问题
According to the SpringBoot documentation, the order of configuration is as:
Profile-specific application properties outside of your packaged jar (application-{profile}.properties and YAML variants)
Profile-specific application properties packaged inside your jar (application-{profile}.properties and YAML variants)
Application properties outside of your packaged jar (application.properties and YAML variants).
Application properties packaged inside your jar (application.properties and YAML variants).
On my project I have a profile called "prod" and the following files:
- application.yml (inside the jar)
- application-prod.yml (inside the jar)
And I also want to override some of the properties using an external file. Since according to the docs, an external application.yml will be overridden by the internal application-prod.yml, I need to make sure that the external file is considered as a profile specific config file.
I have tried to use:
-Dspring.config.location=<my path>/application-prod.yml
and I have also tried:
-Dspring.config.location=file:<my path>/application-prod.yml
In all cases I get the value from the internal application-prod.yml
If I totally remove the internal config file then I get the value from the external (so I know that the config picks up the file).
I understand that this external file is considered as the equivalent to the generic application.yml and not a profile specific.
How can I configure it to be considered as a profile specific external config?

Found the answer:
You need to use a Directory externally to set the profile specific configuration files, not using the file directly and it needs to end in /. So it has to be:
-Dspring.profiles.active=prod
-Dspring.config.location=/<some-path>/config/ (any path that ends in /)
and in there have a :
application-prod.yml
