Oh I tell a lie, when it's not exposed the default value is "".  Your CNI plugin appears to again be not working.  Do a kubectl get svc cb-example-ui -o yaml and see what it shows as its node port...

Simon Murray, Please check yaml content below

Oh I see, that would have raised an error on all other platforms Again because you aren't running the dynamic admission controller you haven't got working defaults added to the adminConsoleServiceType, e.g. NodePort https://docs.couchbase.com/operator/1.2/couchbase-cluster-config.html#adminconsoleservicetype

Thanks Simon Murray,

I'm able to access GUI after doing changes to couchbase-cluster.yaml file.

[root@k8-crdl-master scripts]# kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cb-example ClusterIP None <none> 8091/TCP,18091/TCP 4h40m
cb-example-srv ClusterIP None <none> 11210/TCP,11207/TCP 4h40m
cb-example-ui NodePort 10.100.34.45 <none> 8091:31502/TCP,18091:32709/TCP 4h40m

kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5h29m

Nothing found with the product so closing.

In future until we have determined there is a new feature required or an existing bug the forums (https://forums.couchbase.com/) is the most appropriate place for these queries, or if you have an enterprise account raise an issue via the customer portal.

Thanks!
