Creating a Simple Web Server on AWS

In this example, we use JavaScript to create a simple web server on AWS using EC2.

This code creates the necessary security group, deploys a very simple web server for example purposes, and then creates the instance, before exporting the IP and Hostname.

Pulumi can be used on any resource on AWS, Azure, GCP, Kubernetes, and OpenStack, covering serverless, containers, and infrastructure.

const aws = require("@pulumi/aws");

let size = "t2.micro";
let ami  = "ami-7172b611"
    
 // create a new security group for port 80
let group = new aws.ec2.SecurityGroup("web-secgrp", { 
    ingress: [
        { protocol: "tcp", fromPort: 22, 
            toPort: 22, cidrBlocks: ["0.0.0.0/0"] },
        { protocol: "tcp", fromPort: 80, 
            toPort: 80, cidrBlocks: ["0.0.0.0/0"] },
    ],
});
    
// create a simple web server
let userData = 
    `#!/bin/bash
    echo "Hello, World!" > index.html
    nohup python -m SimpleHTTPServer 80 &`;
    
let server = new aws.ec2.Instance("web-server-www", {
    tags: { "Name": "web-server-www" },
    instanceType: size,
    securityGroups: [ group.name ], 
    ami: ami,
    userData: userData              
});
    
exports.publicIp = server.publicIp;
exports.publicHostName = server.publicDns;
