Here’s the first one:

[Download the 1-command installer bundle](sandbox:/mnt/data/pg_one_command_installer.zip)

What’s inside:

* `scripts/install-node.sh` — one-command installer for either a DB node or the proxy node
* `examples/db1.env` — sample DB node config
* `examples/proxy1.env` — sample proxy config
* `README.md` — quick usage notes

How to use it on each VPS:

```bash
unzip pg_one_command_installer.zip
cd pg_one_command_installer
sudo bash scripts/install-node.sh examples/db1.env
```

For the proxy:

```bash
sudo bash scripts/install-node.sh examples/proxy1.env
```

Before running:

* edit the env file
* fill in public IPs
* fill in WireGuard keys
* fill in Caddy bcrypt hashes
* change passwords

Next, I’ll do **auto HAProxy update on node add/remove**.
