L3 construct helping with PrivateLink-powered VPC Interface Endpoints for AWS Services.

🚧   Project Stability

This construct is still versioned with v0 major version and breaking changes might be introduced if necessary (without a major version bump), though we aim to keep the API as stable as possible (even within v0 development). We aim to publish v1.0.0 soon and after that breaking changes will be introduced via major version bumps.

Getting Started

Endpoint open to whole isolated subnet

import { AwsInterfaceEndpoints } from '@alma-cdk/aws-interface-endpoints';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

const vpc = new ec2.Vpc();

new AwsInterfaceEndpoints(this, 'EcrInterfaceEndpoint', {
  vpc,
  services: [
    { id: 'EcrDocker', ec2.InterfaceVpcEndpointAwsService.ECR_DOCKER },
  ],
});

Session Manager connection endpoints

import { AwsInterfaceEndpoints } from '@alma-cdk/aws-interface-endpoints';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

const vpc = new ec2.Vpc();

new AwsInterfaceEndpoints(this, 'SessionManagerInterfaceEndpoint', {
  vpc,
  services: AwsInterfaceEndpoints.SessionManagerConnect,
});

Explictly opened endpoints

1. In your VPC creation stack

import { AwsInterfaceEndpoints } from '@alma-cdk/aws-interface-endpoints';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

const vpc = new ec2.Vpc();

new AwsInterfaceEndpoints(this, 'EcrInterfaceEndpoint', {
  vpc,
  open: false,
  services: [
    { id: 'EcrDocker', ec2.InterfaceVpcEndpointAwsService.ECR_DOCKER },
  ],
});

1. In some other stack (maybe on a completely different CDK application):

import { AwsInterfaceEndpoints } from '@alma-cdk/aws-interface-endpoints';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

define instance: ec2.Instance;

const endpoints = AwsInterfaceEndpoints.fromAttributes(this, 'EcrInterfaceEndpoint', {
  services: [
    { id: 'EcrDocker', ec2.InterfaceVpcEndpointAwsService.ECR_DOCKER },
  ],
});

endpoints.allowDefaultPromFrom(instance);
