How do I set up a dedicated GitLab Runner instance on AWS EC2?

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

// Define the configuration for the EC2 instance
const size = "t2.micro"; // Instance size
const ami = aws.ec2.getAmi({
    filters: [{ name: "name", values: ["amzn2-ami-hvm-*-x86_64-gp2"] }],
    owners: ["137112412989"], // Amazon
    mostRecent: true,
}).then(ami => ami.id);

// Create a security group allowing SSH and HTTP/HTTPS access
const securityGroup = new aws.ec2.SecurityGroup("gitlab-runner-sg", {
    description: "Allow SSH and HTTP/HTTPS",
    ingress: [
        { protocol: "tcp", fromPort: 22, toPort: 22, cidrBlocks: ["0.0.0.0/0"] }, // SSH
        { protocol: "tcp", fromPort: 80, toPort: 80, cidrBlocks: ["0.0.0.0/0"] }, // HTTP
        { protocol: "tcp", fromPort: 443, toPort: 443, cidrBlocks: ["0.0.0.0/0"] }, // HTTPS
    ],
    egress: [
        { protocol: "-1", fromPort: 0, toPort: 0, cidrBlocks: ["0.0.0.0/0"] }, // Allow all outbound traffic
    ],
});

// Create an EC2 key pair to access the instance
const keyPair = new aws.ec2.KeyPair("gitlab-runner-keypair", {
    publicKey: "<your-ssh-public-key>",
});

// Create the EC2 instance
const server = new aws.ec2.Instance("gitlab-runner-instance", {
    instanceType: size,
    ami: ami,
    keyName: keyPair.keyName,
    securityGroups: [securityGroup.name],
    userData: `#!/bin/bash
                sudo yum update -y
                sudo yum install -y git curl
                curl -L --output /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64
                sudo chmod +x /usr/local/bin/gitlab-runner
                sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash
                sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
                sudo gitlab-runner start`,
    tags: {
        Name: "gitlab-runner-instance",
    },
});

// Export the public IP of the server
export const publicIp = server.publicIp;
export const publicDns = server.publicDns;
