一、安装Docker
1.更新系统软件包
sudo apt update
sudo apt upgrade
2.安装所需的依赖库和工具：
sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release
3.添加Docker官方GPT秘钥：
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
4.设置Docker稳定版存储库
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
5.更新软件包索引：(这一步可要可不要，因为前面已经执行了)
sudo apt update
6.安装Docker引擎：
sudo apt install docker-ce docker-ce-cli containerd.io
7.添加当前用户到Docker组：
sudo usermod -aG docker $USER
安装成功以后提示：

二、安装Docker Compose
下载 Docker Compose 二进制文件：
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
添加执行权限：
sudo chmod +x /usr/local/bin/docker-compose
验证Docker Compose是否安装成功：
docker-compose version
