This is based on [Log in to Docker
Hub](https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/).
It is just a bit different to use podman

First we should take a look at podman-login man page:

``` bash
man podman login
```

It will give some valueable information like the location of auth.json
file. Now we can login using podman:

``` bash
podman login registry.gitlab.com
```

Then check the `auth.json` file located at
`${XDG_RUNTIME_DIR}/containers/auth.json` (as described by the manual).

``` bash
cat "${XDG_RUNTIME_DIR}/containers/auth.json"
```

It will print your auth config:

``` json
{
    "auths": {
        "registry.gitlab.com": {
            "auth": "..."
        }
    }
}
```

Now copy that file over to the server and register it in k8s with the
following command:

``` bash
kubectl create secret generic regcred \
    --from-file=.dockerconfigjson=auth.json \
    --type=kubernetes.io/dockerconfigjson
```

Once you have created you can list by `kubectl get secret`:

    NAME                                                    TYPE                                  DATA   AGE
    regcred                                                 kubernetes.io/dockerconfigjson        1      53s
