 # Bordanlage – Boat Onboard System

-A complete multiroom audio + navigation dashboard system for boats.
-Runs on any Docker-capable computer – fully simulated in dev mode (no hardware needed).
+Multiroom audio + navigation dashboard for boats.
+Full Docker stack — works on any machine, no hardware required in dev mode.

 ---

-## Prerequisites
+## Stack

- [Docker Desktop](https://www.docker.com/products/docker-desktop/) (or Docker Engine + Compose)
- `make`
- For Spotify Connect: a Spotify Premium account
+| Service | Image / Build | Purpose |
+|---|---|---|
+| SignalK | `signalk/signalk-server` | NMEA 0183/2000 gateway, WebSocket delta stream |
+| Snapserver | custom build (v0.35.0) | Multiroom audio server, JSON-RPC on :1705 |
+| zone-salon/cockpit/bug/heck | custom build (v0.35.0) | Audio zones (snapclient) |
+| Mopidy + Iris | custom Dockerfile | Local music, TuneIn radio, HTTP control on :6680 |
+| librespot | custom build (v0.5.0) | Spotify Connect receiver, pipe backend |
+| shairport-sync | `mikebrady/shairport-sync` | AirPlay 2 receiver, pipe backend |
+| Jellyfin | `jellyfin/jellyfin` | Media library, :8096 |
+| SignalK | `signalk/signalk-server` | Navigation data, demo NMEA in dev mode |
+| Portainer | `portainer/portainer-ce` | Docker management UI, :9000 |
+| Dashboard | React 18 + Vite | Touch UI, built with Vite (dev: HMR on :8090) |
+
+Audio flow: `librespot / shairport / mopidy` → named pipe (PCM) → `snapserver` → `snapclient` zones

 ---

-## Quick Start
+## Quick Start (Dev)

 ```bash
-cd bordanlage
 make dev
 ```

-Dashboard: **http://localhost:8080**
+Dashboard with hot-reload: **http://localhost:8090**
+
+On first run, Docker builds the custom images (snapserver, snapclient, mopidy, librespot stub). Subsequent starts are instant.
+
+### Mac audio output
+
+```bash
+make mac-audio   # runs snapclient natively via Homebrew → Mac speakers
+make spotify     # runs librespot natively via Homebrew → Spotify Connect on Mac
+```
+
+Both commands require `brew install snapcast` / `brew install librespot` (auto-installed if missing).

+```
+
+---
+
 ## Spotify Connect

-1. Run `make dev` (or `make boot` on the boat)
-2. Open Spotify on your phone/computer
-3. Tap the device icon (bottom right) → look for **"Bordanlage"**
-4. If it doesn't appear automatically: Go to **Connect to a Device** → enter the IP of the host machine manually
+**Dev mode (Mac):** run `make spotify` — shows as "Bordanlage" in Spotify app.

-> On Linux (boat): set `network_mode: host` for the `librespot` service in `docker-compose.yml` for reliable mDNS discovery.
+**Boot mode (boat):** librespot runs inside Docker, pipe backend, writes PCM to `/tmp/audio/spotify.pcm`.
+
+> On Linux (boat), set `network_mode: host` for `librespot` and `shairport` in `docker-compose.yml` for reliable mDNS/Bonjour discovery.

 ---

 ## AirPlay

-1. Ensure the `shairport` container is running
-2. On your iPhone/Mac: open Control Center → tap AirPlay → select **"Bordanlage AirPlay"**
+The `shairport` container runs `shairport-sync` with pipe output.

-> On Mac: AirPlay works natively via Bonjour.
-> On Windows WSL2: the `avahi` container in `docker-compose.dev.yml` handles mDNS.
+1. On iPhone/Mac: Control Center → AirPlay → select **"Bordanlage AirPlay"**
+2. Audio goes through the snapserver multiroom pipeline
+
+Config: `config/shairport.conf`

 ---

-## Adding Music
+## Adding Music (Mopidy)

-Drop audio files into `./music/`. Mopidy and Jellyfin both mount this directory.
+Drop files into `./music/`. Trigger a library scan:

-Trigger a Mopidy library scan:
 ```bash
-curl -s http://localhost:6680/mopidy/rpc -d '{"jsonrpc":"2.0","id":1,"method":"local.scan"}' \
-  -H "Content-Type: application/json"
+curl -s http://localhost:6680/mopidy/rpc \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","id":1,"method":"local.scan"}'
 ```

-For Jellyfin: open http://localhost:8096 → Settings → Libraries → Scan.
-
 ---

-## Connecting Real NMEA Hardware
+## Zones

-Edit `docker-compose.yml` and uncomment the `signalk` device section:
+Four zones are pre-configured:

-```yaml
-signalk:
-  devices:
-    - /dev/ttyUSB0:/dev/ttyUSB0  # NMEA 0183 via USB-Serial
-```
+| Zone | hostID | Production use |
+|---|---|---|
+| Salon | zone-salon | Below-deck salon speakers |
+| Cockpit | zone-cockpit | Cockpit/helm area |
+| Bug | zone-bug | Forward cabin (Bug = bow in German) |
+| Heck | zone-heck | Stern (Heck = stern in German) |

-Then configure the NMEA connection in SignalK at http://localhost:3000 → Server → Connections.
-
-For NMEA 2000: use a Yacht Devices YDNU-02 or similar USB gateway.
+Each zone runs `snapclient` connecting to `snapserver` on the Docker internal network.
+In dev mode the zones use `--player file:filename=null` (audio discarded, no hardware needed).
+In production, replace with `--player alsa --soundcard hw:N,0` and expose `/dev/snd`.

