In Chapter 7, Introduction to Kubernetes, we learned about the Kubernetes architecture and concepts. We know about nodes, Pods, and services. In this chapter, we will do some practical hands-on and deploy our Java REST service to a local Kubernetes cluster. For learning purposes, we will use the Minikube tool to create a cluster on the local machine. It's easier to learn Kubernetes on a local machine instead of going to the cloud in the first place. Because Minikube runs locally, instead of through a cloud provider, certain provider-specific features such as load balancers and persistent volumes, will not work out of the box. However, you can use NodePort, HostPath, persistent volumes and several addons such as DNS, or dashboard to test your apps locally before pushing to a real, production-grade cluster. In Chapter 10, Deploying Java on Kubernetes...

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.
