普罗米修斯-Kubernetes RBAC

Question

我将我的GKE API服务器升级到1.6，并正在将节点升级到1.6，但遇到了一个障碍...

我有一个prometheus服务器（版本1.5.2)，运行在一个由Kubernetes部署管理的pod中，其中两个节点运行版本1.5.4Kubelet，一个新节点运行版本1.6。

apiVersion: v1
kind: ServiceAccount
metadata:
  name: prometheus

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRole
metadata:
  name: prometheus
rules:
- apiGroups: [""]
  resources:
  - nodes
  - services
  - endpoints
  - pods
  verbs: ["get", "list", "watch"]
- apiGroups: [""]
  resources:
  - configmaps
  verbs: ["get"]
- nonResourceURLs: ["/metrics"]
  verbs: ["get"]

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding

    matchLabels:
      app: prometheus-prometheus
      component: server

      maxUnavailable: 1

      restartPolicy: Always
      schedulerName: default-scheduler
      serviceAccount: prometheus
      serviceAccountName: prometheus
      ...

但普罗米修斯仍然得到401。

更新：就像乔丹所说的kubernetes认证问题。在这里看到新的、更集中的问题；https://serverfault.com/questions/843751/kubernetes-node-metrics-endpoint-returns-401

Answer 1

401表示未经身份验证，这意味着它不是RBAC问题。我相信GKE不再允许匿名访问1.6中的kubelet。您使用什么凭据对Kubelet进行身份验证？
