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
