更换docker的国内镜像源，可以加快镜像的下载。
1、在/etc/docker/下修改（如有）或创建daemon.json文件

nano /etc/docker/daemon.json

2、把以下内容复制进去：

{
    "registry-mirrors": [
        "https://registry.hub.docker.com",
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com"
    ]
}
