I have a kubernetes cluster which I am running tests on and I have setup an NGINX Ingress controller using this mage: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.11.0

As far as I so far understand Ingress Controllers, the setup seems to work as exepected except for that the ingress controller's default backend path is by default/. My current issue with this is that I have an ingress to a service (Harbor) whose default path is also /. Hence, I cannot get to the service and so I always get default backend 404 response. I have tried changing the Harbor service's ingress path to something other than / but upon calling the changed path, Harbor returns a 200 page but with just a Loading... string on it (I don't know if there is something hardcoded in Harbor that stops it liking any paths other than /?).

My question then is, is it possible to change the default backend's default path to something other than /? Or remove the default backend altogether? (I read online that it is not possible to remove the default backend). What options do I then have?
