Creating an AWS EC2 instance using Pulumi in the default VPC and subnet

I have been attempting to create an EC2 instance in the default VPC and default subnet using Pulumi TypeScript, but unfortunately, I haven't had any success. In my script, I am trying to retrieve the default VPC ID and assign it as a string. However, I seem to be having trouble achieving this.

export const defaultvpc = new aws.ec2.DefaultVpc("default", {tags: {Name: "Default VPC",}}).id;

Although I am able to obtain the VPC ID in the 'defaultvpc' variable, I am struggling to use it as an argument in the 'getSubnetIds' function.

const subnetIds = aws.ec2.getSubnetIds({vpcId: defaultvpc})

If anyone has insights on how to successfully create an EC2 instance in the default VPC and default subnet, your assistance would be greatly appreciated.

Answer №1

I have finally uncovered the solution and am excited to share it here!

import * as aws from "@pulumi/aws";
import { VpcIpamResourceDiscovery } from "@pulumi/aws/ec2";

const config = new pulumi.Config();

// Fetching the default VPC ID
const defaultVpcId = aws.ec2.getVpc({
    default: true
}).then(vpc => vpc.id);

// Obtaining the default subnet IDs for the default VPC
const defaultSubnetIds = pulumi.all([defaultVpcId]).apply(([vpcId]) =>
    aws.ec2.getSubnetIds({
        vpcId: vpcId
    })
);

// Setting up an EC2 instance in the first default subnet
const instance = new aws.ec2.Instance("my-instance", {
    instanceType: "t2.micro",
    ami: "ami-123456",  // Replace with desired AMI ID
    subnetId: defaultSubnetIds.apply(subnets => subnets.ids[0]),  // Using the first default subnet ID
});

export const instanceId = instance.id;
