[NestJS] AWS에서 동적으로 서브도메인 생성하기

AWS SDK 설치

npm install aws-sdk

Controller 생성

import { Controller, Post, Body } from '@nestjs/common';
import { AwsService } from './aws.service';

@Controller('subdomain')
export class SubdomainController {
    constructor(private readonly awsService: AwsService) {}

    @Post()
    async createSubdomain(@Body() body: { subdomain: string }): Promise<{ subdomain: string }> {
        const subdomainName = body.subdomain;

        // AWS SDK를 사용하여 서브도메인 생성
        const createdSubdomain = await this.awsService.createSubdomain(subdomainName);

        return { subdomain: createdSubdomain };
    }
}

Service 생성

import { Injectable } from '@nestjs/common';
import * as AWS from 'aws-sdk';

@Injectable()
export class AwsService {
    private readonly route53: AWS.Route53;

    constructor() {
        AWS.config.update({ region: 'YOUR_AWS_REGION' });
        this.route53 = new AWS.Route53();
    }

    async createSubdomain(subdomainName: string): Promise<string> {
        const hostedZoneId = 'YOUR_HOSTED_ZONE_ID'; // Route 53에서 찾을 수 있는 호스팅 존 ID
        const domainName = 'formflet.io'; // 도메인 이름

        const changeBatch = {
            Changes: [
                {
                    Action: 'UPSERT',
                    ResourceRecordSet: {
                        Name: `${subdomainName}.${domainName}`,
                        Type: 'CNAME',
                        TTL: 300,
                        ResourceRecords: [
                            {
                                Value: 'YOUR_TARGET_VALUE', // 실제로는 이 부분을 원하는 대상으로 설정해야 합니다.
                            },
                        ],
                    },
                },
            ],
        };

        const params = {
            ChangeBatch: changeBatch,
            HostedZoneId: hostedZoneId,
        };

        try {
            await this.route53.changeResourceRecordSets(params).promise();
            return `${subdomainName}.${domainName}`;
        } catch (error) {
            console.error(error);
            throw new Error('Error creating subdomain');
        }
    }
}

• 'YOUR_AWS_REGION', 'YOUR_HOSTED_ZONE_ID', 'YOUR_TARGET_VALUE'는 실제 값으로 설정.

module 수정

import { Module } from '@nestjs/common';
import { SubdomainController } from './subdomain.controller';
import { AwsService } from './aws.service';

@Module({
    controllers: [SubdomainController],
    providers: [AwsService],
})
export class SubdomainModule {}

• app.module.ts 에서 SubdomainModule import.

Copy code
import { Module } from '@nestjs/common';
import { SubdomainModule } from './subdomain/subdomain.module';

@Module({
    imports: [SubdomainModule],
})
export class AppModule {}
