ec2 instance and security group terraform resource templates are available here

terraform-YouTube

First give provider Information:

• provider.tf

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
}

# Configure the AWS Provider
provider "aws" {
  region = "ap-south-1"
}

Provision EC2-Instance & Security Groups Using Terrafrom:

• ec2.tf

  description = "security group using terraform"
  vpc_id      = "vpc-0d096b2c1d33a1aba"

  ingress {

    from_port        = 443
    to_port          = 443
    protocol         = "tcp"
    cidr_blocks      = ["0.0.0.0/0"]
    ipv6_cidr_blocks = ["::/0"]
  }

  ingress {
