<!--
 ReplicaSet is the next-generation Replication Controller.
-->

ReplicaSet 是下一代副本控制器。

<!--more--> 

<!--
ReplicaSet, like ReplicationController, ensures that a specified number of pods replicas are running at one time. ReplicaSet supports the new set-based selector requirements as described in the labels user guide, whereas a Replication Controller only supports equality-based selector requirements.
-->

ReplicaSet 就像 ReplicationController 那样，确保一次运行指定数量的 Pod 副本。ReplicaSet 支持新的基于集合的选择器需求（在标签的用户指南中有相关描述），而副本控制器只支持基于等值的选择器需求。
