<p>I have a kinda weird set up where I have a general url(<a href="http://www.example.com" rel="nofollow noreferrer">www.example.com</a>) that terminates on an F5 that points to a nginx VS on an EKS cluster that has a localized domain(<a href="http://www.ue1.example.com" rel="nofollow noreferrer">www.ue1.example.com</a>).</p>
<p>So the flow is user --&gt;&gt; <a href="http://www.example.com" rel="nofollow noreferrer">www.example.com</a> --&gt; F5 --&gt; F5 xforwards host header of <a href="http://www.ue1.example.com" rel="nofollow noreferrer">www.ue1.example.com</a> --&gt; nginx vs --&gt; web service that is licenses for <a href="http://www.example.com" rel="nofollow noreferrer">www.example.com</a>.</p>
<p>nginx needs a host of <a href="http://www.ue1.example.com" rel="nofollow noreferrer">www.ue1.example.com</a> but then convert it to <a href="http://www.example.com" rel="nofollow noreferrer">www.example.com</a> before sending it to the web service.</p>

# Using route and proxy with a NGINX virtualserver K8s config

(Asked by: username_0 on 2024-01-14)

I have a kinda weird set up where I have a general url(www.example.com) that terminates on an F5 that points to a nginx VS on an EKS cluster that has a localized domain(www.ue1.example.com).
So the flow is user -->> www.example.com --> F5 --> F5 xforwards host header of www.ue1.example.com --> nginx vs --> web service that is licenses for www.example.com.
nginx needs a host of www.ue1.example.com but then convert it to www.example.com before sending it to the web service.
So is there a way to route to a virtulserverroute AND proxy the host header as well. Here are the relevant configs. Not sure where to put the proxy information.
apiVersion: k8s.nginx.org/v1
kind: VirtualServer
metadata:
  name: example
spec:
  host: example.ue1.eexchange.com
  routes:
    - path: /
      route: example/example

apiVersion: k8s.nginx.org/v1
kind: VirtualServerRoute
metadata:
  name: example
spec:
  upstreams:
    - name: example-service
      service: example
      port: 80
  subroutes:
