Vagrantfile: name virtual hosts in single file

I'm using Vagrant to create three hosts. I want to give them the name node01, node02 and node03.

Using the following Vagrantfile:

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


Vagrant.configure(2) do |config|

  config.vm.define "node01" do |node01|
    node01.vm.box = "ubuntu/trusty64"
    node01.vm.hostname = "node01"
  end

  config.vm.define "node02" do |node02|
    node02.vm.box = "ubuntu/trusty64"
    node02.vm.hostname = "node02"
  end

  config.vm.define "node03" do |node03|
    node03.vm.box = "ubuntu/trusty64"
    node03.vm.hostname = "node03"
  end


  config.vm.provider "virtualbox" do |vb|
     vb.memory = "1024"
   end
end

On virtualbox, the names are cryptic (like ubuntu-3nodes-node01-timestamp ...). How can I ensure they are just called node01, node02 and node03

I know I can do in the config.vm.provider "virtualbox" but I would ideally do it in the config.vm.define "node01" sections

You can also separate loop from define node method.

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

Vagrant.configure(2) do |config|

  config.vm.box = "ubuntu/trusty64"

  def define_node(config, node_number)
    config.vm.define "node0#{node_number}" do |node|
      node.vm.hostname = "node0#{node_number}"

      node.vm.provider "virtualbox" do |vb|
        vb.memory = "1024"
        vb.name = "node0#{node_number}"
      end
    end
  end

  for node_number in 1..3
    define_node config, node_number
  end
end

you can do something like this

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

Vagrant.configure(2) do |config|

  config.vm.box = "ubuntu/trusty64"

  (1..3).each do |i|
    config.vm.define "node0#{i}" do |node|
      config.vm.provider "virtualbox" do |vb|
        vb.memory = "1024"
        vb.name = "node0#{i}"
      end
      node.vm.hostname = "node0#{i}"
    end
  end

end
  • This is some ruby to loop on the node.
  • the box if its the same in all machine can be defined at the upper block level
  • You must make the name of the name of VirtualBox VM in the virtualbox block as it depends on virtualbox (vagrant can manage other provider and this would be different)
