How do I select AMIs and instance types for new EC2 instances?

In this guide, we will demonstrate how to select Amazon Machine Images (AMIs) and instance types for new EC2 instances using Pulumi. We will create an EC2 instance by specifying an AMI ID and an instance type. This will involve using the aws.ec2.Instance resource from the Pulumi AWS package.

Key Points:

• We will define an AMI ID to specify the Amazon Machine Image to use.
• We will choose an instance type to determine the hardware configuration.
• We will create an EC2 instance with the specified AMI and instance type.

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

// Define the AMI ID and instance type
const amiId = "ami-0c55b159cbfafe1f0"; // Example AMI ID for Amazon Linux 2
const instanceType = "t2.micro"; // Example instance type

// Create a new EC2 instance
const ec2Instance = new aws.ec2.Instance("myEc2Instance", {
    ami: amiId,
    instanceType: instanceType,
    tags: {
        Name: "my-ec2-instance",
    },
});

// Export the instance ID and public DNS
export const instanceId = ec2Instance.id;
export const publicDns = ec2Instance.publicDns;

Summary:

In this example, we defined an AMI ID and an instance type to create a new EC2 instance using Pulumi. The aws.ec2.Instance resource was used to provision the instance, and we exported the instance ID and public DNS for reference. This approach allows you to programmatically manage EC2 instances with specific configurations using Pulumi.
