  • adding a python script that will connect to Postgresql, create database, schema, and table if not exists
  • plug that database initialization script on the startup of Fastapi api
    • without coupling it too much with the app:

we can modulate the app behavior with an environment variable 'INIT_DB' if we want to disable the Postgresql interactions

also added two simple unit tests to prove that database init code is not triggered during unit tests

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
