[Realtime] Add Dockerfile compatible with Nvidia GPUs

[NFSS10]

Issue

• https://github.com/ripe-tech/platforme-realtime/issues/2737

Dependencies

• None

Decisions

• Create Dockerfile that supports Nvidia GPU passthrough

NOTE:

• There may be room for improvements because the base of this dockerfile is fairly large and probably there is room to remove some stuff that may not be needed;
• You need to do GPU passthrough when running the container:

docker run --gpus all my-image

---

Running

python manage.py model_viewer_test "[3, 7]" --headless --screenshots
