How Can I Code to Establish an AWS EC2 Instance?

Introduction

In this solution, we will establish an AWS EC2 instance using Pulumi in TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. AWS EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud, making it easier for developers to build and deploy applications.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, we need to set up a new Pulumi project. This involves installing Pulumi CLI, creating a new project, and configuring AWS credentials.

Step 2: Define AWS Provider

Next, we will define the AWS provider in our Pulumi program. This will allow Pulumi to interact with AWS services.

Step 3: Create a Security Group

We will create a security group to control the inbound and outbound traffic for our EC2 instance.

Step 4: Launch an EC2 Instance

Finally, we will launch an EC2 instance using the defined security group and other necessary configurations.

Key Points

• Pulumi allows you to define cloud infrastructure using familiar programming languages.
• AWS EC2 provides scalable compute capacity in the cloud.
• Security groups are used to control traffic to and from AWS resources.
• Pulumi CLI is required to manage and deploy Pulumi projects.

Conclusion

By following the steps outlined above, you can easily establish an AWS EC2 instance using Pulumi in TypeScript. This approach leverages the power of Infrastructure as Code to automate and manage cloud resources efficiently.

Full Code Example

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

// Create a new security group
const securityGroup = new aws.ec2.SecurityGroup("web-sg", {
    description: "Enable HTTP access",
    ingress: [
        {
            protocol: "tcp",
            fromPort: 80,
            toPort: 80,
            cidrBlocks: ["0.0.0.0/0"],
        },
    ],
});

// Create a new EC2 instance
const server = new aws.ec2.Instance("web-server", {
    instanceType: "t2.micro",
    ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2 AMI
    securityGroups: [securityGroup.name],
});

// Export the instance ID and public IP
export const instanceId = server.id;
export const publicIp = server.publicIp;
