前言

最近开始接触Google的Kubernetes（简称k8s,由于字母k与字母s之间省略8个字母），这篇文章记录一下我的初体验。

环境准备

我是使用Vagrant来快速构建基本的虚拟机环境，有人说干嘛不用Docker，哈哈，也是可以的，但是怎么感觉有点『骑马找马』的感觉，如果你使用Docker，记得开放30001口，我们后面会用到。

Vagrant安装非常简单，下载地址：

https://www.vagrantup.com/downloads.html

选择你对应的平台，会自带安装VirtualBox。

vagrant我选用了bento/centos-7.1这个镜像。

Mac用户创建一个文件夹并进入初始化它。

cd ~mkdir k8scd k8svagrant init bento/centos-7.1

将配置修改Vagrantfile：

# -*- mode: ruby -*-# vi: set ft=ruby :# All Vagrant configuration is done below. The "2" in Vagrant.configure# configures the configuration version (we support older styles for# backwards compatibility). Please don't change it unless you know what# you're doing.Vagrant.configure(2) do |config|  # The most common configuration options are documented and commented below.  # For a complete reference, please see the online documentation at  # https://docs.vagrantup.com.  # Every Vagrant development environment requires a box. You can search for  # boxes at https://atlas.hashicorp.com/search.  config.vm.box = "bento/centos-7.1"  # Disable automatic box update checking. If you disable this, then  # boxes will only be checked for updates when the user runs  # `vagrant box outdated`. This is not recommended.  # config.vm.box_check_update = false  # Create a forwarded port mapping which allows access to a specific port  # within the machine from a port on the host machine. In the example below,  # accessing "localhost:8080" will access port 80 on the guest machine.  # config.vm.network "forwarded_port", guest: 80, host: 8080  # Create a private network, which allows host-only access to the machine  # using a specific IP.  config.vm.network "private_network", ip: "192.168.8.8"  # Create a public network, which generally matched to bridged network.  # Bridged networks make the machine appear as another physical device on  # your network.  # config.vm.network "public_network"  # Share an additional folder to the guest VM. The first argument is  # the path on the host to the actual folder. The second argument is  # the path on the guest to mount the folder. And the optional third  # argument is a set of non-required options.  config.vm.synced_folder ".", "/vagrant_data"  # Provider-specific configuration so you can fine-tune various  # backing providers for Vagrant. These expose provider-specific options.  # Example for VirtualBox:  #   # config.vm.provider "virtualbox" do |vb|  ## Display the VirtualBox GUI when booting the machine  # vb.gui = true  #   ## Customize the amount of memory on the VM:  # vb.memory = "1024"  # end  #   # View the documentation for the d you are using for more  # information on available options.  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies  # such as FTP and Heroku are also available. See the documentation at  # https://docs.vagrantup.com/v2/push/atlas.html for more information.  # config.push.define "atlas" do |push|  # push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"  # end  # Enable provisioning with a shell script. Additional provisioners such as  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the  # documentation for more information about their specific syntax and use.  # config.vm.provision "shell", inline: vagrant up启动环境。一下是我的项目文件夹结构：我们对应创建好这几个文件，为了避免新手错误的书写格式导致启动失败带来挫败感，我把我的配置文件上传一份到GitHub:https://github.com/cnBruceHong/learn-k8s运行：

vagrant ssh

进入虚拟机。# 安装K8s## 关闭防火墙systemctl disable firewalldsystemctl stop firewalld## 安装etcd和k8s

sudo yum install etcd kubernetes vim

## 修改配置文件

sudo vim /etc/sysconfig/docker

修改里面对应的内容为：

OPTIONS='--selinux-enabled=false --insecure-registry gcr.io'

还要修改：

sudo vim /etc/kubernetes/apiserver

修改里面的内容为：

KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota"

启动所有服务：

sudo systemctl start etcd docker kube-apiserver kube-controller-manager kube-scheduler kubelet kube-proxy

然后顺序运行：

cd /vagrant_data/
kubectl create -f redis-master-controller.yaml
kubectl create -f redis-master-service.yaml
kubectl create -f redis-slave-controller.yaml
kubectl create -f redis-slave-service.yaml
kubectl create -f frontend-controller.yaml
kubectl create -f frontend-service.yaml

然后在宿主机上浏览器访问：http://192.168.8.8:30001就可以看到界面了。你可以通过kubectl get pods来查看pods，里面的要running才算成功哦！~# 最后里面会有一些你不懂的名词，没关系，你可以自主学习这些名词。这篇文章关键是：## ヾ(｡｀Д´｡)你成功搭起来了K8s，成就感暴满有木有？#k8s#
