Hi, I've been struggling to set a rewrite rule for my ingress (GCP Kubernetes with a Deployment, Service NodePort and Ingress). What I'm trying to get is:

• api.example.com/ → backend/api/
• www.example.com/ → backend/www/

So that my server can server requests whether they start with /api/ or /www/, without a care about the subdomains.

I'm creating this issue because I have a question regarding your comment in https://github.com/kubernetes/ingress-gce#paths

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginxtest-ingress
spec:
  rules:
  - http:
      paths:
      - path: /hostname
        backend:
          serviceName: nginxtest
          servicePort: 80

Note what just happened, the endpoint exposes /hostname, and the loadbalancer forwarded the entire matching url to the endpoint. This means if you had '/foo' in the Ingress and tried accessing /hostname, your endpoint would've received /foo/hostname and not known how to route it.

I wish that was true... for me, loadbalancerip/foo would be the only queryable url, while everything else returns 404 Not Found errors. The Ingress only forward a request if it matches the path, that's it.

Anyways, if you have a suggestion regarding my problem, I'd really appreciate. Couldn't figure out how to get it working with annotations rewrite-url or app-root
