Title: Building a Basic VPC on AWS Using Terraform



Are you diving into the world of cloud infrastructure and looking to set up your Virtual Private Cloud (VPC) on AWS? Terraform simplifies this process, allowing you to define your infrastructure as code. In this article, I'll guide you through creating a basic VPC on AWS using Terraform.

Why Terraform?

Terraform is a popular Infrastructure as Code (IaC) tool that enables you to manage your infrastructure declaratively. With Terraform, you define the desired state of your infrastructure using configuration files, and Terraform handles the rest, ensuring your infrastructure matches the defined configuration.

Getting Started

First, ensure you have Terraform installed on your local machine. You can download Terraform from the official website and follow the installation instructions for your operating system.

Once installed, create a new directory for your Terraform configuration files. In this directory, create a file named main.tf and open it in your preferred text editor.

Defining the VPC

In main.tf, start by defining the AWS provider and the VPC resource:

`#hashicorp language

provider "aws" {

region = "us-east-1" # Set your desired region

}

resource "aws_vpc" "my_vpc" {

cidr_block = "10.0.0.0/16" # Set the CIDR block for your VPC

tags = {

Name = "my-vpc"

}

}


In this configuration, we specify the AWS provider and define a VPC resource named "my_vpc" with the CIDR block 10.0.0.0/16. Feel free to adjust the CIDR block to suit your requirements.

Adding a Subnet

Next, let's add a subnet to our VPC:

```hcl

resource "aws_subnet" "my_subnet" {

vpc_id = aws_vpc.my_vpc.id

cidr_block = "10.0.1.0/24" # Set the CIDR block for your subnet

availability_zone = "us-east-1a" # Set your desired availability zone

tags = {

Name = "my-subnet"

}

}


In this snippet, we define a subnet named "my_subnet" within the VPC we created earlier. Adjust the CIDR block and availability zone according to your preferences.

Applying the Configuration

Save your main.tf file and navigate to the directory containing it using your terminal or command prompt. Initialize your Terraform configuration by running:

terraform init

Then, apply the configuration to create your VPC:


terraform apply

Terraform will prompt you to confirm the changes before proceeding. Type yes to apply the configuration.


Congratulations! You've successfully created a basic VPC on AWS using Terraform. This is just the beginning of your journey with Terraform, as it offers many more features for managing your infrastructure efficiently.

In future articles, we'll explore advanced Terraform concepts and tackle more complex infrastructure setups. Stay tuned for more!
