无法使用 metricbeat 获取 kubernetes 资源 "events"，出现错误 "Failure 403 events is forbidden:"

Question

我正在配置我的 EFK 堆栈以保留所有与 Kubernetes 相关的日志，包括事件。我搜索并找到了 metricbeat 配置文件并将其部署到我的集群中。

问题：除 "event" 资源外，所有其他 metricbeat 模块都工作正常。我可以看到来自 status_pod、status_node 等的日志，但没有可用于事件模块的日志。

错误：2019/09/04 11:53:23.961693 watcher.go:52: ERR kubernetes: List API error kubernetes api: Failure 403 events is forbidden: User "system:serviceaccount:kube-system:default" cannot list resource "events" in API group "" at the cluster scope

我的 metricbeat.yml 文件：

Answer 1

您是运行使用默认服务帐户的部署。
在部署定义的 spec.serviceAccountName 字段中设置 ServiceAccount 的名称。

kind: Deployment
metadata:
  name: metricbeat
  namespace: kube-system
  labels:
    k8s-app: metricbeat
    kubernetes.io/cluster-service: "true"
spec:
  template:
    metadata:
      labels:
        k8s-app: metricbeat
        kubernetes.io/cluster-service: "true"
    spec:
        serviceAccountName: metricbeat   **<<---  here**

也许您还需要在 ClusterRole 定义中添加资源 pods/log
