I tried to find the doc for deploying multiple instances of weaviate in different machine inside single LAN environment to make a cluster. The example I find is on ONE machine docker compose for three instance. Any chance you could point me to the right doc for multiple servers? I would like to test deploy to our Google Cloud.

### Description

### Server Setup Information

- Weaviate Server Version:
- Deployment Method: 
- Multi Node? Number of Running Nodes:
- Client Language and Version:

### Any additional Information

Hi Lawrence!

Considering the latest 1.25 version, that introduced RAFT consensus as a way to choose a lider in the Cluster, you will need to define some of those variables:

> **[Environment variables | Weaviate - Vector Database](https://weaviate.io/developers/weaviate/config-refs/env-vars#multi-node-instances)**
>
> To configure Weaviate in a Docker or a Kubernetes deployment, set these environment variables

the main variable being: `RAFT_JOIN`

With those set, as long as each node can communicate with the other nodes from that cluster, it should work.

Thanks!

Cool… will do the test very soon and see how it goes.

Checked it. And yes, RAFT\_JOIN is one of the key to set in dockerfile. The only thing left is how to set the IP address (or DNS name) of weaviate-1 (as cluster master) in weaviate-2 or weaviate-3’s docker file. I know the environment variable could set the port and others.

you can set those at /etc/hosts with corresponding ips for each machine.
