balenaOS with spotifyd service - Spotify streamer.

balenaHub
1

Hello,
After using balena sound for 4 month GitHub - balena-io-experimental/balena-sound: Build a single or multi-room streamer for an existing audio device using a Raspberry Pi! Supports Bluetooth, Airplay and Spotify Connect I am force to look for alternative as it does lags & Interrupts randomly.
My device is Raspberry Pi3

Becasue of above I trying to build a Release at balenaCloud with Spotifyd as container/service.
However I do face problems, let start for begining.
This is how my project structure does looks like:
spotify-balena/
├── .gitignore
├── docker-compose.yml
└── spotifyd/
├── Dockerfile.template
└── start.sh

my docker-compose.yml contains:

version: '2.4'

services:
  spotifyd:
    build: ./spotifyd  # Ścieżka do katalogu z Dockerfile
    container_name: spotifyd
    restart: unless-stopped
    network_mode: host
    privileged: true
    environment:
      - SPOTIFY_USERNAME=${SPOTIFY_USERNAME}
      - SPOTIFY_PASSWORD=${SPOTIFY_PASSWORD}
      - SPOTIFY_DEVICE_NAME=RaspberryPi
      - SPOTIFY_BITRATE=160
      - SPOTIFY_BACKEND=alsa
      - SPOTIFY_DEVICE=hw:0
    labels:
      io.balena.features.dbus: '1'

my docker-template.file

FROM balenalib/raspberrypi3-debian:latest

RUN chmod +x /usr/local/bin/start.sh

# Ustawienie punktu wejścia

and start.sh

#!/bin/bash
/spotifyd/target/release/spotifyd \
    --username "$SPOTIFY_USERNAME" \
    --password "$SPOTIFY_PASSWORD" \
    --device-name "$SPOTIFY_DEVICE_NAME" \
    --bitrate "$SPOTIFY_BITRATE" \
    --backend "$SPOTIFY_BACKEND" \
    --device "$SPOTIFY_DEVICE"

it does build sucesfully however SpotifyD doesn’t start giving following errors:

 spotifyd  /usr/bin/spotifyd: line 1: Not: command not found
Service exited 'spotifyd sha256:aa55e81a0c4b412e879493702edffa43a2082eec35298fb5c300a400389b431a'
