# Disaster recovery

Doel: volledige **atc-docker01** dashboard-stack en configuratie terugzetten vanuit git.

## Vereisten

- VM `atc-docker01` met Docker en git
- Netwerk naar interne `.dell-atc.lan` hosts
- Secrets: `.env` of bestaande `config/homepage/proxmox.yaml`

## Stap 1 — Repository

```bash
dnf install -y git docker-compose-plugin   # of equivalent
git clone http://atc-mgt01.dell-atc.lan:3001/mo/Lakehouse.git /root/lakehouse
cd /root/lakehouse
cp .env.example .env
# Bewerk .env: SUPERSET_SECRET_KEY, eventueel Proxmox token
```

## Stap 2 — Homepage + RSS + icons

```bash
docker compose -f deploy/docker-compose.homepage.yml up -d --build
docker exec homepage wget -qO- http://127.0.0.1:3000/api/revalidate
```

## Stap 3 — Superset

```bash
docker compose -f compose/superset/docker-compose.yaml up -d --build
```

## Stap 4 — Optioneel: Forgejo, LAM, cAdvisor

```bash
docker compose -f compose/forgejo/compose.yaml up -d
docker compose -f compose/lam/compose.yml up -d
# docker compose -f compose/cadvisor/compose.yaml up -d
```

Of alles tegelijk:

```bash
./scripts/deploy/deploy-atc-docker01.sh
```

## Stap 5 — Andere hosts (handmatig)

Deze repo bevat **config-referenties**, geen volledige VM-images:

| Host | Herstel uit git |
|------|-----------------|
| Kafka connectors | `config/kafka/*.json` → deploy op Connect API |
| Trino | `config/trino/config.properties` → `/etc/trino/` op lake01 |
| Spark | `config/spark/spark-defaults.conf` |
| Airflow | `config/airflow/` |
| Data scripts | `config/scripts/data-generation/` |

Zie `inventory/containers-atc-docker01.json` voor laatst geëxporteerde containerstate.

## Volumes (niet in git)

Back-up apart:

- `forgejo_forgejo` — Git data
- `superset_superset_home` — Superset metadata
- `lam_lam` — LAM configuratie

```bash
docker run --rm -v forgejo_forgejo:/data -v /backup:/backup alpine \
  tar czf /backup/forgejo_forgejo.tgz -C /data .
```

## Verificatie

1. http://atc-docker01.dell-atc.lan/ — homepage laadt, 4 tabs
2. http://atc-docker01.dell-atc.lan:8090/health — RSS proxy
3. http://atc-docker01.dell-atc.lan:8088/health — Superset
4. FEEDS-tab toont RSS-widgets

## Proxmox-widget

Token staat in `config/homepage/proxmox.yaml`. Na restore: Proxmox → Permissions → API Tokens → controleer `root@pam!homepage`.
