Kubernetes' command-line tool, kubectl, is used to manage a cluster and applications running inside it. We'll use kubectl a lot throughout the book, so we won't go into details just yet. Instead, we'll discuss its commands through examples that will follow shortly. For now, think of it as your interlocutor with a Kubernetes cluster.
Let's install kubectl.
All the commands from this chapter are available in the 02-minikube.sh (https://gist.github.com/vfarcic/77ca05f4d16125b5a5a5dc30a1ade7fc) Gist.
Feel free to skip the installation steps if you already have kubectl. Just make sure that it is version 1.8 or above.
If you are a MacOS user, please execute the commands that follows:
