How to Configure ReadonlyRest for 4 node Elasticsearch Cluster


I am trying to configure ReadonlyRest plugin for our Elasticsearch 4 node cluster.

Basically my goal is to forward logs to Elasticsearch through HTTPS from all the sources like Kubernetes, Nginx and Jenkins machines, and also access Elasticsearch from kibana with HTTPS.

We want access Elastic by providing certs not username and password.

We have our own SSL tool to generate certificates.

Could someone please give me some idea what are/kind the certificates needs to generate for Elastic Cluster to access Elastic cluster from outside through HTTPs and also node to node communication through HTTPS.

I have installed Elastic and kibana 6.5.4 versions.

The client cert verification will be available in the next release.
