ansible-playbook -i inventory.ini deploywebapp.yml

# main.tf
terraform {
  requiredproviders {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.0"
  }
}
provider "aws" {
  region = "us-east-1"
}
resource "awsinstance" "webservers" {
  count         = 3
  ami           = "ami-0c02fb55956c7d316"
  instancetype = "t3.micro"
  tags = {
    Name = "web-server-${count.index}"
  }
}
