How Can I Configure Pulumi to Deploy an AWS Environment With Native Code Configuration in TypeScript

Introduction

In this guide, we will configure Pulumi to deploy an AWS environment using native code configuration in TypeScript. The key services involved include setting up an AWS VPC, subnets, an internet gateway, and a security group. We will also create an EC2 instance within this environment.

Step-by-Step Explanation

Step 1: Install Pulumi and AWS CLI

Ensure you have Pulumi and AWS CLI installed on your machine. You can install Pulumi by following the instructions here. AWS CLI installation instructions can be found here.

Step 2: Create a New Pulumi Project

1. Create a new directory for your project and navigate into it:

   mkdir pulumi-aws-ts
   cd pulumi-aws-ts
   

2. Initialize a new Pulumi project:

   pulumi new aws-typescript
   

Step 3: Configure AWS Credentials

Ensure your AWS CLI is configured with the necessary credentials:

aws configure

Step 4: Define the AWS Environment

1. Open the index.ts file in your project directory.
2. Add the following code to set up the VPC, subnets, internet gateway, and security group:

   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",
   });
   
   // Create subnets
   const subnet = new aws.ec2.Subnet("my-subnet", {
       vpcId: vpc.id,
       cidrBlock: "10.0.1.0/24",
       availabilityZone: "us-west-2a",
   });
   
   // Create an Internet Gateway
   const igw = new aws.ec2.InternetGateway("my-igw", {
       vpcId: vpc.id,
   });
   
   // Create a Security Group
   const securityGroup = new aws.ec2.SecurityGroup("my-sg", {
       vpcId: vpc.id,
       ingress: [{
           protocol: "tcp",
           fromPort: 22,
           toPort: 22,
           cidrBlocks: ["0.0.0.0/0"],
       }],
       egress: [{
           protocol: "-1",
           fromPort: 0,
           toPort: 0,
           cidrBlocks: ["0.0.0.0/0"],
       }],
   });
   
   // Create an EC2 Instance
   const instance = new aws.ec2.Instance("my-instance", {
       instanceType: "t2.micro",
       vpcSecurityGroupIds: [securityGroup.id],
       ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2 AMI
       subnetId: subnet.id,
   });
   

Step 5: Deploy the Stack

1. Run pulumi up to preview and deploy the changes:

   pulumi up
   

2. Confirm the deployment by typing yes when prompted.

Summary

In this guide, we walked through the steps to configure Pulumi to deploy an AWS environment using TypeScript. We set up a VPC, subnets, an internet gateway, a security group, and an EC2 instance. By following these steps, you can easily manage and deploy AWS resources using Pulumi’s infrastructure as code approach.

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",
});

// Create subnets
const subnet = new aws.ec2.Subnet("my-subnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
});

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

// Create a Security Group
const securityGroup = new aws.ec2.SecurityGroup("my-sg", {
    vpcId: vpc.id,
    ingress: [{
        protocol: "tcp",
        fromPort: 22,
        toPort: 22,
        cidrBlocks: ["0.0.0.0/0"],
    }],
    egress: [{
        protocol: "-1",
        fromPort: 0,
        toPort: 0,
        cidrBlocks: ["0.0.0.0/0"],
    }],
});

// Create an EC2 Instance
const instance = new aws.ec2.Instance("my-instance", {
    instanceType: "t2.micro",
    vpcSecurityGroupIds: [securityGroup.id],
    ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2 AMI
    subnetId: subnet.id,
});
