title: Kubernetes Ingress controllers for wildcard url mapping
body: <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>
