Docker image of OpenCV 3 for ARM
Docker image for OpenCV 3 with Python3 and FFMPEG with x264 enabled. Based on resin/rpi-raspbian:jessie
Take a look at the docker-compose example.
This image lacks of an X11 environment so you cannot use createWindow or waitKey functions
You can create a container with access to your webcam by just writing in Linux:
docker run -it --privileged --device /dev/video0:/dev/video0 fradelg/rpi-opencv python3
This should launch the python interpreter so you can play with OpenCV API
