本文以TypeScript语言为例，为您介绍如何使用ROS CDK部署Nginx服务。
步骤一：初始化工程
执行以下命令，创建工程目录并初始化工程。
mkdir demo
cd demo
ros-cdk init --language=typescript --generate-only=true步骤二：配置阿里云凭证信息
执行以下命令，配置阿里云凭证信息。
ros-cdk config根据界面提示输入配置信息。
ros-cdk config endpoint(optional, default:https://ros.aliyuncs.com): defaultRegionId(optional, default:cn-hangzhou):cn-beijing [1] AK [2] StsToken [3] RamRoleArn [4] EcsRamRole [0] CANCEL Authenticate mode [1...4 / 0]: 1 accessKeyId:************************ accessKeySecret:****************************** ✅ Your cdk configuration has been saved successfully!
步骤三：安装依赖
修改
package.json文件，添加ECS依赖包（ros-cdk-ecs）。{ "name": "demo", "version": "0.1.0", "bin": { "demo": "bin/demo.js" }, "scripts": { "build": "tsc", "test": "jest" }, "devDependencies": { "@types/jest": "^25.2.1", "@types/node": "10.17.5", "typescript": "^3.9.7", "jest": "^25.5.0", "ts-jest": "^25.3.1", "ts-node": "^8.1.0", "babel-jest": "^26.6.3", "@babel/core": "^7.12.9", "@babel/preset-env": "7.12.7", "@babel/preset-typescript": "^7.12.7", "@alicloud/ros-cdk-assert": "^1.0.0" }, "dependencies": { "@alicloud/ros-cdk-core": "^1.0.5", "@alicloud/ros-cdk-ecs": "^1.0.3", "@alicloud/ros-cdk-ros": "1.0.0" } }执行以下命令，安装依赖。
npm install
步骤四：管理资源栈
修改
lib/demo-stack.ts文件，创建ECS实例并安装Nginx服务。下列提供多语言的示例代码供您参考。
TypeScript示例
