If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry ***.douins.com` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/***.douins.com/ca.crt
