+# 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:** `192.168.8.214` (DHCP reservation)
+- **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 | `0.0.0.0:8080` | HTTP management UI — fronted by Caddy at `teddy.hubris.network` |
+| TeddyCloud web UI (HTTPS) | `0.0.0.0:8443` | HTTPS management UI (direct, not Caddy-fronted) |
+
+## Docker Compose
+
+`/opt/teddycloud/docker-compose.yml`:
+
+```yaml
+services:
+  teddycloud:
+    image: ghcr.io/toniebox-reverse-engineering/teddycloud:latest
+    ports:
+      - "80:80"
+      - "443:443"
+      - "8080:8080"
+      - "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) → 192.168.8.214:8080
+```
+
+**Toniebox device traffic:**
+```
+prod.de.bb-online.com → Technitium override → 192.168.8.214:443 (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 | `192.168.8.214` | 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.
+
+## Toniebox onboarding
+
+To point a Toniebox at TeddyCloud:
+
+1. Download the TeddyCloud CA cert from the web UI: **Settings → TeddyCloud CA**.
+2. Flash it to the Toniebox via SD card or firmware patch (procedure varies by hardware generation — see [upstream wiki](https://github.com/toniebox-reverse-engineering/teddycloud/wiki)).
+3. The box resolves `prod.de.bb-online.com` to Technitium's override (`192.168.8.214`) and connects on port 443 using TeddyCloud's CA.

+## Changelog
+
+### 2026-06-29 — provisioned
+
+LXC 131 created (Debian 12, privileged, nesting=1). Docker installed. TeddyCloud running via Docker Compose at `/opt/teddycloud/`. Content bind-mounted from `/mnt/library/cloud/leon`. Caddy block added at `teddy.hubris.network → :8080`. Technitium A records: `teddy.hubris.network → 192.168.8.175` (Caddy), `prod.de.bb-online.com → 192.168.8.214` (device traffic direct).

+### 2026-06-29 — `teddy.hubris.network` added; `prod.de.bb-online.com` override added
+TeddyCloud (LXC 131) provisioned. `teddy.hubris.network → 192.168.8.175` (Caddy → TeddyCloud web UI at :8080). Non-hubris override `prod.de.bb-online.com → 192.168.8.214` routes Toniebox device HTTPS traffic directly to TeddyCloud port 443 — this bypasses Caddy and is Technitium-only (dns-sync cron does not replicate non-hubris.network records to the NetBird managed zone).

 ### 2026-06-28 — `plato.hubris.network` removed
 Plato (LXC 126) decommissioned. Technitium entry deleted; dns-sync cron reaped the NetBird managed zone record.
