docker国内镜像地址

https://registry.docker-cn.com

http://hub-mirror.c.163.com

https://docker.mirrors.ustc.edu.cn

修改docker镜像地址为阿里云地址：

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'

{

  "registry-mirrors": ["https://aa25jngun.mirror.aliyuncs.com"]

}

EOF

sudo systemctl daemon-reload

sudo systemctl restart docker
