AWS RDS integration with docker-compose Passbolt

Hello,
I’m trying to integrate Passbolt CE that is hosted on an AWS EC2 instance via docker-compose with AWS RDS Postgresql database but for some reason I’m getting an error “There are some issues with the database configuration”. Please Help.

Share your docker compose file belongs to db connectivity?

Did you create the “passbolt” database user and passbolt user in this external database?

Did you follow the following? : https://raw.githubusercontent.com/passbolt/passbolt_docker/master/docker-compose/docker-compose-ce-postgresql.yaml

as @jeewan1981 please share your compose file to see if we can spot an issue

Cheers,
Max
