# Zookeeper ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. Visit the [Official Site](https://zookeeper.apache.org/). ### Usage This is a standalone Zookeeper deployment suitable for development and testing purposes. As such, there is not much to configure. Once deployed, you may inspect Zookeeper information with the `zk-cli` command. If deployment was successful, you'll see something similar to this: ``` $ zk-cli Connecting to localhost:2181 Welcome to ZooKeeper! JLine support is enabled WATCHER:: WatchedEvent state:SyncConnected type:None path:null [zk: localhost:2181(CONNECTED) 0] ```
