Use GPU support in docker container

[SimonBard]

What do I need to do to use the GPU in the recognize app?
My nextcloud is running in a docker container.

The drivers are installed correctly and they can be accessed from docker container in general. Just nextcloud does not want to activate the feature for gpu support:

$ docker run --gpus all nvidia/cuda:11.0.3-base-ubuntu20.04 nvidia-smi

Can I check somehow if driver etc are installed correctly?
