title: How to customize webhook port in openshift 4.5
body: <p>Creating a buildconfig and running <code>oc set triggers bc &lt;my_app&gt; --from-github</code> creates a webhook for me. However the port is on a non standard one. This causes issues for us since our internal github instance can only connect to e.g. 443 because of a company firewall.</p>
  <p>So this leads me to the question, where is this configured? How can I decide which port to use?</p>
