【RPi】Navidrome を動かす

はじめに

たくさんのWAVファイルを管理したいなー、と思って調べたら、Navidromeに出会いました。
ラズパイで動かしてみました。
Gemini先生に教えてもらっただけなのですが。メモ。

行ったこと

ラズパイへの接続

ラズパイは優先で自宅のLANに接続された状態なので、IPアドレスを知りたかった。Windows ノートPCで下記を実行

# 1. ネットワーク範囲の自動取得
$ipPrefix = (Get-NetIPAddress -InterfaceAlias "Wi-Fi" -AddressFamily IPv4).IPAddress -replace '\\.\\d+$','.'
if (-not $ipPrefix) {
     Write-Host "Wi-FiのIPアドレスが取得できませんでした。" -ForegroundColor Red
} else {
    Write-Host "現在のネットワーク (${ipPrefix}x) をスキャン中..." -ForegroundColor Cyan
    Write-Host "※30秒〜1分ほどかかります。そのままお待ちください..." -ForegroundColor Yellow

# 2. 従来のPowerShellに対応した速度優先のPing送信
1..254 | ForEach-Object {
         $ip = "$ipPrefix$\_"
         \[System.Net.NetworkInformation.Ping]::new().SendAsync($ip, 100) | Out-Null
}
# 3. 少し待ってからARPテーブルからラズパイを抽出
Start-Sleep -Seconds 2
     Write-Host "`n\[発見したRaspberry PiのIPアドレス一覧]" -ForegroundColor Green
     arp -a | Select-String -Pattern "b8-27-eb", "dc-a6-32", "e8-16-56", "d8-3a-dd"
}

見つかった。

現在のネットワーク (192.168.3.x) をスキャン中...
※30秒〜1分ほどかかります。そのままお待ちください...

\[発見したRaspberry PiのIPアドレス一覧]

  192.168.3.16          dc-a6-32-93-61-b7     動的

SSH でラズパイに入ってDocker を用意

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.


To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker.com/go/attack-surface/

================================================================================

pi@tp3:~/audio_server $ sudo usermod -aG docker $USER
pi@tp3:~/audio_server $ newgrp docker
pi@tp3:~/audio_server $ docker -v
Docker version 28.5.2, build ecc6942

Navidrome を起動

下記の compose.yaml ファイルを作る。

compose.yaml

services:
  navidrome:
    image: deluan/navidrome:latest
    user: 1000:1000 # must own the data folder and be able to read music folder(s). See Permissions below
    ports:
      - "4533:4533"
    restart: unless-stopped
    environment:
      ND_LOGLEVEL: info
      TZ: Asia/Tokyo
    volumes:
      - "/home/pi/audio_server/data:/data"
      - "/home/pi/Music/:/music:ro"

起動する。

設定

Dockerに渡す環境変数や設定ファイルを使うことができるようです。
詳しくは下記に書いてあります。

environment:
      TZ: Asia/Tokyo
      ND_LOGLEVEL: info
      ND_SCANSCHEDULE: "@every 1h"          # 1時間ごとにフォルダを自動スキャン
      ND_ALBUMPLAYLISTSORT: "tracknumber"   # プレイリストやアルバム内の曲順をトラック番号順に
      ND_DEFAULTLANGUAGE: "ja"              # Web UI のデフォルト言語を日本語に固定
      ND_ENABLETRANSCODINGCONFIG: "true"   # Web UI からトランスコード（ビットレート制限）設定を可能にする
      ND_ENABLESHARING: "true"             # 外部共有用の公開リンク作成機能を有効化
      ND_UIFULLWIDTH: "true"               # Web UI を画面横幅いっぱいに表示

WebAPIも使えるようですが、swagger を表示しようとしたらうまくできませんでした。AIの答えも正しくなく、少し最新の情報を調べる必要がありそうでした。

まとめ

とりあえず、ラズパイでNovidrome が動きました。
