• "ZStackTemplateFormatVersion": "2018-06-18"

  定义模板版本。

• "Description": "Creates Vxlan VPC network. This template creates a VPC network. Make sure that the public network and management network are working as expected. Note that the VXLAN VTEP CIDR is required."

  定义对模板的解释说明。

• "Parameters": { }

  定义模板的参数列表。

  本例中定义了以下参数：

  • 路由器镜像URL
  • 云主机镜像URL
  • 镜像服务器
  • 管理网络
  • 公有网络
  • 区域
  • 集群
  • VTEP CIDR
  • VNI、起始VNI、结束VNI
  • 起始IP、结束IP、子网掩码、网关
• "Resources": { }

  定义该模板将要创建的资源。

  本例中声明将要创建以下资源：

  • 添加一个路由器镜像
  • 添加一个云主机镜像
  • 创建一个路由器规格
  • 创建一个VPC路由器
  • 创建VXLAN网络池
  • 指定VNI范围
  • 创建一个二层VXLAN网络
  • 创建一个VPC网络
  • 挂载VPC网络到云主机
  • 配置VPC网络的IP范围
  • 挂载二层网络到集群
  • 创建一个计算规格
  • 创建一个云主机

  这里声明的资源属性可以引用"Parameters": { }中定义的参数。
• "Outputs": { }

  定义资源创建完成后，通过资源栈输出资源属性等有用信息。

• 区域：自动显示当前区域
• 名称：设置资源栈名称
• 简介：可选项，可留空不填
• 超时设置：设置创建资源栈的超时时限，超时将失败，默认为60分钟
• 失败回滚：设置创建失败是否清理已创建的资源，默认开启
• 创建方式：选择创建资源栈方式，本章节以创建LNMP为例。支持以下三种方式：
  • 资源栈模板：使用系统模板或自定义模板创建资源栈
    说明: 如何创建自定义模板，请参考资源栈模板章节。
  • 上传文件：使用已定义的UTF8编码格式模板文件创建资源栈
    说明: 关于模板语法的详细介绍，请参考资源栈模板语法章节。
  • 自定义文本：在文件编辑器中编辑模板创建资源栈
    说明: 关于模板语法的详细介绍，请参考资源栈模板语法章节。
