typescript - AWS Lambda CDK 不生成 SNS 主题和订阅

Question

我正在使用 Typescript 和 CDK 在 AWS 中生成新的 SNS 主题和订阅。除了运行编译（npm run build）之外，是否还需要在代码中执行其他步骤才能在 AWS 中生成这些对象？

以下是一些代码片段：

import * as sns from '@aws-cdk/aws-sns';
import * as subs from '@aws-cdk/aws-sns-subscriptions';

let lambda = new Function(this, 'Function', {
  runtime: Runtime.NODEJS_10_X,
  handler: "src/handler.handler",
  code: Code.fromAsset("function"),
  role: lambdaRole,
  logRetention: RetentionDays.TWO_WEEKS,
  logRetentionRole: lambdaRole,
  timeout: Duration.seconds(10),
  environment,
  vpc,
  vpcSubnets: {
    subnets: subnets
  },
  securityGroups: [
    new SecurityGroup(this, "SG", {
      vpc,
      allowAllOutbound: true,
      description: StackConfiguration.name + "-sg",
      securityGroupName: StackConfiguration.name + "-sg",
    })
  ],
  functionName: StackConfiguration.name,
  allowAllOutbound: true,
  description: `Handler for ${StackConfiguration.name} with version ${StackConfiguration.version}`
});    

const isProd = StackConfiguration.environmentKey === 'production';

const key = new Key(this, "CustomKey");
key.grantEncryptDecrypt(lambda);
const topic = new sns.Topic(this, "outbound-claim-events-lambda-topic", {
  masterKey: key
});

if(isProd) {
  topic.addSubscription(new subs.EmailSubscription('xxxxxxxxx'));
} else {
  topic.addSubscription(new subs.EmailSubscription('xxxxxxxxx'));
}
topic.grantPublish(lambda)

您需要CDK deploy在将 AWS CLI 配置到要将组件部署到的 AWS 账户时运行。
