How to Update/Upgrade Ubuntu on AWS Instance?

Introduction

In this guide, we will demonstrate how to update and upgrade an Ubuntu instance on AWS using Pulumi with TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. By leveraging Pulumi, we can automate the process of updating and upgrading an Ubuntu instance on AWS, ensuring that our infrastructure is always up-to-date and secure.

The key services involved in this solution are:

• AWS EC2: Amazon Elastic Compute Cloud (EC2) provides scalable computing capacity in the AWS cloud. We will use EC2 to launch and manage our Ubuntu instance.
• Pulumi: Pulumi is an open-source infrastructure as code tool that enables you to create, deploy, and manage cloud resources using programming languages like TypeScript.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

1. Install Pulumi CLI if you haven’t already.
2. Create a new Pulumi project using TypeScript.
3. Configure your AWS credentials to allow Pulumi to manage your AWS resources.

Step 2: Define AWS EC2 Instance

1. Import the necessary Pulumi and AWS SDK packages.
2. Define the AWS EC2 instance resource with the desired Ubuntu AMI, instance type, and key pair.
3. Add user data to the EC2 instance to run the update and upgrade commands on startup.

Step 3: Deploy the Infrastructure

1. Run pulumi up to preview and deploy the changes.
2. Verify that the EC2 instance is created and the update and upgrade commands are executed successfully.

Key Points

• Pulumi allows you to define and manage cloud resources using familiar programming languages like TypeScript.
• AWS EC2 provides scalable computing capacity in the AWS cloud, making it easy to launch and manage instances.
• User data can be used to run scripts on instance startup, allowing us to automate the update and upgrade process for our Ubuntu instance.
• Pulumi’s pulumi up command is used to preview and deploy changes to our infrastructure.

Conclusion

By following this guide, you have learned how to update and upgrade an Ubuntu instance on AWS using Pulumi with TypeScript. This approach leverages the power of Pulumi to automate infrastructure management, ensuring that your instances are always up-to-date and secure. With Pulumi, you can easily define, deploy, and manage cloud resources using familiar programming languages, making infrastructure as code more accessible and efficient.

Full Code Example

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

const ubuntuAmi = aws.ec2.getAmi({
    filters: [{
        name: "name",
        values: ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"],
    }],
    mostRecent: true,
    owners: ["099720109477"], // Canonical
});

const instance = new aws.ec2.Instance("ubuntuInstance", {
    instanceType: "t2.micro",
    ami: ubuntuAmi.then(ami => ami.id),
    userData: `#!/bin/bash
sudo apt-get update -y
sudo apt-get upgrade -y
`,
    tags: {
        Name: "UbuntuInstance",
    },
});

export const publicIp = instance.publicIp;
