Hands-On Labs

Lab 1: RBAC

kubectl create ns dev
kubectl create sa app -n dev
kubectl create role pod-reader --verb=get,list --resource=pods -n dev

Lab 2: Deployment Rollback

kubectl create deployment nginx --image=nginx:1.25
kubectl set image deployment/nginx nginx=nginx:broken
kubectl rollout undo deployment/nginx

Lab 3: PVC

Create PVC -> Mount Volume -> Write Data -> Restart Pod

Lab 4: Ingress

Create service -> Create ingress -> Test routing

YAML Library

apiVersion: apps/v1
kind: Deployment
spec:
  replicas: 3

apiVersion: v1
kind: PersistentVolumeClaim

apiVersion: networking.k8s.io/v1
kind: Ingress

Troubleshooting Decision Tree

Pod Fails ➜ kubectl describe ➜ Events ➜ Logs ➜ ImagePull? CrashLoop? Resource Limit?

Service Fails ➜ endpoints ➜ selector ➜ pod labels ➜ DNS

Storage Fails ➜ PVC Bound? ➜ PV Available? ➜ StorageClass?
