Converting Grails Config.groovy, Gradle.build and BuildConfig.groovy to Yaml files

Question

Currently working on a Grails 3 application, that uses an implementation of Redis/Redisson plugins for 2nd level caching(and perhaps some explicit implementation in the near future). With the guides however, I am having trouble understanding how to configure the application with Yaml files, as opposed to the typical config files used in Grails 2 applications I've worked on recently.

The below screenshots are the instructions provided for how to configure the redis implementation, given what appears to be a Spring Java application.

My question is what the counterpart of these files would be if they were for a Grails 3 application, and were Yaml and DOTproperties files.
