      Is the database always created/populated when container is built
or it is stored in a separate volume that is then connected at
runtime?

      I take that means a DB rebuild relies on these SQL scripts to
populate it. Are said scripts run from a Dockerfile or a script (like
entrypoint)? If I were in your shoes, I would disable the running of
said scripts, then build and run DB container, and then run each SQL
script manually to find out where it goes boink (and figure out if it
is a docker or a script issue).
