<p>When you deploy applications on Kubernetes, you tell the master to start the application containers. The master schedules the containers to run on the cluster's nodes. <b>The nodes communicate with the master using the Kubernetes API</b>, which the master exposes. End users can also use the Kubernetes API directly to interact with the cluster.</p>

<p>A Kubernetes cluster can be deployed on either physical or virtual machines. To get started with Kubernetes development, you can use <a href="https://github.com/kubernetes/minikube">Minikube</a>. Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node. Minikube is available for Linux, Mac OS and Windows systems. The Minikube CLI provides basic bootstrapping operations for working with your cluster, including start, stop, status, and delete. For this bootcamp, however, you'll use a provided online terminal with Minikube pre-installed.</p>
