<p>I need for each of my users to access a service at a custom url eg. abccompany.mycloudapp.com , each service being a kubernetes service I'm looking at ingress controllers but I need a way to use a wildcard host field and somehow read the value into the path: and service: fields ; here's a sample ingress controller of what I have in mind:</p>

<pre><code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
 name: test
spec:
 rules:
 - host: *.bar.com
   http:
     paths:
     - path: /{{ value of * in * .bar.com }}
       backend:
         serviceName: {{value of * in *.bar.com }}Svc
         servicePort: 80
</code></pre>

<p>If you use the stock controllers you will be able to switch on hostname and go to different backends services. It sounds like you don't want to enumerate all the subdomains -> service mappings, in which case you probably need to write your own controller that writes out an nginx config that uses $http_host in the appropriate proxy_pass or redirect lines. Give it a shot (<a href="https://github.com/kubernetes/contrib/tree/master/ingress/controllers" rel="nofollow">https://github.com/kubernetes/contrib/tree/master/ingress/controllers</a>) and file bugs in that same repo if you need help. </p>
