导语：k8s执行定时任务时日志时间与实际时间差8小时。服务器时区和容器时区均没问题。

发现CronJob的执行时间是根据kube-controller-manager的时间来控制。

需要修改kube-controller-manager的配置，增加挂载

kubeadm初始化的时候加上以下内容

controllerManager: 
  extraArgs:
    pod-eviction-timeout: "30s"
    terminated-pod-gc-threshold: "1"
    enable-hostpath-provisioner: "true" # 增加的参数
  extraVolumes:
  - name: "localtime-volume"
    hostPath: "/etc/localtime"
    mountPath: "/etc/localtime"
    readOnly: true
    pathType: File
dns: {}
etcd:

k8s1.27版本可以添加.spec.timeZone: "Etc/UTC"
