Synology Docker Beets install help


I am trying to install Beets in my Synology 918+ using Docker, but I am a complete noob on Docker.

So far, I cannot really follow the listed steps and cant find anything on the net as a quck how to for this particular configuration.

Steps done:

1- Grab container from the docker listing.
2- Create a folder for the container to hold its configuration (storage/docker/beets)
3- Create container, point it to that folder.
4- change network settings to same as host.

Thats where I’m stuck, since I dont know where to go to set any variables, like Dump music folder and fixed music folder, the so called config.yaml file is nowhere to be found.

Please help!
