阿里云docker 镜像加速器

https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

每个阿里云的账号实际的对应地址是不一样的，自己登录账号检查：

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://xho6846t.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
