Troubleshooting
# Pod status
kubectl get pods -o wide
kubectl describe pod <name>
# Logs
kubectl logs <pod> -f
kubectl logs <pod> -c <container> --previous
# Shell access
kubectl exec -it <pod> -- /bin/sh
# Events
kubectl get events --sort-by='.lastTimestamp'
# Resource usage
kubectl top pods
kubectl top nodes
Common Issues
| Symptom | Check |
|---|---|
| ImagePullBackOff | Image name, registry auth |
| CrashLoopBackOff | Logs, resource limits |
| Pending | Resources, node selector |
| OOMKilled | Memory limits |
Helm
# Install
helm install myapp ./chart -f values.yaml
# Upgrade
helm upgrade myapp ./chart -f values.yaml
# Rollback
helm rollback myapp 1
