# Set Up The Jumpbox
In this lab you will set up one of the four machines to be a `jumpbox`. This machine will be used to run commands in this tutorial. While a dedicated machine is being used to ensure consistency, these commands can also be run from just about any machine including your personal workstation running macOS or Linux.

Think of the `jumpbox` as the administration machine that you will use as a home base when setting up your Kubernetes cluster from the ground up. One thing we need to do before we get started is install a few command line utilities and clone the Kubernetes The Hard Way git repository, which contains some additional configuration files that will be used to configure various Kubernetes components throughout this tutorial.
