I have heapster installed on kubernetes, i am trying to autoscale my pods.. but i keep seeing the following:

unable to get metrics for resource cpu: unable to fetch metrics from resource metrics API: the server could not find the requested resource (get pods.metrics.k8s.io)

The heapster service itself

I want to have autoscaling working with kubernetes, anyone have any ideas?

I know heapster is deprecated, but as of now i cannot chnage or upgrade to metrics server.. so could do with some help
