docker-python is a simple flask server app loaded into Rpi via Balena
python-env-docker is an example of getting .env parameter values via a python script with balena loading the image into the Rpi
Next step: A simple bash script running in the Rpi that can access the .env parameters.
Eventually: (1) Install pisound drivers and then (2) build orcanode
The orcanode-balena directory has a working Dockerfile docker-compose.yml set of files.
You do need a .env file with the AWS keys and NODE_NAME etc.
