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 took a look at the clustering methods for Docker environments that allow you to set up complete staging and production environments. Let's go over some of the key takeaways from this chapter:

  • Clustering is a method of configuring a set of machines in a way that, in many respects, can be viewed as a single system.
  • Kubernetes is the most popular clustering system for Docker.
  • Kubernetes consists of the Kubernetes server and the Kubernetes client (kubectl).
  • The Kubernetes server can be installed locally (through minikube or Docker Desktop), on the cloud platform (AKS, GKE, or EKS), or manually on a group of servers. Kubernetes uses YAML configurations to deploy applications.
  • Kubernetes provides features such as scaling and rolling updates out of the box.
  • Kubernetes provides DNS resolution, which can help when you're deploying systems that consist of multiple dependent applications.
  • The most popular clustering systems...
