EC2 Creation

Terraform is IAC i.e. Infrastructure as Code which leverages code to create Infrastructure resource in any of the cloud provider that support terraform.

We create two files main.tf and provider.tf in main.tf we specify the resources with their configuration to create and in provider.tf we declare information about the cloud provider at we are creating resources.

Here is the simple Terraform code to create aws_instance resource in aws platform.

File Name: main.tf

resource "aws_instance" "a" {
  ami           = "ami-0c614dee691cbbf37"
  instance_type = "t2.micro"
  key_name = "my-key"
 
  tags = {
    Name = "HelloWorld"
  }
}

File Name: provider.tf

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "5.80.0"
    }
  }
}
 
provider "aws" {
  region = "us-east-1"
}

To apply the execution plan we run terraform plan This shows us detailed view of what changes going to take place. and with terraform apply we make these changes.
