Using Kubernetes with Java

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...
