Vagrant shell provisioning with variable arguments. This example iterates through an object and passes its keys and values as parameters to a shell script http://docs.vagrantup.com/v2/provisioning/shell.html It also creates one node for each key, value pair

vagrant-shell-arguments.rb

Vagrant.configure("2") do |config|

  HADOOP_NODES = {'hd-master' => '192.168.40.10',
                  'hd-slave1' => '192.168.40.11',
                  'hd-slave2' => '192.168.40.12'}

  HADOOP_NODES.each do |node_name, node_ip|
    config.vm.provision :shell do |s|
      s.inline = 'echo -e "$1\t$2" | sudo tee -a /etc/hosts'
      s.args = "#{node_ip} #{node_name}"
    end
  end

  HADOOP_NODES.each do |node_name, node_ip|
    config.vm.define node_name.to_sym do |node_config|
      node_config.vm.box = 'precise64'
      node_config.vm.box_url = 'http://files.vagrantup.com/precise64.box'
      node_config.vm.hostname = node_name
      node_config.vm.network :private_network, :ip => node_ip
    end
  end
