- Jenkins CI (deprecated) service
- Trigger Jenkins build after push to repo
- Show build status on Merge Request page
- Jenkins GitLab Hook plugin
- git clone access for Jenkins from GitLab repo (via ssh key)
- Install GitLab Hook plugin
- Setup jenkins project
In GitLab, perform the following steps.
Jenkins needs read access to the GitLab repository. We already specified a private key to use in Jenkins, now we need to add a public one to the GitLab project. For that case we will need a Deploy key. Read the documentation on how to setup a Deploy key.
Now navigate to GitLab services page and activate Jenkins
Done! Now when you push to GitLab - it will create a build for Jenkins. And also you will be able to see merge request build status with a link to the Jenkins build.
The GitLab Hook plugin in Jenkins supports the automatic creation of a project for each feature branch. After configuration GitLab will trigger feature branch builds and a corresponding project will be created in Jenkins.
Configure the GitLab Hook plugin in Jenkins. Go to 'Manage Jenkins' and then 'Configure System'. Find the 'GitLab Web Hook' section and configure as shown below.
