用Json Template在Azure上创建Cisco CSR路由器

Azure的ARM模式可以通过Json的模板创建VM。本文以Cisco的CSR的image为例，介绍如何用Json的创建VM。

一、Cisco CSR的Image

首先把Cisco CSR的image复制到一个存储账户中：

https://xxxx.blob.core.chinacloudapi.cn/image/CSR_3_16_4aS_CCO.vhd

创建VM的vhd文件也需要在这个存储账户中。

二、获得Json模板

在Github上找到From user image create VM的Json模板：

https://github.com/Azure/azure-quickstart-templates/tree/master/101-vm-from-user-image

把azuredeploy.json文件保存到本地：

https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-vm-from-user-image/azuredeploy.json

为d:from_image.json文件。由于Global Azure的Disk目前已经prefer使用Management Disk了，Github上的template已经改成MD的template。

下面是采用普通存储账户的Json Template：

          }
        }
      }
    }
  ]
}

三、通过模板创建Cisco CSR虚拟机

1. 登录Azure China的Portal

2. 在New中搜索template

如上图所示，点击Template Deployment。这里需要注意的是，目前必须是英文版本才可以使用这个功能。

3. 导入template

把刚刚的Json Template上传。

4. 填写相应的Parameters

根据实际值，填写相应的参数。需要注意的是Resource Group和Storage Account都要和image所在的Storage Account相同。

4. Legal Terms

把Legal Terms相应的内容填写完整：

然后点击create，创建VM。

四、登录创建的Cisco CSR router
