+# Dokploy Deployment
+
+## Assumptions
+
+- **Frontend**: React Vite SPA built with Bun, served by nginx. Single public entry point.
+- **Backend**: FastAPI, internal only. No Traefik labels, no public ports.
+- **Routing**: nginx proxies `/api` to backend. Traefik routes all traffic to frontend (port 80).
+- **Domain**: Replace `your-domain.com` in Traefik labels with your actual domain.
+
+## Build & Run Locally
+
+```bash
+# Create network (Dokploy provides this)
+docker network create dokploy-network 2>/dev/null || true
+
+# Build and run
+docker compose up --build
+```
+
+Frontend will be on port 80 (or the mapped port). Backend is internal.
+
+## Dokploy Setup
+
+1. Create `dokploy-network` if not exists:
+   ```bash
+   docker network create dokploy-network
+   ```
+
+2. Deploy via Dokploy UI: add project, use this `docker-compose.yml`.
+
+3. Set environment variables in Dokploy:
+   - `CORS_ORIGINS`: Comma-separated allowed origins (e.g. `https://your-domain.com`)
+
+4. Update Traefik labels in `docker-compose.yml`:
+   - Replace `your-domain.com` with your domain
+   - Ensure `certResolver=letsencrypt` matches your Traefik config
+
+## Port Rules
+
+- **Frontend**: Exposes port 80 internally. Traefik routes to it.
+- **Backend**: No ports exposed. Communicates via `dokploy-network`.
+
+## Service Communication
+
+- Frontend (nginx) proxies `/api` to `http://backend:8000`
+- Backend is reachable only from within the Docker network
