# DigitalOcean Deployment Spec
|
|
|
|
PodMan backend (Hermes) runs on DigitalOcean. Frontend is served as a static site. Both are deployed from the same monorepo.

## Dockerfile (backend)
|
|
|
|
Located at `infra/Dockerfile`. Already scaffolded. Ensure it:
|
|
|
|
1. Uses `node:20-slim`
|
|
2. Installs `pnpm`
|
|
3. Copies workspace root + backend package
|
|
4. Runs `pnpm install --frozen-lockfile`
|
|
5. Runs `pnpm --filter backend build`
|
|
6. `CMD ["node", "backend/dist/index.js"]`
|
|

## Deploy checklist
|
|
|
|
- [ ] MongoDB Atlas IP allowlist: add DigitalOcean outbound IPs (or allow all: `0.0.0.0/0` for hackathon)
|
|
- [ ] LiveKit Cloud: confirm `LIVEKIT_URL` points to your LiveKit Cloud project
|
|
- [ ] Gemini API key has quota for `gemini-2.0-flash` + `gemini-live-2.5-flash`
|
|
- [ ] `VITE_BACKEND_URL` set to the deployed Hermes URL (not localhost)
|
|
- [ ] Test `GET /health` returns `{ ok: true }` after deploy
|

|
## Fallback plan (if App Platform deploy fails on stage)
|
|
|
|
Run Hermes locally:
|
|
|
|
```bash
|
|
cd backend && pnpm dev
|
|
```
|
|
|
|
Frontend already points to `http://localhost:8787` by default via `VITE_BACKEND_URL` fallback. Demo works fully local — no DigitalOcean dependency for the live demo itself.
