How do I associate key pairs with auto-scaling groups on AWS?

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

// Create an EC2 Key Pair
const keyPair = new aws.ec2.KeyPair("myKeyPair", {
    keyName: "my-key-pair",
    publicKey: "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA7..." // Replace with your actual public key
});

// Create a Launch Configuration using the Key Pair
const launchConfiguration = new aws.ec2.LaunchConfiguration("myLaunchConfig", {
    imageId: "ami-0c55b159cbfafe1f0", // Replace with a valid AMI ID
    instanceType: "t2.micro",
    keyName: keyPair.keyName,
    securityGroups: ["sg-0a1234567890abcdef"], // Replace with your security group ID
    userData: `#!/bin/bash
echo "Hello, World!" > index.html
nohup python -m SimpleHTTPServer 80 &`
});

// Create an Auto-Scaling Group with the Launch Configuration
const autoScalingGroup = new aws.autoscaling.Group("myAutoScalingGroup", {
    launchConfiguration: launchConfiguration.id,
    minSize: 1,
    maxSize: 3,
    desiredCapacity: 2,
    vpcZoneIdentifiers: ["subnet-0bb1c79de3EXAMPLE"], // Replace with your subnet ID
    tags: [{
        key: "Name",
        value: "my-auto-scaling-group",
        propagateAtLaunch: true,
    }],
});

// Export the name of the Key Pair and Auto-Scaling Group
export const keyPairName = keyPair.keyName;
export const autoScalingGroupName = autoScalingGroup.name;
