Azure Blueprint 初体验

接下来我们来试着用Blueprint部署一台虚拟机，整个过程其实和用ARM Template部署时差不太多，说白了其实也是在Blueprint里嵌套了ARM Template，使用Blueprint好处就是可以有版本的迭代，版本的变更也都可以有记录，同时还可以配合一些Azure Policy一起用，比如在Blueprint里定义创建一个资源组，然后针对资源组定义好一组Azure Policy，限制在这个资源组内可以做的操作，然后再部署虚拟机，这样就是一整套的操作了

首先创建一个蓝图定义，在这个蓝图里我们会创建一台Windows的虚拟机

首先先添加一个资源组，这个资源组可以是已经存在的，也可以是需要新建的

之后添加下一个步骤，在资源组内添加一套ARM Template脚本，在脚本中定义的就是创建Windows虚拟机的过程

Template内容大致如下：

可以提前设置好一些参数的值，这样在分配蓝图时就不需要再指定这些值了
