My ingress for azure application gateway, so that it will use istio gateway internally.
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: server-ingress
namespace: productnamespace
annotations:
kubernetes.io/ingress.class: azure/application-gateway
appgw.ingress.kubernetes.io/backend-protocol: "http"
appgw.ingress.kubernetes.io/cookie-based-affinity: "true"
cert-manager.io/cluster-issuer: letsencrypt-prod
appgw.ingress.kubernetes.io/health-probe-status-codes: "200-399, 401, 403"
spec:
tls:
- hosts:
- dev1.myproductnamespace.com
secretName: productnamespace-cert-secret
rules:
- host: dev1.myproductnamespace.com
http:
paths:
- path: /
pathType: Prefix
backend:
namespace: istio-system
service:
name: istio-gateway
port:
number: 80
istio-gateway is in istio-system namespace, And above ingress is in productnamespace. When I did port-forwarding for istio-gateway, it is able to access the product pages. So, istio gateway is good.
But route from azure app gateway ingress to istio-gateway ingress is failing.
In the events, it shows as below.
It is trying to search for istio-gateway in productnamespace instead of istio-system and failing.
