custom-resource: installLatestAwsSdk could timeout in China regions

[pahud]

Describe the bug

aws-cdk/packages/aws-cdk-lib/custom-resources/lib/aws-custom-resource/aws-custom-resource.ts

Line 351 in 3f6401c

readonly installLatestAwsSdk?: boolean;

This function triggers a straight npm install which generally would timeout in China regions.

aws-cdk/packages/@aws-cdk/custom-resource-handlers/lib/custom-resources/aws-custom-resource-handler/aws-sdk-v3-handler.ts

Line 24 in 671b760

function installLatestSdk(packageName: string): void {

This is not a bug we just need some workaround for it.

Expected Behavior

installLatestSdk would not timeout

Current Behavior

would timeout

Reproduction Steps

set installLatestAwsSdk to true in custom resource

Workaround

Set installLatestAwsSdk: false or the feature flag @aws-cdk/customresources:installLatestAwsSdkDefault to false.

See: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.custom_resources.AwsCustomResource.html#installlatestawssdk

Possible Solution

I guess China users might need to use npm proxy or alternative mirrors to work it around.

If you are not using AwsCustomResource to directly call APIs without your custom code, you can use NodejsFunction to bundle the specific SDK within your lambda.

I've confirmed this issue doesn't exist in cn-north-1 and cn-northwest-1 anymore with the following code.

import {
  App, Stack,
  aws_eks as eks,
  aws_ec2 as ec2,
  aws_iam as iam,
} from 'aws-cdk-lib';

import { KubectlV29Layer } from '@aws-cdk/lambda-layer-kubectl-v29';

const app = new App();

const stack = new Stack(app, 'my-test-stack4');

const mastersRole = new iam.Role(stack, 'AdminRole', {
  assumedBy: new iam.AccountRootPrincipal(),
});

const vpc = new ec2.Vpc(stack, 'Vpc', { natGateways: 1 });

new eks.Cluster(stack, 'Cluster', {
  vpc,
  mastersRole,
  version: eks.KubernetesVersion.V1_29,
  kubectlLayer: new KubectlV29Layer(stack, 'KubectlLayer'),
  defaultCapacity: 2,
});

@aws-cdk/customresources:installLatestAwsSdkDefault is now default to false since 2.60.0.
