etcd kubernetes

service discovery system is widely used by kubernetes and other systemsIs it easier for him than for zookeeper to be more efficient in the face of smaller clusters? And his programming language go itself is a multithreaded programming language, indeed there is a lot of attraction (although I do not understand the go language, but in learning Docker is also a glimpse of the style)In raft, any time a server can play one of the following roles:Leader: H

I. Introduction:Kubernetes is an open source container management tool, based on the Go language implementation, lightweight and portable applications, you can put kubernetes cluster on the Linux host deployment, management and expansion of the Docker container application on multiple hosts.Two. Architecture: 1. The kubernetes consists of the following components:

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

cluster can communicate in the same virtual network.Fannel first connects to Etcd, uses ETCD to manage assignable IP address segment resources, monitors the actual address of each pod in Etcd, and builds a POD node routing table in memory that encapsulates the packets sent to it by DOCKER0. The connection of the physical network is used to deliver the data to th

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

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

How to build a Kubernetes (k8s) Environment The official version of k8s is updated too quickly. Many articles on the Internet are outdated and many tools and interfaces have changed. the official website does not have a good understanding. Here we only record the process of setting up the k8s environment and will not talk about many k8s concepts. Therefore, we recommend that you first understand various concepts and then build the environment, then, i
