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.

For those actively teachingยน, consider Snap! (https://snap.berkeley.edu/) over/after Scratch. It's nearly a superset, similarly "low-floor" but much "higher ceiling" powerful language. Data structures, control structures/message passing, functional programming... It's really "Scheme in Scratch clothing" under the hood. In particular, its "build your own blocks" facilities are powerful enough (including macros... - Source: Hacker News / 9 months ago
Snap! https://snap.berkeley.edu/ Also, I heartily recommend the demoes that the author is giving regularly at FOSDEM. They're really fun to watch :). - Source: Hacker News / about 1 year ago
Kids would probably have a better experience with Hedy https://hedy.org if they are young, and Pyret https://dcic-world.org if they are a little older. Once they know how to program python is obviously a fine choice, but starting beginners with Python is insane. Too many gotchas, incomprehensible error messages etc. Also why logo? Its not 1967 anymore. A far better choice is Snap! https://snap.berkeley.edu. - Source: Hacker News / over 1 year ago
I upgraded my son from Scratch to Snap! (https://snap.berkeley.edu/). Snap has a much higher ceiling, including collections, first-class code pieces, higher-order functions etc. It pretty openly describes itself as a "Scheme disguised as Scratch" :-) A pragmatic pedagogical thing I love with Snap! Is the ease of creating custom blocks, including macros / custom "C-shaped" control structures. If you have some... - Source: Hacker News / almost 2 years ago
Take a look at Snap. It was originally a scratch mod, but does allows for all sorts of advanced things. https://snap.berkeley.edu. - Source: Hacker News / over 2 years ago
