title: ingress configuration for dashboard
body: <p>I did nginx ingress controller tutorial from <a href="https://github.com/kubernetes/ingress-nginx/blob/master/deploy/README.md" rel="noreferrer">github</a> and
  exposed kubernetes dashboard</p>
  
  <pre><code>kubernetes-dashboard   NodePort    10.233.53.77    &lt;none&gt;        443:31925/TCP   20d
  </code></pre>
  
  <p>created ingress </p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    annotations:
      ingress.kubernetes.io/ssl-passthrough: "true"
      nginx.org/ssl-backends: "kubernetes-dashboard"
      kubernetes.io/ingress.allow-http: "false"
    name: dashboard-ingress
    namespace: kube-system
  spec:
    tls:
    - hosts:
      - serverdnsname
      secretName: kubernetes-dashboard-certs
    rules:
    - host: serverdnsname
      http:
        paths:
        - path: /dashboard
          backend:
            serviceName: kubernetes-dashboard
            servicePort: 443
  </code></pre>
  
  <hr>
  
  <pre><code>ingress-nginx   ingress-nginx          NodePort    10.233.21.200   &lt;none&gt;        80:30827/TCP,443:32536/TCP   5h
  </code></pre>
  
  <p><a href="https://serverdnsname:32536/dashboard" rel="noreferrer">https://serverdnsname:32536/dashboard</a>
  but dashboard throws error </p>
  
  <pre><code>2018/01/18 14:42:51 http: TLS handshake error from ipWhichEndsWith.77:52686: tls: first record does not look like a TLS handshake
  </code></pre>
  
  <p>and ingress controller logs</p>
  
  <pre><code>2018/01/18 14:42:51 [error] 864#864: *37 upstream sent no valid HTTP/1.0 header while reading response header from upstream, client: 10.233.82.1, server: serverdnsname, request: "GET /dashboard HTTP/2.0", upstream: "http://ipWhichEndsWith.249:8443/dashboard", host: "serverdnsname:32536"

  </code></pre>
  
  <p>On my mind it is related with nginx redirection to upstream: "<a href="http://ipWhichEndsWith.249:8443/dashboard" rel="noreferrer">http://ipWhichEndsWith.249:8443/dashboard</a>" .
  tried to update controller image version to 0.9.0-beta.19 - didnt help</p>
  
  <p>Thank you for any help.</p>
