Overview

etcd is a distributed, highly available key/value datastore for state within a cluster. etcd is used by Kubernetes and OpenShift to maintain configuration and other state.

etcd is designed for large scale distributed systems, that will never tolerate split brain operation and are willing to sacrifice availability to achieve this.

etcd can be used as a consistent key-value store for configuration management, service discovery and coordinating distributed work.
