I created Mopidy docker image to utilize network audio server with my audio collection

Docker is hosted on OrangePi Zero mini computer. I will not cover docker configuration since it is not part of the project.

Sources can be found here

To install this as a service create file /etc/systemd/system/mopidy-docker.service with following content (please change settings where necessary)

[Unit]
Description=dockerized mopidy
Requires=docker.service

[Install]
WantedBy=multi-user.target

then execute 

sudo systemctl daemon-reload
sudo systemctl start mopidy-docker.service

if you see it is running OK and available at http://host:6680 enable service startup

sudo systemctl start mopidy-docker.service
