# HR-ATS-Portal — single Compose file for local and production.
#
#   docker compose up -d --build
#
# Root `.env` only sets COMPOSE_ENV_FILES=./backend/.env so ${FRONTEND_PORT},
# ${BACKEND_PORT}, ${UVICORN_WORKERS}, … interpolate from backend/.env.
# Secrets and app config live solely in backend/.env (loaded into containers
# via env_file as well).
#
# Local (PROD_ENV=false, DB_HOST=localhost in backend/.env):
#   Containers reach host Postgres via host.docker.internal (db_setup rewrite
#   when IN_DOCKER=1). Frontend :5173, API :8000 by default.
#
# Prod (PROD_ENV=true, DB_* = RDS in backend/.env — edit manually):
#   Same command. No host rewrite; SSL require when DB_SSLMODE is blank.
#
# Optional Compose Postgres:
#   docker compose --profile postgres up -d postgres
#
# Optional live-reload / bind mounts:
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d --build
#
# See DOCKER.md for env checklist and verification.
