kubernetes - 如何检查 "kubectl delete"何时因 "timeout waiting for ... to be synced"失败

Question

我有一个 Kubernetes v1.10.2 集群和一个 cronjob。作业配置设置为:

   failedJobsHistoryLimit: 1
  successfulJobsHistoryLimit: 3

但是它创造了十多个工作岗位，都是成功的，并没有自动移除。现在我尝试使用 kubectl delete job XXX 手动删除它们，但命令超时为:

$  kubectl delete job XXX
error: timed out waiting for "XXX" to be synced

我想知道这种情况怎么办。命令执行是否有日志文件？

我只知道kubectl logs命令，但不是针对这种情况。

“kubectl get”显示作业已经完成:

status:
  active: 1
  completionTime: 2018-08-27T21:20:21Z
  conditions:
  - lastProbeTime: 2018-08-27T21:20:21Z
    lastTransitionTime: 2018-08-27T21:20:21Z
    status: "True"
    type: Complete
  failed: 3
  startTime: 2018-08-27T01:00:00Z
  succeeded: 1

和“kubectl describe”输出为:

$ kubectl describe job test-elk-xxx-1535331600 -ntest

说明还有一个pod在运行，但是我不知道怎么弄出pod的名字。

Answer 1

检查是否kubectl describe pod <pod name> (作业的关联 pod)仍然会返回一些东西，这将:

• 表示节点还在
• 包括 pod condition

在那个状态下，你可以考虑 a force deletion .
