How to run application as service and managing logging in production

• Install foreman gem to manage processes

  Procfile

  web: rails server

• Type following command from inside the project directory:-

  $ sudo foreman export --app app_name --user prashant upstart /etc/init

  $ ls /etc/init/app_name*

  $ ls /var/log/app_name/

In this way out app is on par with a core system service. We don’t have to dabble with PID files, system handles that. The OS will automatically reboot service if it crashes, rotate logs.

rails_12factor gem

1. This gem redirects log in production to stdout, from there we can manage the log through OS or use any log aggregation service like papertrail gem.

2. It enables rails app server to serve static assets which is actually giving more control to rails app server. This is usually managed through reverse proxy server like Ngnix/Apache.

It basically enables this flag config.serve_static_assets = true
