title: Can't access Service via Kubernetes Service with specified endpoints
body: <p>I've created a Kubernetes <strong>Service</strong> whose backend nodes aren't part of the Cluster but a fixed set of nodes (having fixed IPs), so I've also created an <strong>Endpoints</strong> resource with the same name:</p>
  
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: hive
  spec:
    type: ClusterIP
    ports:
      - name: http
        port: 80
        protocol: TCP
        targetPort: 10002
  ---
  apiVersion: v1
  kind: Endpoints
  metadata:
    name: hive
  subsets:
    - addresses:
        - ip: 10.52.7.28
        - ip: 10.52.7.29
      ports:
        - port: 10002
  </code></pre>
  
  <p>Description of Service and Endpoints:</p>
  
  <pre><code>$ kubectl describe svc/hive
  Name:              hive
  Namespace:         default
  Labels:            &lt;none&gt;
  Annotations:       &lt;none&gt;
  Selector:          &lt;none&gt;
  Type:              ClusterIP
  IP:                10.0.192.103
  Port:              http  80/TCP
  TargetPort:        10002/TCP
  Endpoints:
  Session Affinity:  None
  Events:            &lt;none&gt;
  $ 
  $ kubectl describe ep/hive
  Name:         hive
  Namespace:    default
  Labels:       &lt;none&gt;
  Annotations:  &lt;none&gt;
  Subsets:
    Addresses:          10.52.7.28,10.52.7.29
    NotReadyAddresses:  &lt;none&gt;
    Ports:
      Name     Port   Protocol
      ----     ----   --------
      &lt;unset&gt;  10002  TCP
  
  Events:  &lt;none&gt;
  </code></pre>
  
  <p>If I exec into one of the pods and telnet directly to Endpoint subset addresses, I am able to connect but If I access it via Service, I am getting connection refused. Just for completeness, Service and the pod are in same namespace:</p>
  
  <pre><code># telnet 10.52.7.28 10002
  Trying 10.52.7.28...
  Connected to 10.52.7.28.
  Escape character is '^]'.
  ^CConnection closed by foreign host.
  #
  # telnet 10.52.7.29 10002
  Trying 10.52.7.29...
  Connected to 10.52.7.29.
  Escape character is '^]'.
  ^CConnection closed by foreign host.
  #
  # telnet hive 80
  Trying 10.0.192.103...
  telnet: Unable to connect to remote host: Connection refused
  #
  </code></pre>
  
  <p>Any idea why I can directly connect to the IP but can't go via Kubernetes Service? I believe this isn't because of Firewall rules because then it should've blocked the direct requests as well.</p>
  
  <p><strong>Edit:</strong> I suspect its something to do with <code>Endpoints</code> being empty when I run <code>kubectl describe svc/hive</code> but I can see in the dashboard that Endpoints (under Service page) shows those Endpoints.</p>
