Run a Snapcast server with Spotify support as a Docker container.

This is a multi-arch image currently working on the amd64 and armhf platforms. This means you can use the same image regardless of platform.

Note: You need a Spotify premium account.

Run it like this (on your PC or ARM-based device):

docker run -d --name snapserver --net host -e DEVICE_NAME=Snapcast mazzolino/librespot-snapserver

That will make the device available to all Spotify clients in your network. Add your Spotify credentials in order to limit control to clients logged in with your account:

docker run -d --name snapserver --net host -e DEVICE_NAME=Snapcast -e USERNAME=my-spotify-username -e PASSWORD=my-spotify-password mazzolino/librespot-snapserver

Now you can connect your snapclient to your host's ip. The receiver should show up in Spotify under the DEVICE_NAME given above (e.g. Snapcast). Have fun playing music!

If you want to configure the snapcast server differently, you can mount your own snapserver.conf into the container:

docker run -d --name snapserver --net host -v /path/to/your/snapserver.conf:/etc/snapserver.conf:ro mazzolino/librespot-snapserver

NOTE: The configuration file needs to be mounted read-only for this to work.

Make sure to include a Spotify source in your configuration, like this:

[stream]
source = librespot:///librespot?name=Spotify&devicename=DEVICE_NAME&bitrate=320&volume=100&username=USERNAME&password=PASSWORD

(Replace DEVICE_NAME, USERNAME and PASSWORD accordingly.)

In order to build images for the non-amd64 architectures, you need to build on amd64 machine and enable qemu binfmt support. The easiest way for this is to run:

docker run --privileged --rm tonistiigi/binfmt --install all

The following command will build the images for all supported architectures. Replace my/image with your own image name:

docker buildx build --platform=linux/amd64,linux/arm/v7,linux/arm64 -t my/image --load .

To build only an image for the current architecture, run:

docker buildx build -t my/image --load .
