Dockerized the headphones music management software (https://github.com/rembo10/headphones).
I mount my NAS to my Docker host at /mnt/media, which is the destination for my music downloads.
Headphones still requires some configuration once the container is up and running.
docker run --name="headphones" -p 8888:8181 -v /data/warehouse/headphones:/data -v /mnt/media:/mnt/media -d kgizzi/headphones
Note: headphones uses port 8181, but since that is already in use on my Docker host I chose port 8888.
