How to manage application.conf in several environments with play 2.0?

Question

With Play 1.2, I can prefix the configuration keys with the framework ID or application mode as follows:

# Production configuration
%prod.http.port=80
%prod.

If you want to be indepentent from restrited scala run modes you can use JVM properties. Put modified @coffesnake example to ./app/Global.scala :

import java.io.File

import play.api._
import com.typesafe.config.ConfigFactory

object Global extends GlobalSettings {
  override def onLoadConfig(config: Configuration, path: File, classloader: ClassLoader, mode: Mode.Mode): Configuration = {
    val environment = System.getProperty("environment")
    val environmentSpecificConfig = config ++ Configuration(ConfigFactory.load(s"application.${environment}.conf"))
    super.onLoadConfig(environmentSpecificConfig, path, classloader, mode)
  }
}

Next run play play

and start app with environment param run -Denvironment=prod-server1

Don't join both command, it doesn't work then

Global configuration will be overrided with environment specific properties from file:

./conf/application.prod-server1.conf

EDIT:

From time perspective I saw this workaround is unnecessary. It is better to use Play build-in config loading mechanism -Dconfig.file=/etc/play-application/foo-production.conf
