This is a very simple Subsonic scrobbler for MPD.
It is not a LAST.FM or libre.fm scrobbler.
This scrobbler allows mpd to notify a subsonic server when it has played a song which has been server from that subsonic server. The subsonic server might, if configured, scrobble the song to LAST.FM, libre.fm, etc.
It might be useful when using the Subsonic plugin for Upmpdcli. See the discussion here.

Please see the Goal.
Please note that support goal is limited to cover running costs for subscriptions to music services.

Initially I used this docker repo. I then noticed that it was named differently from the github repo.
So I created a new docker hub repo here and updated the documentation.
The old docker hub repo will not receive updates of course. Please correct your docker compose/run so that they reference the correct image name.
Sorry for the inconvenience

Among those, mpd-alsa-docker and upmpdcli-docker provide a method for deploying mpd and upmpdcli using docker.

• linux/amd64
• linux/arm/v7
• linux/arm/v5
• linux/arm64/v8

The subsonic configuration parameters are required: either specificy the individual variables, or specify a SUBSONIC_PARAMETERS to indicate the file which will contain the parameters. The file must be accessible to the container. You can use the /config volume and put a file named, e.g. ".subsonic.env" there.
All the MPD_* (unless specified) and SUBSONIC_* variables can be suffixed with _1, _2, _3 etc in order to configure multiple mpd instances and multiple SubSonic servers.
Inside a single config file, even if it refer to an index > 0, the variable names must be specified without the index.

The following compose file creates a subsonic scrobbler for mpd-d10 (as it operates on a Topping D10 DAC) and mpd-d200 (as it operates on a Yulong D200 DAC), which are instances of mpd-alsa-docker running on the same host and specifically on the network mpd.
Subsonic config is read from a separate file.

---
version: "3"

networks:
  mpd:
    external: true

services:
  scrobbler:
    image: giof71/mpd-subsonic-scrobbler:latest
    container_name: subsonic-scrobbler-d10
    networks:
      - mpd
    environment:
      - MPD_HOST=mpd-d10
      - MPD_PORT=6600
      - MPD_HOST_1=mpd-d200
      - MPD_PORT_1=6600
      - SUBSONIC_PARAMETERS_FILE=/config/my-navidrome.env
      - SUBSONIC_PARAMETERS_FILE_1=/config/navidrome-demo.env
      - VERBOSE=0
    volumes:
      - ./my-navidrome.env:/config/my-navidrome.env:ro
      - ./navidrome-demo.env:/config/navidrome-demo.env:ro
    restart: unless-stopped

Same situation, without the separate file:

---
version: "3"

networks:
  mpd:
    external: true

services:
  scrobbler:
    image: giof71/mpd-subsonic-scrobbler:latest
    container_name: subsonic-scrobbler-d10
    networks:
      - mpd
    environment:
      - MPD_HOST=mpd-d10
      - MPD_PORT=6600
      - MPD_HOST_1=mpd-d200
      - MPD_PORT_1=6600
      - SUBSONIC_BASE_URL=${MY_NAVIDROME_BASE_URL}
      - SUBSONIC_PORT=${MY_NAVIDROME_PORT}
      - SUBSONIC_USER=${MY_NAVIDROME_USER}
      - SUBSONIC_PASSWORD=${MY_NAVIDROME_PASSWORD}
      - SUBSONIC_BASE_URL_1=${NAVIDROME_DEMO_BASE_URL}
      - SUBSONIC_PORT_1=${NAVIDROME_DEMO_PORT}
      - SUBSONIC_USER_1=${NAVIDROME_DEMO_USER}
      - SUBSONIC_PASSWORD_1=${NAVIDROME_DEMO_PASSWORD}
      - VERBOSE=0
    restart: unless-stopped

In this case, the configuration parameters are read from the .env file.
In order to avoid issues with password, which might contain special characters, it is better to not place such password on the compose file, and leverage the .env file instead.
