Guides
In-depth, evidence-driven guides to debugging and operating Kubernetes, ArgoCD and CI/CD — the kind you keep open during an incident.
Debugging GitHub PR & merge failures: a field guide
GitHub
A systematic way to debug a GitHub pull request that will not merge — read the mergeable state first, then route to the right cause: conflict, behind, blocked check, review, or webhook gap.
Diagnosing Bitbucket pipeline & merge failures: a field guide
Bitbucket
A systematic way to debug Bitbucket Cloud — split a pipeline that never ran from one that failed, see why merge checks warn instead of block, and migrate off app passwords.
Kubernetes OOMKilled: a complete debugging guide
Kubernetes
Diagnose and fix OOMKilled pods in Kubernetes — confirm the kill, understand reactive kernel enforcement, find the real cause, and stop it recurring. Cited to the official docs.
Jenkins CI failures: a debugging field guide
Jenkins
Debug Jenkins pipeline and build failures systematically — read the end state first, isolate the failing stage and its log, tell queued from failing, then triage to the right fix.
Diagnosing ArgoCD: sync and health failures
ArgoCD
A triage framework for troubleshooting ArgoCD applications: read sync status and health status as two independent axes, classify the failure, then jump to the fix.
Debugging Kubernetes pod failures: a field guide
Kubernetes
A triage-first field guide to debugging Kubernetes pods. Read STATUS, describe Events and Last State, and route each failure to its fix instead of guessing.
