If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

This book guides you through the process of creating CI and CD pipelines for a container-based, modular, three-tier “Hello World” web application. Once you’ve mastered the concepts and techniques presented, I encourage you to apply your knowledge to a more complex software project. Delve deeper into the intricacies of each DevOps tool’s configuration within the CI and CD platform. Explore the possibilities of configuring Jenkins entirely using JCasC. On the testing front, challenge yourself by integrating more advanced testing methods into your workflow.
