+Kube-scheduler selects an optimal node to run newly created or not yet
+scheduled (unscheduled) pods. Since containers in pods - and pods themselves -
+can have different requirements, the scheduler filters out any nodes that

+Kube-scheduler 选择一个最佳节点来运行新创建的或尚未调度（unscheduled）的 Pod。
+由于 Pod 中的容器和 Pod 本身可能有不同的要求，调度程序会过滤掉任何不满足 Pod 特定调度需求的节点。
+或者，API 允许你在创建 Pod 时为它指定一个节点，但这并不常见，并且仅在特殊情况下才会这样做。
