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.

Adding Jenkins slaves – Docker containers

In the following section, we will learn how to install and configure the Docker plugin that will allow us to spawn on-demand Jenkins slaves (Docker containers) from a CI pipeline. The Docker containers are started by the CI pipeline, and once the build is done, they are destroyed. In the following section, we will only see the configuration part. It is in the next chapter that we will see this process in action.

Prerequisites

Before we begin, make sure you have the following things ready:

  • A Jenkins server running on any of the following platforms: Docker, standalone, cloud, VM, servlet container, and so on. (refer to Chapter 2, Installing Jenkins).
  • Your Jenkins server should have access to the internet. This is necessary to download and install plugins.
  • Your Jenkins server can talk to GitHub using the GitHub plugin. (Refer to the Add GitHub credentials inside Jenkins and Configure Webhooks on GitHub from Jenkins sections from Chapter 3, The New Jenkins...
