在 AWS CDK 中为多个堆栈创建可预测的堆栈名称

Question

在由 multiple stacks that I would like to deploy to multiple environments 组成的 AWS CDK 应用程序中执行 npx cdk synth 时如何获取 "nice" 堆栈名称？

#!/usr/bin/env node
import * as cdk from '@aws-cdk/core';
import * as s3 from '@aws-cdk/aws-s3';
import * as lambda from '@aws-cdk/aws-lambda';


class PersistenceStack extends cdk.Stack {
    public readonly bucket: s3.Bucket;
    constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
        super(scope, id, props);
        this.bucket = new s3.Bucket(this, 'bucket');
    }
}


interface ApplicationStackProps extends cdk.StackProps {
    bucket: s3.Bucket;
}


class ApplicationStack extends cdk.Stack {
    constructor(scope: cdk.Construct, id: string, props: ApplicationStackProps) {
        super(scope, id, props);
        const myLambda = new lambda.Function(this, 'my-lambda', {
            runtime: lambda.Runtime.NODEJS_12_X,
            code: new lambda.AssetCode('my-lambda'),
            handler: 'index.handler'
        });
        props.bucket.grantReadWrite(myLambda);
    }
}


class MyApp extends cdk.Construct {

    constructor(scope: cdk.Construct, id: string, props: cdk.StackProps) {
        super(scope, id);

        const persistenceStack = new PersistenceStack(this, 'persistence-stack', {
            ...props,
            description: 'persistence stack',
            stackName: `${id}-persistence-stack`,
        });

        const applicationStack = new ApplicationStack(this, 'application-stack', {
            ...props,
            description: 'application stack',
            stackName: `${id}-application-stack`,
            bucket: persistenceStack.bucket,
        });
        applicationStack.addDependency(persistenceStack);
    }
}


const app = new cdk.App();

new MyApp(app, `test`, { env: { account: '111111111111', region: 'eu-west-1' } });
new MyApp(app, `prod`, { env: { account: '222222222222', region: 'eu-west-1' } });

我面临的问题是这会生成类似于以下内容的输出：

Successfully synthesized to [...]/my-app/cdk.out
Supply a stack id (prodpersistencestackFE36DF49, testpersistencestack6C35C777, prodapplicationstackA0A96586, testapplicationstackE19450AB) to display its template.

我希望看到的是 "nice" 堆栈名称（因为我在调用构造函数时指定了 stackName 属性）：

Successfully synthesized to [...]/my-app/cdk.out
Supply a stack id (prodpersistencestack, testpersistencestack, prodapplicationstack, testapplicationstack) to display its template.

动机：我需要 "nice"（或至少是可预测的）堆栈名称来为我们的 CI/CD 管道提供下一步，以便构建服务器可以部署 CDK 应用程序。

AWS CDK 版本：1.21.1

这 AWS CDK issue 解决了这个问题。在其回复中指出，堆栈 ID 是设计使然的（因为一个人可以在多个环境中具有相同的堆栈名称）。

为了将堆栈名称用作部署参数，可以实现对 cdk.out/manifest.json 文件的反向查找，因为那里提供了堆栈 ID 和堆栈名称之间的映射信息。以下是如何使用 jq:

实现此类查找的摘录

# get stack name from somewhere, e.g. test-persistence-stack, prod-persistence-stack, test-application-stack or prod-application-stack from the question above
stackName=    

# extract stack id from ./cdk.out/manifest.json
stackId=$(jq -r --arg stackName "$stackName" \
   '.artifacts
   | to_entries[]
   | select(.value.properties.stackName == $stackName)
   | .key
   ' \
   < "./cdk.out/manifest.json" \
   )

# call cdk deploy with stack id as parameter
npx cdk deploy \
  --app cdk.out \
  --require-approval never \
  "$stackId"
