1，使用以下命令直接从该镜像加速地址进行拉取。
命令：docker pull registry.docker-cn.com/myname/myrepo:mytag
例：docker pull registry.docker-cn.com/library/ubuntu:16.10
注:除非修改了Docker守护进程的–registry-mirror参数,
否则需要完整地指定镜像的名称。例，library/ubuntu、library/redis、library/nginx。
2，使用 --registry-mirror配置Docker守护进程加速。
★临时生效：
Docker守护进程启动时传入 --registry-mirror 参数：
\# docker --registry-mirror=https://xxxxxxxx.mirror.aliyuncs.com daemon
★永久生效：
通过配置文件启动Docker,修改/etc/docker/daemon.json 文件并添加上 registry-mirrors 键值。
vim /etc/docker/daemon.json
或者
◆ 配置镜像加速1：
阿里的镜像地址：https://xxxxxxxx.mirror.aliyuncs.com(私人账号地址)
{
"registry-mirrors": ["https://xxxxxxxx.mirror.aliyuncs.com"]
}
- 可以配置多个镜像加速地址，用逗号分隔。
"registry-mirrors":["https://registry.docker.cn.com","https://docker.mirrors.ustc.edu.cn/"]
◆ 配置镜像加速2：
文档参考：https://www.daocloud.io/mirror
Linux下命令：
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
{
"registry-mirrors": ["https://xxxxxxxx.m.daocloud.io"]
}
◆ 临时使用：
- 使用163的docker仓库，拉取镜像
网易的镜像地址：https://hub-mirror.c.163.com/
docker pull hub.c.163.com/public/centos:7.2
3，修改保存后，重启Docker以使配置生效。
sudo systemctl daemon-reload
sudo systemctl restart docker
4，查看配置是否生效。
执行docker info，查看是否含有如下信息：
Registry Mirrors:
https://xxxxxxxx.mirror.aliyuncs.com/
5,补充
docker daemon.json的完整配置示例及说明参照：https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file
