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.

In the past, we used to create applications as complete, massive, and uniform pieces of code. Let's take a web MVC application for example. A simplified architecture of such an application is presented in the following diagram:

As you can see, the diagram presents the typical web application, a fragment of a banking system in this case. It's the Model View Controller (MVC) application, consisting of models, views, and controllers to serve up HTML content back to the client's browser. It could probably also accept and send the JSON...
