在上次跑路之后, 用了一个星期自己的K8S集群之后发现,

TM的腾讯云居然连k8s监控都没给我..

反手开了工单之后告诉我, 他们自己实现了一套监控, 所以原生的不自带了.

纳尼....

所以我的kubectl top node/pod都没法用啦?

打人了打人了.

反手搜了一下,

最新的k8s 容器性能指标已经是

kubernetes-incubator/metrics-servergithub.com

那就自己部署一下吧.

git clone https://github.com/kubernetes-incubator/metrics-server.git

# Kubernetes 1.7 $ kubectl create -f deploy/1.7/ # Kubernetes > 1.8 $ kubectl create -f deploy/1.8+/

然而....

并没有能用, 直接error了.

纳尼....

反手一搜..

Metric server pod getting following error.
