JenkinsGitLab

JenkinsGitLab refers to the integration between Jenkins, an open source automation server, and GitLab, a web-based Git repository manager. The integration enables continuous integration and continuous delivery workflows that respond to events in GitLab and report results back to GitLab.

The core component is the GitLab Plugin for Jenkins, which provides a bridge between the two systems. It allows Jenkins jobs to be triggered by GitLab events such as pushs, merge requests, or tag creations, and lets Jenkins publish build statuses and test results back to GitLab. The integration typically uses GitLab webhooks or service hooks to notify Jenkins, and authentication is established via a GitLab personal access token or OAuth credentials.

Typical workflow involves configuring a GitLab project to notify Jenkins on relevant events. In Jenkins, the GitLab plugin is installed, and a pipeline or freestyle job is created that checks out code from GitLab and defines the build steps. Upon completion, Jenkins updates the corresponding commit or merge request status in GitLab to reflect success, failure, or other states, helping developers track build health and gate merges.

Use cases include gating merges with CI checks, automating deployments, and coordinating complex pipelines that span multiple stages or environments. The JenkinsGitLab setup is adaptable for self-hosted GitLab instances or GitLab.com, and it requires ongoing maintenance to stay compatible with evolving Jenkins and GitLab versions.
