Heapster+influxdb+grafana Construction

The entire architecture is dashboard to detect Hepster service services, Heapster through Cadvisor collects data into the influxdb. Instead, dashboard accesses the 8086 port of the Heapster Svc to get the data drawing.

Prepare Yaml

Problems that appear UI graphics do not show

Dashboard log: Dashboard will go to Heapster's 8082 port to get the data to show the graphics. I can't see heapster here, but Heapster's log is fine.

When dashboard is created, Access does not appear in the UI

I use the Https://raw.githubusercontent.com/kubernetes/dashboard/v1.8.1/src/deploy/recommended/kubernetes-dashboard.yaml of the reference website
