UID/GID in makefile for run-docker

[DrEStaudinger]

Hi everybody,

in the Makefile you have a docker run command as follows:

docker run -u $(id -u):$(id -g) -p 8888:8888 --privileged=true $(GPU) --env NVIDIA_DRIVER_CAPABILITIES=graphics,compute,utility --rm -it sionna

For me, the option -u $(id -u):$(id -g) does not work, as the returned IDs are empty.
Changing it to -u $(shell id -u):$(shell id -g) solves it.

Cheers,
Emanuel

Update:
As the default passed UID and GID are empty based on the original Makefile, the user inside the docker container is root. With this setting, e.g., the ray-tracing tutorial works.
By setting it to "shell id -u" etc. the correct UID and GID are passed on, but the scripts do not work anymore.
E.g., Sionna_Ray_Tracing_Introduction.ipynb:
The kernel dies, as Matplotlib creates an error on the first executed python script lines: "Matplotlib created a temporary cache directory ... because the default path (/.config/matplotlib) is not a writeable directory.

Best, Emanuel
