容器是发展趋势，所以是时候从虚拟机中脱离出来，投入到容器化的怀抱中了。
曾经试过安装k8s，都没有成功，各种乱七八糟的报错，于是一拖再拖，这次总算发现一个可以快速部署的工具，终于安装成功了。
这个k8s快速部署工具就是kubekit
github地址是
https://github.com/Orientsoft/kubekit
直接按照以上这个地址的步骤部署也可以。
接下来我说一下具体的部署说明：
大体步骤是在关闭防火墙的Centos7.3上，下载解压kubekit安装包以及package压缩包，将package移入kubekit解压出来的文件夹中，同时对package中的sh文件添加可执行权限。进入kubekit文件夹，执行./kubekit init 服务器ip地址。正常情况下，安装成功的话会提示9000端口已监听。这个就是k8s的web界面。
系统环境：
Centos7.3
kubekit下载地址
https://kubekit.orientsoft.cn/kubekit-linux64-0.3.tar.gz
package下载地址
https://kubekit.orientsoft.cn/package-1.7.2.tar.gz
直接贴出我的命令执行历史，可以参考一下。加粗部分要额外注意

在浏览器中访问。可以看到k8s的界面了
以上是在我自己的电脑上测试的，但是换一台电脑好像不行，现在还在找原因，如果找到了，我再补充进来
12月10日补充：
关闭防火墙并且不修改默认的selinux，同时只在一个命令窗口执行？反正没报错
