我正试图让nvidia-docker在我的centos7系统上运行：

$ cat /etc/systemd/system/docker.service.d/override.conf
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd-current --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current --add-runtime=nvidia=/usr/bin/nvidia-container-runtime --default-runtime=docker-runc --exec-opt native.cgroupdriver=systemd --userland-proxy-path=/usr/libexec/docker/docker-proxy-current --seccomp-profile=/etc/docker/seccomp.json $OPTIONS $DOCKER_STORAGE_OPTIONS $DOCKER_NETWORK_OPTIONS $ADD_REGISTRY $BLOCK_REGISTRY $INSECURE_REGISTRY $REGISTRIES
$ cat /etc/docker/daemon.json
{
}
$ docker --version
Docker version 1.13.1, build 774336d/1.13.1
$ sudo systemctl daemon-reload
$ sudo systemctl restart docker

到目前为止，一切都很好：

    $ sudo docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

现在，让我们尝试使用nvidia运行时：

$ sudo docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi
standard_init_linux.go:178: exec user process caused "permission denied"

但是奇怪的是

$ sudo docker run --runtime=nvidia --rm nvidia/cuda sh -c nvidia-smi

回答：

所以…最后，我完全禁用了selinux并重新启动，并对其进行了修复。
