K8S private gitlab registry using podman

This is based on Log in to Docker Hub. It is just a bit different to use podman.

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

        man podman login
    

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

        podman login registry.gitlab.com
    

Then check the auth.json file located at ${XDG_RUNTIME_DIR}/containers/auth.json (as described by the manual). It will contain your auth config:

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

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

        
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
