Docker Desktop における GPU サポート

メモ

現時点において Docker Desktop における GPU サポートは、WSL2 バックエンドを使った Windows 上においてのみ利用可能です。

WSL2 のもとでの NVIDIA GPU の利用

Docker Desktop for Windows supports WSL 2 GPU Paravirtualization (GPU-PV) on NVIDIA GPUs. To enable WSL 2 GPU Paravirtualization, you need:

  • A machine with an NVIDIA GPU
  • Up to date Windows 10 or Windows 11 installation
  • Up to date drivers from NVIDIA supporting WSL 2 GPU Paravirtualization
  • The latest version of the WSL 2 Linux kernel. Use wsl --update on the command line
  • To make sure the WSL 2 backend is turned on in Docker Desktop

To validate that everything works as expected, execute a docker run command with the --gpus=all flag. For example, the following will run a short benchmark on your GPU:

$ docker run --rm -it --gpus=all nvcr.io/nvidia/k8s/cuda-sample:nbody nbody -gpu -benchmark

The output will be similar to:

Run "nbody -benchmark [-numbodies=<numBodies>]" to measure performance.
        -fullscreen       (run n-body simulation in fullscreen mode)
        -fp64             (use double precision floating point values for simulation)
        -hostmem          (stores simulation data in host memory)
        -benchmark        (run benchmark to measure performance)
        -numbodies=<N>    (number of bodies (>= 1) to run in simulation)
        -device=<d>       (where d=0,1,2.... for the CUDA device to use)
        -numdevices=<i>   (where i=(number of CUDA devices > 0) to use for simulation)
        -compare          (compares simulation results running once on the default GPU and once on the CPU)
        -cpu              (run n-body simulation on the CPU)
        -tipsy=<file.bin> (load a tipsy model file for simulation)

Or if you wanted to try something more useful you could use the official Ollama image to run the Llama2 large language model.

$ docker run --gpus=all -d -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama
$ docker exec -it ollama ollama run llama2
