BalenaSound support

Hello,

I wonder if some of you have ever try to install modipy on BalenaSound balenalabs/balena-sound#215
it relies on Balena Cloud.
My use case would be to cast webradios listed on Radio-Browser through RadioDroid Android application to a Raspberry Pi 2 model B (which doesn’t have bluetooth support).
Balena Cloud seems to work with Docker… and more exactly with docker-compose.
Unfortunately I’m currently not a Docker specialist to make my own docker-compose file for Mopidy.
Any help will be great!

Kind regards
