etcd vs zookeeper

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

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

have any effect;Swarm manager needs to know which swarm node, which requires "service discovery" (with registration to find), swarm service discovery methods are many, here are two main experiments, that is, through the Docker hub token and ETCD;(1) As mentioned in the previous article that Docker-machine,docker-machine is integrated with Docker swarm, the Docker hub token is made by applying a token to the Docker hub token via Swarm, Then add all of

Refer to my previous article (Click here) to introduce a key issue in the etcd cluster environment: Which of the three etcd nodes should be accessed by clustering )??? (1) Any of the three read operations can be performed, even if it is not a leader (2) For write operations, it seems that only the leader can be connected to write data. I have a cluster composed of three nodes (127.0.0.1: 4001, 127.0.0.1:

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
