# healthee — production compose stack (used by deployment.sh on the VPS).
#
# Two services:
#   db   — TimescaleDB (Postgres + timescaledb extension), data on a named volume
#   api  — FastAPI app behind host-nginx, bound to 127.0.0.1 only
#
# Run via deployment.sh, or directly:
#   docker compose -f docker-compose.prod.yml up -d --build
#   docker compose -f docker-compose.prod.yml exec api healthee init-db
#
# Env values come from .env in the project root.
# (The plain docker-compose.yml stays as the LOCAL DEV DB-only stack.)
