docker-compose.prod.yml

# Production overlay for a free VM (e.g. Oracle Cloud Always Free) that
# hosts the BACKEND ONLY -- the frontend stays on Vercel and reaches this
# over the network via NEXT_PUBLIC_API_URL.
#
# Usage: docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build db api caddy
# (deliberately omits `web`: the Next.js container has no purpose on this
# VM when Vercel already serves the frontend)
#
# Puts Caddy in front as the only publicly-exposed service (80/443) and
# stops publishing host ports for db/api directly, since on a real VM
# (unlike local dev) those ports are reachable from the internet, not just
# localhost.
