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 chapter we have learned how to manage the container's life, start it using different run modes (foreground and detached), stop or remove it. We also know how to create constraints to make our containers run exactly how we want them to, by limiting the CPU and RAM usage using runtime constraints. Having our containers running, we are now able to inspect the container's behavior in numerous ways, it will be reading log output, looking at events or browsing the statistics. If you are using Maven, and as the Java developer you probably are, you can now configure the Docker Maven plugin to start or stop containers for you automatically.

We know a lot about Docker already, we can build and run images. It's time to go further. We are going automate deployment, scaling, and management of containerized applications using Kubernetes. And this is the moment...
