Good evening everyone,

My Name is Carlos Ruiz and I've set a DC/OS 1.8.6 lab environment with 3 masters and 3 agent nodes

One of the requirements we got from our customer is to be able to run a cluster with two instances of Elastic 5.x on different nodes.

I know that we can set such cluster running the task in dc/os setting

```
        discovery.zen.ping.unicast.hosts

```

parameter with the name of 2 of the 3 nodes and setting a constraint into those specific nodes, but the preferred option for scalability is to be able to set this configuration on a dynamic way

Have any of you made a configuration like this?, do you have any recipe that you can share or any reference link that I can use?

Thanks in advance for your help

Kind Regards

The usual thing to do is to set that parameter to all the master nodes. You can also use the [file discovery plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/discovery-file.html) to read the hosts dynamically. I'm told that the file based plugin works well for folks in very dynamic environments.
