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.

It's surely both. Look at the newest questions: https://stackoverflow.com/questions?tab=Newest Most questions have negative karma. Even if somehow that is "deserved", that's not a healthy ecosystem. All that is left of SI are clueless questioners and bitter, jaded responders. SO worked when "everyone" was new to it, and they felt energized to ask questions ( even "basic" questions, because they hadn't been asked... - Source: Hacker News / 7 months ago
