TFNFR25 - Verified Modules Requirements

ID: TFNFR25 - Category: Code Style - Verified Modules Requirements

The terraform.tf file MUST only contain one terraform block.

The first line of the terraform block MUST define a required_version property for the Terraform CLI.

The required_version property MUST include a constraint on the minimum version of the Terraform CLI. Previous releases of the Terraform CLI can have unexpected behavior.

The required_version property MUST include a constraint on the maximum major version of the Terraform CLI. Major version releases of the Terraform CLI can introduce breaking changes and MUST be tested.

The required_version property constraint SHOULD use the ~> #.# or the >= #.#.#, < #.#.# format.

Note: You can read more about Terraform version constraints in the documentation.

Example terraform.tf file:

terraform {
  required_version = "~> 1.6"
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 3.11"
    }
  }
}
