Hi Team,

We have a GKE clusters running on East and West independently .

I have deployed Elastic and Kibana through our org Golden images. My team able to do all operation to create indexes etc on east and west.

East configuration i am pasting here,

             port:

I have similar configuration in west. able to access everything as said before.

Now I want to implement cross cluster replication. If sme one give me steps and example yaml files that will be great help.

I am new to this and seeing your help to setup cross cluster replication.

Your help is greatly appreciated.

Many thanks in advance.

Quick question, do you have a paid license, platinum or enterprise, for both of your clusters?

Cross Cluster Replication is a paid feature and require both clusters to have a paid license.
