前言：基于Ubuntu Jammy 22.04 (LTS)版本安装和测试
1、Docker安装
1.1、离线安装
步骤一：官网下载 docker 安装包
wget https://download.docker.com/linux/static/stable/x86_64/docker-24.0.6.tgz
步骤二：解压安装包;
tar -zxvf docker-24.0.6.tgz
步骤三：将解压之后的docker文件移到 /usr/bin目录下;
sudo cp docker/* /usr/bin/
步骤四：将docker注册成系统服务;
vim /etc/systemd/system/docker.service
然后在文件中添加以下内容，退出并保存。
