<p>I am new to Kubernetes.  Setting up nginx-ingress in a test cluster. One of our senior people rolled by and noticed the following.</p>
<pre><code># kubectl get services
...
ingress-ingress-nginx-controller-admission   ClusterIP      xx.xxx.xxx.xxx   &lt;none&gt;        443/TCP
...
</code></pre>
<p>What's that, he asked.  Get rid of it if you don't need it.</p>
<p>Before I rip it out and maybe get cripple my test cluster .. what <em>is</em> ingress-nginx-controller-admission and why do I need it?</p>

<p>It's the service for the validating webhook that ingress-nginx includes. If you remove it, you'll be unable to create or update Ingress objects unless you also remove the webhook configuration.</p>
<p>tl;dr it's important, no touchy</p>
