multica/docker-compose.selfhost.yml

# Self-hosting Docker Compose — starts PostgreSQL, backend, and frontend.
#
# Usage:
#   cp .env.example .env
#   # Edit .env — change JWT_SECRET at minimum
#   docker compose -f docker-compose.selfhost.yml up -d
#
# Frontend: https://$TASK_DOMAIN (via Caddy reverse proxy)
# Backend:  internal on backend:8080 (health exposed at /health through Caddy)
