Introduction
With Terraform, you can define and manage cloud resources using configuration files through infrastructure-as-code. In this Project we used Terraform and its integration with AWS by creating a Virtual Private Cloud VPC. In this project, we will use Terraform on a Linux machine, install and configure it, and create an AWS VPC.
Terraform is the Infrastructure as a code IAAC tool which is used to provide resources by writing a code.
Step 1: Go to AWS Account
logging into your AWS account. If you donʼt have an account yet, go ahead and create one.
Step 2: Configure EC2 Instance
Create an EC2 instance to act as your working environment. You can follow this guide to create an EC2 instance.
Step 3: Connect to the Instance
Once your EC2 instance is up and running, connect to it using EC2 Instance Connect. Navigate to the AWS console, find your instance, and click the “Connect” button.
Step 4: Installing Terraform
Now, letʼs install Terraform on your EC2 instance.
Download the Terraform package:
wget <https://releases.hashicorp.com/terraform/1.0.1/terra form_1.0.1_linux_amd64.zip>
Unzip the package and move it to your systemʼs binary folder:
sudo unzip terraform_1.0.1_linux_amd64.zip -d /usr/local/b in/
Remove the downloaded zip file:
rm terraform_1.0.1_linux_amd64.zip
Verify that Terraform was installed correctly:
terraform version
Step 5: Configuring the AWS Provider in Terraform
Create a working directory for Terraform:
mkdir infra && cd infra
Create a Terraform configuration file ( ):
cat > main.tf <<EOF terraform {
required_providers { aws = {
source = “hashicorp/aws” version = “3.48.0”
}
}
}
provider “aws” {
region = “us-west-2” # Oregon
} EOF
Initialize the working directory:
terraform init
List the directories to see what the init command has created:
ls -A
Step 6: Creating an AWS Resource with Terraform
To create an AWS resource, you need to define it in the configuration file.
Append an aws_vpc esource block to your main.tf file:
cat >> main.tf <<EOF
resource “aws_vpc” “web_vpc” {
cidr_block = “192.168.100.0/24” enable_dns_hostnames = true tags = {
Name = “Web VPC”
}
} EOF
Run the Apply command to generate a plan and review the output:
terraform apply
Accept and apply the plan by typing “yes” at the prompt.
Verify that the VPC has been created:
aws ec2 describe-vpcs –region us-west-2 –filter “Name=ta g:Name,Values=Web VPC”
Check if DNS hostnames are enabled for the VPC
aws ec2 describe-vpc-attribute –region us-west-2 –attrib ute enableDnsHostnames –vpc-id <VPC_ID>
Summary
Congratulations! You have successfully created an AWS VPC using Terraform. This project gave you hands-on experience with Terraformʼs core features, such as providers and resource declarations, and allowed you to automate infrastructure setup on AWS. Keep exploring Terraformʼs capabilities to build more complex and scalable cloud environments!
