# verae-nats-cluster
Three **distinct Proxmox LXC** guests running **NATS JetStream** as a cluster, on the private bridge only. This is the test stand before the same layout moves to separate hardware.
**Forgejo:** https://git.georgelambert.org/marchon/verae-nats-cluster
**SSH:** `ssh://git@git.georgelambert.org:2223/marchon/verae-nats-cluster.git`
| Guest | VMID | `vmbr1` IP | Client | Cluster | Monitor |
|-------|------|------------|--------|---------|---------|
| nats-a | 511 | 10.10.10.21 | `:4222` | `:6222` | `127.0.0.1:8222` |
| nats-b | 512 | 10.10.10.22 | `:4222` | `:6222` | `127.0.0.1:8222` |
| nats-c | 513 | 10.10.10.23 | `:4222` | `:6222` | `127.0.0.1:8222` |
Cluster name: `verae`. Client URL:
```text
nats://10.10.10.21:4222,nats://10.10.10.22:4222,nats://10.10.10.23:4222
```
**Not** on `vmbr0`. **Not** `0.0.0.0`. Host lab NATS on `127.0.0.1:4222` is left running so current keep/fleet/middleware stay up until you cut over.
```bash
# on NS1 (the Proxmox host)
git clone ssh://git@git.georgelambert.org:2223/marchon/verae-nats-cluster.git
cd verae-nats-cluster
bash scripts/create-cluster.sh
bash scripts/status.sh
bash scripts/test.sh
```
Cut over a worker later with `NATS_URL=nats://10.10.10.21:4222,nats://10.10.10.22:4222,nats://10.10.10.23:4222` (for example `px-worker`). Zapier cloud never talks to NATS.
Hardware move: same three configs, three boxes, private NIC only — change IPs in `cluster.env` and `conf/nats.conf.tmpl`.
