Modules variables as a file

I have a terraform module that looks like below

module "newserver" {
  source = "./newserver"

  // passing the variables here
}

Instead of passing the variables there, can i pass them as a file in the command like below terraform apply -var-file="/path/variables.tfvars" When i do that, i am getting errors like missing required argument, what am i missing here, any help on this would be appreciated.

Your module has variables defined inside it with variable blocks such as

variable "example_var" {}

When you instantiate the module, you'll need to pass the required variable into the module. If you want to pass variables into the module when you instantiate it, you'll also have to define those variables as well

module "newserver" {
  source = "./newserver"

  example_var = var.example_var
}

variable "example_var" {}

Terraform is scoped so that variables are scoped inside of modules, you'll have to make a new variable if you instantiate a module and want to pass variables into it
