Lab Information
The Nautilus DevOps team is strategizing the migration of a portion of their infrastructure to the AWS cloud. Recognizing the scale of this undertaking, they have opted to approach the migration in incremental steps rather than as a single massive transition. To achieve this, they have segmented large tasks into smaller, more manageable units.
For this task, create an EC2 instance using Terraform with the following requirements:
The name of the instance must be xfusion-ec2.
Use the Amazon Linux ami-0c101f26f147fa7fd to launch this instance.
The Instance type must be t2.micro.
Create a new RSA key named xfusion-kp.
Attach the default (available by default) security group.
The Terraform working directory is /home/bob/terraform. Create the main.tf file (do not create a different .tf file) to provision the instance.
Note: Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.

Create main.tf
# main.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 5.0"
}
}
}
provider "aws" {
region = "us-east-1"
}
resource "aws_key_pair" "xfusion_kp" {
key_name = "xfusion-kp"
public_key = tls_private_key.xfusion_rsa.public_key_openssh
}
resource "tls_private_key" "xfusion_rsa" {
algorithm = "RSA"
rsa_bits = 4096
}
resource "aws_instance" "xfusion_ec2" {
ami = "ami-0c101f26f147fa7fd"
instance_type = "t2.micro"
key_name = aws_key_pair.xfusion_kp.key_name
tags = {
Name = "xfusion-ec2"
}
}
resource "local_file" "private_key" {
content = tls_private_key.xfusion_rsa.private_key_pem
filename = "${path.module}/xfusion-kp.pem"
}
To deploy this configuration:
Navigate to the Terraform directory:
cd /home/bob/terraform
Initialize Terraform:
terraform init
Plan the deployment to verify the configuration:
terraform plan
Apply the configuration:
terraform apply
Explanation
This configuration:
Provider Configuration: Sets up the AWS provider for the us-east-1 region.
RSA Key Generation: Creates a new RSA key pair using the tls_private_key resource with 4096 bits.
Key Pair Resource: Creates the AWS key pair named xfusion-kp using the generated public key.
EC2 Instance: Creates the instance with:
Name: xfusion-ec2
AMI: ami-0c101f26f147fa7fd (Amazon Linux)
Instance type: t2.micro
Key pair: xfusion-kp
Security group: Uses the default security group (automatically used when not specified)
Local File: Saves the private key to a file named xfusion-kp.pem in the Terraform directory for SSH access.
Important Notes:
The instance will use the default VPC and default security group
The private key will be saved locally as xfusion-kp.pem - make sure to keep this secure!
You'll need to set proper permissions on the private key file: chmod 400 xfusion-kp.pem
