As you remember from the previous chapters, Docker utilizes the concept of containerization. You simply put your application (in this context, the application will be a microservice) no matter what language and technology it uses, into a single, deployable and runnable piece of software, called the image. We are going to cover the process of packaging a Java application into the image in detail in the Chapter 4, Creating Java Microservices. The Docker image will contain everything our service needs to work, it can be a Java Virtual Machine with all required libraries and an application server, or it can also be a node.js application packaged together with the node.js runtime with all the needed node.js modules, such as express.js or whatever the node.js service needs to run. A microservice might consist of two containers, one running the service...

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.
