Imagine creating and testing Java EE applications on Apache Tomcat or Wildfly in minutes, along with deploying and managing Java applications swiftly. Sounds too good to be true? You have a reason to cheer, because such scenarios are 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 be then introduced to the concept of microservices and learn how to deploy and run Java microservices as Docker containers. Moving on, the book will focus on Kubernetes and its features. You will start by running the local cluster using Minikube. The next step will be to deploy your Java service in the real cloud, on Kubernetes running on top of Amazon AWS. At the end of the book, you will get hands-on experience of some more advanced topics to further extend your knowledge of Docker and Kubernetes.

, Introduction to Docker, introduces the reasoning behind Docker and presents the differences between Docker and traditional virtualization. The chapter also explains basic Docker concepts, such as images, containers, and Dockerfiles.

, Networking and Persistent Storage, explains how networking and persistent storage work in Docker containers.

, Working with Microservices, presents an overview of what microservices are and explains their advantages in comparison to monolithic architectures.
