HTTP presentations don't work due to nonstandard ports

[Mierdin]

I was going to work on this a while back but decided to do something else. In the meantime, I'll open an issue describing the problem.

In short, the Kubernetes Ingress API really seems to be incompatible with nonstandard ports. Having ports in the route for an ingress is explicitly not allowed, yet as a result, routing decisions to endpoints with nonstandard ports doesn't work. This issue is described well in kubernetes/kubernetes#41881

So while the whole stack works, HTTP presentations don't work in selfmedicate. The solution may be to use host networking for the nginx pods
