Jenkins: The Automation Server for CI/CD

The open-source automation server that taught a generation of teams to build, test, and ship on every commit.
Welcome to Jenkins: The Automation Server for CI/CD.
Jenkins is the leading open-source automation server, the long-running engine behind continuous integration and continuous delivery for an enormous swath of the software industry. It began as Hudson at Sun Microsystems in 2004, was forked into Jenkins in 2011, and today is governed openly under the Continuous Delivery Foundation, part of the Linux Foundation, where it became the first project to graduate. This book is a tour of how Jenkins actually works. It opens with the problem Jenkins solves and the controller-and-agent architecture that lets one server orchestrate work across many machines. From there it walks through jobs, contrasting classic freestyle projects with modern pipelines, and then dives into Pipeline as code: the Jenkinsfile, the declarative and scripted styles, and the stages, steps, and post conditions that shape a build. Later chapters cover distributed builds and agents, credentials and secret handling, the vast plugin ecosystem alongside Blue Ocean and shared libraries, and running Jenkins on Kubernetes. A closing chapter gathers the practices that keep a Jenkins installation healthy as it grows.
