In order to automate the creation of the resource group, I want to use a generic Terraform script

As an example, the below script creates the resource group in Azure based on the input values provided in the *.tfvars.json file

main.tf

# Configure the Microsoft Azure provider
provider "azurerm" {
  features {}
}

# Create a Resource Group if it doesn’t exist
resource "azurerm_resource_group" "example" {
  name     = var.resource_group_name
  location = "West US"
}

vars.tf

# Input variable: image sku
variable "resource_group_name" {
  description = "Name of the resource group"
  default     = "example-resources"
}

testing.tfvars.json

{
   "resource_group_name":"example-resources-testing"
}

and executed like

terraform apply –auto-approve -var-file=”testing.tfvars.json”

Before creating the new resource group, it destroys the existing one. I don’t want to destroy the existing resource group, just create a new one.

I don’t want to clone the script. What should I do to use the generic Terraform script repeatedly without destroying the existing one?

Solution

You need to create a workspace for each environment.

Workspaces are managed with the terraform workspace set of commands. To create a new workspace and switch to it, you can use terraform workspace new; to switch workspaces you can use terraform workspace select; more info about Managing Workspaces.

Within your Terraform configuration, you may include the name of the current workspace using the ${terraform. Workspace} interpolation sequence.
