ElasticSearch Couchbase复制问题

Question

I have a problem with my ElasticSearch cluster in Couchbase XDCR configuration.

I put private ip 10.28.0.21 as IP ( my elasticsearch and couchbase in the same server) when creating cluster reference. Then the system change that by public IP (92.222..) of my server. It is very strange. I don't know why?

Couchbase logs show :

Updated remote cluster 'ElasticSearch' hostname to "92.222..:9091" because old one ("10.28.0.21:9091") is not part of the cluster anymore

Thanks for any suggestions.

Couchbase uses the IP that ElasticSearch returns as its host address. If you want ElasticSearch to publish the private IP instead of the public, you can override it with the network.publish_host setting in elasticsearch.yml. If the private IP isn't static, you might have to set it to the IP of a particular network interface, such as _eth0_ .
