I am trying to deploy Elasticsearch and Kibana using ECK operator v1beta1 on a private kubernetes deployment.
I am following https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-overview.html
The yaml files are used as such with only change of using persistent volume claim in elastic search.
Though I am able to get the elastic search up but kibana is failing with error "Unable to revive connection: https://quickstart-es-http.default.svc:9200/
On probing further on ES pod logs I also see the error message javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca.
Is there any other configuration that might be required?
