2.write a terraform script where you create a linux ec2 instance with security group and key defined so you should be able to use key to login to ec2 instance.

terraform{
  Required_Providers {
   linux ec2 instance ={
   source = "hashicorp/linux ec2"
   version = "~>3.27
}
}
provider "linux" {
  profile = "jyoshna"
  region = "us-west-2"
  access_key = " "
  secret_key = " "
}
resource "linux_security_group " allow key to login"{
name = "devopsschool"
description = " allow key to login ec2 instance" 
}
