This is a CDK construct that retrieves the private IP address of an Interface VPC Endpoint:

npm install cdk-vpc-endpoint-with-private-ip

You can create an interface VPC endpoint and retrive its private IP addresses using the VpcEndpointWithPrivateIp construct.

The ec2.InterfaceVpcEndpointProps can be passed to the construct to configure the interface VPC endpoint.

import { InterfaceVpcEndpointWithPrivateIp } from 'cdk-vpc-endpoint-with-private-ip';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

declare const vpc: ec2.IVpc;

const endpoint = new InterfaceVpcEndpointWithPrivateIp(this, 'Endpoint', {
  vpc,
  service: ec2.InterfaceVpcEndpointAwsService.S3,
});

const privateIps = endpoint.privateIps;

Note: privateIps is an array of CDK Tokens, and the actual IP addresses are not determined until the stack is deployed.
