5、配置docker镜像加速

#Docker 官方中国区
https://registry.docker-cn.com
#网易
http://hub-mirror.c.163.com
#ustc
https://docker.mirrors.ustc.edu.cn
#阿里
进入阿里云----搜索容器镜像服务----镜像加速

　　

修改 /etc/docker/daemon.json 文件并添加上 registry-mirrors 键值。

{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

 重启docker

systemctl daemon-reload
systemctl restart docker
