• VM Driver (e.g. cat ~/.minikube/machines/minikube/config.json | grep DriverName): virtualbox

What happened:

$ minikube start
....
$ kubectl cluster-info
Kubernetes master is running at https://192.168.99.102:8443
error: group map[authorization.k8s.io:0xc4203db030 certificates.k8s.io:0xc4203db2d0 federation:0xc4203da930 authentication.k8s.io:0xc4203daee0 autoscaling:0xc4203db0a0 batch:0xc4203db260 componentconfig:0xc4203db340 extensions:0xc4203a6070 policy:0xc4203a60e0 rbac.authorization.k8s.io:0xc4203a6150 :0xc4203dae00 apps:0xc4203dae70 storage.k8s.io:0xc4203a61c0] is already registered

What you expected to happen:

kubectl cluster-info should not output an error

How to reproduce it (as minimally and precisely as possible):

minikube start; kubectl cluster-info (was able to reproduce 3 times... minikube delete, deleted ~/.minikube, etc. and still getting the error on a fresh minikube start).

Fixed by updating kubectl (I had an old version... v1.4)

Also fixed by updating {{kubectl}}
