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.

Running Containers with Java Applications

In Chapter 5, Creating Images with Java Applications, we learned about the structure of a Dockerfile and how to build our images. At this point, you should be able to create your own Docker image and start using it. Actually, we did run the containers several times, but without getting much into details. We built the image manually, using a Dockerfile, and then issuing a docker build command. We have also been using Maven to automate the build process. The image we have created contains our simple REST Java service. We've already been running it for the purpose of checking if it really works. This time, however, we are going into some more detail about running the containers from our images. This chapter will include the following concepts:

  • Starting and stopping containers
  • Container running modes
  • Monitoring containers
  • Container restart...
