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.

Summary

In this chapter, we covered the Jenkins environment and its configuration. The knowledge we have gained is sufficient to set up the complete Docker-based Jenkins infrastructure. The key takeaway points from the chapter are as follows:

  • Jenkins is a general-purpose automation tool that can be used with any language or framework.
  • Jenkins is highly extensible by plugins, which can be written or found on the internet.
  • Jenkins is written in Java, so it can be installed on any operating system. It's also officially delivered as a Docker image.
  • Jenkins can be scaled using the master-agent architecture. The master instances can be scaled horizontally or vertically, depending on an organization's needs.
  • Jenkins agents can be implemented with the use of Docker, which helps in automatic configuration and dynamic agent allocation.
  • Custom Docker images can be created for both the Jenkins master and Jenkins agent.
  • Jenkins is highly configurable, and...
