title: Kubernetes Externalname working with https
body: <p>We are trying to create an ExternalName service for Kubernetes to hide URL linking to our Firebase:</p>
  
  <pre><code>kind: Service
  apiVersion: v1
  metadata:
    name: firebase
    namespace: devel
  spec:
    type: ExternalName
    externalName: firebase-project-123456.firebaseio.com
  </code></pre>
  
  <p>The service is created correctly, and we can ping to <code>http://firebase</code>. However connecting to the firebase endpoint doesn't work:</p>
  
  <pre><code>curl -v http://firebase/activity.json
  &lt; HTTP/1.1 404 Not Found
  &lt; Content-Type: text/html; charset=UTF-8
  &lt; Referrer-Policy: no-referrer
  </code></pre>
  
  <p>One idea is that there is an issue with https (as the target service runs on https), however then we wouldn't probably get 404, but some other error. I have no idea what might be wrong on the way.</p>
