sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
添加Docker官方GPG密钥
在终端中执行以下命令，添加Docker官方GPG密钥：
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
添加Docker源
在终端中执行以下命令，添加Docker源：
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
更新软件包缓存
在终端中执行以下命令，更新软件包缓存：
sudo apt-get update
安装Docker
在终端中执行以下命令，安装Docker：
sudo apt-get install docker-ce docker-ce-cli containerd.io
