This self-hosted simulator provisions a full kubeadm cluster using Incus LXC containers as worker nodes. It supports three deployment modes: a disposable Lima VM on your laptop, a lightweight Docker kind setup, or a direct VPS install with 4 vCPUs and 8 GB RAM. Each mock exam question includes an automated setup script and a validator that grades your fixes against live cluster state.
It is worth trying if you are preparing for CKA or CKS and need practice with systemd and crictl on real nodes. The main catch is that AppArmor testing and specific worker node debugging are unavailable in the lightweight Docker mode, so you should use the VPS or laptop VM options for a complete experience.
