My Mopidy Setup

This is the Docker image that I'm currently using to run Mopidy on a Raspberry Pi Zero with PhatDAC.

It probably won't be exactly the setup you want, but feel free to create a fork for your own setup.

Build on PC

docker build --pull -t jjok/mopidy --build-arg BUILD_FROM=debian:stable-slim .

Build on Raspberry Pi

docker build --pull -t jjok/mopidy --build-arg BUILD_FROM=balenalib/rpi-raspbian:latest .

Run in foreground:

docker run --rm \
           --name mopidy \
           --device /dev/snd \
           -p 6600:6600 -p 6680:6680 \
           -it \
           jjok/mopidy

Run in background:

docker run --restart=unless-stopped \
           --name mopidy \
           --device /dev/snd \
           -p 6600:6600 -p 6680:6680 \
           -d \
           jjok/mopidy

View logs:

docker logs -f mopidy

Execute any Mopidy command:

docker exec mopidy mopidy <cmd>
docker exec mopidy mopidy config
docker exec mopidy mopidy deps

Mount music from Samba share on network

sudo apt install samba samba-common-bin smbclient cifs-utils

echo "//192.168.1.1/share  /home/pi/music  cifs  guest,vers=1.0  0  0" | sudo tee -a /etc/fstab

Raspberry PI Setup

1. Burn Raspberry PI OS to SD card (8GB+). A 2GB SD card will not be big enough for both Raspbian and the Docker image.
2. Put SD card in Raspberry Pi 2. A Pi Zero does not have enough RAM to build the Docker image.
3. Install Docker CE. sudo apt install docker-ce
4. Copy Dockerfile, requirements.txt and mopidy.conf to the Pi.
5. Run build command (takes around 45 minutes on Pi 2)
6. Put SD card in Pi Zero
7. Run "Run in background" command
8. Install PhatDAC soundcard
9. Reboot
