Verified CloudControl context provider works: import * as cxschema from '@aws-cdk/cloud-assembly-schema';
import { Toolkit } from '@aws-cdk/toolkit-lib';
import * as cdk from 'aws-cdk-lib';
(async () => {
const toolkit = new Toolkit({ sdkConfig: { profile: 'sandbox' } });
const cx = await toolkit.fromAssemblyBuilder(async () => {
const app = new cdk.App();
const stack = new cdk.Stack(app, 'Stack', { env: { region: 'us-east-1', account: 'ACCOUNT-ID' } });
const responses = cdk.ContextProvider.getValue(stack, {
provider: cxschema.ContextProvider.CC_API_PROVIDER,
props: {
typeName: 'AWS::EC2::PrefixList',
propertyMatch: {
PrefixListName: 'com.amazonaws.global.cloudfront.origin-facing',
},
propertiesToReturn: ['PrefixListId'],
},
dummyValue: [{ PrefixListId: 'pl-xxxxxxxx' }],
}).value;
new cdk.CfnOutput(stack, 'PrefixListId', {
value: responses[0].PrefixListId,
});
return app.synth();
});
const cxSnap = await toolkit.synth(cx);
const assembly = await cxSnap.produce();
const template = assembly.getStackByName('Stack').template;
const { Outputs } = template;
console.log(JSON.stringify({ Outputs }, undefined, 2));
})().catch(console.error); $ yarn ts-node --prefer-ts-exts cc-api-test.ts
