首先更新系统包并安装必要的依赖：
sudo apt update
sudo apt install ca-certificates curl gnupg lsb-release添加 Docker 的官方 GPG 密钥：
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
设置 Docker 稳定版仓库：
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null安装 Docker 引擎：
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin
查看docker版本
docker -v
查看docker是否运行
systemctl status docker.service
