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.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The Dockerfile is used to create the image when you run the docker build command." A block of code is set as follows:

"apiVersion": "v1",
"kind": "Pod",
"name": ”rest_service”,
"labels": {
"name": "rest_service"
"spec": {
"containers": [{
"name": "rest_service",
"image": "rest_service",
"ports": [{"containerPort": 8080}],

Any command-line input or output is written as follows:

docker rm $(docker ps -a -q -f status=exited)

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Clicking the Skip For Now will take you to the the images list without logging into the Docker Hub."

Warnings or important notes appear in a box like this.
Tips and tricks appear like this.
