我怎么能得到漂亮的堆栈名称时执行npx cdk synth
在一个AWSCDK应用程序,是由多个堆栈,我想部署到多个环境?
#!/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,这会产生类似的输出:
Successfully synthesized to [...]/my-app/cdk.out
Supply a stack id (prodpersistencestackFE36DF49, testpersistencestack6C35C777, prodapplicationstackA0A96586, testapplicationstackE19450AB) to display its template.
我期望看到的是“漂亮”的堆栈名称(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:我需要漂亮的(或者至少是可预测的)堆栈名称来输入下一步我们的CI/CD管道,以便构建服务器可以部署CDK应用程序。
AWSCDK版本
这个AWSCDK问题解决了这个问题。在其响应中,它指出堆栈ID在设计上是这样的(因为在多个环境中可以具有相同的堆栈名称)。
为了使用堆栈名称作为部署参数,可以实现cdk. out/清单.json
文件的反向查找,因为堆栈id和堆栈名称之间的映射信息在那里可用。下面是如何使用jq实现这种查找的摘录:
# 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"
