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.

Working with Microservices

After reading the previous two chapters, you should now have an understanding of the Docker architecture and its concepts. Before we go further on our Java, Docker, and Kubernetes journey, let's get to know the concept of microservices.

By reading this chapter, you will find out why a transition to microservices and cloud development is necessary and why monolithic architecture is not an option anymore. The microservices architecture is also where Docker and Kubernetes will be especially useful.

This chapter will cover the following topics:

  • An introduction to microservices and comparison to a monolithic architecture
  • How Docker and Kubernetes fits into the microservices world
  • When to use microservices architecture

Before we actually create the Java microservice and deploy it using Docker and Kubernetes, let's start with an explanation of the...
