Environment

Docker on Linux

Steps to reproduce

Install and run, Only in-memory works. Dont see any tables in postgres, No error messages on docker compose up

Expected behavior

Data should persist to postgres

Version

latest

Severity

Critical

Additional Information

There has got to be better documentation or full examples to use a database like postgres

Start with the docker-compose service configuration and the listed Postgres environment variables, including DATABASE_URL, MEMU_DATABASE_URL, and the depends_on entry. Reproduce the deployment on Docker/Linux, inspect the service logs and database state, and confirm that the application creates and persists tables in Postgres rather than using in-memory storage.
