This runs a motion-detecting camera connected to a Raspberry Pi. The videos are saved into a folder on the host machine (i.e. outside of the Docker container), and can be streamed over the network too.
docker build . -t lazyatom/rpi-motion
If you're happy with the defaults, you can run this using the included script:
./run.sh
This will connect to a webcam via /dev/video0, create and mount the video directory in a directory called videos within the current cdirectory, and start running as a daemon.
If you need anything more customized, then you can use the commands inside run.sh as the basis for that.
