Terraform Config Generator

Builds a minimal but valid Terraform configuration skeleton, a provider block for AWS, Azure (azurerm), or Google Cloud, a matching compute resource (aws_instance, azurerm_linux_virtual_machine, or google_compute_instance) with name, size, region, and tags, plus a companion variable declaration and output stub, entirely in your browser. A free online tool from Staaarter, right in your browser.

Overview

Introduction

Every Terraform root module starts the same way: a provider block, one resource, a variable or two, and an output to confirm what got created. Typing that boilerplate from memory for a provider you don't touch often means re-checking the exact argument names every time.

This tool generates that starting skeleton for AWS, Azure, or Google Cloud, a provider block, a common compute resource with name/type/region/tags, a matching variable declaration, and an output stub, entirely client-side.

What Is Terraform Config Generator?

A Terraform main.tf generator that produces a provider block plus one representative compute resource, aws_instance for AWS, azurerm_linux_virtual_machine for Azure, or google_compute_instance for Google Cloud, along with the variables the resource references and an output exposing its ID.

The output is plain HCL text you can paste straight into a main.tf file or use as a reference for the correct argument names and block structure for that provider.

How Terraform Config Generator Works

You pick a provider, then fill in a resource name, an instance/machine type, a region (or location), and any number of key/value tags.

The tool assembles a provider block, the corresponding resource block with provider-appropriate argument names (instance_type vs. size vs. machine_type), a variables block declaring the inputs the resource references, and an output block exposing the created resource's ID, all validated to be syntactically well-formed HCL.

When To Use Terraform Config Generator

Use it when starting a new Terraform module and you want a correct skeleton for a specific provider's compute resource without hunting through provider documentation for exact argument names.

It's also handy for quickly comparing how the same conceptual resource, a VM, is expressed differently across AWS, Azure, and Google Cloud's Terraform providers.

Features

Advantages

  • Produces provider-correct argument names (instance_type for AWS, size for Azure, machine_type for Google) instead of a generic placeholder structure.
  • Includes the variable declarations and output block the resource actually references, not just the resource block in isolation.
  • Runs entirely in the browser, nothing you type is sent anywhere.

Limitations

  • Only generates one resource type per provider (a virtual machine/instance); it doesn't cover storage, networking, or IAM resources.
  • Doesn't create supporting resources the skeleton references, such as an Azure resource group or network interface, you still need to define those.

Examples

AWS instance skeleton

Input

provider: aws, resourceName: web, instanceType: t3.micro, region: us-east-1, tags: [{Name: web-server}]

Output

provider "aws" {
  region = var.region
}

resource "aws_instance" "web" {
  ami           = var.ami_id
  instance_type = var.instance_type

  tags = {
    Name = "web-server"
  }
}

variable "region" {
  type        = string
  description = "Region (or location) to deploy into."
  default     = "us-east-1"
}

variable "instance_type" {
  type        = string
  description = "Machine/instance size."
  default     = "t3.micro"
}

variable "ami_id" {
  type        = string
  description = "AMI ID to launch the instance from."
}

output "web_id" {
  description = "ID of the created resource."
  value       = aws_instance.web.id
}

AWS requires an explicit ami_id variable since AWS has no default image, so the generator adds that variable automatically alongside region and instance_type.

Best Practices & Notes

Best Practices

  • Rename the generated resource label from the default to something descriptive of its role (e.g. web, db, bastion) before committing it.
  • Pin the provider version in a separate `required_providers` block rather than relying on whatever version Terraform happens to fetch.
  • Move hardcoded defaults like region into a terraform.tfvars file per environment instead of editing the variable's default directly.

Developer Notes

The generator maps each provider to one representative resource type (aws_instance, azurerm_linux_virtual_machine, google_compute_instance) and renders provider-specific argument names and required companion resources as comments/expectations rather than pretending they don't exist; Google Cloud's tags render as a `labels` map since GCP has no native tags concept on compute instances, while AWS and Azure both use `tags`.

Terraform Config Generator Use Cases

  • Scaffolding a new Terraform module's first resource without re-deriving argument names from provider docs
  • Producing a quick side-by-side comparison of the same VM resource across three cloud providers
  • Teaching or demonstrating Terraform's HCL resource/variable/output structure

Common Mistakes

  • Applying the AWS skeleton without supplying a real ami_id, since AWS instances always require an explicit AMI.
  • Forgetting that the Azure skeleton references a resource group and network interface that must be defined elsewhere in the module.

Tips

  • Use the Terraform Backend Generator next to add remote state storage for the module this resource lives in.
