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.

Starting and stopping containers

Let's go back a little and begin with the basics: how to run and stop the Docker container manually, from the shell or the command line.


As you have seen in the previous chapters, to spin-up the container from the image, we use the docker run command. The running container will have its own file system, networking stack, and isolated process tree separate from the host. As you will remember from Chapter 5, Creating Images with Java Applications, every single docker run command creates a new container and executes a command specified in the Dockerfile, CMD, or ENTRYPOINT.

The syntax of the docker run command is as follows:
