昨天折腾了一天在openshift上diy支持spring-boot的环境，于是想终结一下也是给需要的朋友一个参考。
这篇文章中主要适用在openshift上部署了application后，在本地用eclipse继续开发的case，如果已经有一个现成的proj，只是需要部署上去的话，请参考本人的git 上的代码（https://github.com/RxCAI/openshift-diy-spring-boot-sample）这个sample原作者是kolorobot，因为我在开始尝试的时候发现它的配置中的maven mirror无法下载造成了部署错误，所以修改commit了他的代码。
下面进入正题：
一 如何在openshift上DIY一个支持spring-boot的环境
为什么要DIY？最重要的原因在于，目前openshift上现成的模版maven的版本太低，而spring-boot要求Maven 3.2+ or Gradle 1.12+。 所以要想部署spring-boot project到openshift上去，就一定要DIY。另外，现成的模版JDK还停留在7，所以如果需要8，也需要DIY。说完了why，接下来就是how了 ->
首先当然是安装openshift的rhcThe OpenShift Client tools, known asrhc。
具体步骤参考：https://developers.openshift.com/en/managing-client-tools.html
它的环境要求是Ruby 1.8.7 or + 以及 git
本人的系统是mac os x 10.8.5系统自带ruby 1.8.7及 git 1.8.5.2。
确认环境符合要求后，用命令行安装rhc
sudo gem install rhc
如果有问题的话官方建议run
sudo gem update 就是更新一下它的依赖库什么的。
但是，事情从来不是那么顺利，所以童话故事都是骗人的。。。
我遇到了和这位老兄一模一样的问题https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1190896 虽然他是Linux的都是我的问题和他的几乎一模一样。
