raspberry pi 3 GPIO
not sure if this is even possible, relatively new to containers/docker. i am trying to use the GPIO pins from with the container to activate a switch, similar to documented here https://spin.atomicobject.com/2017/08/27/siri-homekit-raspberry-pi-software/. is it possible to access/control the gpio from within the container? most options seem to require https://pypi.python.org/pypi/RPi.GPIO but im unable to pip install or yarn add within the container?
