Ask for user input in Vagrantfile during provisioning phase

Vagrantfile.rb

  if Dir.glob("#{File.dirname(__FILE__)}/.vagrant/machines/#{VM_NAME}/*").empty? || ARGV[1] == '--provision'
    print "Please insert your credentials\n"
    print "Username: "
    username = STDIN.gets.chomp
    print "Password: "
    password = STDIN.noecho(&:gets).chomp
    print "\n"

    config.vm.provision :shell, :path => "provision-vagrant.sh", :args => [username, password]
  end

Hello Can you help me out a bit with the if Dir.glob("#{File.dirname(FILE)}/.vagrant/machines/#{VM_NAME}/*").empty? || ARGV[1] == '--provision' please , the problem I'm having is that the prompt gets executed on every vagrant command , i only need to run it on vagrant up

for anyone else coming up on this - VM_NAME needs to be your VM name. Try replacing it with default or look at the location .vagrant/machines for the directory and you will see.

Super helpful, thanks! I used this basic idea to create shared folders for two related repos in the same VM:

  print "Enter the path to the sites repo: "
  sites_repo_path = STDIN.gets.chomp
  print "\n"

  # Share an additional folder to the guest VM. The first argument is the path on the host to the actual folder.
  # The second argument is the path on the guest to mount the folder.
  config.vm.synced_folder "./", "/var/www/html", group: "www-data", user: "vagrant"
  config.vm.synced_folder sites_repo_path + '/app/Config/Sites', "/var/www/html/app/Config/Sites", group: "www-data", user: "vagrant"
