1. Add loop & count (conditional) function in Terraform script to get the value from Frontend.
2. First need to add the function in Terraform script and then need to pass the value from HTML to PHP -> Python as terraform plan -var

Updated Main.tf and variable.tf as following:

resource "google_compute_instance" "node" {
  count = var.number_of_nodes
  name = "ansible-node${count.index}"
  machine_type = var.node_instance
  tags = [
    "ansible",
    "node${count.index}"]
  boot_disk {
    initialize_params {
      image = var.image
    }
  }
  network_interface {
    network = "default"
    access_config {
    }
  }
   metadata_startup_script = file("${path.module}/Ansible_node.sh")
}

Making changes in code to accept EIP values to be able to render in Ansible_master.sh
