Depending on the version of Ruby and transport you need you can use different Helcon Zoo appliction engines as a 'scriptProcessor' value. Following engines are available: ruby.1.8.rack, ruby.1.9.rack, ruby.1.9.http, ruby.2.0.rack, ruby.2.0.http.
Environment variables:
-
APP_WORKER— path to the main application script. Note, Helicon Zoo automatically detects Rails and picks up “config.ru” file. -
DEPLOY_FILE— optional path to a ruby script which is run before application launch and every time IIS application pool recycles. The script usually contains deployment instructions to satisfy application dependencies and database migrations. -
DEPLOY_LOG— optional path to a text file containing the output of the deploy script. It’s recommended to set this variable if you use deploy script. -
RACK_ENV— specifies application running mode. Default value is “production”. This variable is duplicated intoRAILS_ENVvariable.
