或

sudo yum install -y yum-utils device-mapper-persistent-data lvm2  # CentOS/RHEL

3. 添加 Docker 官方 GPG 密钥

# Ubuntu/Debian
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

# CentOS/RHEL
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

4. 设置 Docker 软件源

# Ubuntu/Debian
echo "deb [arch=$(dpkg --print-architecture
