turn validation off with --validate=false

[rhohubbuild]

my host OS ubuntu 16.04, i followed docs
1)http://kubernetes.io/docs/getting-started-guides/docker/
then
2) http://kubernetes.io/docs/getting-started-guides/docker-multinode/deployDNS/

i got error when i try this
3) user@host:~/kubernetes$ kubectl create -f ./skydns.yaml
error validating "./skydns.yaml": error validating data: [unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object, unexpected type: object]; if you choose to ignore these errors, turn validation off with --validate=false

then i did
4) user@host:~/kubernetes$ kubectl create -f ./skydns.yaml --validate=false
replicationcontroller "kube-dns-v10" created
service "kube-dns" created

Am i going in correct way ?
if not then how to fix this issue (without using --validate=false flag)?

I meet this issue before, and it is mostly because I am using an outdated kubectl.
