In this first volume, you will understand the key concepts of CI, as well Continuous Deployment. Next, we get started with Jenkins by installing and configuring a Master and Node server. Once this is done, you will understand the main parts of Jenkins and create different types of Jenkins projects to automate everything that you want. We finish the section by looking at a Java web project and creating the necessary steps to build and test it, thereby empowering you to implement it in a real project. Then you will understand the key concepts of DevOps and delve into Jenkins Pipeline, a set of plugins that provides a toolkit for designing simple-to-complex delivery pipelines as code. To design a production-ready delivery pipeline, you will start by creating a simple pipeline and understanding Jenkins Pipeline terms and its particularities. Next, you will set up Docker to create isolated build environments.
