Vagrantfile: name virtual hosts in single file - vagrant

Question

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

Answer 1

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)

Answer 2

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
