Jenkins makes the most sense once you understand what it is for. Continuous integration and continuous delivery are disciplines, and Jenkins is one machine that automates them. Learn the tool before the practice and you end up with brittle jobs that automate a bad process faster. Order matters.
This path deliberately front-loads the principles, then moves to Jenkins itself, then to writing pipelines as code, and closes with the organizational culture that makes it all stick.
Learn the practice before the tool
Start with Continuous integration, the foundational text on integrating early and often to keep a codebase healthy. Then read Continuous Delivery, the influential book that extends the idea all the way to reliable, repeatable releases. With those principles in hand, you will understand why Jenkins is shaped the way it is.
Learn Jenkins and pipelines as code
Now turn to Jenkins for a solid grounding in the server, jobs, and plugins, and Learning Continuous Integration with Jenkins to see a full CI setup assembled step by step. Modern Jenkins is defined in code, so Pipeline As Code teaches you to version your build and deploy logic alongside your app, and Hands-On Continuous Integration and Delivery walks complete pipelines from commit to production.
Make it cultural and portable
Automation only pays off when the organization changes with it, so The DevOps handbook covers the practices, flow, and feedback loops that make CI/CD deliver. And because pipelines increasingly build and ship containers, Docker : up and Running gives you the container fundamentals that modern Jenkins pipelines assume.
Read in this order and Jenkins becomes the reliable backbone of a healthy delivery process rather than a pile of fragile jobs. Follow the full path to keep the books sequenced.
