Docker 加载内核模块
================================================================================

1. Add `--cap-add SYS_MODULE` to your Docker run command to allow the container to load/unload kernel modules.
2. Bind-mount the Docker host's `/lib/modules` directory into the container. e.g. `-v /lib/modules:/lib/modules:ro`
