# prestart.sh — Container entrypoint for CRM System
|
|
#
|
|
# Responsibilities:
|
|
# 1. Run Alembic DB migrations (alembic upgrade head).
|
|
# 2. Start uvicorn as PID 1 (so signals like SIGTERM are forwarded correctly).
|
|
#
|
|
# Notes:
|
|
# - `set -e` ensures the container crashes loudly if migrations fail,
|
|
# rather than starting a broken app on an inconsistent schema.
|
|
# - `exec uvicorn ...` replaces the shell process with uvicorn, so uvicorn
|
|
# becomes PID 1 and receives Docker's SIGTERM directly for graceful shutdown.
|
|
# - `--workers 1` is intentional for v1: SQLite (dev) is single-threaded,
|
|
# and asyncpg (prod) scales fine with one worker + an async connection pool.
