(docker-discover), Some back-end services (WHOAMI) and the last consumer (Ubuntu/curl). The registration and Discovery component works as a device and application container, so the registration or discovery code on the backend or consumer container is not embedded. They only listen to ports or connect to other local ports. Service Registration-ETCD Before anything is registered, we need some place to track registration entries (for example, the IP an

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

1. Single etcd node (for test and Development) I used to develop and test an etcd node, and started the command to directly create an etcd (I have added the bin directory of the etcd installation directory TO THE PATH environment variable ), then, the startup information shows that the

systems support stale reads in case of node loss) before resuming communication between nodes and synchronizing data.ZooKeeper, one of the oldest in such frameworks, is written by Java. Java is great in many ways, but it is still a bit heavy for this type of work, and because of its complexity and yearning for new things, we give up choosing it the first time.This paper compares ETCD and Consul from protocol and application layer, and finally gives t

The root partition is designed to be read-only to ensure data consistency and update availability CPU, IO and other resources isolation, naturally to sacrifice the container (Container), CoreOS very wise use Docker as a container manager to build an

This is a creation in Article, where the information may have evolved or changed. As early as November 2013, in the raft paper can only be downloaded to the draft version on the Internet, I have written a blog on its brief analysis. Over the past 4 years, various raft agreements have been extensively explained, and raft has indeed been widely used. One of the most well-known applications is ETCD. Etcd the

to the 127.0.0.1: 4001 node in the cluster. At the beginning, the leader of the cluster is 127.0.0.1: 4001. However, over time, the leader may change to 127.0.0.1: 4002 or 127.0.0.1: 4003, I found a conclusion: as long as the leader is 127.0.0.1: 4001, the service can be successfully registered (successfully written to the cluster), as long as the leader is not 127.0.0.1: 4001, the registration will fail! The read configuration items in the loop will remain valid and will not expire as the lead
