docker支持gpu么

docker支持gpu，docker可以通过nvidia-docker2来使用GPU。在daemon.json文件中配置runtime使用nvidia，启动容器后运行nvidia-smi就能看到所有的GPU。

docker挂载 GPU的方法介绍：

使用 nvidia-docker2

简言之，使用 nvidia-docker2，可以不费吹灰之力就能使用到 GPU，仅仅需要配置 runtime 使用 nvidia

cat /etc/docker/daemon.json{    "default-runtime": "nvidia",    "runtimes": {        "nvidia": {"path": "/usr/bin/nvidia-container-runtime","runtimeArgs": []        }    },    "exec-opts": ["native.cgroupdriver=systemd"]}

启动容器之后，运行 nvidia-smi 能看到所有的 GPU 卡：

[root@localhost] docker run -it 98b41a1e975d bashroot@6db1dd28459d:/notebooks# nvidia-smi+-----------------------------------------------------------------------------+| NVIDIA-SMI 410.79       Driver Version: 410.79       CUDA Version: 10.0     ||-------------------------------+----------------------+----------------------+| GPU  Name        Persistence-M| Bus-Id        Disp.A | Volatile Uncorr.

通过 NVIDIA_DRIVER_CAPABILITIES 可以加入部分的 library。通过 NVIDIA_VISIBLE_DEVICES 可以只使用某些 GPU 卡

[root@localhost cuda-9.0]# docker run -it  --env NVIDIA_DRIVER_CAPABILITIES="compute,utility"  --env NVIDIA_VISIBLE_DEVICES=0,1 98b41a1e975d bashroot@97bf127ff83a:/notebooks# nvidia-smiTue Oct 15 09:29:45 2019+-----------------------------------------------------------------------------+| NVIDIA-SMI 410.79       Driver Version: 410.79       CUDA Version: 10.0     ||-------------------------------+----------------------+----------------------+| GPU  Name        Persistence-M| Bus-Id        Disp.A | Volatile Uncorr.
