问题：怎么不通过docker hub中转直接pull gcr(谷歌镜像仓库)的镜像呢？

1.shadowsocket开代理
本人使用的是deepin深度操作系统（感谢fenghan大神的指导），直接在商店下载Shadowsocket-QT5,配置代理信息：如下填写自己购买的代理服务

2.设置docker代理配置

sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="ALL_PROXY=socks5://127.0.0.1:1080"

root@:~#systemctl show --property=Environment docker
Environment=ALL_PROXY=socks5://127.0.0.1:1080

3.重启docker服务

root@:~# systemctl daemon-reload
root@:~# systemctl restart docker

4.docker pull 谷歌仓库镜像

root@:~# docker pull gcr.io/google_containers/pause-amd64:3.0
3.0: Pulling from google_containers/pause-amd64
