# Deploying Balinyaar

A first, shareable deployment of the whole stack under **balinyaar.ir**, in Docker, behind an existing
Caddy reverse proxy that terminates TLS.

| Host | Serves | Container |
| --- | --- | --- |
| `balinyaar.ir`, `www.balinyaar.ir` | Next.js web client | `balinyaar-web:3000` |
| `api.balinyaar.ir` | ASP.NET Core API | `balinyaar-api:8080` |
| *(internal only)* | Telegram OTP relay | `balinyaar-otp-relay:5010` |

The **database is not containerised** — it is the remote SQL Server already configured in
[server/src/API/Baya.Web.Api/appsettings.Development.json](server/src/API/Baya.Web.Api/appsettings.Development.json).
Nothing needs to be provisioned for it; the API just needs network reach to `87.107.152.16:1433`.

---

## Configuration model

**There is no `dotnet user-secrets` any more.** The `<UserSecretsId>` was removed from
`Baya.Web.Api.csproj`, so the API no longer reads that store at all — a stale `secrets.json` on a dev
machine is now inert and can be deleted. Every value lives in a file in the repo:

| What | Where |
| --- | --- |
| API config + secrets (DB, JWE keys, field-encryption keys, Telegram key, CORS, trusted proxies) | `server/src/API/Baya.Web.Api/appsettings.Development.json` |
| The two values that differ between a laptop and the container network | `docker-compose.yml` → `api.environment` |
| Client build-time config (API URL, site origin) | `client/.env.production` |
| Telegram relay config (bot token, chat ids, API key, proxy) | `docker-compose.yml` → `otp-relay.environment` |

The API runs as **`ASPNETCORE_ENVIRONMENT=Development`**, so `appsettings.Development.json` is the file
that actually loads. An `appsettings.Production.json` would be ignored — put changes in the Development
file, or change the environment name first.

The relay's shared secret appears twice and the two must match: `Seams:Sms:Telegram:ApiKey` in the
appsettings file and `API_KEY` in the compose file. It was rotated away from the value in
`telegram-otp-bot/.env.example`, which is published in git and in that project's README —
`TelegramSmsSender` now refuses to authenticate with it. **If you run the relay locally**, copy the
appsettings value into your own `telegram-otp-bot/.env`.

> ⚠️ **`Seams:FieldEncryption:Key` and `:HashKey` must never change.** Every encrypted column in that
> database — phone numbers, addresses, IBANs, clinical notes — was written with those exact values, and
> `users.PhoneHash`, which every login looks up, is derived from `HashKey`. Rotating either makes the
> existing data unreadable and locks every account out. The JWE keys (`IdentitySettings:SecretKey` /
> `Encryptkey`) are safe to rotate; doing so only signs everyone out.

## What running as Development means

This was a deliberate choice so the demo and lifecycle seeders populate the shared database and the
screens aren't empty. It has real consequences, all of which are fine for a pre-launch demo among
people you trust, and none of which are acceptable once strangers can reach the site:

- **The developer exception page is public.** Any unhandled 500 on `api.balinyaar.ir` returns a stack
  trace and configuration detail to the caller.
- **`GET /api/v1/dev/last_otp/{phone}` is live.** Anyone who knows a registered phone number can read
  its login code and sign in as that user. This is the single biggest exposure.
- **Swagger is served** at `api.balinyaar.ir/swagger`.
- **The seeders re-run on every container boot** (idempotent, so this is safe — they no-op on data that
  already exists) and **migrations auto-apply on boot** rather than as a separate step.
- **gRPC reflection is enabled**, and the demo `bookings/convert` payment-capture simulator is wired.

### Going to Production later

1. Set `ASPNETCORE_ENVIRONMENT: Production` in `docker-compose.yml`.
2. Create `appsettings.Production.json` with the same content as the Development file, but with **real**
   `IdentitySettings:SecretKey` / `Encryptkey` — `StartupSecretsGuard` rejects anything containing
   `not-for-production` outside Development, so the current dev keys will refuse to boot (by design).
   Keep `Seams:FieldEncryption` byte-identical.
3. Run migrations as a one-shot instead of on boot:
   `docker compose run --rm api dotnet Baya.Web.Api.dll migrate`
4. Swap the OTP rail: `Seams:Sms:Provider` → `kavenegar`, with `Seams:Sms:ApiKey`/`Sender` filled in.
   The Telegram relay broadcasts every code to a fixed recipient list, which stops being acceptable the
   moment someone outside that list can request one.

