These 15 resources will sharpen you for interviews and real production chaos

 
1. Explainshell – paste any bash command, and it breaks it down word by word. No more guessing awk or sed.


2. KubeSim – browser-based Kubernetes chaos drills. Crash etcd, break kube-proxy, see if you can recover.


3. AWS Fault Injection Simulator – inject failures in EC2, RDS, or EKS the way AWS does it.


4. etcd Playground – see how Kubernetes falls apart when its “memory” gets corrupted. Practice recovery.


5. Linux Strace Guide – the tool senior engineers use when logs are lying. Debug syscalls directly.


6. Azure Well-Architected Review – learn how Azure designs for availability, security, and cost trade-offs.


7. eBPF Academy – kernel-level observability. Trace sockets, latency, and network drops in real time.


8. Postmortem Templates (Google & Netflix) – write RCAs like FAANG engineers. Learn the structure that matters.


9. Container Security Playground (Katacoda) – hands-on labs to practice securing Docker/K8s workloads.


10. HAProxy Config Explorer – visualize advanced LB configs, spot bottlenecks before they break prod.


11. Helm Best Practices Repo – community-driven repo of anti-patterns and fixes. Learn beyond helm install.


12. Chaos Monkey (Netflix OSS) – the OG chaos tool. Still unmatched for teaching resilience culture.


13. Karpenter Workshop – master AWS-native autoscaling, and how it silently explodes costs if misused.


14. PromCat – curated, production-ready Prometheus dashboards built by Sysdig.


15. Incident.io Learning Hub – how modern teams structure incidents, on-call, and escalations.
