## 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](https://github.com/NVIDIA/nvidia-docker/issues/1268).
Here only introduces how to use the new method in the Docker version after 19.03:
```bash
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:
```bash
docker run ... --gpus all \
--device /dev/nvidia0 \
--device /dev/nvidiactl \
--device /dev/nvidia-modeset \
--device /dev/nvidia-uvm \
--device /dev/nvidia-uvm-tools
```
### OpenRC
```bash
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
```bash
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
```text
$ docker run --gpus all nvidia/cuda:10.0-base nvidia-smi
