Examples

Terraform does not allow to use count inside module block.[1]

resource "aws_instance" "dev" {
   ami = "ami-082b5a644766e0e6f"
   instance_type = "t2.micro"
   count = 2
}
resource "aws_instance" "your_new_instance_in_test" {
   ami = "ami-082b5a644766e0e6f"
   instance_type = "t2.micro"
   count = var.istest == true ? 3 : 0
}
resource "aws_instance" "your_new_conditional_instance {
   count = var.your_env == "PRE" ? 1 : 0
   ami = "ami-082b5a644766e0e6f"
   instance_type = "t2.micro"
}


variable "elb_names" {
  type = list
  default = ["dev-loadbalancer", "stage-loadbalanacer","prod-loadbalancer"]
}
 
resource "aws_iam_user" "lb" {
  name = var.elb_names[count.index]
  count = 2
  path = "/system/"
}


resource "aws_ecs_service" "your_service" {
count = var.your_env_name == "PROD" ? 1 : 0
