"kubectl top pods" requires heapster - reinstate addon?

[tstromberg]

The heapster addon was removed some time ago due to it being deprecated. I guess it isn't deprecated enough!

kubectl top pods
Error from server (NotFound): the server could not find the requested resource (get services http:heapster:)

$ minikube addons enable heapster
💣  enable failed: run callbacks: heapster is not a valid addon

😿  minikube is exiting due to an error. If the above message is not useful, open an issue:

$ kubectl version

I think this is about kubernetes(kubectl?) issue. It is confusing output(All we need is metrics-server not heapster).
With minikube's metrics-server addon, we can get top pod & top node.

$ minikube start

$ kubectl top pods
Error from server (NotFound): the server could not find the requested resource (get services http:heapster:)

$ minikube addons enable metrics-server
🌟  The 'metrics-server' addon is enabled

(〜wait for some minutes〜)

$ kubectl top pods -n kube-system
NAME                               CPU(cores)   MEMORY(bytes)
coredns-66bff467f8-c6wwn           3m           6Mi
coredns-66bff467f8-rbwzf           4m           6Mi
etcd-minikube                      23m          27Mi
kube-apiserver-minikube            54m          256Mi

kube-proxy-dwdwd                   0m           8Mi
kube-scheduler-minikube            4m           10Mi
metrics-server-7bc6d75975-2m29p    0m           9Mi
storage-provisioner                0m           16Mi

Or should we enable metrics-server addon as default to avoid this issue?

Thanks! Perhaps we could make heapster an alias for metrics-server, or make an error message that says "heapster's functionality has been replaced by metrics-server".

I’d like to work on this issue.

Do we have similar alias addon such like this?
If there is, I'll refer to it.
If nothing, I'll try anyway.
