Cant access camera through docker 22.04 image

[excadigger]

I have a raspberry pi5 with the default OS. I could not run ROS2 humble on it so I have a docker container with ubuntu 22.04. Humble runs on it and I have gotten Lidar data to my laptop after some trial and error. The last piece of the puzzle is to get video, so I have bought a pi camera and it works without the docker container. Whenever I use the docker container though, I get the following:

root@Andy:/home/pi/libcamera# libcamera-hello -v

I have tried to run with privilege, mount the whole dev onto the container and change the cgroup:

docker run -it --rm --privileged \
--device-cgroup-rule='c 81:* rwm' \
--net=host \
-v /dev:/dev \
my_ros_image

I cant find anything online that helps. So does anyone know? Or have a smart way of bypassing the problem? I am able to stream from the pi5 to my laptop, and then create a ros node there, but there is like a 3 second lag when I use 540 x 720 and that wont work for a real time robot.

Hi,
I'm having the exact same issue.
I can interact with the camera in the host, but get the "ERROR: *** no cameras available ***" message in docker.

Did you had any luck with that ?
