The property sources that are added to you application by the bootstrap context are often “remote” (e.g. from a Config Server), and by default they cannot be overridden locally, except on the command line.

If you want to allow your applications to override the remote properties with their own system properties or config files, the remote property source has to grant it permission by setting

It doesn’t work to set this locally. It must be set as property in the remote property source (i.e. {application}-{profile}.properties file on a Git repository).

Once that flag is set there are some finer grained settings to control the location of the remote properties in relation to System properties and the application’s local configuration:

  • to override with any local property source
  • if only System properties and env vars should override the remote settings, but not the local config files
