Exports: MyVpc

Required construct packages: @aws-cdk/aws-ec2

The custom construct MyVpc wraps a common configuration for creating a vpc by just giving it some basic requirements, like vpc CIDR block and number of public subnets you need in the vpc.

Usage

import * as cdk from '@aws-cdk/core';
import { MyVpc } from './vpc';

export class ServerlessInfrastructureCdkStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props: StackProps) {
    super(scope, id);

    const { vpc } = new MyVpc(this, 'MyAwesomeVpc', {
      vpcCidr: '10.0.0.0/16',
      publicSubnetsNo: 2,
      maxAzs: 2,
      privateSubnetsNo: 1,
    });
  }
}

This will create a vpc with 2 AZs (Availabilaty zones), 2 public subnets and 1 subnet for each AZ.
