安装prometheus监控Kubernetes集群报错

Question

我正在安装prometheus来监控K8S但是我遇到了这个错误。你能帮助我吗？非常感谢！！

helm version
Client: &version.Version{SemVer:"v2.13.0", 
GitCommit:"79d07943b03aea2b76c12644b4b54733bc5958d6", GitTreeState:"clean"}

GitCommit:"79d07943b03aea2b76c12644b4b54733bc5958d6", GitTreeState:"clean"}

helm install stable/prometheus-operator --name prometheus-operator --namespace monitoring

Error: customresourcedefinitions.apiextensions.k8s.io "alertmanagers.monitoring.coreos.com" is forbidden: User "system:serviceaccount:kube-system:default" cannot delete resource "customresourcedefinitions" in API group "apiextensions.k8s.io" at the cluster scope

这是典型的情况，当部署 Tiller（Helm 设置的服务器端）时没有具有适当集群角色（集群管理员）的服务帐户。

您需要先修复您的 Helm 设置，才能继续进行 prometheus-operator 安装，如所述here，或通过运行直接一一执行以下命令：

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
