      apiVersion 定义了该对象表示形式的版本化模式（schema）。服务器应将已识别的模式转换为最新的内部值，

      selector is the label query over pods that should match the replicas count. This is same as the label selector but in the string format to avoid introspection by clients.

      selector 是针对 Pod 的标签查询，用于匹配副本数量。它与标签选择器（label selector）相同，
      但采用字符串格式，以避免客户端进行内省（introspection）。该字符串的格式与查询参数（query-param）语法一致。
