Is this a BUG REPORT or FEATURE REQUEST?

What happened:

While following the minikube based approach at http://openebs.readthedocs.io/en/latest/install/dev_solutions.html I ran the kubectl apply -f openebs-operator.yaml command. I got the following error:

error: error validating "openebs-operator.yaml": error validating data: unknown object type schema.GroupVersionKind{Group:"", Version:"v1", Kind:"ServiceAccount"}; if you choose to ignore these errors, turn validation off with --validate=false

What you expected to happen:

I would expect it to not produce an error message. However... kubernetes/kubernetes#53309 looks like it bit me.

 kubectl version
Client Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.1", GitCommit:"f38e43b221d08850172a9a4ea785a86a3ffa3b3a", GitTreeState:"clean", BuildDate:"2017-10-12T00:44:36Z", GoVersion:"go1.9.1", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.5", GitCommit:"17d7182a7ccbb167074be7a87f0a68bd00d58d97", GitTreeState:"clean", BuildDate:"2017-09-18T20:30:29Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}

I'm very new to k8s so I think this is probably a bug from using the bleeding edge stuff. Maybe you should mention in your getting started guide if there is a blessed version of k8s, etc. that is recommended.

Following the --validate=false approach unblocked me.

Ah, it's specific to minikube: kubernetes/minikube#1996
