Ingress objects reference Services in the local namespace, so you need to create your Ingress in the same namespace as the app:
kubectl apply -f labs/ingress/solution/ingress
It's a new domain so you need to add it to your hosts file:
# on Windows: ./scripts/add-to-hosts.ps1 configurable.local 127.0.0.1 # on *nix: ./scripts/add-to-hosts.sh configurable.local 127.0.0.1
Now you can browse to http://configurable.local:8000
For this all you need to do is change the public ports for the ingress controller LoadBalancer Service:
kubectl apply -f labs/ingress/solution/controller kubectl get svc -n ingress-nginx
Now you can use normal URLs:
NodePorts are restricted to the unprivileged port range - 30000+. You can't have a NodePort listen on 80 or 443.
Back to the exercises.
