Pretty good platform for learning k8s. Nice UI, clear explanations. Of course my "inner QA engineer" came out and I had a few observations: * On the intro page about typing "kubectl delete ", autocomplete only worked for and I had to manually type * Whenever I clicked "Check" button after running a command to go to the next task, I would lose focus on the CLI window and would have to click back into the window. It wo…

Thank you for such a great feedback. Undo/redo - this is gonna be super-tricky to build, but we had similar ideas, mostly we were thinking about smth like redux'ish time travelling along the cluster state updates, slow-mo replays, things like that. But undo/repo over real cluster states is definitely an interesting idea.

Wow this is great! I've been meaning to play around with k8s and this looks to be a good first time experience with the subject.

I had a difficult time trying to figure out how to use the text editor to open a file and was stuck on a particular step for a bit. Would be nice to give users a quick intro on the basics of the UI.

Good luck!

Definitely a lot more work to be done to polish up the ux! Thanks for the compliments and thanks for pushing through the issues

Since I'm teaching Kubernetes I'll definitely take a deeper look into it. Recently I tried RedHat Labs, but unfortunately these resources were not lasting (only available for 2 months, which is not good if your students start the lab over the course of 6 months...)

Great! send me an email at mislav at and I'm happy to walk you through and discuss future plans

No worries!

Okay, honestly this is great. The content, flow, and ramp-up in complexity is wonderful.

Please, please, please add a way to resume your learning session without starting over from scratch. I didn't click on "Start next class" once and was booted out to the main menu. There seems to be no way to resume my "next class" without restarting the entire module. Once you have this, I'll be a paying customer.

We have this on the roadmap, but it's not as trivial as it seems, since there's a real cluster behind and it's very opinionated

what are differences between msb and katacoda?

We think katacoda is great! I'd say our two major differences are the interactive visual layer representing the real time state of the system, as well as having much more advanced content. Our main content developer is Nigel Poulton, the author of The Kuberentes book, and our goal is to cover the whole of k8s in the next few months

I did pop over and take a look at katacoda (which is also a pretty cool platform I didn't know about before, thanks for the tip!). Walking thru the first couple steps of their getting started with k8s, if I hadn't already been thru what I'd done on MSB theirs would have been a lot more confusing :)

I totally agree that the interactive visual layer was a huge bonus for my understanding, and the ordering and transparency of what the commands do in the intro lesson on MSB was a lot better. That said, katacoda seems to have a much broader focus on many more technologies.

Our hypothesis is that we should go super deep and focus on one technology before thinking about something else, and this is the mistake that other vendors are doing. We see msb doing deep dives in things like relational databases, elasticsearch and rxjs in the future, but doing it properly one step at a time
