Reference
我想添加audit-policy-file参数,并且文件位于/etc/kubernetes/audit-policy.yaml中
它具有基本的元数据记录规则。
但是,一旦我重新启动服务apiserver不会出现。如果我将值保留为空,则工作正常,并登录/ var / log / containers表示文件读取失败。

最佳答案
您正在将kube-apiserver
作为Pod运行,因此它正在容器内的文件系统上查找该审计文件,而将其放在主机的文件系统上。您需要将该路径安装到kube-apiserver
pod中。假设您正在使用kubeadm
,请将以下内容添加到ClusterConfiguration
中:
apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
apiServer:
extraVolumes:
- name: audit-policy
hostPath: /etc/kubernetes/audit-policy.yaml
mountPath: /etc/kubernetes/audit-policy.yaml
readOnly: true
