TIL — Conditionally enable a Terraform module

We can conditionally enable or disable a Terraform module for different environments using the count meta-argument.

variable "ENABLE_DB" { 
  type = bool
  default = true 
}

module "database" {
  source = "./modules/database"
  # Conditionally enable module
  count = var.ENABLE_DB ? 1 : 0
}
