1. 更新你的包管理器和安装必要的包
sudo apt-get update
sudo apt-get install -y \
ca-certificates \
curl \
gnupg \
lsb-release
2. 添加Docker的官方GPG密钥
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
4. 安装Docker Engine
现在，你可以安装Docker Engine了：
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
\>
百度云服务器：
apt install docker.io
5\ 设置Docker 启动
sudo systemctl start docker
sudo systemctl enable docker