 ---

-## Migration to Real Boat
+## Environment Variables

-Changes needed in `docker-compose.yml`:
+Copy `.env.example` to `.env` and adjust:

-1. **Audio output per zone**: add `--soundcard hw:N,0` to each `zone-*` command and uncomment `/dev/snd`
-2. **Spotify/AirPlay discovery**: set `network_mode: host` for `librespot` and `shairport`
-3. **Hardware video decoding** (optional): uncomment `/dev/dri` in `jellyfin`
-4. **NMEA hardware**: uncomment `/dev/ttyUSB0` in `signalk`
-5. Set `DEV=false` in `.env`
+```
+SPOTIFY_NAME=Bordanlage
+SPOTIFY_BITRATE=320
+MUSIC_PATH=./music
+VITE_USE_MOCK=false     # true = force mock data in dashboard, false = real APIs
+```

-Run `make boot` instead of `make dev`.
+---
+
+## Dashboard API Configuration
+
+The dashboard reads hosts from environment at build time:
+
+| Variable | Default | Description |
+|---|---|---|
+| `VITE_SNAPCAST_HOST` | `localhost` | Snapserver hostname |
+| `VITE_SIGNALK_HOST` | `localhost` | SignalK hostname |
+| `VITE_MOPIDY_HOST` | `localhost` | Mopidy hostname |
+| `VITE_JELLYFIN_HOST` | `localhost` | Jellyfin hostname |
+| `VITE_USE_MOCK` | `false` | Force mock data (no real APIs) |
+
+---
+
+## Architecture: Named Pipes
+
+In **boot mode**, audio flows through named pipes on a tmpfs volume:
+
+```
+spotify.pcm   ← librespot  (Spotify Connect)
+airplay.pcm   ← shairport  (AirPlay 2)
+mopidy.pcm    ← mopidy     (local files, radio)
+```
+
+Snapserver reads all three as streams and routes them to zones.
+
+Run `make pipes` once before `make boot` to create the pipes (or they are created automatically).
+
+In **dev mode**, pipes are not used (no audio hardware crosses the Docker VM boundary on Mac).
+
+---
+
+## Migrating to the Boat
+
+Changes in `docker-compose.yml`:
+
+1. **Zone audio output** — replace `--player file:filename=null` with `--player alsa --soundcard hw:N,0`, uncomment `/dev/snd` device
+2. **Spotify / AirPlay discovery** — set `network_mode: host` for `librespot` and `shairport`
+3. **NMEA hardware** — uncomment the `devices` block under `signalk`, configure the connection at http://[boat-ip]:3000
+4. **Video decoding** (optional) — uncomment `/dev/dri` under `jellyfin`
+5. Use `make boot` instead of `make dev`

 ---

 ## Troubleshooting

-**Spotify device not showing up on Mac:**
- Ensure port 57621 (UDP+TCP) is accessible. Docker Desktop on Mac sometimes blocks UDP.
- Try connecting manually: Spotify → "Connect to a Device" → "Connect to [IP]"
+**Zones stuck restarting:**
+- Check `docker compose logs zone-salon`. With snapclient v0.35+, the server URI must be `tcp://snapserver` (not `--host snapserver`).
+- If "No audio player support": snapclient needs `--player file:filename=null` in dev (null player not compiled in the bookworm .deb).

-**AirPlay not visible on Windows:**
- The `avahi` container requires D-Bus. Run Docker Desktop with host networking or use WSL2.
+**Dashboard crashes with exit 127 / npm not found:**
+- The local `node:20-alpine` image was overwritten by the production dashboard build. Fix: `docker rmi node:20-alpine && make dev`.
+- Root cause prevented by `dashboard/Dockerfile.dev` — dev uses its own build context.

-**Snapcast zones show as offline:**
- Audio pipes must exist before snapserver starts. Run `make pipes` or `bash scripts/init-pipes.sh`
+**Shairport config syntax error:**
+- Boolean values in `config/shairport.conf` must be quoted: `"yes"` not `yes`.

-**Mopidy won't start:**
- Check `docker compose logs mopidy`. The custom Dockerfile installs plugins on first build; rebuild with `make rebuild`
+**Spotify device not visible:**
+- On Mac, Docker Desktop bridges UDP poorly. Use `make spotify` (native librespot on Mac) for dev.
+- On boat: use `network_mode: host` in `docker-compose.yml`.

-**Dashboard shows "No signal":**
- In dev mode this is normal until mock data initializes (1–2 seconds)
- In production: check that SignalK is running and the WebSocket URL is correct in `.env`
+**Librespot production build fails:**
+- `cargo install librespot` (latest = v0.8.0) has a vergen_lib dependency conflict.
+- Fixed by pinning to `--version "=0.5.0"` in `docker/librespot/Dockerfile`.

-**Port conflicts:**
- Edit the port mappings in `docker-compose.yml` or `docker-compose.dev.yml`
+**Snapcast arm64 .deb not found:**
+- v0.27.0 has no arm64 release. Use v0.35.0 which ships `arm64_bookworm.deb`.
+
+**Port conflicts (e.g. 8080 taken by Supabase):**
+- Dev dashboard is on **8090**, production on 8080. Change port mappings in `docker-compose.dev.yml` as needed.
