[Magnum] How to use docker CLI against a Magnum-managed Kubernetes cluster

Hello, I am trying to use docker CLI against a Magnum-managed Kubernetes cluster so as to interact with its Docker registry. I followed the steps as explained in https://docs.openstack.org/magnum/rocky/user/#interfacing-with-a-secure-clus... but magnum does not setup docker on tcp port so it cannot be accessed outside the minion node(where docker is running). I appreciate any help guiding how to use docker CLI. Thanks Namrata Sitlani
