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.

I can access the 'playground' exercise, but you have to sign up to the site to access the other tutorials.

True, but it's a free signup and we don't send unwanted emails...

I can understand why you'd want to do this, but it would be great if it was optional.

I'd love to hear your feedback, bug reports are always welcome. We haven't heard of other problems.

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.
