 This tutorial walks you through setting up Kubernetes the hard way. It is not for someone looking for a fully automated tool to set up a Kubernetes cluster. Kubernetes The Hard Way is designed for learning, so it means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.

 In this lab, you will set up one of the four machines as a `jumpbox`. You will use this machine to run commands in this tutorial. While a dedicated machine is used to ensure consistency, you can run these commands from just about any machine, including your personal workstation running macOS or Linux.
 
 Think of the `jumpbox` as the administration machine you will use as a home base when setting up your Kubernetes cluster from the ground up. One thing you need to do before you get started is to install a few command line utilities and clone the Kubernetes The Hard Way git repository, which contains some additional configuration files that you will use to configure various Kubernetes components throughout this tutorial.
