LXC 511–513 (nats-a/b/c on 10.10.10.21–23, vmbr1 only) form cluster verae with replicas=3. Host loopback 127.0.0.1:4222 is unchanged. |

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:
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.
# 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.
