Real-Life Example: Helm on Azure AKS

# Add Bitnami repo and install Prometheus on AKS
helm repo add bitnami https://charts.bitnami.com/bitnami
helm install prometheus bitnami/kube-prometheus --namespace monitoring --create-namespace

Real-Life Example: Velero Backup to AWS S3

velero install \
  --provider aws \
  --bucket my-k8s-backups \
  --secret-file ./aws-credentials \
  --backup-location-config region=us-west-2

Real-Life Example: ArgoCD GitOps on GKE

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
# Connect ArgoCD to a Git repo for automated app deployment
