Externalizing Grails Datasource configuration

Question

Grails 1.x allows using external configuration files by setting the grails.config.locations directive. Is there a similar approach available for externalizi

Answer 1

The answer above does not really externalize configuration. He is close, but the configuration is still residing in the application. I would use a JVM environment var on startup of the application/server to point to a location outside the application where the external configuration resides. Read out the environment var in the config.groovy file and use it get the external configuration file. Something like this:

def extConfig = System.properties.getProperty('ENVVAR');
grails.config.locations = [ "file:${extConfig}/${appName}-config.groovy"]
