一点星光，在心上就能反射出太阳

一、snap版docker

修改：

vim /var/snap/docker/current/config/daemon.json

二、apt版docker

vim /etc/docker/daemon.json

docker镜像：

阿里云

{
  "registry-mirrors": ["https://dg1w94af.mirror.aliyuncs.com"]
}

其他

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

重启docker以及daemon

systemctl daemon-reload
systemctl restart docker
