Keycloak embedded in spring boot official docs

Getting advice
1

Hi!

I am looking for official documentation of Keycloak embedded in a spring-boot application.

I’m reading these currently:

  1. https://www.baeldung.com/keycloak-embedded-in-spring-boot-app
  2. https://github.com/thomasdarimont/embedded-spring-boot-keycloak-server

However, I think I won’t be able to get the complete information that I need here.
e.g.

  1. Can I configure it to make KC use a different datasource? - from these they are using spring.datasource
  2. Clustering with embedded KC
  3. And more questions…

Could someone please lead me to some official documentation about embedded KC in spring-boot?

Thank you!
