kubernetes1.13.4集成安装heapster

缺乏、安全感 2022-04-24 02:28 197阅读 0赞

### 基础环境 ###

拥有一个完美运行的kubernetes1.13.4集群并已经部署过dashboard，可参考我的部署文章创建自己的集群。

NT:heapster在kubernetes1.8以后不被推荐了，转而推荐使用[metrics-server][]

### 部署步骤 ###

1.  编写部署需要的yaml文件
    
    NT：下面的文件相较于官方文档有改动，解决了国内环境的镜像拉取问题，同时解决了几个小bug。大家可以对比参考。

              selector:
                k8s-app: influxdb
2.  执行命令完成部署
    
        $ ls
        grafana.yaml  heapster-clusterrole.yaml  heapster-rbac.yaml  heapster.yaml  influxdb.yaml
        
        $ kubectl create -f .
3.  等待所有pod的状态达到running，登录dashboard就可以看到图形化界面了。
