网速太卡可以选择以下方式

git clone https://gitee.com/jbjb123/draft.git

cd draft/kube-state-metrics/
 kubectl apply -f .
deployment.apps/kube-state-metrics unchanged
serviceaccount/kube-state-metrics unchanged
clusterrole.rbac.authorization.k8s.io/kube-state-metrics unchanged
clusterrolebinding.rbac.authorization.k8s.io/kube-state-metrics unchanged

[root@build32-8 monit]# kubectl get pods -n kube-system | grep kube-state
