I am running an Elastic stack in Docker swarm.  
I want to setup authentication in Kibana (username + password atleast), but to do that I need to set security in Elasticsearch first.

What is the best approach to do it in Docker swarm?

The thing is that communication between Docker swarm nodes in already [encrypted](https://docs.docker.com/engine/swarm/how-swarm-mode-works/pki/#:~:text=)

Wouldn't setting an additional security in Elasticsearch be overkill?

Is there a way to not do it and still secure Kibana with authentication?
