docker19.03使用NVIDIA显卡
前言
2019年7月的docker 19.03已经正式发布了，这次发布对我来说有两大亮点。
1，就是docker不需要root权限来启动喝运行了
2，就是支持GPU的增强功能，我们在docker里面想读取nvidia显卡再也不需要额外的安装nvidia-docker了
安装nvidia驱动
确认已检测到NVIDIA卡:
$ lspci -vv | grep -i nvidia 00:04.0 3D controller: NVIDIA Corporation GP100GL [Tesla P100 PCIe 16GB] (rev a1) Subsystem: NVIDIA Corporation GP100GL [Tesla P100 PCIe 16GB] Kernel modules: nvidiafb
这里不再详细介绍：如果不知道请移步ubuntu离线安装TTS服务
安装NVIDIA Container Runtime
$ cat nvidia-container-runtime-script.sh curl -s -L https://nvidia.github.io/nvidia-container-runtime/gpgkey | \ sudo apt-key add - distribution=$(. /etc/os-release;echo $ID$VERSION_ID) curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.list | \ sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list sudo apt-get update
执行脚本
sh nvidia-container-runtime-script.sh

安装docker-19.03
# step 1: 安装必要的一些系统工具 yum install -y yum-utils device-mapper-persistent-data lvm2 # Step 2: 添加软件源信息 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # Step 3: 更新并安装 Docker-CE yum makecache fast yum -y install docker-ce-19.03.2 # Step 4: 开启Docker服务 systemctl start docker && systemctl enable docker
验证docker版本是否安装正常
$ docker version Client: Docker Engine - Community Version: 19.03.2 API version: 1.40 Go version: go1.12.8 Git commit: 6a30dfc Built: Thu Aug 29 05:28:55 2019 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community Engine: Version: 19.03.2 API version: 1.40 (minimum version 1.12) Go version: go1.12.8 Git commit: 6a30dfc Built: Thu Aug 29 05:27:34 2019 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.2.6 GitCommit: 894b81a4b802e4eb2a91d1ce216b8817763c29fb runc: Version: 1.0.0-rc8 GitCommit: 425e105d5a03fabd737a126ad93d62a9eeede87f docker-init: Version: 0.18.0 GitCommit: fec3683
验证下-gpus选项
$ docker run --help | grep -i gpus
--gpus gpu-request GPU devices to add to the container ('all' to pass all GPUs)运行利用GPU的Ubuntu容器
$ docker run -it --rm --gpus all ubuntu nvidia-smi Unable to find image 'ubuntu:latest' locally latest: Pulling from library/ubuntu f476d66f5408: Pull complete 8882c27f669e: Pull complete d9af21273955: Pull complete f5029279ec12: Pull complete Digest: sha256:d26d529daa4d8567167181d9d569f2a85da3c5ecaf539cace2c6223355d69981 Status: Downloaded newer image for ubuntu:latest Tue May 7 15:52:15 2019 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 390.116 Driver Version: 390.116 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

故障排除
您是否遇到以下错误消息：
$ docker run -it --rm --gpus all debian docker: Error response from daemon: linux runtime spec devices: could not select device driver "" with capabilities: [[gpu]].
上述错误意味着Nvidia无法正确注册Docker。它实际上意味着驱动程序未正确安装在主机上。这也可能意味着安装了nvidia容器工具而无需重新启动docker守护程序：您需要重新启动docker守护程序。
我建议你回去验证是否安装了nvidia-container-runtime或者重新启动Docker守护进程。
列出GPU设备
$ docker run -it --rm --gpus all ubuntu nvidia-smi -L GPU 0: Tesla P4 (UUID: GPU-fa974b1d-3c17-ed92-28d0-805c6d089601)
$ docker run -it --rm --gpus all ubuntu nvidia-smi --query-gpu=index,name,uui d,serial --format=csv index, name, uuid, serial 0, Tesla P4, GPU-fa974b1d-3c17-ed92-28d0-805c6d089601, 0325017070224
待验证，因为我现在没有GPU机器---已经验证完成，按照上述操作可以在docker里面成功的驱动nvidia显卡
