🚀 Launch and Configure a Webserver using Terraform

This guide provides a step-by-step approach to launching, connecting to, and configuring a webserver on AWS using Terraform. You'll learn how to configure Terraform, manage AWS resources, and ensure a successful deployment.

---

✅ Prerequisites

Before getting started, ensure you have the following installed and configured:

• 🛠 Terraform - Installed and configured.
• ☁️ AWS CLI - Installed and configured with your access and secret keys using:

  aws configure

• 🔧 Git - Installed to manage your Terraform code repository.

---

📌 Step-by-Step Guide

1️⃣ Launch EC2 Instance 🏗️

Begin by launching an EC2 instance via the AWS Management Console or using a predefined Terraform configuration.

2️⃣ Connect to EC2 Instance 🔗

Connect to your EC2 instance securely via SSH using the appropriate key pair.

3️⃣ Install Terraform and Dependencies 🌍

If Terraform is not already installed, follow the installation steps. Also, ensure that AWS CLI is properly set up:

# Install Terraform (if not installed)
# Configure AWS CLI
aws configure

4️⃣ Install Git 🛠️

Install Git on your EC2 instance to manage your Terraform configuration files:

sudo yum install git -y
git --version
git config --global user.name "your_username"
git config --global user.email "your_email@example.com"

5️⃣ Clone the Repository 📂

Clone the repository containing the Terraform configurations:

git clone https://github.com/YogitaBadhe/aws-terraform-webserver ☁️
cd aws-terraform-webserver ☁️

Alternatively, create the project files manually using PowerShell:

mkdir terraformproject
cd .\terraformproject\
New-Item main.tf
New-Item variables.tf
code .
mkdir aws
cd aws
mkdir aws_keys
cd .\aws_keys\

6️⃣ Create a Key Pair 🔑

Create an AWS key pair named mywebserver.pem through the AWS Management Console. Save it in the aws/aws_keys/ directory and set proper permissions:

chmod 400 aws/aws_keys/mywebserver.pem

7️⃣ Update Terraform Configuration 📜

Modify the main.tf file to include:

• AWS region settings.
• VPC ID, Subnet ID, and AMI ID.
• Key pair name for SSH access.

Also, update variables.tf to include the key pair name.

8️⃣ Initialize and Apply Terraform Configuration ⚙️

Run the following Terraform commands to deploy your resources:

terraform init
terraform validate
terraform fmt
terraform plan
terraform apply

9️⃣ Verify Deployment 🔍

Once Terraform completes the deployment, retrieve the public IP address of the instance and verify the webserver by accessing it via a web browser.

🔟 Clean Up 🗑️

To remove all deployed resources, run:

terraform destroy

1️⃣1️⃣ Commit and Push Code 💾

Save your changes and push them to a GitHub repository:

git add .
git commit -m "Initial commit"
git push origin main

For private repositories, use your GitHub token:

git push https://token@github.com/username/terraform-webserver.git

🎉 Congratulations! You've successfully deployed and configured a webserver on AWS using Terraform! 🚀
