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.

Installing Docker

Docker's installation process is quick and simple. Currently, it's supported on most Linux operating systems, and a wide range of them have dedicated binaries provided. macOS and Windows are also well supported with native applications. However, it's important to understand that Docker is internally based on the Linux kernel and its specifics, and this is why, in the case of macOS and Windows, it uses VMs (HyperKit for macOS and Hyper-V for Windows) to run the Docker Engine environment.

Prerequisites for Docker

The Docker Community Edition requirements are specific for each operating system, as outlined here:

  • macOS:
    • macOS 10.15 or newer
    • At least 4 GB of RAM
    • No VirtualBox prior to version 4.3.30 installed
  • Windows:
    • 64-bit Windows 10/11
    • The Hyper-V package enabled
    • At least 4 GB of RAM
  • Linux:
    • 64-bit architecture
    • Linux kernel 3.10 or later

If your machine does not meet these requirements, the solution is...
