<p>I am sure I am missing something clear as day, but here goes. I have a frontend and backend being deployed behind an Nginx ingress. The requests to the backend were timing out, so I tested with a <code>curl</code> pod. I found that I was able to hit the pods directly, but not the service. This led me to run:</p>
<pre class="lang-sh prettyprint-override"><code>&gt; kubectl get endpoints

<p>No endpoints... I recall (from when I initially set this deployment up) that this usually has to do with selectors. I have checked and checked and checked, but I swear I have it set up correctly. Clearly not though.</p>

<p>Help is, of course, appreciated :) I normally beat my head against the wall for hours, but I'm learning to work smarter, not harder!</p>
<p>Happy to answer any questions - thanks in advance!</p>

<p>It looks like you got the service ports mixed up. <code>targetPort</code> is set to <code>http</code>, which is port 80. This is the port that the service forwards to on the pod. The <code>port</code> value of the service is the port service exposes. So if you want your service to forward traffic to port 8080 of your pod, set <code>targetPort</code> to 8080.</p>
