Hello.

Here’s the solution: [Spring Boot integration with a differnet database - #2 by fiki574](https://forum.flowable.org/t/spring-boot-integration-with-a-differnet-database/5993/2)

EDIT:  
My bad, you don’t have a standalone Spring Boot application, you would rather override the properties for the default database connection of the Flowable instance.

I use Docker, and here’s how I did it there:  
SPRING\_DATASOURCE\_DRIVER-CLASS-NAME: org.postgresql.Driver  
SPRING\_DATASOURCE\_URL: jdbc:postgresql://flowable-postgres:5432/flowable  
SPRING\_DATASOURCE\_USERNAME: flowable  
SPRING\_DATASOURCE\_PASSWORD: flowable

So the properties you’re overriding are correct, however it might be at a “wrong location” in the file system.
