OctoPrint

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

• x86
• arm32v6 (Raspberry Pi, etc.)

Tags

• 1.3.11, latest (Dockerfile)
• 1.3.10 (Dockerfile)
• 1.3.9 (Dockerfile)
• 1.3.8 (Dockerfile)
• 1.3.7 (Dockerfile)
• 1.3.6 (Dockerfile)
• master (Automatically built daily from OctoPrint's master branch)

Tested devices

Device	Working?
Raspberry Pi 2b	✅
Raspberry Pi 3b+	✅
Raspberry Pi Zero W	❌

Usage

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

Environment Variables

Variable	Description	Default Value
CAMERA_DEV	The camera device node	/dev/video0
MJPEG_STREAMER_AUTOSTART	Start the camera automatically	true
STREAMER_FLAGS	Flags to pass to mjpg_streamer	-y -n -r 640x480

CuraEngine integration

Cura engine integration was very outdated (using version 15.04.6) and was removed.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

Webcam integration

1. Bind the camera to the docker using --device=/dev/video0:/dev/videoX
2. Optionally, change STREAMER_FLAGS to your preferred settings (ex: -y -n -r 1280x720 -f 10)
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

Notes

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
