1.找到阿里云镜像加速地址(https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors)
https://XXX.mirror.aliyuncs.com
2. docker文件
other_args="--registry-mirror=https://XXX.mirror.aliyuncs.com"
3.servier docker restart  

4.ps -ef|grep docker 
如果 docker进程格式为/user/bin/docker --registry-mirror=https://XXX.mirror.aliyuncs.com
则 配置镜像加速成功

如果是centos7或以上，则编写 /etc/docker/daemon.json 文件,文件内容为:
{
  "registry-mirrors": ["https://XXX.mirror.aliyuncs.com"]
}

直接执行代码为:
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://XXX.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
