<p>When searching the image php:7.3.15-apache in openshift and we found it, but the same image is not found when searching using the docker search command. </p>

<p>Why it is like that ? Why docker pull can find the image but docker search can't find the image.</p>

<p>So you could either use 1 of that.</p>

<hr>

<p><strong>OR, if you want this specific version</strong></p>

<p>You can use <a href="https://docs.docker.com/engine/reference/commandline/pull/" rel="noreferrer">docker pull</a> </p>

<pre><code>docker pull php:7.3.15-apache

<p>And push it to your private registry with <a href="https://docs.docker.com/engine/reference/commandline/push/" rel="noreferrer">docker push</a> </p>

<pre><code>docker push

</ul>

<hr>

<p>And use your own registry instead of docker hub.</p>

<blockquote>
  <p>To deploy an image from a private repository, you must create an image pull secret with your image registry credentials. You have more informations under your Image Name.</p>
