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.

Alternative cluster management systems

Kubernetes is not the only system that can be used to cluster Docker containers. Even though it's currently the most popular one, there may be some valid reasons to use different software. Let's walk through the alternatives.

Docker Swarm

Docker Swarm is a native clustering system for Docker that turns a set of Docker hosts into one consistent cluster, called a swarm. Each host connected to the swarm plays the role of a manager or a worker (there must be at least one manager in a cluster). Technically, the physical location of the machines does not matter; however, it's reasonable to have all Docker hosts inside one local network; otherwise, managing operations (or reaching a consensus between multiple managers) can take a significant amount of time.

Information

Since Docker 1.12, Docker Swarm is natively integrated into Docker Engine in swarm mode. In older versions, it was necessary to run the swarm container on each...
