metrics-server最新版本有坑，慎用

参考文档：https://www.jianshu.com/p/262177fa9320

版本：metrics-server-amd64:v0.3.3

          addon-resizer:1.8.4

[root@master metrics]# vim metrics-server-deployment.yaml 

查看：

莫名其妙的一对报错，不错最终搞好了。

毫无里头报错：

[root@master ~]# kubectl logs metrics-server-v0.3.3-856bb6d5f8-55dbc -c  metrics-server -n kube-system

[root@master ~]# kubectl logs metrics-server-v0.3.3-6448dcfb78-rrhd8 -c metrics-server-nanny -n kube-system

ERROR: logging before flag.Parse: I0528 06:16:58.415375       1 pod_nanny.go:138] Resources: [{Base:{i:{value:80 scale:-3} d:{Dec:} s:80m Format:DecimalSI} ExtraPerNode:{i:{value:5 scale:-4} d:{Dec:} s: Format:DecimalSI} Name:cpu} {Base:{i:{value:83886080 scale:0} d:{Dec:} s: Format:BinarySI} ExtraPerNode:{i:{value:8388608 scale:0} d:{Dec:} s: Format:BinarySI} Name:memory}]

 需要修改的配置

[root@master metrics]# vim metrics-server-deployment.yaml

[root@master metrics]# vim resource-reader.yaml    增加  - nodes/stats，

 

 

测试正常显示：

[root@master yaml]# kubectl proxy --port=8080

[root@master ~]# kubectl top nodes
