Terraform Online Test

A company managing public parks is using Terraform modules for their web servers.

The following is a snippet from the module in the web_server folder:

variable "count_of_containers" {
  type = number
}

variable "port_number" {
  type = number
}

resource "docker_image" "park_web_image" {
  name = "parkweb:latest"
}

resource "docker_container" "park_web_server" {
  count = var.count_of_containers
  image = docker_image.park_web_image.latest
  name = "container-${count.index}"
  ports {
    internal = var.port_number
    external = var.port_number
  }
}

How can another module in the same project use it?

A bridge design company is using Terraform to manage containers for programs that compute bridge integrity. The following is a snippet from their main.tf file:

resource "docker_image" "bridge_integrity" {
  name = "bridge_integrity:latest"
}

resource "docker_container" "bridge_integrity_container" {
  count = length(var.container_names)
  image = docker_image.bridge_integrity.latest
  name  = var.container_names[count.index]
  ports {
    internal = 80 
    external = 80
  }
}

variable "container_names" {
  type = list(string)
  default = ["first", "second"]
}

What can be concluded from it?
