AWS-EC2-Terraform

This project demonstrates how to provision a publicly accessible AWS EC2 instance using Terraform.

Prerequisites

• You need to have an AWS account and an IAM user with sufficient permissions to create and manage EC2 resources.

• You need to have an SSH key pair generated and uploaded to AWS. You can use the following command to generate a key pair:

  ssh-keygen -t rsa -b 4096 -f my_ssh_keypair_name

  Then, you can use the AWS CLI or the AWS console to upload the public key to AWS.

• You need to have Terraform installed on your machine.

  Windows:

  winget install Hashicorp.Terraform

  MacOS:

  brew install terraform

  Linux:

  sudo apt-get update && sudo apt-get install -y gnupg software-properties-common curl

  curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -

  sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

  sudo apt-get update && sudo apt-get install terraform```

• You need to have the AWS CLI installed and configured with your AWS credentials. You can follow the instructions here.

Instructions

• Clone this repository or download the code as a zip file.

  git clone https://github.com/user/AWS-EC2-Terraform.git

• Navigate to the project directory and open the main.tf file. Replace the value of key_name with your SSH key pair name.

  # Create an EC2 instance
  resource "aws_instance" "my_ec2_instance" {
    ami           = "ami-0fc5d935ebf8bc3bc" # Ubuntu 22.04 Jammy
    instance_type = "t2.micro"              # Instance type
    key_name      = "my_ssh_keypair_name"   # SSH key pair name
  
    tags = {
      Name = "MyEC2Instance"
    }
  }

• Initialize Terraform by running the following command:

  terraform init

  This will download the necessary plugins and modules for the project.

• Apply the Terraform configuration by running the following command:

  terraform apply

  This will create the EC2 instance, security group, elastic IP, and EBS volume as defined in the main.tf file. You will be prompted to confirm the changes before applying them.

• Go to the AWS console and navigate to the EC2 dashboard. You should see the EC2 instance that was created by Terraform.

• Once the apply is complete, you will see the output of the public IP address of your EC2 instance. You can use this IP address to connect to your instance via SSH.

  ssh -i my_ssh_keypair_name ubuntu@<public_ip>

• To destroy the resources created by Terraform, run the following command:

  terraform destroy

  This will delete all the resources and free up any charges incurred by them. You will be prompted to confirm the changes before destroying them.
