error: failed to auto-generate value for "roleName"

[schnipseljagd]

What happened?

I've been trying to use CrossAccountZoneDelegationRecord and adapted the example slightly to work with the pulumi cdk.

pulumi up

created the following error:

error: failed to auto-generate value for "roleName". Prefix: "CustomCrossAccountZoneDelegationCustomResourceProviderRoleED64687B-" is too large to fix max length constraint of 64. Please provide a value for "roleName"

roleName is always autogenerated by the cdk lib here so I can't provide it myself.

Expected Behavior

Probably Pulumi should truncate the name and make sure it's still unique.

Steps to reproduce

use this snippet and maybe replace my-domain.de and account: '999999999' with real values:

export class DnsStack extends pulumicdk.Stack {
  hostedZoneName: pulumi.Output<string>;

  constructor(id: string, options?: pulumicdk.StackOptions) {
    super(id, { ...options });

    const subZone = new route53.PublicHostedZone(this, 'SubZone', {
      zoneName: 'dns-test.my-domain.de',
    })

    // import the delegation role by constructing the roleArn
    const delegationRoleArn = Stack.of(this).formatArn({
      region: '', // IAM is global in each partition
      service: 'iam',
      account: '999999999',
      resource: 'role',
      resourceName: 'MyDelegationRole',
    })
    const delegationRole = iam.Role.fromRoleArn(
      this,
      'DelegationRole',
      delegationRoleArn,
    )

    // create the record
    new route53.CrossAccountZoneDelegationRecord(this, 'DelegateToParent', {
      delegatedZone: subZone,
      parentHostedZoneName: 'my-domain.de', // or you can use parentHostedZoneId
      delegationRole,
    })

    this.hostedZoneName = this.asOutput(subZone.zoneName);

    this.synth();
  }
}

Hey @schnipseljagd. Thanks for bringing up this issue! I agree that we should truncate.

[lukehoban]

This is similar to https://github.com/pulumi/pulumi-cdk/issues/62. This issue hits the error in AWS Native, the other hits it in AWS Classic. I think in both cases, we might actually want to change the behaviour of autonaming in those providers (and all providers) to not hard fail here.

Good catch that the underlying problem is from AWS native! I'll move this over to the bridge. We can set up some logic to truncate over-long autonames.
