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" } } - 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。import * as ros from '@alicloud/ros-cdk-core'; import * as ecs from '@alicloud/ros-cdk-ecs'; import * as ROS from '@alicloud/ros-cdk-ros'; export class DemoStack extends ros.Stack { constructor(scope: ros.Construct, id: string, props?: ros.StackProps) { super(scope, id, props); new ros.RosInfo(this, ros.RosInfo.description, "This is the simple ros cdk app example."); // The code that defines your stack goes here const nginxDefaultPort = new ros.RosParameter(this, 'NginxDefaultPort', { type: ros.RosParameterType.STRING, }); const ecsInstanceType = new ros.RosParameter(this, 'EcsInstanceType', { type: ros.RosParameterType.STRING, }); const systemDiskCategory = new ros.RosParameter(this, 'SystemDiskCategory', { type: ros.RosParameterType.STRING, }); const vpc = new ecs.Vpc(this, 'vpc-from-ros-cdk', { vpcName: 'test-ros-cdk-vpc', cidrBlock: '10.0.0.0/8', description: 'This is ros cdk test' }); const vsw = new ecs.VSwitch(this, `vsw-from-ros-cdk`, { vpcId: vpc.attrVpcId, // zoneId: ros.Fn.select(0, ros.Fn.getAzs(ros.Fn.ref('ALIYUN::Region'))), zoneId: 'cn-beijing-h', vSwitchName: 'test-ros-cdk-vsw', cidrBlock: '10.0.0.0/16', }); const sg = new ecs.SecurityGroup(this, 'ros-cdk-test-sg',{ vpcId: vpc.attrVpcId, securityGroupName: 'test-ros-cdk-sg', securityGroupIngress: [{'portRange':'22/22','nicType':'intranet','ipProtocol':'tcp','sourceCidrIp':'0.0.0.0/0'}, {'portRange':'80/80','nicType':'intranet','ipProtocol':'tcp','sourceCidrIp':'0.0.0.0/0'}] }); const ecsWaitConditionHandle = new ROS.WaitConditionHandle(this,'RosWaitConditionHandle',{ count: 1 }) const ecsWaitCondition = new ROS.WaitCondition(this,'RosWaitCondition',{ timeout: 300, handle: ros.Fn.ref('RosWaitConditionHandle'), count: 1 }) let NginxDefaultPort = nginxDefaultPort.valueAsString const ecsGroups = new ecs.InstanceGroup(this,'ros-cdk-test-ecs',{ vpcId: vpc.attrVpcId, vSwitchId: vsw.attrVSwitchId, imageId: 'centos_7', maxAmount: 1, securityGroupId: sg.attrSecurityGroupId, instanceType: ecsInstanceType.valueAsString, systemDiskCategory: systemDiskCategory.valueAsString, instanceName: 'test-ros-cdk-ecs', userData: ros.Fn.replace({ NOTIFY: ecsWaitConditionHandle.attrCurlCli }, `#!/bin/bash\nyum install -y nginx\nsed -i \'s/listen 80;/listen ${NginxDefaultPort};/\' /etc/nginx/nginx.conf \nsystemctl restart nginx\n NOTIFY`), }); } } - 执行以下命令，生成模板文件。
ros-cdk synth --json执行命令后，输出以下内容：
{ "Description": "This is the simple ros cdk app example.", "Metadata": { "ALIYUN::ROS::Interface": { "TemplateTags": [ "Create by ROS CDK" ] } }, "ROSTemplateFormatVersion": "2015-09-01", "Parameters": { "NginxDefaultPort": { "Type": "String" }, "EcsInstanceType": { "Type": "String" }, "SystemDiskCategory": { "Type": "String" } }, "Resources": { "vpc-from-ros-cdk": { "Type": "ALIYUN::ECS::VPC", "Properties": { "CidrBlock": "10.0.0.0/8", "Description": "This is ros cdk test", "EnableIpv6": false, "VpcName": "test-ros-cdk-vpc" } }, "vsw-from-ros-cdk": { "Type": "ALIYUN::ECS::VSwitch", "Properties": { "CidrBlock": "10.0.0.0/16", "VpcId": { "Fn::GetAtt": [ "vpc-from-ros-cdk", "VpcId" ] }, "ZoneId": "cn-beijing-h", "VSwitchName": "test-ros-cdk-vsw" } }, "ros-cdk-test-sg": { "Type": "ALIYUN::ECS::SecurityGroup", "Properties": { "SecurityGroupIngress": [ { "PortRange": "22/22", "SourceCidrIp": "0.0.0.0/0", "IpProtocol": "tcp", "NicType": "intranet" }, { "PortRange": "80/80", "SourceCidrIp": "0.0.0.0/0", "IpProtocol": "tcp", "NicType": "intranet" } ], "SecurityGroupName": "test-ros-cdk-sg", "VpcId": { "Fn::GetAtt": [ "vpc-from-ros-cdk", "VpcId" ] } } }, "RosWaitConditionHandle": { "Type": "ALIYUN::ROS::WaitConditionHandle", "Properties": { "Count": 1, "Mode": "Full" } }, "RosWaitCondition": { "Type": "ALIYUN::ROS::WaitCondition", "Properties": { "Handle": { "Ref": "RosWaitConditionHandle" }, "Timeout": 300, "Count": 1 } }, "ros-cdk-test-ecs": { "Type": "ALIYUN::ECS::InstanceGroup", "Properties": { "ImageId": "centos_7", "InstanceType": { "Ref": "EcsInstanceType" }, "MaxAmount": 1, "AllocatePublicIP": true, "AutoRenew": "False", "AutoRenewPeriod": 1, "InstanceChargeType": "PostPaid", "InstanceName": "test-ros-cdk-ecs", "InternetChargeType": "PayByTraffic", "InternetMaxBandwidthIn": 200, "InternetMaxBandwidthOut": 1, "IoOptimized": "optimized", "Period": 1, "PeriodUnit": "Month", "SecurityGroupId": { "Fn::GetAtt": [ "ros-cdk-test-sg", "SecurityGroupId" ] }, "SystemDiskCategory": { "Ref": "SystemDiskCategory" }, "UserData": { "Fn::Replace": [ { "NOTIFY": { "Fn::GetAtt": [ "RosWaitConditionHandle", "CurlCli" ] } }, { "Fn::Join": [ "", [ "#!/bin/bash\nyum install -y nginx\nsed -i 's/listen 80;/listen ", { "Ref": "NginxDefaultPort" }, ";/' /etc/nginx/nginx.conf \nsystemctl restart nginx\n NOTIFY" ] ] } ] }, "VpcId": { "Fn::GetAtt": [ "vpc-from-ros-cdk", "VpcId" ] }, "VSwitchId": { "Fn::GetAtt": [ "vsw-from-ros-cdk", "VSwitchId" ] } } } } } - 执行以下命令，创建资源栈。
ros-cdk deploy --parameters EcsInstanceType=ecs.c6e.large --parameters NginxDefaultPort=8080 --parameters SystemDiskCategory=cloud_essd --sync=true执行命令后，输出以下内容：

- 执行以下命令：
ros-cdk destroy --sync=true - 根据界面提示，确认删除。
