# homelab-gateway
|
|
|
|
Telegram **webhook gateway** for the Arcodange home lab. Replaces polling-based
|
|
bots (e.g. those scheduled in Cowork) with direct webhook delivery from
|
|
Telegram, routed to per-bot handlers running on the k3s cluster.
|
|
|
|
> Phase 1 (MVP): single sync `echo` handler, end-to-end flow validated.
|
|
> Phase 2 (planned): `http` forward handler + Postgres-backed durable queue.
|
|
> Phase 3 (planned): async `shell` / `script` / `ollama` handlers.
|
|
|
|
See the design doc at `~/.claude/plans/pour-les-notifications-on-inherited-seal.md`.
|
|
|
|
## Architecture (current)
|
|
|
|
```
|
|
Telegram → Cloudflare Tunnel (tg.arcodange.fr) → Service homelab-gateway:8080
|
|
→ /bot/<slug> → secret_token check → handler dispatch → Bot API sendMessage
|
|
```
|
|
|
|
## Routes
|
|
|
|
| Method | Path | Description |
|
|
|--------|------------------|--------------------------------------------|
|
|
| GET | `/healthz` | Liveness probe |
|
|
| GET | `/readyz` | Readiness probe |
|
|
| POST | `/bot/{slug}` | Telegram webhook entry (validates secret) |
|
|
|
|
## Local dev
|
|
|
|
```bash
|
|
# 1. Provide a config + env
|
|
export BOT_FACTORY_TOKEN='8737289837:…' # from @BotFather
|
|
export BOT_FACTORY_SECRET=$(openssl rand -hex 32)
|
|
|
|
# 2. Run
|
|
make run # uses bots.example.yaml
|
|
|
|
# 3. Smoke a webhook
|
|
curl -X POST -H "X-Telegram-Bot-Api-Secret-Token: $BOT_FACTORY_SECRET" \
|
|
-H 'Content-Type: application/json' \
|
|
-d '{"update_id":1,"message":{"chat":{"id":<your-chat-id>},"text":"hi"}}' \
|
|
http://localhost:8080/bot/factory
|
|
```
|
|
|
|
## Set / delete webhook
|
|
|
|
```bash
|
|
# Once the gateway is reachable at https://tg.arcodange.fr:
|
|
export BOT_FACTORY_TOKEN=…
|
|
export BOT_FACTORY_SECRET=…
|
|
make setwebhook SLUG=factory BASE_URL=https://tg.arcodange.fr
|
|
make deletewebhook SLUG=factory
|
|
```
|
|
|
|
## Configuration
|
|
|
|
- **Routing** (non-secret): YAML at `$CONFIG_PATH` (default
|
|
`/etc/homelab-gateway/bots.yaml`, mounted from a ConfigMap in cluster).
|
|
- **Secrets**: per-bot env vars `BOT_<UPPER_SLUG>_TOKEN`,
|
|
`BOT_<UPPER_SLUG>_SECRET`. Sourced from Vault path
|
|
`kvv2/homelab-gateway/config` via Vault Secrets Operator.
|
|
|
|
## Cluster deploy
|
|
|
|
- Image: `gitea.arcodange.lab/arcodange/homelab-gateway:<tag>`
|
|
- Helm chart: `chart/`
|
|
- ArgoCD app: `homelab-gateway` (in `factory/argocd/values.yaml`)
|
|
- Public URL: `https://tg.arcodange.fr` (Cloudflare déjà configuré pour
|
|
router `*.arcodange.fr` vers le home lab → Traefik route par Host)
|
|
- Secrets Phase 1 : `kubectl create secret generic homelab-gateway-bots …`
|
|
(sans Vault). Migration vers Vault Secrets Operator en Phase 2+ via
|
|
`vault.enabled: true` dans `chart/values.yaml`.
|
|
|
|
Voir `DEPLOY.md` pour la procédure end-to-end.
