Docker部署Discord.js+Distube音乐机器人时长显示00:00问题

我用Distube和Discord.js开发了一款音乐机器人，在Powershell中运行时可正常播放音乐，但通过Docker构建镜像并部署容器后，机器人无法获取歌曲信息，曲目时长显示为00:00并自动跳过当前曲目。我尝试更换distube@3.3.4及更早版本，问题仍未解决。

Dockerfile #

FROM node:alpine

WORKDIR /usr/app/

COPY package*.js ./

COPY ./ ./

RUN apk add --update python3 make g++ && rm -rf /var/cache/apk/*

RUN npm rebuild

RUN npm install

CMD ["node", "shard.js"]

问题截图：

1. 修复Dockerfile依赖与配置错误 #

Alpine镜像默认缺少yt-dlp运行所需的系统依赖，且原Dockerfile存在package*.js的拼写错误（应为package*.json），修改后的Dockerfile如下：

FROM node:alpine

WORKDIR /usr/app/

# 添加系统级依赖：ffmpeg用于媒体处理，ca-certificates用于HTTPS请求验证
RUN apk add --no-cache ffmpeg ca-certificates python3 make g++ && rm -rf /var/cache/apk/*

COPY package*.json ./
RUN npm install
COPY ./ ./

CMD ["node", "shard.js"]

2. 确保Distube的yt-dlp插件配置正确 #

在机器人代码中显式配置yt-dlp插件，保证能正常拉取歌曲信息：

const { DisTube } = require('distube');
const { YtDlpPlugin } = require('@distube/yt-dlp');

const distube = new DisTube(client, {
  plugins: [new YtDlpPlugin({
    ytdlOptions: {
      quality: 'highestaudio',
      highWaterMark: 1 << 25,
      // 强制启用信息获取
      getInfo: true
    }
  })]
});

3. 验证容器网络连通性 #

确保Docker容器可正常访问外部网络（如YouTube、Spotify的API），若服务器有防火墙或代理，需配置容器的网络策略，允许出站HTTP/HTTPS请求。

4. 清理缓存重新构建镜像 #

执行以下命令清理旧缓存与镜像，重新构建部署：

docker system prune -a
docker build -t music-bot .
docker run music-bot
