I login web console, usually alert below message:
why alert? how can I resolve it?
Couchbase Server performs some checks to ensure that the DNS domain name resolves to the current IP address it knows about. In this situation the DNS server is not resolving ydd-cbs-0000.ydd-cbs.default.svc.cluster.local. which implies it’s a problem with KubeDNS. I’d start by checking those logs and running any issues by them. The errors should be transient however and should not affect the operation of your Couchbase deployment.
thanks for your reply
