Elastic Search - Lookup Nodes

I am going through the documentation of network settings - I had few queries with respect to the best practices .

  1. Should the nodes be assigned static ip address for other nodes to reach out reliably or
  2. DNS lookup
  3. Doesn't matter the nodes going up or down

What should be the best practise

Do you mean coordinating nodes?

You'd be better off using DNS with multiple cnames, or a loadbalancer. That way you can add/remove nodes as needed and not have to change your clients.

is the same applies for within the cluster to avoid depending on IP addresses for look ups ?

What version are you on?


It's really up to you how you manage this. It might make sense for your use case, but if you have your cluster deployment automated, it probably won't matter a lot.
