Create AWS EC2 with Terraform

Hi everyone! 👋 Today, I’ll show you how I created an AWS EC2 instance using Terraform. If you are new to this, don’t worry—I'll keep it simple and easy to follow. Let’s get started! 🚀

What is Terraform?

Terraform is a tool that helps you create and manage cloud resources like servers (EC2), storage, and more. Instead of clicking around in the AWS console, you write a file that tells Terraform what you want. Then, it creates everything for you.

Step 1: Things You Need

Before starting, make sure you have these tools ready:

Terraform installed on your computer.
AWS CLI installed and set up with your AWS account credentials.

If you don’t have them installed, you can find the installation guides here:

Step 2: Write the Configuration File

Create a file named main.tf and copy this code:

provider "aws" {
  region = "ap-south-1"  
}

resource "aws_instance" "example" {
  ami = "ami-0dee22c13ea7a9a67"  
  instance_type = "t2.micro"  

  tags = {
    Name = "Example-demo"  
  }
}

Here’s what the code does:

The provider block tells Terraform to use AWS and sets the region (I used ap-south-1).
The resource block creates an EC2 instance with the specified AMI (Amazon Machine Image) and instance type (t2.micro).
The tags give a name to the instance so it’s easy to identify.

Step 3: Run Terraform Commands

After writing the file, open your terminal and run these commands:

Initialize Terraform
```
 terraform init
```
This command sets up Terraform and downloads the necessary plugins.
Check the Plan
```
 terraform plan
```

This shows what Terraform will create. It’s like a preview before making changes.

Create the Instance
```
 terraform apply
```

When you run this, Terraform will ask for confirmation. Type yes to continue.

Step 4: EC2 Instance Created!

That’s it! After running the terraform apply command, my EC2 instance was created successfully. 🎉

Here’s what it looked like:

Conclusion

Using Terraform makes creating cloud resources like EC2 instances super easy. You just write a file, run a few commands, and everything is ready.

Try it yourself, and let me know how it goes! If you found this helpful, share it with others. 😊
