Raumserver is a HTTP REST API nodeJs library for controling the Raumfeld Multiroom System via simple HTTP commands.
(see https://github.com/ChriD/node-raumserver).
Search for docker-raumserver and install it.
You have to use net=--host
for the container, otherwise the raumserver will not find any devices.
Docker raumserver will reside on port 8585
Currently it works well on a QNAP NAS but not on any Windows Docker installation
Use 'net=--host' !!!
