multica/docker-compose.selfhost.yml

# Self-hosting Docker Compose — starts PostgreSQL, backend, and frontend.
#
# Services bind to 127.0.0.1 only. For cross-machine or public access, front
# them with a reverse proxy (Caddy / nginx / Cloudflare Tunnel) that terminates
# TLS and forwards to 127.0.0.1:8080 (backend) and 127.0.0.1:3000 (frontend).
# Do NOT change these bindings to 0.0.0.0 — Docker bypasses host firewalls
# (UFW/iptables) by default, so the raw ports would be exposed to the internet
# with the default JWT_SECRET and Postgres credentials. See:
#   apps/docs/content/docs/self-host-quickstart.mdx
#
# Usage:
#   cp .env.example .env
#   # Edit .env — change JWT_SECRET at minimum
#   docker compose -f docker-compose.selfhost.yml up -d
#
# Frontend: http://localhost:${FRONTEND_PORT:-3000}
# Backend:  http://localhost:${BACKEND_PORT:-${API_PORT:-${SERVER_PORT:-${PORT:-8080}}}}
