Phase 3 — Ingress Controller

Expose services running in the cluster to the local network.

Install NGINX Ingress Controller​

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/baremetal/deploy.yaml

Use the baremetal provider — this is for bare-metal nodes without a cloud load balancer.

Verify Installation​

kubectl get pods -n ingress-nginx

Wait until the ingress controller pod shows Running.

How It Works​

External request → NodePort (30000-32767)
                → Ingress Controller
                → Service
                → Pod

On bare-metal, you access apps via http://10.0.0.2:<nodeport> or with a local DNS entry pointing to a node IP.

Done When​

✔ ingress-nginx pod Running
✔ Can reach services via node IP
