What is Terraform?
-------------------------------------------------------
	Coding for Infra = IAAC
	From Hasicorp
	Written in GOlang
	Release

Whats there in Infra?
----------------------------------
https://registry.terraform.io/browse/providers

Why We need terraform?
------------------------------------------------------
So many Platform
So many Lang spec
So many Coding Standard
one is not working for other
Consitent change mgmt

--------------------------------
How it works?

======================================================
Step 1 - Installl Terraform

Step 2 - Install Providers

Step 3 - Write A code

Step 4 - Run a code

Step 5 - Validate the state file

Code language: JavaScript (javascript)

Installl Terraform

Step 2 – Install Terraform Providers (Plugins)

You can install providers using CODE.

How to store terraform code?
---------------------
anyfilename.tf


Directory === file1.tf  + file2.tf + file3.tf
              ================================
			ONE PROJECT
			ONE CODE
All TF code merged into ONE 
			During - Apply - Destory

Azure
AWS
Github

--------------------------------------
terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
      version = "3.75.0"
    }
  }
}

provider "azurerm" {
  # Configuration options
}
--------------------------------------
How to download providers? | First time | Upgrade
$ terraform init


-------------------------------------------------
terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
      version = "3.75.0"
    }
	aws = {
      source = "hashicorp/aws"
      version = "5.20.0"
    }
  }
}

provider "azurerm" {
  # Configuration options
}



provider "aws" {
  # Configuration options
}Code language: PHP (php)

Step 3 – How to write a Code in Terraform?

====================================================
Rule#1 - You MUST know Provider(Azure)
Rule#2 - You MUST know the resources provider by Terrafrom
