The cluser-ui is not assigned external ip. It throws error Error syncing load balancer: failed to ensure load balancer: unsupported load balancer affinity: ClientIP
Any idea.

Yes I do, AWS is broken and doesn’t allow IP basec client affinity :smiley:

Try setting spec.platform: aws. This will cause the operator not to use client affinity, and will work. Problem is the connection may drop and then be routed to another pod, which will reject the request as Couchbase doesn’t support load balancing on the UI. If this is for HA service discovery, this is fine. only the UI is affected. If you wish to use the UI externally we recommend using a port forward.
