This is a Dockerfile to set up OctoPrint. It supports the following architectures automatically:

• x86
• arm32v6 (Raspberry Pi, etc.)

• 1.3.6, latest (Dockerfile)
• master (Automatically built daily from OctoPrint's master branch)

$ docker run \
  --device=/dev/video0 \
  -p 80:80 \
  -v /mnt/data:/data \
  nunofgs/octoprint

Cura engine integration was very outdated (using version 15.04.6) and was removed.

It will return once OctoPrint supports python3 (needed for the newest versions of cura engine).

1. Bind the camera to the docker using --device=/dev/video0:/dev/videoX
2. If camera supports only MJPEG formatting, please set STREAMER_FLAGS to "" or something else.
3. Use the following settings in octoprint:

webcam:
  stream: /webcam/?action=stream
  snapshot: http://127.0.0.1:8080/?action=snapshot
  ffmpeg: /usr/bin/ffmpeg

This image uses supervisord in order to launch 3 processes: haproxy, octoprint and mjpeg-streamer.

This means you can disable/enable the camera at will from within octoprint by editing your config.yaml:

system:
  actions:
  - action: streamon
    command: supervisorctl start mjpeg-streamer
    confirm: false
    name: Start webcam
  - action: streamoff
    command: supervisorctl stop mjpeg-streamer
    confirm: false
    name: Stop webcam
