從Docker登錄

Question

我有一個通過docker運行的rails應用程序。我用Docker-compose調出應用程序（config下面）。整個應用程序涵蓋了一個mysql，redis，rails（包括sidekiq workers），nginx（帶有react前端）以及一個rsyslog服務器，它將所有日誌轉發到Loggly

我的問題與日誌記錄部分相關。基本上所有服務的日誌都會被轉發，除了來自sidekiq的日誌。 當我用bundler exec sidekiq啓動sidekiq時，日誌會輸出到控制檯（標準輸出），但是當我在rsyslog服務器上輸出/ var/log/messages時，我沒有看到它們。

我在泊塢窗設置日誌時，遵循本教程：

我的想法是認爲雲在泊塢窗容器到stdout一切都應該被記錄到泊塢窗日誌機制 - 與我設置這意味着它應該去的syslog服務器...

泊塢窗，撰寫文件：

正如評論的解決方案是作爲搬運工，撰寫文件的CMD的一部分運行包的命令提示由@Robert：

在我撰寫文件中的api服務因此成爲：

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"
