Using GPU from a docker container

Question

I m searching for a way to use the GPU from inside a docker container   The container will execute arbitrary code so i don t want to use the privileged mode   Any tips    From previous research i understood that run -v and or LXC cgroup was the way to go but i m not sure how to pull that off exactly

I would not recommend installing CUDA cuDNN on the host if you can use docker  Since at least CUDA 8 it has been possible to  quot stand on the shoulders of giants quot  and use nvidia cuda base images maintained by NVIDIA in their Docker Hub repo  Go for the newest and biggest one  with cuDNN if doing deep learning  if unsure which version to choose  A starter CUDA container  mkdir   cuda11 cd   cuda11  echo  quot FROM nvidia cuda 11 0-cudnn8-devel-ubuntu18 04 quot   gt  Dockerfile echo  quot CMD    quot  bin bash  quot   quot   gt  gt  Dockerfile  docker build --tag mirekphd cuda11    docker run --rm -it --gpus 1 mirekphd cuda11 nvidia-smi   Sample output   if nvidia-smi is not found in the container  do not try install it there - it was already installed on thehost with NVIDIA GPU driver and should be made available from the host to the container system if docker has access to the GPU s     -----------------------------------------------------------------------------    NVIDIA-SMI 450 57       Driver Version  450 57       CUDA Version  11 0        ------------------------------- ---------------------- ----------------------    GPU  Name        Persistence-M  Bus-Id        Disp A   Volatile Uncorr  ECC     Fan  Temp  Perf  Pwr Usage Cap          Memory-Usage   GPU-Util  Compute M                                                                           MIG M                                                                                        0  GeForce GTX 108     Off    00000000 01 00 0  On                    N A      0    50C    P8    17W   280W      409MiB   11177MiB        7       Default                                                                             N A    ------------------------------- ---------------------- ----------------------   Prerequisites  Appropriate NVIDIA driver with the latest CUDA version support to be installed first on the host  download it from NVIDIA Driver Downloads and then mv driver-file run driver-file sh  amp  amp  chmod  x driver-file sh  amp  amp    driver-file sh   These are have been forward-compatible since CUDA 10 1   GPU access enabled in docker by installing sudo apt get update  amp  amp  sudo apt get install nvidia-container-toolkit   and then restarting docker daemon using sudo systemctl restart docker

To use GPU from docker container  instead of using native Docker  use Nvidia-docker  To install Nvidia docker use following commands  curl -s -L https   nvidia github io nvidia-docker gpgkey    sudo apt-key add - curl -s -L https   nvidia github io nvidia-docker ubuntu16 04 amd64 nvidia- docker list   sudo tee  etc apt sources list d nvidia-docker list sudo apt-get update sudo apt-get install -y nvidia-docker sudo pkill -SIGHUP dockerd   Restart Docker Engine sudo nvidia-docker run --rm nvidia cuda nvidia-smi   finally run nvidia-smi in the same container

Use x11docker by mviereck   https   github com mviereck x11docker hardware-acceleration says     Hardware acceleration      Hardware acceleration for OpenGL is possible with option -g  --gpu       This will work out of the box in most cases with open source drivers on host  Otherwise have a look at wiki  feature dependencies        Closed source NVIDIA drivers need some setup and support less x11docker X server options    This script is really convenient as it handles all the configuration and setup  Running a docker image on X with gpu is as simple as  x11docker --gpu imagename

Writing an updated answer since most of the already present answers are obsolete as of now   Versions earlier than Docker 19 03 used to require nvidia-docker2 and the --runtime nvidia flag    Since Docker 19 03  you need to install nvidia-container-toolkit package and then use the --gpus all flag   So  here are the basics   Package Installation  Install the nvidia-container-toolkit package as per official documentation at Github   For Redhat based OSes  execute the following set of commands     distribution      etc os-release echo  ID VERSION ID    curl -s -L https   nvidia github io nvidia-docker  distribution nvidia-docker repo   sudo tee  etc yum repos d nvidia-docker repo    sudo yum install -y nvidia-container-toolkit   sudo systemctl restart docker   For Debian based OSes  execute the following set of commands     Add the package repositories   distribution      etc os-release echo  ID VERSION ID    curl -s -L https   nvidia github io nvidia-docker gpgkey   sudo apt-key add -   curl -s -L https   nvidia github io nvidia-docker  distribution nvidia-docker list   sudo tee  etc apt sources list d nvidia-docker list    sudo apt-get update  amp  amp  sudo apt-get install -y nvidia-container-toolkit   sudo systemctl restart docker   Running the docker with GPU support  docker run --name my all gpu container --gpus all -t nvidia cuda   Please note  the flag --gpus all is used to assign all available gpus to the docker container   To assign specific gpu to the docker container  in case of multiple GPUs available in your machine   docker run --name my first gpu container --gpus device 0 nvidia cuda   Or  docker run --name my first gpu container --gpus   device 0   nvidia cuda

Recent enhancements by NVIDIA have produced a much more robust way to do this   Essentially they have found a way to avoid the need to install the CUDA GPU driver inside the containers and have it match the host kernel module   Instead  drivers are on the host and the containers don t need them  It requires a modified docker-cli right now   This is great  because now containers are much more portable     A quick test on Ubuntu     Install nvidia-docker and nvidia-docker-plugin wget -P  tmp https   github com NVIDIA nvidia-docker releases download v1 0 1 nvidia-docker 1 0 1-1 amd64 deb sudo dpkg -i  tmp nvidia-docker  deb  amp  amp  rm  tmp nvidia-docker  deb    Test nvidia-smi nvidia-docker run --rm nvidia cuda nvidia-smi   For more details see  GPU-Enabled Docker Container and  https   github com NVIDIA nvidia-docker

