Creating a cluster

We'll go through almost the same routine as we did in the previous chapters. We'll enter the directory where we cloned the vfarcic/k8s-specs repository, pull the latest code, start a Minikube cluster, and so on and so forth. The only new thing we'll do this time is to enable one more addon. We'll add Heapster to the cluster. It's too soon to explain what it does and why we'll need it. That will come later. For now, just remember that there will soon be something in your cluster called Heapster. If you do not already know what it is, consider this a teaser meant to build suspense.

All the commands from this chapter are available in the 13-resource.sh (https://gist.github.com/vfarcic/cc8c44e1e84446dccde3d377c131a5cd) Gist.
