Terraform with Azure: Complete Module Development

Terraform modules make infrastructure reusable. Here’s how to build production-ready Azure modules.

Module Structure

modules/
└── azure-webapp/
    ├── main.tf
    ├── variables.tf
    ├── outputs.tf
    └── README.md

Variables

variable "name" {
  description = "Web app name"
  type        = string
}
variable "sku" {
  description = "App Service SKU"
  type        = string
  default     = "B1"
}

Usage

module "webapp" {
  source = "./modules/azure-webapp"
  name   = "myapp"
  sku    = "P1v2"
}
