Which can be queried

/ # nslookup bucket
Server:		10.96.0.10
Address:	10.96.0.10:53

bucket.default.svc.cluster.local	canonical name = minio.default.svc.cluster.local
Name:	minio.default.svc.cluster.local
Address: 10.106.87.105

I have not yet tested with bucket traffic.

Tested with latest change.

While this creates a service, what is the plan on deleting the service upon Delete bucket?

The BucketSrvHandler needs to take another query param like delete=true to invoke delete for the service as well..
