步骤 1：下载 AWS CloudFormation 模板

您可以使用 AWS CloudFormation 模板来配置和预配置产品组合和产品。模板是 JSON 或 YAML 格式的文本文件，描述了您希望预配置的资源。有关更多信息，请参阅 https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-formats.html 用户指南 中的AWS CloudFormation模板格式。您可以使用 AWS CloudFormation 编辑器或自己选择的文本编辑器创建和保存模板。在本教程中，我们提供了一个简单模板来帮助您入门。此模板会启动为 SSH 访问而配置的单个 Linux 实例。

模板下载

为本教程提供的示例模板，development-environment.template，可在以下网址获得：https://awsdocs.s3.amazonaws.com/servicecatalog/development-environment.template。

模板概述

示例模板的文本如下所示：

  "Description" : "AWS Service Catalog sample template. Creates an Amazon EC2 instance 
                    running the Amazon Linux AMI. The AMI is chosen based on the region 
                    in which the stack is run. This example creates an EC2 security 
                    group for the instance to give you SSH access. **WARNING** This 
                    template creates an Amazon EC2 instance. You will be billed for the
