Feature Request: Environment Variable Overrides for Terraform Provider Source Hostname and Namespace

Summary

Source: https://github.com/straubt1/terraform-registry-address/tree/provider-source-default-environment-variable

This proposal introduces support for two environment variables, TF_PROVIDER_SOURCE_HOSTNAME and TF_PROVIDER_SOURCE_NAMESPACE, that override the hostname and namespace components of provider source addresses at runtime, without requiring any changes to module source code. Together, these are targeted, low-risk enhancements that eliminate repetitive boilerplate from large-scale enterprise Terraform deployments and improve operational flexibility.

Installing the amd64 version of Terraform on Mac with M1

Not all Terraform providers are built for arm64.

One solution here is to install Terraform as amd64 which can be easily done from the downloads page.

However, for those who are using and switching between versions of Terraform often, a more streamlined approach is desirable.

Enter asdf.

# Using the 'random_pet' resource to drive the example and treating the "prefix" argument as a secret.

variable "pets" {
  description = "Map of 'random_pets' to create. These would be any non-sensitive values used to configure the resource."
  type = map(object({
    length    = number
    separator = string
  }))

  # default for easy demo
