Raspberry Pi Zero 2 + Raspbian 12 Bookworm + Camera Module 3 + Octoprint Docker

[rdustinb]

Hi everyone!

Has anyone had success with the combination of a RPi Zero 2, Raspbian 12, Camera Module 3, and Octoprint Docker?

Host Camera Detection

The host system can see the camera and using:

rpicam-hello -n

the result is:

[51:56:35.154460342] [18371]  INFO Camera camera_manager.cpp:327 libcamera v0.4.0+53-29156679

I can also generate a snapshot image using rpicam-hello, from the Camera Module 3, so the hardware and host system setup seems ok.

Docker Configuration

I am using the following docker compose configuration:

octoprint:
  container_name: octoprint
  image: octoprint/octoprint:latest
  restart: unless-stopped
  ports:
    - '80:80'
    - '8080:8080'
  devices:
    - '/dev/ttyUSB0:/dev/ttyUSB0'
    - '/dev/video0:/dev/video0'
  volumes:
    - '~/volumes/octoprint:/octoprint'
  environment:
    - 'TZ=America/Denver'
    - 'ENABLE_MJPG_STREAMER=true'
    - 'CAMERA_DEV=/dev/video0'            
    - 'MJPG_STREAMER_INPUT=-r 1536x864 -f 10'

Debug

The video0 device seems correct, since when I have the docker container running and I try to run rpicam-hello again, I get an error saying the camera device is busy:

docker compose up -d octoprint
rpicam-hello -n

results in:

When the container starts up, it prints several errors pertaining to the video device that I can see, though maybe these won't cause the issues I am seeing (er...NOT seeing, haha):
