I wanted to learn Kubernetes, but the options were either "build a local lab" or pay for expensive classes built around cloud environments. I wanted something you could just open and learn from. So I built a browser-based cluster simulation with lessons to follow along.
It behaves like Kubernetes, but it's just JavaScript under the hood. Enough to run kubectl commands, create resources, and watch their lifecycle play out. There's also a live cluster visualizer so you can see your nodes, Pods, and containers in real time.
Once you've covered the concepts, you can jump into CKA drills. Each drill is a standalone, time-boxed scenario that mirrors the real exam format: a broken cluster state, a concrete task, and a pass-or-fail outcome.
The goal isn't to simulate the exam. It's to build the reflex of diagnosing and fixing things quickly, so that when you sit the real exam, the commands and the reasoning are already automatic.

I would recommend that people stop taking this kind of bait, especially as an organization. Discord is free for now but that's bound to change and you can't have any expectation of privacy there. In my eyes they're practically the poster child for an organization who could (and arguably should) be running their own solution on their own servers.

I like Matrix but unfortunately it has major stability issues. The GrapheneOS project moved most of their chat over to Discord after their Matrix community got nuked twice. They still maintain a Matrix community which is bridged to their Discord instance, but most users are on the Discord side of the fence. IMHO, Revolt is a better FOSS Discord alternative: https://revolt.chat/. Relatively young project, but they... - Source: Hacker News / about 1 year ago
Really makes you wonder if/when Discord goes IPO, that Meta would buy a controlling stake in it? Fortunately there are open source alternatives even if they aren't as popular as Discord at the moment, such as Revolt Chat: https://revolt.chat/ I miss the days of self-hosted forums; sadly it seems that algorithms, and the need to satisfy the need for 'instant' connection/information are ruining forums for young... - Source: Hacker News / over 1 year ago

I work on Revolt[1], which is an open-source chat platform very similar to Discord. I wonder if we should expect another huge influx soon... [1]: https://revolt.chat. - Source: Hacker News / over 1 year ago
