Architecture

Runbook library organized by failure domain: runtime crashes, image pull errors, CRI socket issues, OOMKill events, and node recovery procedures.

Operational Value

Problem Solved

Eliminates time spent rediscovering container runtime diagnostics during homelab incidents.

✓ Structured runbooks for 10+ common runtime failure scenarios
✓ Consistent diagnostic approach across containerd, CRI-O, and Docker
✓ CKA exam preparation through real operational documentation

Detailed case study documentation is in progress. See the GitHub repository for implementation details and README.
