How to use nvidia-docker2 under gentoo

I fixed the nvidia-container-toolkit (aka. nvidia-docker2 ) issue under gentoo and got this working.

Due to historical reasons, the software supported by nvidia's docker has gone through a very messy period. About The difference between libnvidia-container, nvidia-docker2, nvidia-container-runtime, nvidia-container-toolkit, here is a good introduction.

Here only introduces how to use the new method in the Docker version after 19.03:

docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

cgroup v2

By default libnvidia-container and nvidia-container-toolkit equal or above version 1.8.0 support cgroup v2.

Systemd v247.2-2 introduced cgroup v2 which broken nvidia-container's access to /sys/fs/cgroup/devices. To solve this problem, you should upgrade both libnvidia-container and nvidia-container-toolkit equal or above version 1.8.0 to support cgroup v2.

If you don't want use the cgroup v2, you should add kernel parameter systemd.unified_cgroup_hierarchy=false.

If you don't want use the cgroup at all, you should change /etc/nvidia-container-runtime/config.toml with no-cgroups = true and need to run docker explicitly allow access to the nvidia devices, like:

docker run ... --gpus all \
    --device /dev/nvidia0 \
    --device /dev/nvidiactl \
    --device /dev/nvidia-modeset \
    --device /dev/nvidia-uvm \
    --device /dev/nvidia-uvm-tools

OpenRC

sudo layman --add=vowstar
sudo emerge -av nvidia-container-toolkit
sudo rc-service docker restart
docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

systemd

sudo layman --add=vowstar
sudo emerge -av nvidia-container-toolkit
sudo systemctl restart docker
docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

Result

$ docker run --gpus all nvidia/cuda:10.0-base nvidia-smi
