# 131 — `teddycloud`

Open-source replacement server for Toniebox smart audio devices (Tonieboxes). Serves device content and API on port 443 and exposes a management web UI at `teddy.hubris.network`.

## At a glance

- **Hostname:** `teddycloud`
- **IP:** `192.168.8.243` (DHCP reservation; MAC `bc:24:11:11:7a:df`)
- **Privilege:** privileged
- **Resources:** 1 core / 1 GiB RAM / 16 GiB rootfs (Debian 12)
- **Mounts:** `/mnt/library` (`mp0`) — TeddyCloud content at `/mnt/library/cloud/leon`
- **Public hostname:** none (LAN-only)

## Role

Replaces the Boxine cloud (`prod.de.bb-online.com`) as the backend for Leon's Toniebox. Tonieboxes connect on port 443 using a custom CA cert issued by TeddyCloud. Content (Tonies) is stored on the NAS at `/mnt/library/cloud/leon` and is accessible from the management UI.

## Service / port map

| Service | Listen | Notes |
|---------|--------|-------|
| TeddyCloud device API | `0.0.0.0:443` | HTTPS, TeddyCloud self-signed CA, Toniebox connects here |
| TeddyCloud HTTP | `0.0.0.0:80` | Redirects to 443 |
| TeddyCloud web UI | `0.0.0.0:8443` | HTTPS management UI — fronted by Caddy at `teddy.hubris.network` (backend uses `tls_insecure_skip_verify` for self-signed cert on LAN hop) |

## Docker Compose

`/opt/teddycloud/docker-compose.yml`:

```yaml
services:
  teddycloud:
    image: ghcr.io/toniebox-reverse-engineering/teddycloud:latest
    ports:
      - "80:80"
      - "443:443"
      - "8443:8443"
    volumes:
      - certs:/teddycloud/certs
      - config:/teddycloud/config
      - /mnt/library/cloud/leon:/teddycloud/content
      - /mnt/library/cloud/leon:/teddycloud/library
    restart: unless-stopped

volumes:
  certs:
  config:
```

`certs` and `config` are Docker named volumes (runtime state). `content` and `library` are bind-mounted from `/mnt/library/cloud/leon` so audio content persists across container rebuilds and is browsable from the host.

## Storage / config paths

- `/opt/teddycloud/docker-compose.yml` — compose file
- Docker volume `teddycloud_certs` — TeddyCloud CA + server certs (generated on first boot)
- Docker volume `teddycloud_config` — TeddyCloud config
- `/mnt/library/cloud/leon/` — Tonie content + library (NAS bind mount)

## Networking

Two separate traffic paths — different IPs, no port 443 conflict:

**Management UI (browser):**
```
teddy.hubris.network → Technitium → 192.168.8.175 (Caddy) → 192.168.8.243:8443
```

**Toniebox device traffic:**
```
prod.de.bb-online.com → Technitium override → 192.168.8.243:443 (TeddyCloud direct)
```

Caddy terminates TLS for the management UI (IONOS DNS-01 wildcard cert). TeddyCloud terminates TLS for device traffic with its own self-signed CA — the Toniebox must have this CA installed.

### DNS overrides in Technitium

| Record | Type | Value | Purpose |
|--------|------|-------|---------|
| `teddy.hubris.network` | A | `192.168.8.175` | Management UI → Caddy (standard pattern) |
| `prod.de.bb-online.com` | A | `192.168.8.243` | Toniebox device traffic → TeddyCloud direct |

The `prod.de.bb-online.com` override is Technitium-only — it intercepts Toniebox DNS locally without touching public DNS. The `dns-sync.py` cron on LXC 107 skips non-`hubris.network` records, so it stays local.

## Config notes

- `core.boxCertAuth=false` — client cert validation disabled. The box connects without presenting its unique client cert. Set in `/var/lib/docker/volumes/teddycloud_config/_data/config.ini` (TeddyCloud hot-reloads on change).
- If you ever want per-box auth, flip to `true` and supply `certs/client/ca.der`, `client.der`, `private.der` extracted from the box flash.

## Toniebox onboarding — ESP32 SD card method

Leon's box is ESP32 generation. No hardware mod required.

1. Download the TeddyCloud CA cert from the web UI: **Security → CA Certificate → Download CA** (`ca.der`).
2. Power off the Toniebox, remove the SD card.
3. On the SD card, create folder `cert/` at the root.
4. Copy the downloaded `ca.der` into `cert/ca.der` on the SD card.
5. Reinsert SD card, power on the box.
6. The box patches itself to trust TeddyCloud's CA, then resolves `prod.de.bb-online.com` via Technitium's override (`192.168.8.243`) and connects on port 443.
