✅ Pro Tips for Kubernetes Troubleshooting

Always check logs + kubectl describe pod pod_Name
Use resource requests / limits to avoid OOMKills
Use liveness / readiness probes to catch failure early
Make sure your image path, registry access, and credentials are correct
Watch scheduling constraints, taints, affinity, etc.
Test init containers independently (they often fail silently)
