[SOLVED] "Variables may not be used here" during terraform init

"Variables may not be used here" during terraform init

I am using Terraform snowflake plugins. I want to use ${terraform.workspace} variable in terraform scope.

terraform {
  required_providers {
    snowflake = {
      source  = "chanzuckerberg/snowflake"
      version = "0.20.0"
    }
  }
  backend "s3" {
    bucket         = "data-pf-terraform-backend-${terraform.workspace}"
    key            = "backend/singlife/landing"
    region         = "ap-southeast-1"
    dynamodb_table = "data-pf-snowflake-terraform-state-lock-${terraform.workspace}"
  }
}

But I got this error. Variables are not available in this scope?

Error: Variables not allowed

  on provider.tf line 9, in terraform:
   9:     bucket         = "data-pf-terraform-backend-${terraform.workspace}"

Variables may not be used here.


Error: Variables not allowed

  on provider.tf line 12, in terraform:
  12:     dynamodb_table = "data-pf-snowflake-terraform-state-lock-${terraform.workspace}"

Variables may not be used here.

Solution

Set backend.tf
```
terraform {
  backend "azurerm" {}
}
```

Create a file backend.conf

storage_account_name = "deploymanager"
container_name       = "terraform"
key                  = "production.terraform.tfstate"

Run:

terraform init -backend-config=backend.conf
