Docker and Kubernetes for Java Developers

Overview of this book

Imagine creating and testing Java EE applications on Apache Tomcat Server or Wildfly Application server in minutes along with deploying and managing Java applications swiftly. Sounds too good to be true? But you have a reason to cheer as such scenarios are only possible by leveraging Docker and Kubernetes. This book will start by introducing Docker and delve deep into its networking and persistent storage concepts. You will then proceed to learn how to refactor monolith application into separate services by building an application and then packaging it into Docker containers. Next, you will create an image containing Java Enterprise Application and later run it using Docker. Moving on, the book will focus on Kubernetes and its features and you will learn to deploy a Java application to Kubernetes using Maven and monitor a Java application in production. By the end of the book, you will get hands-on with some more advanced topics to further extend your knowledge about Docker and Kubernetes.

Introduction to Kubernetes

After reading Chapter 6, Running Containers with Java Applications, you now have a lot of knowledge about using Docker to package your Java applications. It's now time to move even further and focus on what we are missing--the container management and orchestration. There are some suitable tools on the market, such as Nomad, Docker Swarm, Apache Mesos, or AZK, for example. In this chapter, we will focus on probably the most popular one, Kubernetes. Kubernetes (sometimes referred to as k8s) is an open source orchestration system for Docker containers, created by Google in 2015. The first unified container management system developed at Google was the system, internally called, Borg; Kubernetes is its descendant. The list of topics covered in this chapter will be:

  • Why and when we need container management
  • An introduction to Kubernetes
  • Basic Kubernetes...
