Deployment

This project was generated with the following deployment-related flags:

• ✅ Docker / docker-compose.yml
• ❌ No Kubernetes manifests
• CI: github
• Reverse proxy: Nginx

---

Docker Compose (single host)

For staging or small production:

# 1. Configure
cp backend/.env.example backend/.env
# Edit backend/.env with production values (see ENV_VARS.md)

# 2. Build + start
docker compose up -d --build

# 3. Apply migrations
docker compose exec app uv run alembic upgrade head


# 4. Verify
curl http://localhost:8000/api/v1/health
# Frontend: http://localhost:3000

Reverse proxy

Nginx config in nginx/ proxies / → frontend, /api → backend, /ws → backend WebSocket. Update server_name and TLS cert paths in nginx/conf.d/app.conf.

Platform-specific quickstarts

Fly.io

fly launch --name agent_delta-backend --region waw
fly postgres create --name agent_delta-db
fly postgres attach agent_delta-db
# Redis: use Upstash (`fly redis create`) or Fly's Tigris
fly secrets set $(cat backend/.env | grep -v '^#' | xargs)
fly deploy

Railway

1. Connect repo, pick Dockerfile-based deploy.
2. Add env vars from backend/.env to Railway service.
3. Provision PostgreSQL plugin → DATABASE_URL auto-injected.
4. Provision Redis plugin → REDIS_URL auto-injected.
5. Deploy.

Render

1. Create Web Service → docker, point at backend/Dockerfile.
2. Create Static Site for frontend (build cmd: bun install && bun run build, output dir: .next).
3. Create PostgreSQL → copy DATABASE_URL.
4. Add env vars; deploy.

Vercel (frontend only)

The frontend is a Next.js app — works on Vercel out of the box.

cd frontend
vercel

Set BACKEND_URL and NEXT_PUBLIC_API_URL env vars in Vercel dashboard pointing to your backend host.

Environment validation in production

Before promoting to prod, run:

docker compose exec app uv run python -c "from app.core.config import settings; print('OK')"

Catches missing required env vars early. See ENV_VARS.md for the full list.

Post-deploy checks

• /api/v1/health returns {"status": "ok"}
• alembic current matches expected revision
• Frontend renders, login flow works end-to-end
• Logs flowing to your aggregator + Logfire receiving traces
• Reverse proxy enforces HTTPS

Rollback

• Schema: alembic downgrade -1 rolls back one migration. Test on staging first.
• Code: redeploy previous image tag. Pin tags (v1.2.3), never deploy latest to prod.
• Data: restore from your most recent backup; verify alembic current matches the data version.
