We have 3 node cluster as followes
3 Master-eligible nodes - node1,node2,node3
3 Data nodes - node1,node2,node3
Kibana is running on node3
We have to configure SSL in to make the communication secure.
I have followed the given steps in this blog : https://www.elastic.co/blog/elasticsearch-security-configure-tls-ssl-pki-authentication.
we have generated .key .cer files for all 3 nodes,now how to create a single singed CA file to trust all nodes certificates is my doubt
Another question is how to create a Client certificate , that is for Kibana ?
I have gone through several documents and blogs but couldn't find 3 node cluster with HTTPS . Please give me detailed explanation if possible with the steps!!
