Hello, im testing out Istio, but i'm having issues with rewriting requests from ingress.

e.g.

I have Istio running from the Helm chart, all default configuration.

I have a demo application, which accepts requests from root.. so locally i can

docker run -p 80:80 my.registry.com/one-demo

Request: curl localhost/
Response: 200

I have this application running on my k8s, with an ingress record using the rewrite-target to /

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: one-demo
  namespace: "{{.Values.namespace}}"
  annotations:
    kubernetes.io/ingress.class: istio
    ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /demo
        backend:
          serviceName: one-demo
          servicePort: 8080

Request: curl istiolb.mydomain.com/demo
Response: 404

Looking at the access log for my demo app, i see

request: "GET /demo HTTP/1.1"
Is there a way i can ensure that the request is re-written to the root path?

Cheers
