Most people know that killer.sh is where you train for the CKAD, CKA, and CKS certifications and that you get two free attempts for each cert that you sign up for, but most might not know that there is a lot to learn just in their GitHub repos without using killer.sh at all. For example, they have a POSIX shell script that sets up an environment for use with Kubernetes and very clearly outlines the steps to take an Ubuntu server to a fully functional Kubernetes cluster. Just reading the scripts is very instructive.
