以下操作都是使用root用户

下载、上传、解压和移动到执行目录

1.到官方下载页面，找到对应硬件平台的docker-20.10.13.tgz 下载，并上传到debian系统上。我选择的是x86_64的。
2.解压并移动到执行目录上

tar xzvf docker-20.10.13.tgz
sudo cp docker/* /usr/bin/

3.创建deaemon.json配置文件
无法联网，需要docker连接内网镜像库
新建 /etc/docker文件夹
新建 /etc/docker/daemon.json 文件，并添加内容

{  
  "insecure-registries": [
    "192.168.1.230:8000"   
  ],
  "log-driver":"json-file",
  "log-opts": {"max-size":"2g", "max-file":"3"}
}

1.创建 /usr/lib/systemd/system/docker.service

nano /usr/lib/systemd/system/docker.service
