etcdctl cluster-health ``` 这行代码用来检查etcd集群的健康状态,确保etcd集群正常运行。 4. 写入数据到etcd ``` etcdctl put key value ``` 这行代码用来向etcd中写入数据,key表示键值对的键,value表示键值对的值。 5. 从etcd中读取数据 ```
etcd在键的组织上采用了层次化的空间结构(类似于文件系统中目录的概念),用户指定的键可以为单独的名字,如:testkey,此时实际上放在根目录/下面,也可以为指定目录结构,如/cluster1/node2/testkey,则将创建相应的目录结构。 3.1 键操作 set 指定某个键的值。例如:etcdctlput/testdir/testkey"Helloworld" get 获取...
静态发现: 预先已知etcd集群中有哪些节点,在启动时通过–initial-cluster参数直接指定好etcd的各个节点地址。 etcd动态发现:通过已有的etcd集群作为数据交互点,然后在扩展新的集群时实现通过已有集群进行服务发现的机制。比如官方提供的:discovery.etcd.io ...
