How Do I Code the Creation of an AWS EC2 VPC in TypeScript

Introduction

In this solution, we will create an AWS EC2 VPC using Pulumi in TypeScript. A Virtual Private Cloud (VPC) is a virtual network dedicated to your AWS account. It is logically isolated from other virtual networks in the AWS Cloud. You can launch your AWS resources, such as Amazon EC2 instances, into your VPC. This solution will involve creating a VPC, subnets, an internet gateway, and route tables.

Step-by-Step Explanation

Step 1: Create a New Pulumi Project

First, create a new Pulumi project. You can do this by running pulumi new typescript in your terminal. This will set up a new Pulumi project with TypeScript as the language.

Step 2: Install AWS Pulumi Package

Next, install the AWS Pulumi package by running npm install @pulumi/aws in your project directory. This package contains the necessary resources and data sources to interact with AWS services.

Step 3: Create a VPC

In your index.ts file, import the necessary modules from the Pulumi AWS package and create a new VPC. You can specify the CIDR block for the VPC.

Step 4: Create Subnets

Create public and private subnets within the VPC. You can specify the CIDR blocks for each subnet.

Step 5: Create an Internet Gateway

Create an internet gateway and attach it to the VPC. This will allow resources in the public subnet to communicate with the internet.

Step 6: Create Route Tables

Create route tables for the public and private subnets. Associate the public route table with the internet gateway and the public subnet. Associate the private route table with the private subnet.

Step 7: Export VPC Information

Finally, export the VPC ID and subnet IDs as stack outputs. This will allow you to reference these values in other parts of your Pulumi project.

Key Points

• A VPC is a virtual network dedicated to your AWS account.
• Subnets are subdivisions of a VPC and can be either public or private.
• An internet gateway allows resources in the public subnet to communicate with the internet.
• Route tables control the routing of traffic within the VPC.
• Pulumi allows you to define and manage your cloud infrastructure using code.

Conclusion

In this solution, we created an AWS EC2 VPC using Pulumi in TypeScript. We covered the creation of a VPC, subnets, an internet gateway, and route tables. By using Pulumi, we can define and manage our cloud infrastructure as code, making it easier to version control and automate our deployments.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create a VPC
const vpc = new aws.ec2.Vpc("my-vpc", {
    cidrBlock: "10.0.0.0/16",
    enableDnsHostnames: true,
    enableDnsSupport: true,
    tags: { Name: "my-vpc" },
});

// Create a public subnet
const publicSubnet = new aws.ec2.Subnet("public-subnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
    mapPublicIpOnLaunch: true,
    tags: { Name: "public-subnet" },
});

// Create a private subnet
const privateSubnet = new aws.ec2.Subnet("private-subnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.2.0/24",
    availabilityZone: "us-west-2a",
    tags: { Name: "private-subnet" },
});

// Create an Internet Gateway
const igw = new aws.ec2.InternetGateway("my-igw", {
    vpcId: vpc.id,
    tags: { Name: "my-igw" },
});

// Create a route table for the public subnet
const publicRouteTable = new aws.ec2.RouteTable("public-route-table", {
    vpcId: vpc.id,
    routes: [
        { cidrBlock: "0.0.0.0/0", gatewayId: igw.id },
    ],
    tags: { Name: "public-route-table" },
});

// Associate the route table with the public subnet
new aws.ec2.RouteTableAssociation("public-route-table-association", {
    subnetId: publicSubnet.id,
    routeTableId: publicRouteTable.id,
});

// Create a route table for the private subnet
const privateRouteTable = new aws.ec2.RouteTable("private-route-table", {
    vpcId: vpc.id,
    tags: { Name: "private-route-table" },
});

// Export the VPC ID and subnet IDs
export const vpcId = vpc.id;
export const publicSubnetId = publicSubnet.id;
export const privateSubnetId = privateSubnet.id;
