I have installed Docker v17.06-ce on 2 minion nodes plus a master node and Kubernetes with Kubeadm v1.7.0. Then I deployed Web UI (Dashboard) with kubectl create -f https://git.io/kube-dashboard and changed type to NodePort using kubectl edit service kubernetes-dashboard -n kube-system.

I can access it but its missing CPU/Memory usage graphs. So I've followed the instructions from Kuberenets Web UI (Dashboard) missing graphs to deploy heapster and influxdb, but I still can't see the graps...

What's going wrong?

UPDATE: checking logs kubectl logs heapster-2994581613-m28hh --namespace=kube-system I've found these errors repeatedly:

Any idea?
