# 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.

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`.
