"""Startup script for the Alpine Bits Python Server API.
|
|
|
|
This script:
|
|
1. Runs database migrations using Alembic
|
|
2. Starts the FastAPI application with uvicorn
|
|
|
|
Database migrations are run BEFORE starting the server to ensure the schema
|
|
is up to date. This approach works well with multiple workers since migrations
|
|
complete before any worker starts processing requests.
