I`m using Elasticsearch 2.2.0 with shield 2.2. The cluster has a 100 nodes on different servers in AWS environment under one domain:
es1.test.domainname.com es2.test.domainname.com es3.test.domainname.com es4.test.domainname.com es5.test.domainname.com es6.test.domainname.com ... es99.test.domainname.com es100.test.domainname.com
I want to enable ssl in Shield and for that I need to issue a signed certificate as I already described in other question. The problem here is that for each new elastic node I would need to issue new signed certificate so the node could join the ssl protected cluster… Right now I have already “spent” all of my weekly subdomains requests.
Is it possible to sign only one certificate for test.domainname.com and copy it to all the other nodes (different servers same domain)?
