Ubuntu based image to run roon Server.
You will need to run this image as privileged and with net option host. This is tested on a Synology 1512 with 3GB RAM. On the Synology this image breaks working if stopped and started with the Docker package, so use the command line ( and use restart always).
So your command line should look like:
$ sudo docker run --name roon --privileged --restart=always --net="host" roon
