<p>Im trying to run a cron job in a digital ocean kubernetes cluster. The image is hosted as a github package. I am getting an authenticatin error when the image is being pulled. I also get the same error when trying to pull directly from docker in the command line. Is that the same problem? Or do I need to auth in 2 differnet places?</p>

<p>You can't pull anonymously from <code>docker.pkg.github.com</code>, you'll have to create a dockercfg with some GitHub access token and use it as <code>imagePullSecret</code>.</p>
<p>If you want to publicly host your image on GitHub you can use the newer <code>ghcr.io</code> container registry, which provides anonymous pulling capabilities for public images.</p>
