# TrueNAS deploy — datarhei Core (M2, WebRTC-in-Core)

Host-networked Docker stack that runs the real root Core binary with
the M2 WebRTC egress subsystem wired in. This replaces the M1
`webrtc-poc` stack — WebRTC is now a first-class output alongside
RTMP/SRT/HLS.

## What changed from M1

| M1 (webrtc-poc)                        | M2 (this stack)                              |
| -------------------------------------- | -------------------------------------------- |
| Standalone `cmd/webrtc-poc` binary     | Full Core with restream, HTTP API, storage   |
| One hard-coded stream id               | Every restream process can opt into WebRTC   |
| Single UDP ingest, PT-split forwarding | Two UDP ports per process, per-track         |
| Plain `/whep/:id` on a side port       | `/api/v3/whep/:id` on the JWT-protected API  |
| No auth                                | JWT (same creds as the rest of Core)         |

## Prereqs

- Docker on the TrueNAS host (TrueNAS SCALE includes it)
- LAN or public IP that clients can reach (set in `.env` as `PUBLIC_IP`)
- Admin credentials for Core's API
- FFmpeg is bundled in the image — no host install required

## One-time setup

```
sudo mkdir -p /mnt/NVME/Docker/dragonfork-core
cd /mnt/NVME/Docker/dragonfork-core

# Pull the repo (or sync deploy files) onto the host. The compose
# build `context:` points at the repo root.
git clone https://forgejo.wilddragon.net/zgaetano/datarhei-dragonfork-core.git
cd datarhei-dragonfork-core/deploy/truenas/core

cat > .env <<EOF
PUBLIC_IP=10.0.0.25
CORE_HTTP_PORT=8080
API_AUTH_USERNAME=admin
API_AUTH_PASSWORD=$(openssl rand -base64 24)
API_AUTH_JWT_SECRET=$(openssl rand -base64 48)
LOG_LEVEL=info
EOF

mkdir -p config data
```

## Run

```
docker compose up -d --build
docker compose logs -f
```

You should see Core come up logging all configured listeners, including
a line from the WebRTC component confirming the subsystem is enabled.

## Smoke-test via API

```
# Issue a JWT against the admin creds from .env:
TOKEN=$(curl -s -X POST -H 'Content-Type: application/json' \
  -d '{"username":"admin","password":"<from .env>"}' \
  http://10.0.0.25:8080/api/login | jq -r '.access_token')

# Probe the WHEP endpoint — should 404 for an unknown id.
curl -i -H "Authorization: Bearer $TOKEN" \
  -X POST http://10.0.0.25:8080/api/v3/whep/nope
# → HTTP/1.1 404 Not Found

# Create a process with WebRTC enabled, send RTMP to its input, then
# subscribe the Pion whep-client to /api/v3/whep/<process-id>.
```

## Cutting over from the M1 PoC

The M1 `webrtc-poc` stack is independent; it binds its own ports. You
can run both side-by-side during the cutover:

```
# Stop the M1 stack when you're ready to retire it:
cd /mnt/NVME/Docker/dragonfork-webrtc-poc
docker compose down
```

## Teardown

```
docker compose down
```

## Security notes

- The WHEP endpoint is mounted under `/api/v3`, which is JWT-protected.
  That's the M2 posture — WHEP clients (browsers) need a token. M3
  adds per-process signed-URL tokens so embeds don't require admin
  credentials.
- The binary runs as root inside the container; if you need an unpriv
  user, mount volumes owned by a fixed UID and add a `user:` directive.
  This matches how the upstream datarhei/core image ships.
- Put Caddy or nginx in front for TLS. The media itself is
  DTLS-SRTP-encrypted regardless.
