Publishing the configurable app

Ingress objects reference Services in the local namespace, so you need to create your Ingress in the same namespace as the app:

• configurable-http.yaml

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 (or http://configurable.local:30000)

Using standard HTTP and HTTPS ports

For this all you need to do is change the public ports for the ingress controller LoadBalancer Service:

• controller/service-lb.yaml

kubectl apply -f labs/ingress/solution/controller

kubectl get svc -n ingress-nginx

Now you can use normal URLs:

• http://configurable.local
• http://pi.local
• http://localhost
• https://pi.local (you'll see an error about the TLS cert being untrusted)

Why can't you do this with a cluster that doesn't support LoadBalancer Services?

NodePorts are restricted to the unprivileged port range - 30000+. You can't have a NodePort listen on 80 or 443.
