如何访问Heapster'；使用Rancher 1.5.1清洁Kubernetes 1.5.0安装后的s Grafana仪表板

我正在使用Rancher 1.5.1在AWS上部署我的测试Kubernetes集群

我首先部署Rancher并确保在主机注册后没有错误。 然后，我使用Rancher目录中的“Kubernetes”条目安装Kubernetes。 这似乎成功了，没有任何错误，我可以访问我的1.5.0 Kubernetes：

kubectl version
Client Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.4", GitCommit:"7243c69eb523aa4377bce883e7c0dd76b84709a1", GitTreeState:"clean", BuildDate:"2017-03-08T02:50:34Z", GoVersion:"go1.8", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"5+", GitVersion:"v1.5.0-115+611cbb22703182", GitCommit:"611cbb22703182611863beda17bf9f3e90afa148", GitTreeState:"clean", BuildDate:"2017-01-13T18:03:00Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}

据我所知，带有XDB和Grafana仪表板的Heapster现在是默认Kubernetes安装的一部分。所有与Heapster、InfluxDB和Grafana相关的POD在日志或状态中均未显示错误，并且似乎已成功运行：

与本Heapster视频中演示的不同：

有人能给我一个提示，说明什么地方可能出错，以及我如何连接到Heapster的Grafana仪表板吗？

看来我必须为系统添加一个正确的入口：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: monitoring-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - host: monitoring.kube-system.mykubernetes.host
    http:
      paths:
      - path:
        backend:
          serviceName: monitoring-grafana
          servicePort: 80

---

是的，几乎所有HTTP服务都应该有入口资源

这缺少名称空间kube系统。
