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.

We are not going to implement authentication and security features, just to make it as clean and simple as possible. Books will be stored in an in-memory relational H2 database. We are going to build and run our bookstore with Maven, so let's begin with the pom.xml build file.

Maven build file

As you will see, the parent project for our own service is spring-boot-starter-parent. Spring this is the parent project providing dependency and plugin...
