Kubernetes Projects That Prove You Can Run Clusters

Most Kubernetes tutorials stop at kubectl apply. These are real cluster problems you diagnose and fix in a live workspace - a pod stuck in CrashLoopBackOff, a Service with no endpoints, an OOMKilled container, a broken readiness probe - and every one becomes a portfolio piece a hiring manager can open.

Why fixing a broken cluster beats another tutorial cluster

Standing up a cluster from a guide proves you can follow steps. Reading a pod's events, finding why it will not schedule, and getting it healthy proves you can operate one under pressure - which is the actual job. These drill that skill on real, broken state.

Pick by the skill to show

Debugging under pressure? The CrashLoopBackOff and failing-probe ones. Reliability and limits? The OOMKill and resource-quota ones. Networking? The Service and NetworkPolicy ones. Each finished fix is concrete evidence you can run Kubernetes, not just describe it.
