1. 配置国内镜像加速
cat > /etc/containers/registries.conf <<EOF
unqualified-search-registries = ["docker.io"]
[[registry]]
prefix = "docker.io"
location = "docker.io"
[[registry.mirror]]
location = "hub-mirror.c.163.com"
[[registry.mirror]]
location = "mirror.baidubce.com"
[[registry.mirror]]
location = "docker.mirrors.ustc.edu.cn"
EOF
2. 配置 GPU 支持（官方正确方法）
nvidia-ctk runtime configure --runtime=podman
systemctl restart podman
3. 验证 Podman GPU
podman run --gpus all --rm nvidia/cuda:12.6-base-ubuntu22.04 nvidia-smi
