1. What is ETCD service? ETCD is a health/value pair storage System with HTTP protocol, which is a distributed and functional hierarchy configuration system, which can be used to build service discovery system. Distributed, consistent kv storage system for shared configuration and service discovery. It is easy to deploy, install, and use, providing reliable data persistence features. It is secure and the do

This is a creation in Article, where the information may have evolved or changed. The ETCD team has just been excited to announce the newest member--etcd 3.2.0 in the Etcd 3.x series. New features and features such as agent improvements, enhanced backend concurrency, distributed coordination services, lighter go clients, and JWT authentication are emerging in thi

Preface The previous article talked about some common cluster operations in ETCD, which mainly covered some common problems that might be encountered, after all, the God (Operational dimension) perspective always sees the problem and then recovers. For a cluster, it is common to process crashes, physical machine downtime, data migration backups, capacity reduction, and so on. The rest of the operation is nothing more than some common problem-handling

1. Single ETCD node (for test development)Before I have been developing a test that has been used for a ETCD node, then the Start command has been directly hitting a ETCD (I have added the bin directory of the ETCD installation directory to the PATH environment variable), and then the boot information shows

This is a creation in Article, where the information may have evolved or changed. "Editor's note" This article compares three service discovery tools for zookeeper, ETCD, and Consul, and explores the best solution for service discovery, for informational purposes only. If you use a predefined port, the more services you have, the greater the likelihood of a conflict, after all, it is impossible to have two services listening on the same port. Managin

First, Introduction"A highly-available key value store for shared configuration and service discovery."ETCD is a distributed service system developed by CoreOS, and the raft protocol is adopted internally as the consistency algorithm. As a highly available configuration sharing, service discovery key-value storage System, ETCD has the following features:1) Simple: Simple installation configuration, and the

ETCD is a highly available key-value storage system that is used primarily for shared configuration and service discovery. ETCD is developed and maintained by CoreOS and is inspired by ZooKeeper and Doozer, which is written in the go language and handles log replication through the raft consistency algorithm to ensure strong consistency. Raft is a new consistency algorithm from Stanford, suitable for the lo
