PermissionError(13, 'Permission denied') when using unixconn.py in a container

General
1

Hello,

I think the issue is trying to launch unixconn.py inside a container however I will show all the process:

I have built a docker image (following this instructions: Ingesting Maps in a CARLA package - CARLA Simulator).

I have then created a container using:
sudo docker create -it --name unreal_carla --privileged -e SDL_VIDEODRIVER=x11 -e DISPLAY=$DISPLAY -e XAUTHORITY=$XAUTHORITY -v /tmp/.X11-unix:/tmp/.X11-unix -v $XAUTHORITY:$XAUTHORITY --gpus ‘all,“capabilities=graphics,utility,display,video,compute”’ -v $(pwd)/src:/add_map -v /var/run/docker.sock:/var/run/docker.sock carla bash

Then in this container I have tried to launch ~/carla/Util/Docker$ python3 docker_tools.py --input /add_map/input_folder --output /add_map/output_folder --packages map_package

And I got the following error:

Params:

  • Output path: /add_map/output_folder
  • Packages: map_package
  • Input path: /add_map/input_folder
  • Verbose: False
