## Noder
Palett: **nextcloud collabora** — sex noder i samma lila, alla kopplade till **nc-collab-config** (kugghjul, inte flödesnod).
`nc-collab-config` · `collabora-bridge` · `nc-office` · `collabora-convert` · `collabora-extract` · `collabora-transform` · `collabora-wopi`
Full förklaring och exempel: **[docs/NODES.md](docs/NODES.md)** · importera **[flows/example-flows.json](flows/example-flows.json)**
## Installera på valfri Nextcloud-VM
Kopiera `.env.example` → `.env` och sätt minst `NEXTCLOUD_URL`. Resten detekteras:
| Variabel | Default / auto |
|----------|----------------|
| `NODERED_DIR` | compose-label eller `/home/ncadmin/nextcloud-node-red` |
| `CODE_CONTAINER` | `code` |
| `COLLABORA_IP` | bridge-IP via `docker inspect` |
| `NODERED_CONTAINER` | `nextcloud-node-red` |
| `NODERED_PORT` | `1880` |
```bash
cd /home/ncadmin/nextcloud-collabora-nodered
cp .env.example .env # justera NEXTCLOUD_URL per VM
git pull
./install.sh # root/sudo för docker compose
```
