# cast01–cast03 lab cluster

**Runbook:** [DEPLOY.md](DEPLOY.md) — unattended populate & verify.

Quick start on a fresh node:

```sh
sudo install -m 644 bootstrap/cluster0-bootstrap.env /etc/cast-cluster.env   # once, before NFS
sudo sh /shared/cluster/populate_lab_setup.sh                                 # or --coordinator
sudo sh /shared/cluster/verify_lab_setup.sh --local
# after DNS:
sudo sh /shared/cluster/verify_global_setup.sh
```

See `ARCHITECTURE.md` for topology and `cluster.env` for cluster-specific settings.

**Journal:** every setup action is logged under `/shared/journal/` with **OK** / **NOK** — readable from FE if VMs are down. See `/shared/journal/README.md`.
