# 1. 先安装基础依赖
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl gnupg

# 2. 创建目录
sudo mkdir -p /etc/apt/keyrings

# 3. 使用阿里云镜像下载GPG密钥（比官方源稳定）
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor --yes -o /etc/apt/keyrings/docker.gpg

# 4. 添加阿里云Docker源
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 5. 更新并安装
sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

#配置加载 
sudo systemctl daemon-reload  
#启动服务
