How Do I Create an AWS EC2 Internet Gateway?

Introduction

This guide provides a comprehensive walkthrough for creating an Internet Gateway for an AWS EC2 instance using Pulumi. An Internet Gateway is an essential VPC component that facilitates communication between your VPC instances and the internet. It is designed for high availability and redundancy, ensuring seamless connectivity.

Key Points

• We will create a VPC (Virtual Private Cloud).
• We will create an Internet Gateway.
• We will attach the Internet Gateway to the VPC.

Step-by-Step Process

1. Create a VPC: Begin by setting up a Virtual Private Cloud (VPC). This serves as the network boundary for your AWS resources.
2. Create an Internet Gateway: Next, establish an Internet Gateway. This component allows your VPC to communicate with the internet.
3. Attach the Internet Gateway to the VPC: Finally, link the Internet Gateway to your VPC to enable internet access for instances within the VPC.

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

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

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

// Export the IDs of the VPC and Internet Gateway
export const vpcId = vpc.id;
export const internetGatewayId = internetGateway.id;

Summary

In this guide, we successfully created a VPC and an Internet Gateway using Pulumi. By attaching the Internet Gateway to the VPC, we enabled instances within the VPC to communicate with the internet. The process concluded with exporting the IDs of the created VPC and Internet Gateway, which can be used for future configurations or references.
