Lab 3.1 kubeadm-config.yaml

In going through the lab we're told to write out the yaml configuration. Is there a way to generate this as a skeleton, or how to be know what options to be putting here based on the official docs?

I'm aware that in the CKA exam I won't be able to just copy this from coursework. Trying to memorise it can work, but if there's a better way it'd be good to know.
