Terraform

Terraform is an open source “Infrastructure as Code” tool, created by HashiCorp.

Terraform was in GO Language.It can manage not only existing on-prem solutions but also can work for almost all popular cloud service providers like AWS, Azure, GCP

A declarative coding tool, Terraform enables developers to use a high-level configuration language called HCL (HashiCorp Configuration Language) to describe the desired “end-state” cloud or on-premises infrastructure for running an application. It then generates a plan for reaching that end-state and executes the plan to provision the infrastructure.

Example Terraform program

provider “github” {
token = “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”
owner = “Yarra Lakshmi Bhavani”
}

resource “github_repository” “example” {
name = “Lakshmi Bhavani”
description = “My awesome codebase “

visibility = “public”
}
