How to Use Terraform to implement Infrastructure as a code

Step 1: Install Terraform

Download Terraform from:

https://developer.hashicorp.com/terraform/downloads

Steps:

1. Download Terraform

2. Extract ZIP file

3. Add Terraform path to environment variables

4. Verify installation

Open terminal and type:

terraform -version

If installed correctly, Terraform version will be displayed.

Step 2: Create Project Folder

Create a new folder:

terraform-demo

Inside the folder create a file:

main.tf

Step 3: Write Terraform Code

Open main.tf and write the following code.

Example: Create a simple local file using Terraform.

terraform {  required_providers {    local = {      source = "hashicorp/local"      version = "2.4.0"    }  }}provider "local" {}resource "local_file" "example" {  filename = "demo.txt"  content  = "Hello, this file is created using Terraform Infrastructure as Code."}

Step 4: Initialize Terraform

Open terminal in the project folder and run:

terraform init

This command downloads required providers.

Output:

Terraform has been successfully initialized

Step 5: Check Execution Plan

Run:

terraform plan

Terraform will show what resources will be created.

Example output:

Plan: 1 to add, 0 to change, 0 to destroy

Step 6: Apply Configuration

Run:

terraform apply

Type:

yes

Terraform will create the file.

Step 7: Verify Output

Check your folder.

You will see:

demo.txt

Open the file.

Content:

Hello, this file is created using Terraform Infrastructure as Code.

Step 8: Destroy Infrastructure

To remove the resource run:

terraform destroy

Type:

yes

Terraform will delete the created file.

Result

Terraform successfully created and managed infrastructure using Infrastructure as Code.
