在K8S集群部署kube-state-metrics微服务的时候,发现容器日志不停刷报错日志,主要报错日志如下:

发现是kube-state-metrics在集群权限不足;
在github上下载的yaml文件在执行clusterrolebing那一步,并没有给kube-state-metrics提供cluster层级的权限;
执行如下命令,给system:serviceaccount:monitoring:kube-state-metrics做clusterrolebing
kubectl create clusterrolebinding kube-state-metrics-admin-binding \
--clusterrole=cluster-admin \
--user=system:serviceaccount:monitoring:kube-state-metrics
