# =============================================================================
# docker-compose.yml — production stack consumed by deploy.sh
# =============================================================================
#
# Complete Docker stack for production deployment:
#   - Next.js frontend (Node.js standalone server)
#   - PostgREST API (optional, for direct PostgreSQL access)
#
# Postgres itself runs on the host (the deploy workflow applies migrations
# via `psql -h 127.0.0.1`). Next.js can also run under PM2 on the host —
# this compose file provides a Docker alternative for the frontend.
#
# The host-side ports are written by the deploy workflow into $APP_DIR/.env.
# We interpolate from there with ${VAR:-default} so a manual
# `docker compose up` without the deploy script still works.
