Overview of this book

In past few years, agile software development has seen tremendous growth. There is a huge demand for software delivery solutions that are fast yet flexible to numerous amendments. As a result, Continuous Integration (CI) and Continuous Delivery (CD) methodologies are gaining popularity. This book starts off by explaining the concepts of CI and its significance in the Agile. Next, you'll learn how to configure and set up Jenkins in many different ways. The book exploits the concept of "pipeline as code" and various other features introduced in the Jenkins 2.x release to their full potential. We also talk in detail about the new Jenkins Blue Ocean interface and the features that help to quickly and easily create a CI pipeline. Then we dive into the various features offered by Jenkins one by one, exploiting them for CI and CD. Jenkins' core functionality and flexibility allows it to fit in a variety of environments and can help streamline the development process for all stakeholders. Next, you'll be introduced to CD and will learn how to achieve it using Jenkins. Through this book's wealth of best practices and real-world tips, you'll discover how easy it is to implement CI and CD using Jenkins.

In this section, we will learn about the multibranch pipeline job in Jenkins. This is one of the new features added to Jenkins release 2.x.

A Multibranch pipeline works using a Jenkinsfile that is stored along with your source code inside a version control repository. A Jenkinsfile is nothing but a pipeline script that defines your CI pipeline:

In addition to that, the Multibranch pipeline is designed to trigger a build whenever there is a new code change on any of the branches on your Git/GitHub repository. This is depicted in the following screenshot:
