Why DNS failures, expired certificates, label selector mismatches, and network policy blocks cause more outages than packet loss — and how to debug them.
How to debug CrashLoopBackOff in Kubernetes: the six real causes — startup failures, OOMKills, bad probes, image pulls, volumes, and rollouts.
Pods stuck Pending in Kubernetes? Learn the 7 scheduler failures — from insufficient CPU to affinity deadlocks — and how to diagnose them fast.
Test API throttling, RBAC denials, and admission webhook failures locally — without a real cluster. Faster, cheaper, and more targeted than chaos engineering.
A practical taxonomy of Kubernetes failure modes — control plane, workload, config, networking, storage — from real production incidents and benchmark data.
64% of outages come from config and change errors, not dead disks. Learn the semantic/physical failure split and why you can simulate most of them locally.
Chaos experiments test the dramatic failures that rarely happen. A failure catalog targets the config, dependency, and control-plane bugs that actually take you down.
