I would suggest you to use spring profiles (https://docs.spring.io/spring-boot/docs/1.2.0.M1/reference/html/boot-features-profiles.html) which allowes you to create different property / yaml etc. files for storing your properties like follows:

application-prod.properties
application-extra.properties
application-dev.properties
application-local.properties

Then you can use for example a command line param to indicate which profiles you want to use:

java -jar YOUR.jar --spring.profiles.active=prod,extra

You can use different profiles at the same time and you can also provide a standard set of properties in your application.yaml, so you only have to override the properties that change in your profile based configuration.
