  2. Building an AWS Native Auto Scaling Launch Configuration with Pulumi

How do I build an AWS native autoscaling launch configuration with Pulumi?

In this guide, we will create an AWS Auto Scaling Launch Configuration using Pulumi in TypeScript. An Auto Scaling Launch Configuration specifies the instance configuration for an Auto Scaling group, ensuring that all instances launched by the group have consistent settings.

Key Points:

  • Define an AWS Launch Configuration with necessary instance details.
  • Use the aws-native Pulumi provider to manage the resources.
  • Ensure all instances launched by the Auto Scaling group have consistent settings.
import * as pulumi from "@pulumi/pulumi";
import * as awsNative from "@pulumi/aws-native";

// Create a Launch Configuration for the Auto Scaling group
const launchConfiguration = new awsNative.autoscaling.LaunchConfiguration("myLaunchConfiguration", {
    imageId: "ami-0c55b159cbfafe1f0",  // Replace with a valid AMI ID
    instanceType: "t2.micro",  // Instance type
    securityGroups: ["sg-0a1b2c3d4e5f67890"],  // Replace with a valid Security Group ID
    keyName: "my-key-pair",  // Replace with a valid Key Pair name
    userData: pulumi.interpolate`#!/bin/bash
echo "Hello, World!" > /var/www/html/index.html`,  // User data script to run on instance launch
    blockDeviceMappings: [{
        deviceName: "/dev/sda1",
        ebs: {
            volumeSize: 8,  // Size of the EBS volume
            volumeType: "gp2",
            deleteOnTermination: true,
        },
    }],
});

export const launchConfigName = launchConfiguration.id;

Summary

In this guide, we created an AWS Auto Scaling Launch Configuration using Pulumi in TypeScript. We specified the instance type, AMI ID, security group, key pair, user data, and block device mappings. This ensures that all instances launched by the Auto Scaling group will have consistent settings.
