I have a few questions regarding setting up an elastic cluster. I had initially used the scale option to bring up 3 elasticsearch instances but the cluster didn’t seem to form automatically. What I am I missing? Secondly, I’ve had a look at the rancher-compose file for the elasticsearch cluster setup from the catalog what I’m unclear about is what exactly is the job of ‘rancher/elasticsearch-conf:v0.4.0’ and why is it needed? ---

What you are looking for is [here](https://github.com/rancher/catalog-dockerfiles/tree/master/elasticsearch/containers/0.5.0/elasticsearch-conf) in the [catalog-dockerfiles](https://github.com/rancher/catalog-dockerfiles) github repository. The conf container will keep an elasticsearch config up to date reading rancher-metadata service. ---

Thank you, that was actually very help. I’ve now managed to setup a simple three node cluster! Cheers. 🙂
