Hello All,

I was wondering what this two node cluster setup in docker (and I assume on one physical host) - as described here: [https://www.elastic.co/guide/en/elasticsearch/reference/5.2/docker.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/docker.html) - , is good for? does it provide redundancy? I thought the minimum of nodes required in a cluster was 3?

Regards

It is. This is just an example on how you can run multiple nodes, with the expectation that you'd start another node.
