本篇文章，所使用的任何镜像和yaml我都会发一个网盘链接，供大家下载学习！链接:https://pan.baidu.com/s/1inmW… 密码:92uagithub：https://github.com/heyangguang有任何问题可以直接联系我的Email：heyangev@cn.ibm.comHeapster是一个收集者，将每个Node上的cAdvisor的数据进行汇总，然后导到第三方工具(如InfluxDB)。Heapster介绍架构图：Heapster首先从K8S Master获取集群中所有Node的信息，然后通过这些Node上的kubelet获取有用数据，而kubelet本身的数据则是从cAdvisor得到。所有获取到的数据都被推到Heapster配置的后端存储中，并还支持数据的可视化。现在后端存储 + 可视化的方法，如InfluxDB + grafana。部署实施：下载heapster镜像，上传heapster.yaml、heapster-mod.yaml文件apply就可以了。k8smaster:[root@k8smaster ~]# docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/heapster-amd64:v1.5.4Trying to pull repository registry.cn-hangzhou.aliyuncs.com/google_containers/heapster-amd64 …v1.5.4: Pulling from registry.cn-hangzhou.aliyuncs.com/google_containers/heapster-amd6491380601464e: Pull completef351486260ed: Pull completeDigest: sha256:c4a8d9c0007abb73a1b9e4f9c8bfb044e475aae2b4e6276ab2f8b13959cf6949Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/google_containers/heapster-amd64:v1.5.4[root@k8smaster ~]# lsanaconda-ks.cfg heapster-mod.yaml heapster.yaml images.tar kube-flannel.yml[root@k8smaster ~]# kubectl apply -f heapster.yamlserviceaccount/heapster createdclusterrolebinding.rbac.authorization.k8s.io/heapster createddeployment.apps/heapster createdservice/heapster created[root@k8smaster ~]# kubectl apply -f heapster-mod.yamlWarning: kubectl apply should be used on resource created by either kubectl create –save-config or kubectl applyclusterrole.rbac.authorization.k8s.io/system:heapster configured查看状态：[root@k8smaster ~]# kubectl get pods -n kube-systemNAME READY STATUS RESTARTS AGEcoredns-86c58d9df4-kmfct 1/1 Running 0 23mcoredns-86c58d9df4-qn2k2 1/1 Running 0 23metcd-k8smaster 1/1 Running 0 23mheapster-569b679494-rktzf 1/1 Running 0 18skube-apiserver-k8smaster 1/1 Running 1 22mkube-controller-manager-k8smaster 1/1 Running 0 22mkube-flannel-ds-amd64-9rmfz 1/1 Running 0 19mkube-flannel-ds-amd64-vnwtf 1/1 Running 0 15mkube-flannel-ds-amd64-x7q4s 1/1 Running 0 15mkube-proxy-7zl9n 1/1 Running 0 22mkube-proxy-t2sx9 1/1 Running 0 23mkube-proxy-txsfr 1/1 Running 0 22mkube-scheduler-k8smaster 1/1 Running 0 23m稍等一会，使用kubectl top node查看集群状态即可：[root@k8smaster ~]# kubectl top nodeNAME CPU(cores) CPU% MEMORY(bytes) MEMORY%k8smaster 122m 3% 2848Mi 8%k8snode-1 27m 0% 603Mi 1%k8snode-2 26m 0% 582Mi 1%到这里heapster收集集群数据教程就完成了！希望大家可以给我指出问题，我们一起前进！谢谢大家！
