<p>I'm in china, so I access the gcr docker hub by a vpn.
I followed this link(<a href="https://docs.docker.com/config/daemon/systemd/#httphttps-proxy" rel="nofollow noreferrer">https://docs.docker.com/config/daemon/systemd/#httphttps-proxy</a>), so I can pull images(k8s.gcr) by docker. The infos are following:</p>
