docker和GPU

架构图

 

 

安装gpu runtime

https://nvidia.github.io/nvidia-container-runtime/

-----

cat /etc/redhat-release 

CentOS Linux release 7.6.1810 (Core) 

------

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)

curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.repo |   sudo tee /etc/yum.repos.d/nvidia-container-runtime.repo

sudo yum install nvidia-container-runtime

-----

cat /etc/docker/daemon.json

{

    "default-runtime": "nvidia",

    "runtimes": {

        "nvidia": {

            "path": "/usr/bin/nvidia-container-runtime",

            "runtimeArgs": []

        }

    },

    "registry-mirrors": ["http://28cf50e2.m.daocloud.io"],

    "storage-driver": "overlay2",

    "storage-opts": [

        "overlay2.override_kernel_check=true"

    ],

    "graph": "/data/data/docker",

    "log-driver": "json-file",

    "log-opts": {

      "max-size": "300m",

      "max-file": "3"

    }

}

---

systemctl daemon-reload

 

宿主机安装显卡驱动

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=CentOS&target_version=7&target_type=rpm_network

sudo yum-config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-rhel7.repo
sudo yum clean all
sudo yum -y install nvidia-driver-latest-dkms cuda
sudo yum -y install cuda-drivers

 

下载官方镜像 我司使用基于centos 的gpu 版本

 

https://hub.docker.com/r/nvidia/cuda/tags?page=1&ordering=last_updated

docker pull nvidia/cuda:11.4.1-devel-centos8

docker run -d  --gpus '"device=1,2"'  nvidia/cuda:11.4.1-devel-centos8  sleep 30000000000
