Parallel Ansible provision with 2 muti-machine configuration

Vagrant
1

I’m trying to setup a mock environment of Vault and Consul clusters with Vagrant, and using Ansible to provision the environment. However, I’m unable only make the provision happen only once. I tried using flags but it seems the order of evaluation makes this not working as intended. Can someone explain? Thanks in advance.

Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  vault_up = false
  consul_up = false

  VUALT_NODE_COUNT = 3
  CONSUL_NODE_COUNT = 5

  # Define Vault Node
  (1..VUALT_NODE_COUNT).each do |machine_id|
    config.vm.define "vault_#{machine_id}" do |machine|
      machine.vm.box = "generic/debian12"
      machine.vm.hostname = "vault#{machine_id}"
      machine.vm.provider :libvirt do |virt|
        virt.memory = 1024
      end

      if machine_id == VUALT_NODE_COUNT
        vault_up = true
      end
    end
  end
  
  # Define Consul Node
  (1..CONSUL_NODE_COUNT).each do |machine_id|
    config.vm.define "consul_#{machine_id}" do |machine|
      machine.vm.box = "generic/debian12"
      machine.vm.hostname = "consul#{machine_id}"
      machine.vm.provider :libvirt do |virt|
        virt.memory = 1024
      end

      if machine_id == CONSUL_NODE_COUNT
        consul_up = true
      end
    end
  end

  puts "vault_up: #{vault_up}"
  puts "consul_up: #{consul_up}"
  if vault_up && consul_up
    config.vm.provision :ansible do |ansible|
      ansible.compatibility_mode = "2.0"
      ansible.limit = "all"
      ansible.playbook = "playbook.yml"
      ansible.groups = {
        "vault" => (1..VUALT_NODE_COUNT).map { |i| "vault_#{i}"},
        "consul" => (1..CONSUL_NODE_COUNT).map { |i| "consul_#{i}"}
      }
    end
  end
end
