The page provides my ongoing work on Brayns

Using braynsViewer from Docker container

Purpose is to make braynsViewer runs in a container and use both X server and Nvidia driver of the host

Use X server on the host

To execute firefox from within a container, the following packages are required:

apt-get install -y mesa-utils libgl1-mesa-glx

Then the container can be started with the command below:

xhost +
docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY --rm -ti --entrypoint bash <IMAGE> -c firefox

Use nvidia-docker

nvidia-docker seems to be the proper tool to provide GPU capabilities to a container https://github.com/NVIDIA/nvidia-docker

To test installation: https://www.pugetsystems.com/labs/hpc/Docker-and-NVIDIA-docker-on-your-workstation-Using-Graphical-Applications-915/

Current issue

nvidia-docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY --rm -ti --entrypoint bash <IMAGE> -c braynsViewer
