I use skydns as my nameserver, and I can resolv the jenkinshift on the nameserver
`# kubectl exec busybox -- nslookup jenkinshift
Server: 172.16.0.2
Address 1: 172.16.0.2 kube-dns.kube-system.svc.bigbigcloud.cn

Name: jenkinshift
Address 1: 172.16.219.86 jenkinshift.default.svc.bigbigcloud.cn`

And on my kubernetes service
`# kubectl get service jenkinshift

NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE

jenkinshift 172.16.219.86 80/TCP 17h`

On my fabric8 server
`# kubectl exec fabric8-og6b1 -- cat /etc/resolv.conf
search default.svc.bigbigcloud.cn svc.bigbigcloud.cn bigbigcloud.cn

nameserver 172.16.0.2

nameserver 8.8.8.8

options timeout:1 attempts:1 rotate

options ndots:5`