Regan s answer is great  but it s a bit out of date  since the correct way to do this is avoid the lxc execution context as Docker has dropped LXC as the default execution context as of docker 0 9    Instead it s better to tell docker about the nvidia devices via the --device flag  and just use the native execution context rather than lxc   Environment  These instructions were tested on the following environment    Ubuntu 14 04 CUDA 6 5 AWS GPU instance    Install nvidia driver and cuda on your host  See CUDA 6 5 on AWS GPU Instance Running Ubuntu 14 04 to get your host machine setup   Install Docker    sudo apt-key adv --keyserver hkp   keyserver ubuntu com 80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9   sudo sh -c  echo deb https   get docker com ubuntu docker main  gt   etc apt sources list d docker list    sudo apt-get update  amp  amp  sudo apt-get install lxc-docker   Find your nvidia devices  ls -la  dev   grep nvidia  crw-rw-rw-  1 root root    195    0 Oct 25 19 37 nvidia0  crw-rw-rw-  1 root root    195  255 Oct 25 19 37 nvidiactl crw-rw-rw-  1 root root    251    0 Oct 25 19 37 nvidia-uvm   Run Docker container with nvidia driver pre-installed  I ve created a docker image that has the cuda drivers pre-installed   The dockerfile is available on dockerhub if you want to know how this image was built   You ll want to customize this command to match your nvidia devices   Here s what worked for me      sudo docker run -ti --device  dev nvidia0  dev nvidia0 --device  dev nvidiactl  dev nvidiactl --device  dev nvidia-uvm  dev nvidia-uvm tleyden5iwx ubuntu-cuda  bin bash   Verify CUDA is correctly installed  This should be run from inside the docker container you just launched   Install CUDA samples     cd  opt nvidia installers     cuda-samples-linux-6 5 14-18745345 run -noprompt -cudaprefix  usr local cuda-6 5    Build deviceQuery sample     cd  usr local cuda samples 1 Utilities deviceQuery   make     deviceQuery      If everything worked  you should see the following output   deviceQuery  CUDA Driver   CUDART  CUDA Driver Version   6 5  CUDA Runtime Version   6 5  NumDevs      1  Device0   GRID K520 Result   PASS

Ok i finally managed to do it without using the --privileged mode   I m running on ubuntu server 14 04 and i m using the latest cuda  6 0 37 for linux 13 04 64 bits      Preparation  Install nvidia driver and cuda on your host   it can be a little tricky so i will suggest you follow this guide https   askubuntu com questions 451672 installing-and-testing-cuda-in-ubuntu-14-04   ATTENTION   It s really important that you keep the files you used for the host cuda installation    Get the Docker Daemon to run using lxc  We need to run docker daemon using lxc driver to be able to modify the configuration and give the container access to the device   One time utilization     sudo service docker stop sudo docker -d -e lxc   Permanent configuration Modify your docker configuration file located in  etc default docker Change the line DOCKER OPTS by adding  -e lxc  Here is my line after modification  DOCKER OPTS  --dns 8 8 8 8 --dns 8 8 4 4 -e lxc    Then restart the daemon using  sudo service docker restart   How to check if the daemon effectively use lxc driver    docker info   The Execution Driver line should look like that    Execution Driver  lxc-1 0 5     Build your image with the NVIDIA and CUDA driver   Here is a basic Dockerfile to build a CUDA compatible image   FROM ubuntu 14 04 MAINTAINER Regan  lt http   stackoverflow com questions 25185405 using-gpu-from-a-docker-container gt   RUN apt-get update  amp  amp  apt-get install -y build-essential RUN apt-get --purge remove -y nvidia   ADD   Downloads nvidia installers  tmp nvidia                              gt  Get the install files you used to install CUDA and the NVIDIA drivers on your host RUN  tmp nvidia NVIDIA-Linux-x86 64-331 62 run -s -N --no-kernel-module    gt  Install the driver  RUN rm -rf  tmp selfgz7                                                    gt  For some reason the driver installer left temp files when used during a docker build  i don t have any explanation why  and the CUDA installer will fail if there still there so we delete them  RUN  tmp nvidia cuda-linux64-rel-6 0 37-18176142 run -noprompt             gt  CUDA driver installer  RUN  tmp nvidia cuda-samples-linux-6 0 37-18176142 run -noprompt -cudaprefix  usr local cuda-6 0    gt  CUDA samples comment if you don t want them  RUN export LD LIBRARY PATH  LD LIBRARY PATH  usr local cuda lib64          gt  Add CUDA library into your PATH RUN touch  etc ld so conf d cuda conf                                      gt  Update the ld so conf d directory RUN rm -rf  temp     gt  Delete installer files      Run your image   First you need to identify your the major number associated with your device  Easiest way is to do the following command     ls -la  dev   grep nvidia   If the result is blank  use launching one of the samples on the host should do the trick  The result should look like that  As you can see there is a set of 2 numbers between the group and the date  These 2 numbers are called major and minor numbers  wrote in that order  and design a device  We will just use the major numbers for convenience   Why do we activated lxc driver  To use the lxc conf option that allow us to permit our container to access those devices  The option is    i recommend using   for the minor number cause it reduce the length of the run command       --lxc-conf  lxc cgroup devices allow   c  major number   minor number or    rwm    So if i want to launch a container  Supposing your image name is cuda    docker run -ti --lxc-conf  lxc cgroup devices allow   c 195   rwm  --lxc-conf  lxc cgroup devices allow   c 243   rwm  cuda
