I’ve created a 
short video to better explain how to achieve this configuration: https://youtu.be/C2N092D_K98
To make it easier, I will be using a PostgreSQL Docker image that already contains all the necessary configuration for Bonita (available on Github). I have previously created a Docker image with a Bonita application using Bonita 2023.2. I am using docker compose.
Useful links:
Database configuration documentation: Database configuration | Bonita Documentation
Deploying Bonita with Docker: Deploy Bonita Runtime with Docker | Bonita Documentation
Hope this helps.
Cheers!
