docker - Kubernetes Web UI(仪表板)不显示图表

Question

我已经在 2 个 minion 节点以及一个主节点和带有 Kubeadm v1.7.0 的 Kubernetes 上安装了 Docker v17.06-ce。然后我使用 kubectl create -f https://git.io/kube-dashboard 部署了 Web UI(仪表板)并使用 kubectl edit service kubernetes-dashboard -n kube-system 将类型更改为 NodePort .

我可以访问它，但缺少 CPU/内存使用图。所以我按照 Kuberenets Web UI (Dashboard) missing graphs 的说明进行操作部署 heapster 和 influxdb，但我仍然看不到图表...

出了什么问题？

更新:检查日志kubectl logs heapster-2994581613-m28hh --namespace=kube-system我反复发现这些错误:

有什么想法吗？

您需要安装heapster pod。尝试安装并检查。

还安装 heapster rbac。

kubectl  create -f https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/rbac/heapster-rbac.yaml

kubectl create -f https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/heapster.yaml
