Ruby on rails Dockrise rails/redis/sidekiq/postgres项目

我正在尝试使用sidekiq、icecast和redis对rails应用程序进行dockerize，以进行流式处理。目前，我陷入了一个错误，我已经搜索了很长一段时间来找出。 错误回溯：

Dockerfile（有点乱，请容忍我）

我如何可能修复此getaddrinfo错误？我认为这是sidekiq和redis之间的某种连接错误。 我的sidekiq.rb配置文件中也有这个

 Sidekiq.configure_server do |config|
      config.redis = { url: 'redis://redis:6379' }
    end

提前谢谢。如果我的帖子有点模棱两可，我很抱歉。请随便问任何问题。：）

编辑：我使用这个sidekiq.rb文件部署了基础Rails应用程序（可以在端口localhost:3000上侦听），但现在我遇到了这个错误

web_1  | /usr/local/bundle/gems/redis-4.0.1/lib/redis/connection/ruby.rb:210:in `getaddrinfo': getaddrinfo: Name or service not known (SocketError)

sidekiq.rb文件：

Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://redis:6379' }
end
Sidekiq.configure_client do |config|
    config.redis = { url: 'redis://redis:6379'}
end

RadioWorker.perform_async
TestWorker.perform_async
JazzWorker.perform_async

更新：修复了redis错误现在面临的问题与停靠POSTGRES 当应用程序在localhost:3000上运行时，我收到以下错误消息：

我的docker撰写文件：

Dockerfile用于构建映像，而不是运行守护进程。docker构建的结果是静态的（docker图像）。我建议您直接从docker-compose.yml运行redis

redis:
  image: redis

radiofm:
  (...)
  depends_on: redis
  (...)

PostgreSQL也是如此。如果您确实需要在容器启动时设置映像以运行守护进程，那么应该使用脚本来调优CMD

此外，您只能使用CMD一次。

您能发布完整的docker compose.yml吗？redis是否在同一docker compose中？@whites11是的，我一定已经发布了服务和版本，没有其他内容：版本：“3.0”服务：@Robert我在docker compose文件中没有单独的redis映像我通过docker文件开发在第47行安装它运行apt get install-y redis server运行redis server--daemonize yesOk如果我这样尝试的话它是以你为例的，但我似乎无法建立联系。查看更新的信息：）将my database.yml中的host:localhost更改为host:postgres，现在我得到的数据库“development\u db”不存在
