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.

WOW. Okay, this is really, really cool and is exactly my niche, as you mentioned it's kinda a combination of things like Stylus/uBlock Origin filters and custom filters/etc. This is really needed, as for example GitHub code preview is completely and utterly fucked, to put it lightly. Showing symbols, not being able to select code properly without weird visual glitches happening..... Requires a bunch of scripts to... - Source: Hacker News / 9 months ago
