容器是發展趨勢，所以是時候從虛擬機中脫離出來，投入到容器化的懷抱中了。
曾經試過安裝k8s，都沒有成功，各種亂七八糟的報錯，於是一拖再拖，這次總算發現一個可以快速部署的工具，終於安裝成功了。
這個k8s快速部署工具就是kubekit
github地址是
https://github.com/Orientsoft/kubekit
直接按照以上這個地址的步驟部署也可以。
接下來我說一下具體的部署說明：
大體步驟是在關閉防火牆的Centos7.3上，下載解壓kubekit安裝包以及package壓縮包，將package移入kubekit解壓出來的文件夾中，同時對package中的sh文件添加可執行權限。進入kubekit文件夾，執行./kubekit init 服務器ip地址。正常情況下，安裝成功的話會提示9000端口已監聽。這個就是k8s的web界面。
系統環境：
Centos7.3
kubekit下載地址
https://kubekit.orientsoft.cn/kubekit-linux64-0.3.tar.gz
package下載地址
https://kubekit.orientsoft.cn/package-1.7.2.tar.gz
直接貼出我的命令執行歷史，可以參考一下。加粗部分要額外注意

在瀏覽器中訪問。可以看到k8s的界面了
以上是在我自己的電腦上測試的，但是換一台電腦好像不行，現在還在找原因，如果找到了，我再補充進來
12月10日補充：
關閉防火牆並且不修改默認的selinux，同時只在一個命令窗口執行？反正沒報錯