## First deploy

### 1. Confirm the Caddy network exists

The compose file joins `caddy_net` as an **external** network — it does not create it.

```bash
docker network ls | grep caddy_net
```

### 2. Add the Balinyaar block to your Caddyfile

Copy from [deploy/Caddyfile](deploy/Caddyfile) into the Caddyfile your Caddy container already loads:

```caddyfile
balinyaar.ir, www.balinyaar.ir {
	encode zstd gzip
	reverse_proxy balinyaar-web:3000
}

api.balinyaar.ir {
	encode zstd gzip
	reverse_proxy balinyaar-api:8080
}
```

Caddy obtains and renews the certificates for both hostnames itself. Reload it:

```bash
docker exec <caddy-container> caddy reload --config /etc/caddy/Caddyfile
```

### 3. Point DNS at the host

`balinyaar.ir`, `www.balinyaar.ir` and `api.balinyaar.ir` all need an A record on the server's public IP
**before** Caddy can complete the ACME challenge.

### 4. Confirm the proxy container is up

The relay's hop to `api.telegram.org` is filtered in Iran and goes out through the proxy already on
`caddy_net`, configured as `TELEGRAM_PROXY_URL: http://hysteria-client:8081`. If that container has a
different name or port, change it in `docker-compose.yml` — a wrong value fails the relay at boot with a
clear message rather than silently per-OTP.

### 5. Build and start

```bash
docker compose up -d --build
docker compose ps
docker compose logs -f api
```

The API's first boot applies any pending migrations and runs the seeders against the remote database, so
it takes noticeably longer than later ones.

---

## Verifying

```bash
curl https://api.balinyaar.ir/healthz/live      # process is up
curl https://api.balinyaar.ir/healthz/ready     # + database and object storage reachable
curl -I https://balinyaar.ir                    # the public landing page
docker compose logs otp-relay | head            # should print the bot's @username and the proxy label
```

A full login round-trip is the real check: request an OTP from the site and confirm the code arrives in
the Telegram chat. If it doesn't, `docker compose logs otp-relay` names the failing hop — a proxy error
and a Telegram API rejection look different.

---

## Redeploying

```bash
git pull
docker compose up -d --build
```

Rebuild the client whenever a `NEXT_PUBLIC_*` value in `client/.env.production` changes — those are
compiled into the browser bundle, so restarting the container alone changes nothing.

## Known wrinkle: the client lockfile is Windows-generated

`client/package-lock.json` is produced on Windows, where npm filters out wasm32-only optional packages
and therefore never records their transitive dependencies (`@emnapi/core`, `@emnapi/runtime`). On Linux
npm *does* want them, so a bare `npm ci` fails with:

```
npm error `npm ci` can only install packages when your package.json and package-lock.json ... are in sync.
npm error Missing: @emnapi/runtime@1.11.3 from lock file
```

The client Dockerfile works around this by completing the lock inside the image before installing. To fix
it permanently, regenerate the lock **on Linux** once and commit the result:

```bash
cd client
docker run --rm -v "$PWD:/app" -w /app node:24-alpine npm install --package-lock-only --no-audit --no-fund
```

Then drop the `npm install --package-lock-only` line from `client/Dockerfile`, leaving just `npm ci`.

Note `--omit=optional` is **not** a valid shortcut here: Turbopack resolves `@parcel/watcher`'s native
binary through `optionalDependencies`, so omitting them breaks `next build` with
`No prebuild or local build of @parcel/watcher found`.

## Persisted state

Two named volumes survive rebuilds. Uploaded verification documents live in the first one; losing it
means the admin verification queue shows broken documents.

| Volume | Holds |
| --- | --- |
| `api-object-storage` | Uploaded verification documents (local-disk `IObjectStorage` seam) |
| `api-logs` | Serilog JSON file sink |
