<p>What is the correct way to expose a service <strong>behind</strong> an ingress.   Should I use nodePort? clusterIp? something else? because most tutorials just ignore this point. and some show the service using a nodePort and then add something like "would be enough for this demo" which isn't very reassuring.</p>

<p>Services behind an ingress may simply be ClusterIP. The only reason you'd need NodePort is if you had some external LoadBalancer or something where you needed a static port on which you can access the service inside the cluster. As ingresses route traffic within the cluster, you can just use ClusterIP.</p>
