What Jenkins is

Jenkins is a free, open-source automation server for continuous integration and continuous delivery. Teams can use it for a basic CI service or make it a hub for a project’s delivery work. Its Pipeline feature represents workflows as code, usually in a Jenkinsfile kept in source control. Pipelines can continue through controller restarts, pause for human input, and run tasks in parallel. Jenkins can spread builds, tests, and deployments across multiple machines and platforms. Its Plugin Index lists more than 2,000 community-contributed extensions for building, deploying, and automating projects; the project says these connect with practically every tool in the CI/CD toolchain. A web interface supports setup and configuration, with error checks and built-in help. Jenkins is available as WAR files, native packages, installers, and Docker images, with guides for public-cloud deployment. Users can choose stable LTS releases every four weeks or a weekly release line. The project publishes security advisories, but does not guarantee timely fixes for every plugin vulnerability and reports delays in processing security submissions.
