trmnl (128): provisioned — container page, inventory, ingress

LXC 128 trmnl hosts the TRMNL plugins middleware (dtoro/terminalito), polled by
TRMNL cloud. trmnl-plugins.service on :9851; Caddy block + LE cert; VPS traefik
router trmnl-public + cert mirror. Public path pending VPS<->home netbird route
recovery (was "No networks available" at provision time, artifacto/blog 504 too).
LAN Technitium record + SOPS enrollment + Google/MVG creds pending. Plan -> In Progress.

+# 128 — `trmnl`
+
+Self-hosted middleware for TRMNL e-ink plugins. TRMNL cloud polls it; it fetches/shapes live data into JSON the plugin's Liquid template renders.
+
+## At a glance
+- **Hostname:** `trmnl`
+- **IP:** `192.168.8.211`
+- **Privilege:** unprivileged
+- **Resources:** 1 core / 768 MiB RAM / 8 GiB rootfs (Debian 13)
+- **Mounts:** none
+- **Public hostname:** `trmnl.hubris.network` (via [VPS ingress](../infrastructure/ingress.md))
+
+## Role
+Runs one FastAPI aggregator (`server.app:app`, port 9851) that mounts a router per plugin from the `dtoro/terminalito` repo. First consumer: `munich-home` (`/munich-home/dashboard`) — weather (Open-Meteo), MVG transit, Google Calendar, plus server-side Kita/quote logic. Talks out to the public internet for those APIs; TRMNL cloud polls it inbound every 15 min. Bearer-token gated (`TRMNL_POLL_TOKEN`); `/health` is open.
+
+## Service / port map
+| Service | Listen | Notes |
+|---------|--------|-------|
+| `trmnl-plugins` | `0.0.0.0:9851` | uvicorn aggregator; `EnvironmentFile=/etc/trmnl-plugins/env` |
+
+## Storage / config paths
+- `/opt/terminalito` — git checkout (origin = internal gitea `http://192.168.8.121:3000/dtoro/terminalito.git`)
+- `/opt/terminalito/server/.venv` — venv
+- `/etc/trmnl-plugins/env` — `TRMNL_POLL_TOKEN` (+ Google/MVG creds once enrolled)
+- `/etc/systemd/system/trmnl-plugins.service`
+
+## Auto-deploy
+Not yet wired. Manual deploy: `pct exec 128 -- /opt/terminalito/server/deploy/deploy.sh`. When wired it follows [auto-deploy](../infrastructure/auto-deploy.md) Shape B (`/opt/terminalito-deploy/`, gitea webhook on `dtoro/terminalito`, add `192.168.8.211` to gitea `ALLOWED_HOST_LIST`).
+
+## Secrets
+Not yet SOPS-enrolled. The poll token is set directly in `/etc/trmnl-plugins/env`. Google Calendar + MVG creds are pending: enroll via `homelab client add trmnl` + bootstrap, add `secrets/trmnl-oauth.yaml`, then `server/deploy/render-env.sh` builds the env from `homelab secret trmnl-oauth`. Until then calendar/transit cards degrade to empty; weather works.

+## Changelog
+### 2026-06-24 — provisioned
+LXC 128 created (Debian 13, unprivileged, `192.168.8.211`). Deployed `trmnl-plugins.service` on :9851 from `dtoro/terminalito`. Caddy block added (`dtoro/caddy-conf`) + LE cert via IONOS DNS-01; verified `/health` 200 and `/munich-home/dashboard` (live weather) through Caddy. Cert mirrored to VPS (`trmnl.fullchain.crt`/`trmnl.privkey.key`) + traefik router `trmnl-public` → `192.168.8.211:9851` added to `/opt/traefik-dynamic.yaml`. **Public path pending**: VPS↔home netbird route was down at provision time (`No networks available`, 3/6 peers — artifacto/blog also 504); resolves when the mesh route recovers. **LAN pending**: Technitium A record not yet added. Not SOPS-enrolled; Google/MVG creds pending.

+### 2026-06-24 — `trmnl.hubris.network` exposed
+TRMNL plugins middleware on [trmnl (128)](../containers/128-trmnl.md). File-provider router `trmnl-public` → `192.168.8.211:9851`, `trmnl-ratelimit` (20 rps / 40 burst), cert mirrored as `trmnl.fullchain.crt`/`trmnl.privkey.key`. Note: provisioned while the VPS↔home netbird route was down (`No networks available`, 3/6 peers — artifacto/blog 504 too); serves once the mesh route recovers.
+
 ### 2026-05-31 — `auth.hubris.network` now served locally on the VPS
 Authentik migrated onto the VPS ([investigation](../investigations/2026-05-31-authentik-vps-migration.md)). Unlike the home-backed services above, `auth` is a local container routed via traefik Docker-provider labels with traefik-managed Let's Encrypt — no cert-mirror, no `traefik-dynamic.yaml` router. Admin UI gated by an ipAllowList middleware. Traefik gained a second Docker network (`auth`, `172.30.1.0/24`) to reach it while keeping its DB/Redis isolated from the netbird stack.
