CADT API 包含了一组OpenAPI接口，为了快速了解集成API后如何快速创建ECS，下面通过一个集成demo cadt 命令行工具帮助大家快速体验效果。
操作前提
请确保您已安装了Python，并且Python版本在3.6以上。
安装Git，如未安装，请参考安装Git。
创建阿里云账号，并生成RAM 账号AK/SK。
操作步骤
快速安装CADT命令行工具。
git clone https://code.aliyun.com/best-practice/cadt-cli.git cd cadt-cli sudo pip3 install -e .工具初始化。
说明需要输入阿里云账号AK/SK，注意确保账号具有ECS管理权限，VPC创建权限，以及CADT管理权限，详情参见权限说明。
% cadt --help 2023-07-15 10:23:41 : [Errno 2] No such file or directory: './.cadt.config' To use cadt command line tools you need to specified aliyun access key and secret.

Commands: apply 创建应用，校验，询价，并输出结果，用户输入yes后执行部署 batch-apply 批量创建应用，校验，询价，执行部署 create-app 基于CADT上官方模板或私有模板创建新的应用 delete-app 删除应用 deploy 部署应用并创建资源 download-app-image 获取应用的架构图 get-app 获取指定应用的基本信息、校验结果、计费结果、部署结果 get-template 获取模板图片及架构图相关信息 list-apps 该接口提供当前用户下所有应用的列表。其中可选参数keyword定义应用名中包含的关键字 list-templates 获取模板列表，包括模板名称、架构图地址、架构图序列化文件地址等 release 该接口释放应用的资源 step-apply 按顺序创建应用，校验，询价，执行部署 validate 对应用下的资源输入的合法性进行校验，异步执行，校验结果调用GetApplication获取 valuate 对应用下的资源进行询价，通过GetApplication获取询价结果 valuate-template 基于CADT上官方模板或私有模板进行询价（可选）定义ECS模型YAML文件。

template_id ：UWWDJZTL4UYBVFPQ
CADT官方提供的ECS创建模板，该模型配置VPC，虚拟交换机，安全组，以及ECS，模型中的资源属性支持变量，具体参见单产品模板示例-ECS。
instances：网络相关参数
variables：模板变量传参
configuration：部署优化选项（默认）
output：输出
保存配置文件，例如保存为ecs.yaml。
执行部署。
直接指定模板ID和地域进行部署。
cadt apply -t UWWDJZTL4UYBVFPQ -a cn-hangzhou或者指定配置文件部署：
cadt apply -f ecs.yaml输出结果。
