现在网络上流传很多Kubernetes的部署和搭建的文档，其中比较出名就是Kubernetes The Hard Way

（https://github.com/kelseyhightower/kubernetes-the-hard-way），还有基于这个翻译和衍生的版本follow-me-install-kubernetes-cluster

（https://github.com/opsnull/follow-me-install-kubernetes-cluster），这两篇文章带我走过了Kubernetes的搭建的童年，我第一搭建成功就是抄袭的张俊的follow-me-install-kubernetes-cluster，然后随着新版的发展，越来越多的配置参数存在各种各样的问题，最大的问题是在CNI产生后，两篇文章的配置参数和系统默认或者CNI配置参数有稍微的冲突导致很多人在利用CNI做网络方案的时候会出现很多问题，这篇文章目的第一是向两位前辈致敬，第二是共享下在Flanneld和Calico部署过程中遇到挫折和问题。

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

User authentication system

Your task is now to create a user authentication system.

This document will guide you through all the features and implication of such system, so that you don't have to search them yourself.

We will focus on web/browser-technologies, however similar concept can be widely applied. This guide, is a work in progress, feel free to comment and provide feedbacks.
