intro to kubernetes

[TOC]DescriptionThere is no detailed explanation of the Kubernetes's service exposure and Traefik's principles. The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-

This is a creation in Article, where the information may have evolved or changed. Kris Nova, of Microsoft, shares lessons on over-engineering from she experience contributing to Kubernetes Kops. In hers spare time, she runs a Kubernetes special Interest Group bringing Kubernetes to AWS, all and working on Microsoft Acs. She ' s writing a book called Cloud Native

The role of Kubernetes Scheduler is to bind controller manager to a new pod according to a specific scheduling algorithm and scheduling policy to a suitable node in the cluster, and to write the binding information to the ETCD.I.

Brief Description:Using the Rke tool, on the 192.168.3.161 machine, create a kubernetes cluster with two nodes (192.168.3.162 and 192.168.3.163). Rke automatically creates KUBE_CONFIG_CLUSTER.YML configuration files in the/home/user directory.On another server (192.168.3.160), run the Rancher Server 2.0 container. After running, use the https://192.168.3.160 address to access Rancher Server 2.0 preview. (Note: No longer the previous 8080 port)In the R

previous Chapters Kubernetes All operations we are using command line tools kubectl completed. To provide a richer user experience, Kubernetes also developed a WEB-based Dashboard that enables users to deploy containerized applications with Kubernetes Dashboard, monitor the status of applications, perform troubleshooting tasks, and manage

First, prefaceKubernetes is the Google Open Source container cluster management system, based on Docker to build a container scheduling service, providing resource scheduling, balanced disaster recovery, service registration, dynamic expansion capacity and other functional suites, currently the latest version is 0.6.2. This article describes how to build Kubernetes platform based on Centos7.0, before it is formally introduced, it is necessary to under

How to obtain a Kubernetes image in China I. background As we all know, due to domestic network reasons, when building a Kubernetes environment, we often encounter situations where necessary images cannot be found. After all, it is not a good way to pick up junk in DockerHub. This article will teach you how to build your own image repository in DockerHub. Requirement: You have a GitHub account and a DockerH

Use Rancher's RKE to quickly deploy a Kubernetes Cluster Brief description: This article involves three Ubuntu machines, one RKE deployment machine (192.168.3.161), and two Kubernetes cluster machines (3.162 and 3.163 ). First on a Windows machine, download the rke_linux-amd64 from github, rename it rke, edit the cluster. the yml cluster deployment file uses the pscp Command provided by putty to upload the

With the popularity of micro-service architectures and the trend of cloud-native, containerized microservices have become the best product of continuous delivery and have become the kubernetes best ecosystem for operation and maintenance containers. Practice out of knowledge, since kubernetes the study, wrote a series of articles, in order to be able to learn from each other, to find knowledge of the loopho

The current skaffold version is v0.4 and has not yet been released, and is not recommended for use in production environments;Skaffold is used for developer rapid deployment programs to Kubernetes,Skaffold provides dev, run two modes , and Skaffold requires a skaffold configuration file that defines Skaffold workflow ；The Skaffold workflow defines three main stages : Build, Push, Deploy;First, BuildDuring the build phase, Skaffold uses the dockerfile

As early as half a year ago, the company began to implement the container deployment scheme Appos, although the publishing interface is too geek, very obscure, but carefully studied really feel very powerful, after the implementation of the container, computing resources (CPU, memory) utilization can be greatly improved, reduce the number of servers, thereby saving technical costs. Coincidentally, a number of friends in the start-up companies are also recently trying to do micro-services, contai
