从Docker登录

Question

我有一个通过docker运行的rails应用程序。我用Docker-compose调出应用程序（config下面）。整个应用程序涵盖了一个mysql，redis，rails（包括sidekiq workers），nginx（带有react前端）以及一个rsyslog服务器，它将所有日志转发到Loggly

我的问题与日志记录部分相关。基本上所有服务的日志都会被转发，除了来自sidekiq的日志。 当我用bundler exec sidekiq启动sidekiq时，日志会输出到控制台（标准输出），但是当我在rsyslog服务器上输出/ var/log/messages时，我没有看到它们。

我在泊坞窗设置日志时，遵循本教程：

我的想法是认为云在泊坞窗容器到stdout一切都应该被记录到泊坞窗日志机制 - 与我设置这意味着它应该去的syslog服务器...

泊坞窗，撰写文件：

正如评论的解决方案是作为搬运工，撰写文件的CMD的一部分运行包的命令提示由@Robert：

在我撰写文件中的api服务因此成为：

api: 
    image: pt-rails 
    env_file: .env.dev 
    networks: 
     - phototankswarm 
    command: > 
     sh -c ' 
     bundle exec sidekiq -d -L /dev/stdout && bundle exec rails s -p 3000 -b 0.0.0.0 
     ' 
    volumes: 
     - /Users/martinhinge/Pictures/docker/phototank:/media/phototank 
     - ./backend:/usr/src/app 
    ports: 
     - "3000:3000" 
    depends_on: 
     - db 
     - redis 
     - syslog 
    logging: 
     driver: syslog 
     options: 
     syslog-facility: "daemon" 
     tag: "rails" 
     syslog-address: "tcp://localhost:5514"
