Kubernetes 1.8.4中如何安装Heapster

这篇文章给大家分享的是有关Kubernetes 1.8.4中如何安装Heapster的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

Heapster

Heapster 是 Kubernetes 社区维护的容器集群监控分析工具。Heapster 会从 Kubernetes apiserver 获得所有 Node 信息，然后再通过这些 Node 来获得 kubelet 上的数据，最后再将所有收集到数据送到 Heapster 的后台储存 InfluxDB，最后利用 Grafana 来抓取 InfluxDB 的数据源来进行可视化。

• 在master通过 kubectl 来创建 kubernetes monitor 即可
  生成kube-heapster.yml

  kubectl apply -f kube-heapster.yml

  查看状态

  kubectl -n kube-system get po,svc

  
  

  完成后，就可以通过浏览器访问Grafana Dashboard

  https://10.0.0.162:6443/api/v1/proxy/namespaces/kube-system/services/monitoring-grafana
