Infra Debug

Infrastructure Debugging

Debug the deployment for $ARGUMENTS.

Parse arguments:

• First argument: environment (staging or production). Default to staging.
• Second argument: what to inspect (pods, logs, events, ingress, describe, all). Default to all.

Namespace mapping:

• staging → books-staging
• production → books-production

Debug Commands

pods - Pod Status

kubectl get pods -n <namespace> -l app.kubernetes.io/name=goravel-blog -o wide
kubectl top pods -n <namespace> -l app.kubernetes.io/name=goravel-blog 2>/dev/null

Flag any pod that is NOT Running or has restarts > 0.

logs - Application Logs

For each pod:

kubectl logs -n <namespace> <pod-name> --tail=100

If a pod has restarted, also get previous logs:

kubectl logs -n <namespace> <pod-name> --previous --tail=50

Look for error patterns: panic, fatal, error, failed to connect, timeout.

events - Cluster Events

kubectl get events -n <namespace> --sort-by='.lastTimestamp' | tail -30

Flag any Warning events and explain likely causes.

ingress - Ingress & Networking

kubectl get ingress -n <namespace>
kubectl describe ingress -n <namespace> goravel-blog
kubectl get svc -n <namespace>
kubectl get endpoints -n <namespace>

Check:

• Ingress has an address assigned
• Backend endpoints exist and are healthy
• TLS certificate is valid (if applicable)

describe - Full Resource Description

kubectl describe deployment goravel-blog -n <namespace>
kubectl describe pod -n <namespace> -l app.kubernetes.io/name=goravel-blog

Look for:

• Image pull errors
• Resource limit issues (OOMKilled)
• Scheduling failures (insufficient resources, node selectors)
• Init container failures (migration errors)

all - Full Diagnostic

Run all of the above in sequence, then provide a summary:

Common Issues & Fixes

Based on findings, suggest specific fixes:

• CrashLoopBackOff: Check logs for panic/connection errors. Likely DB or Redis unreachable.
• ImagePullBackOff: Image tag doesn't exist. Check if CI built it.
• OOMKilled: Increase memory limits in values file.
• Init container failed: Migration error. Check init container logs.
• No endpoints: Service selector doesn't match pod labels.
• 503 errors: No healthy pods behind the ingress.

Helm Status

Also show:

helm status goravel-blog -n <namespace>
helm history goravel-blog -n <namespace> --max 5
