Thank you for writing this. This is so much better documentation than official documentation.
I have been trying to get it working since yesterday but really stuck on exposing qps. I tried with k8s 1.5.4, k8s 1.0.0-alpha.1 on both minikube and aws. In all cases, I was do not see “Custom Metrics” when I go to pod under http://$(minikube ip):4194/docker/. I used your github repository to create pods.
Can you check if something is missing? Also which k8s version you were using? I am guessing, that you were using 1.5.4
btw, k8s 1.6.x has a built in custom metrics support without heapster. Have you tried that? That may be how it is done in future versions of k8s
