access the repository. On the global configuration screen, supply the gitlab host url http://your.gitlab.server and the API token of the user of choice.

Using it With A Job

  • Create a new job by going to New Job
  • Set the Project Name to whatever you like
  • In the Source Code Management section:
    • Click Git
    • Enter your Repository URL (e.g.: git@your.gitlab.server:group/repo_name.git)
      • In the Advanced settings, set its Name to origin
    • To be able to merge from forked repositories:
      Note: this requires configuring communication to the Gitlab server
      • Add a second repository with:
        • URL: ${gitlabSourceRepoURL}
        • Name (in Advanced): ${gitlabSourceRepoName}
    • In Branch Specifier enter:
      • For single-repository setups: origin/${gitlabSourceBranch}
      • For forked repository setups: ${gitlabSourceRepoName}/${gitlabSourceBranch}
    • In Additional Behaviours:
      • Click the Add drop-down button.
      • Select Merge before build from the drop-down.
      • Set *Name of the repository" to origin
      • Set Branch to merge as ${gitlabTargetBranch}
  • In the Build Triggers section:
    • Check the Build when a change is pushed to GitLab.
    • Use the check boxes to trigger builds on Push and/or Merge Request events
    • Optionally enable building open merge requests again after a push to the source branch.
  • Configure any other pre build, build or post build actions as necessary
  • Click Save to preserve your changes in Jenkins.

GitLab Configuration (≥ 8.0)

  • In GitLab go to you primary repository's project Settings
    • Click on Web Hooks
      • Add a Web Hook for Merge Request Events and Push Events to http://JENKINS_URL/project/PROJECT_NAME

If you plan to use forked repositories, you will need to enable the GitLab CI integration on each fork.

  • Go to the Settings page in each developer's fork
  • Click on Services
    • Click on Web Hooks
      • Add a Web Hook for Merge Request Events and Push Events to http://JENKINS_URL/project/PROJECT_NAME
        Note: You do not need to select any "Trigger Events" as the Web Hook for Merge Request Events will alert Jenkins.

GitLab Configuration (≥ 8.1)

GitLab 8.1 uses the same configuration as GitLab 8.0

  • GitLab 8.1 has implemented a commit status api. To enable this check the Use GitLab CI features under the project settings.

GitLab Configuration (< 8.0)

  • In GitLab go to you primary repository's project Settings
    • Click on Services
    • Click on GitLab CI
      • Check the Active checkbox
      • For Token put any random string (This is not yet functioning)
      • For Project URL put http://JENKINS_URL/project/PROJECT_NAME
      • Click Save
    • Click on Web Hooks
      • Add a Web Hook for Merge Request Events to http://JENKINS_URL/project/PROJECT_NAME
        Note: GitLab for some reason does not send a merge request event with the GitLab Service.

If you plan to use forked repositories, you will need to enable the GitLab CI integration on each fork.

  • Go to the Settings page in each developer's fork
  • Click on Services
    • Click on GitLab CI
      • Check the Active checkbox
      • For Token put any random string (This is not yet functioning)
      • For Project URL put http://JENKINS_URL/project/PROJECT_NAME
      • Click Save
        Note: You do not need to select any "Trigger Events" as the Web Hook for Merge Request Events will alert Jenkins.

Branch filtering

Triggers from push events may be filtered based on the branch name, i.e. the build will only be allowed for selected branches. On the project configuration page, a list of all branches on the remote repository is displayed under Build when a change is pushed to GitLab.. It is possible to select multiple branches by holding Ctrl and clicking.

This functionality requires accessing the Gitlab server (see above) and for the time being also a git repository url already saved in the project configuration. In other words, when creating a new project, the configuration needs to be saved once before being able to select the allowed branches. For Workflow jobs, the configuration must be saved and the job must be run once before the list is populated. For existing projects, all branches are allowed to push by default.

Build Tags

In order to build when a new tag is pushed:

  • In the GitLab server add Tag push events to the Web Hook
  • In the Jenkins under the Source Code Management section:
    • select Advance... and add +refs/tags/*:refs/remotes/origin/tags/* as Refspec
    • you can also use Branch Specifier to specify which tag need to be built (exampple refs/tags/${TAGNAME})

Parameterized builds

You can trigger a job a manually by clicking This build is parameterized and adding the relevant build parameters. These include:

  • gitlabSourceBranch
  • gitlabTargetBranch
  • gitlabSourceRepoURL
  • gitlabSourceRepoName
  • gitlabBranch (This is optional and can be used in shell scripts for the branch being built by the push request)
  • gitlabActionType (This is optional and can be used in shell scripts or other plugins to change the build behaviour. Possible values are PUSH or MERGE)

Help Needed

  • /projects/ - seems to be already used by Jenkins, A way to use this path would be awesome
  • ?token=XYZ - Can not find a way to include a token parameter on an AbstractProject to security check without an extra plugin configuration
  • /PROJECT_NAME/ should really be /PROJECT_ID_NUMBER/ - Can not find a project id number on an AbstractProject to use here instead.
