Continuous Delivery with Docker and Jenkins, 3rd Edition - Third Edition

By: Rafał Leszko

Overview of this book

This updated third edition of Continuous Delivery with Docker and Jenkins will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of app development. You’ll start by setting up a Docker server and configuring Jenkins on it. Next, you’ll discover steps for building applications and microservices on Dockerfiles and integrating them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, configuration management, and Infrastructure as Code. Moving ahead, you'll learn how to ensure quick application deployment with Docker containers, along with scaling Jenkins using Kubernetes. Later, you’ll explore how to deploy applications using Docker images and test them with Jenkins. Toward the concluding chapters, the book will focus on missing parts of the CD pipeline, such as the environments and infrastructure, application versioning, and non-functional testing. By the end of this continuous integration and continuous delivery book, you’ll have gained the skills you need to enhance the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Chapter 3: Configuring Jenkins

To start any continuous delivery process, we need an automation server such as Jenkins. However, configuring Jenkins can be difficult, especially when the amount of tasks assigned to it increases over time. What's more, since Docker allows the dynamic provisioning of Jenkins agents, is it worth spending time to configure everything correctly upfront, with scalability in mind?

In this chapter, we'll present Jenkins, which can be used separately or together with Docker. We will show that the combination of these two tools produces surprisingly good results – automated configuration and flexible scalability.

This chapter will cover the following topics:

  • What is Jenkins?
  • Installing Jenkins
  • Jenkins – Hello World
  • Jenkins architecture
  • Configuring agents
  • Custom Jenkins images
  • Configuration and management
