OpenStack 平台中的 etcd 是一个分布式键值存储系统，用于存储 OpenStack 组件的配置信息。在 OpenStack 中， etcd 通常用于存储一些关键的配置信息，如网络、存储和计算等方面的配置信息。这些 信息可以被分布式地存储在多个 etcd 节点上，以提高可用性和容错性。
etcd 可以被用作 OpenStack 中的共享存储，所有的 OpenStack 组件都可以通过 etcd 存储和获取配置 信息。这样， etcd 可以提供一个中心化的配置管理系统，使得 OpenStack 组件可以更加方便地进行配置 和管理。同时， etcd 还可以提供一些高级功能，如分布式锁和事务处理等，以支持更加复杂的应用场 景。
