Dockerfile

# syntax=docker/dockerfile:1
# Minitor production image — one artifact that Railway, Render, Fly, and any
# Docker host can build straight from source. Pairs with a Postgres database
# (docker-compose bundles one; Railway/Render provide a managed one).

# Build in hosted mode. NEXT_PUBLIC_MINITOR_HOSTED is inlined into the client
# bundle here (build-time only), so the Settings dialog renders read-only.
# DATABASE_URL=memory:// guarantees the build never touches disk or a real DB
# (the app instantiates its DB client at import time).
