Does not scrape any node or pods #17

Hi,

i'm just deployed Kubernetes Dashboard 2.0.0-beta1 with this scraper 1.0.0 and in logs i see Database updated: 0 nodes, 0 pods but there are 3 nodes and lots of pods. And yes metrics-server is deployed in cluster. It's AWS EKS 1.13.7 cluster. Maybe i'm just doing something wrong.

For deployment i used this template: https://github.com/kubernetes/dashboard/blob/v2.0.0-beta1/aio/deploy/recommended.yaml

Two things that come to mind.

Some RBAC config preventing scraper from hitting the metrics API
Metrics Server isn't capturing anything (I personally doubt this, it's pretty solid)

Is there anything else in the scraper or metrics-server logs? Also, could you possibly do something like kubectl proxy and try to hit the metrics.k8s.io endpoint yourself? If you need any guidance with that, just ping me. :)

Thanks!

Thank you. So i made some research and debugging and problem is with metrics server resp. wit whole cluster because DNS in cluster is not able resolve *.*.compute.internal domains. So my problem is not related to metrics-scraper. One more time thank you.
