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 launched an Ubuntu playground on Killercoda, which gave me access to a Linux terminal environment. - Source: dev.to / 9 months ago
Killercoda offers free environments (based on Ubuntu) with various tools for beginners to try hands-on. It also has the Kubernetes playground which provides control plane server access for 1 hour. In which we can try to practice hands-on with control plane components. Because sometimes we are dependent on training platforms to try the control plane (or kubeadm) practice, and killercoda comes handy as a free... - Source: dev.to / about 3 years ago
