<p>i'm trying to pull an image from github packages in kubernetes but i keep getting the error &quot;no basic auth credentials&quot;</p>
<p>i created a secret with this command:</p>
<p>kubectl create secret docker-registry regcred --docker-server=docker.pkg.github.com         --docker-username=********* --docker-password=******* --docker-email=*****</p>
<p>and i added <strong>imagePullSecrets</strong> in the yaml file</p>
<p>i also have the config.json file with the credentials in $HOME/.docker/config.json in all the nodes of my cluster</p>
<p>Here is the content of the yaml file:</p>

<p>The secret have to be in the same namespace as the deployment to be able to use it to pull from the docker registry.<br />
So when you create the secret, you use:</p>
<pre><code>kubectl create secret docker-registry regcred \
  --namespace=jhipster \ # &lt;--
  --docker-server=docker.pkg.github.com \
  --docker-username=********* \
  --docker-password=******* \
  --docker-email=*****
</code></pre>
<p>It might also be an issue if you use 2fa and password (in the regcred), in which case you aught to create an access token to use as password instead.</p>
