A. Quick Clarity (2-3 min read)
What is this topic? Kubernetes Production Guide
Why important? Production-focused Kubernetes: control plane, workloads, policies, Helm, and GitOps.
Where used? Production systems on cloud platforms like Amazon Web Services, with containers and orchestration.
What you will learn? Core concept, practical flow, troubleshooting, and interview-ready understanding.
Cloud example: Amazon Web Services (AWS)
B. Concept Explanation
Core idea: Production Patterns.
Analogy: Think of DevOps as a delivery highway where code moves from idea to production with checkpoints.
Architecture flow: User -> Application -> Container -> Kubernetes -> Cloud -> Monitoring
- RBAC
- Network policies
- Ingress and autoscaling
C. Practical Section
Hands-on commands and examples for real usage.
Command Table
kubectl get pods -A
kubectl describe pod <pod>
kubectl rollout status deployment/api
D. Real DevOps Context
- Used in production delivery pipelines and cloud operations.
- Common platforms: Amazon Web Services, Docker, Kubernetes.
- Common mistake: jumping to advanced tools before concept clarity.
- Industry use: teams use this to improve release speed and reliability.
E. Troubleshooting
CrashLoopBackOff
Why it happens: Container startup failed due to missing env/config dependency.
How to fix: kubectl get pods | kubectl describe pod <pod> | kubectl logs <pod> --previous
502 Bad Gateway
Why it happens: Upstream app process not listening on expected port.
How to fix: sudo nginx -t | ss -lntp | curl -I http://localhost:<port>
High CPU
Why it happens: Hot endpoint and insufficient resource limits.
How to fix: top | ps aux --sort=-%cpu | head | kubectl top pod
F. Mini Practice Task
Try this now: Deploy one sample app on Kubernetes and check rollout status.
