Continuous Delivery with Docker and Jenkins - Second Edition

By: Rafał Leszko

Overview of this book

Continuous Delivery with Docker and Jenkins, Second Edition will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of an app development. It will start with setting up a Docker server and configuring Jenkins on it. It will then provide steps to build applications on Docker files and integrate them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, and configuration management. Moving on, you will learn how to ensure quick application deployment with Docker containers along with scaling Jenkins using Kubernetes. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. Towards the end, the book will touch base with missing parts of the CD pipeline, which are the environments and infrastructure, application versioning, and nonfunctional testing. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Chapter 3. Configuring Jenkins

To start with any Continuous Delivery process, we need an automation server like Jenkins. Configuring Jenkins can be however difficult, especially when the amount of tasks assigned to it increases over time. What's more, since Docker allows dynamic provisioning of Jenkins agents, it's worth to spend some time to configure everything correctly upfront, with the 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?
  • Jenkins installation
  • Jenkins Hello World
  • Jenkins architecture
  • Configuring agents
  • Custom Jenkins images
  • Configuration and management
