## How it works
1. Starts all 5 VMs via `POST /api2/json/nodes/{node}/qemu/{vmid}/status/start`
2. Waits for port 22 to open on each VM (`nc -z`)

Proxmox credentials (`pve1Endpoint`, `pve1ApiToken`, `pve2Endpoint`, `pve2ApiToken`) are read automatically from the `proxmox-infra` stack outputs via StackReference — do **not** set them here.
## Deployment order
`proxmox-infra` must be deployed **before** k8s-bootstrap. The proxmox-infra stack exports the Proxmox credentials and VM IDs that k8s-bootstrap reads via StackReference. If proxmox-infra hasn't been re-deployed after its latest code changes, those outputs won't exist and k8s-bootstrap will fail.
In CI, both workflows run as previews on PRs (no deploy). Trigger `workflow_dispatch` on `deploy-proxmox-infra` first, then run k8s-bootstrap.
After setting config, re-encode `Pulumi.dev.yaml` and update the Gitea secret `K8S_BOOTSTRAP_DEV_YAML`:
