The Config Server is a ruby application based on the Sinatra simple web framework. Sinatra is an extension to the ruby rack framework. The RACK_ENV variable controls which environment rack thinks it is running in. This essentially controls where the instance configuration data is stored by the Config Server (see Instance configuration storage on the Audrey page). The default value is "production".
