<h2>K8S private gitlab registry using podman</h2>
<p>
This is based on <a
href="https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/">Log in to
Docker Hub</a>. It is just a bit different to use podman.
</p>
<p>
First we should take a look at podman-login man page:
<pre>
<code>man podman login</code>
</pre>
</p>
<p>
It will give some valueable information like the location of auth.json file. Now we can login using podman:
<pre>
<code>podman login registry.gitlab.com</code>
</pre>
</p>
<p>Then check the <code>auth.json</code> file located at <code>${XDG_RUNTIME_DIR}/containers/auth.json</code> (as described
by the manual). It will contain your auth config:
<pre>
<code>
{
"auths": {
"registry.gitlab.com": {
"auth": "..."
}
}
}
</code>
</pre>
</p>
<p>
Now copy that file over to the server and register it in k8s with the following command:
<pre>
<code>
kubectl create secret generic regcred \
--from-file=.dockerconfigjson=auth.json \
--type=kubernetes.io/dockerconfigjson
</code>
</pre>
</p>
<p>
Once you have created you can list by kubectl get secret:
<pre>
<code>
NAME TYPE DATA AGE
regcred kubernetes.io/dockerconfigjson 1 53s
</code>
</pre>
</p>
