A Kubernetes exam lab that can actually break kubelet, systemd, and etcd for real practice.

Webfree

K16S is a CKA/CKS Kubernetes certification exam lab that lets learners practice on a real, breakable environment covering kubelet, systemd, etcd, and certificates, rather than a sandboxed simulator. It's aimed at people studying for Kubernetes certification exams who want realistic troubleshooting practice instead of a simplified simulator.
