Not pretty, but it works just fine:
First Prototype: Replays audioHandles once to test sound output from rpi3 when running inside docker container via balena
Using, balena-cloud.io.
Therefore Dockerfile.template Doc: #dockerfile-templates
git push balena

to use git bash or minggw. Then do balena login and retry push to
balena remote
