I have .net Framework(4.6) based Web API service. i am hosting them in azure AKS.

I am using nignix and written Ingress Rule like this.

host: abc.com
    http:
     paths:
      - path: /EmailAPI
        backend:
          serviceName: esolvitemailapi-svc
          servicePort: 80

Now My web api is expecting URl

http://service/api/controller/action

But i think Ingres in sending the URI as

http://service/EmailAPI/api/controller/action

and i am getting 404 Error.

what is the best way to handle it. i don't want to do code change by doing [RoutePrefix("IdentityAPI/api")]

there are couple of apis and its big solution so it may break.

is there any think i can handle it at configuration level.

apiVersion: extensions/v1beta1
    kind: Ingress
    metadata:
      name: ingress-dev-backend
      annotations:
        kubernetes.io/ingress.class: nginx
        nginx.ingress.kubernetes.io/ssl-redirect: "false"
        nginx.ingress.kubernetes.io/rewrite-target: /$2
    spec:
     rules:
      - host: api.dev.arytic.com
        http:
         paths:       
         - backend:
            serviceName: esolvitidentityapi-svc
            servicePort: 80
           path: /IdentityAPI(/|$)(.*)
