Can you elaborate? It worked for me (as in was both functional and educational) - was it the function or the education that didn't work for you?
I've also found Katacoda a good platform for Tensorflow tutorials (e.g. https://katacoda.com/basiafusinska/scenarios/tensorflow) - not great for power users, but awesome for people who just want to learn the basics without having to set anything up.
Sure, sorry I didn't elaborate my previous comment, it was late here and after re-reading, it feels like a rant. What I meant was that I've tried following Katacoda's kubeadm tutorial (https://www.katacoda.com/courses/kubernetes/getting-started-...) but for some reason it seems not to be working for me. Both cluster nodes never get `ready` after finishing the tutorial, only the master one.
