  # 定义的是一个 Job 在任意时间最多可以启动多少个 Pod 同时运行
  parallelism: 1
  # 定义的是 Job 至少要完成的 Pod 数目，即 Job 的最小完成数
  completions: 1
  # spec.activeDeadlineSeconds 属性用于设置 Job 运行的超时时间
  # 如果 Job 运行的时间超过了设定的秒数，那么此 Job 就自动停止运行所有的 Pod，并将 Job 退出状态标记为 reason:DeadlineExceeded

  # spec.backoffLimit 用于设置 Job 的容错次数，默认值为 6
  # 当 Job 运行的 Pod 失败次数到达.spec.backoffLimit 次时，Job Controller 不再新建 Pod，直接停止运行这个 Job，将其运行结果标记为 Failure
