How is this going？

Looks like "kubectl version" doesn't format the versions properly on SUSE. Can you open an issue on https://github.com/kubernetes/kubernetes?

[jackhaibo]

Got that, I will open it soon. @xing-yang

@saad-ali please take a look at this issue, thanks

[xing-yang]

The code that caused the panic is in kubernetes-incubator/external-storage/lib/controller/controller.go where it calls utilversion.MustParseSemantic to check the version and decides what feature is supported. If we change that to utilversion.ParseSemantic, it can avoid throwing a panic but it still can't find the version and determine whether a feature is supported or not.

The problem here is "kubectl version" doesn't display version info on a SUSE setup while running K8S local cluster. It could be that local cluster doesn't support SUSE.

From the linked bug it sounds like the problem is with the suse build.
