Problem Description

I want to expose the portaner interface (port 9000) behind an Istio proxy. Here the yaml that I used:
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: bookinfo-gateway-external
spec:
selector:
istio: aks-istio-ingressgateway-external
servers:

• port:
  number: 80
  name: http
  protocol: HTTP
  hosts:
  • "*"

---

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: bookinfo-vs-external
spec:
hosts:

• "*"
  gateways:
• bookinfo-gateway-external
  http:
• match:
  • uri:
    prefix: "/portainer"
    rewrite:
    uri: "/"
    route:
  • destination:
    host: portainer.portainer.svc.cluster.local
    port:
    number: 9000

When I open the path, the portainer is found but say: Failure
Unable to retrieve server settings and status and the insterface is stopped. If I sue standard node port, it works correctly

Expected Behavior

Same behavious when opened by node port

Actual Behavior

Doesn't work behind Istio proxy

Steps to Reproduce

• install portainer in AKS with Istio enabled
• install Istio configuraion file:
  apiVersion: networking.istio.io/v1alpha3
  kind: Gateway

  servers:
  • port:
    number: 80
    name: http
    protocol: HTTP
    hosts:
    • "*"
