My Mopidy Setup

These is the Docker images that I'm currently using to run Mopidy and Snapserver on a Raspberry Pi 3a, and Snapclient with a PhatDAC or IQAudio Pi-DACZero on a Raspberry Pi Zero.

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

The Mopidy version and all extensions to be installed are defined in requirements.txt.

I have music files in ~/music that I mount into the container.

Build

Build on PC

docker compose build mopidy snapserver --build-arg BUILD_FROM=docker.io/debian:bookworm-slim --build-arg ARCH=amd64

Build on Raspberry Pi (takes about 40 minutes on Pi 3)

docker compose build mopidy snapserver

Run Mopidy and Snapserver

docker compose up mopidy snapserver -d

Run Snapclient

docker compose up snapclient -d

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

Raspberry PI Setup

Mopidy and Snapcast

1. Burn Raspberry PI OS to SD card (16GB+). Put SD card in Raspberry Pi.
2. Copy files to the Pi. make upload-snapserver

• snapserver
• docker-compose.yml
• Dockerfile
• Makefile
• mopidy.conf
• requirements.txt

3. ssh onto Pi
4. Install Docker CE.
5. Run the build command
6. Mount music from USB (see below)
7. Run container docker compose up mopidy snapserver -d
8. Reboot
9. Scan for music docker exec mopidy mopidy local scan

Snapclient

1. Install Raspberry Pi OS
2. Copy files to the Pi.
   • make client=office upload
   • make client=kitchen upload
3. ssh onto Pi
4. Install Docker CE
5. Run docker compose build snapclient
6. Install soundcard (see below)
7. Reboot
8. Run container docker compose up snapclient -d

Install PhatDAC

https://learn.pimoroni.com/tutorial/phat/raspberry-pi-phat-dac-install

Their install script doesn't work for Raspberry Pi OS Bookworm. I managed to get it working.

Edit /boot/firmware/config.txt.

Remove this line:

dtparam=audio=on

Add this line:

dtoverlay=hifiberry-dac

Maybe enable I2C or something in raspi-config?

Install IQaudIO Pi-DACZero

https://github.com/iqaudio/UserDocs/blob/master/userguide.pdf

Edit /boot/firmware/config.txt.

Remove this line:

dtparam=audio=on

Add this line:

dtoverlay=iqaudio-dacplus

Mount music from USB

mkdir ~/usb
mkdir ~/music

Add these lines to /etc/fstab.

/dev/sda1                  /home/jonathan/usb    vfat   defaults         0   0
/home/jonathan/usb/music   /home/jonathan/music  none   defaults,rbind   0   0
