CDK Vpc

Utility constructs for tagging subnets or creating a cheaper vpc.

• Cheaper Vpc
• Tagging subnets

Install

TypeScript

npm install @pepperize/cdk-vpc

or

yarn add @pepperize/cdk-vpc

Python

pip install pepperize.cdk-vpc

C# / .Net

dotnet add package Pepperize.CDK.Vpc

Java

<dependency>
  <groupId>com.pepperize</groupId>
  <artifactId>cdk-vpc</artifactId>
  <version>${cdkVpc.version}</version>
</dependency>

Getting Started

1. Create a new CDK TypeScript App project with projen

   mkdir my-project
   cd my-project
   git init -b main
   npx projen new awscdk-app-ts

2. Add @pepperize/cdk-vpc to your dependencies in .projenrc.js

   const project = new awscdk.AwsCdkTypeScriptApp({
     //...
     deps: ["@pepperize/cdk-vpc"],
   });

3. Install the dependency

   npx projen

Usage

Create a cheaper Vpc

Use this as a cheaper drop-in replacement to create a vpc with 2 AvailabilityZones and a t3.nano NatInstance.

import { App, Stack } from "aws-cdk-lib";
import { CheapVpc } from "@pepperize/cdk-vpc";

const app = new App();
const stack = new Stack(app, "MyCheapVpcStack");

new CheapVpc(stack, "MyCheapVpc");

Tag your imported subnets

Subnets imported by Vpc.fromLookup wouldn't be tagged by Tags.of automatically. To tag them (or any other imported vpc resource) use:

import { CheapVpc } from "@pepperize/cdk-vpc";
import * as ec2 from "aws-cdk-lib/aws-ec2";

const app = new App();
const stack = new Stack(app, "VpcStack");
const vpc = ec2.Vpc.fromLookup(stack, "VpcLookup", {
  vpcId: "vpc-1234567890",
  region: env.region,
});

new CreateTags(vpcStack, "TagPrivateSubnets", {
  resourceIds: vpc.privateSubnets.map((subnet) => {
    return subnet.subnetId;
  }),
  tags: [
    {
      key: "kubernetes.io/role/internal-elb",
      value: "1",
    },
  ],
});
