-# The commented out section below is an example of how to define a PostgreSQL

-# start the database before your application. The `db-data` volume persists the
-# database data between container restarts. The `db-password` secret is used
-# to set the database password. You must create `db/password.txt` and add
-# a password of your choosing to it before running `docker-compose up`.
