Set-up a Kubernetes cluster in minutes

If you would like to set-up your own low budget Kubernetes cluster, do it as I did, with Rancher’s K3s.

We wanted an installation of Kubernetes that was half the size in terms of memory footprint. Kubernetes is a 10-letter word stylized as K8s. So something half as big as Kubernetes would be a 5-letter word stylized as K3s. There is no long form of K3s and no official pronunciation.
