The syntax of Vagrantfiles is Ruby (Ruby experience is not necessary). + +The command **vagrant up** creates a *Vagrant Box* based on your Vagrantfile. A Vagrant box is one of the motivations for using Vagrant - its a "development-ready box" that can be copied to other machines to recreate the same environment. + +It's common for people to think that a Vagrant box *is* the VM. But rather, the VM is *inside* a Vagrant box, with the box containing additional configuration options you can set, such as VM options, scripts to run on boot, etc. + +This `Vagrant website for boxes <https://app.vagrantup.com/boxes/search>`_ shows you how to configure a basic Vagrantfile for your specific OS and VM software. + + +Box configuration +_________________ + + +Looking at the :ref:`vppVagrantfile`, we can see that the default OS is Ubuntu 16.04 (since the variable *distro* equals *ubuntu1604* if there is no VPP_VAGRANT_DISTRO variable set - thus the **else** case is executed.) + +.. code-block:: ruby + + # -*- mode: ruby -*- + # vi: set ft=ruby : + + Vagrant.configure(2) do |config| + + # Pick the right distro and bootstrap, default is ubuntu1604 + distro = ( ENV['VPP_VAGRANT_DISTRO'] || "ubuntu1604") + if distro == 'centos7' + config.vm.box = "centos/7" + config.vm.box_version = "1708.01" + config.ssh.insert_key = false + elsif distro == 'opensuse' + config.vm.box = "opensuse/openSUSE-42.3-x86_64" + config.vm.box_version = "1.0.4.20170726" + else + config.vm.box = "puppetlabs/ubuntu-16.04-64-nocm" + +As mentioned in the previous page, you can specify which OS and VM provider you want for your Vagrant box from the `Vagrant boxes page <https://app.vagrantup.com/boxes/search>`_, and setting your ENV variable appropriately in *env.sh*. + +Next in the Vagrantfile, you see some *config.vm.provision* commands. As paraphrased from `Basic usage of Provisioners <https://www.vagrantup.com/docs/provisioning/basic_usage.html>`_, by default these are only run *once* - during the first boot of the box. + +.. code-block:: ruby + + config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"update.sh") + config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"build.sh"), :args => "/vpp vagrant" + +The two lines above set the VM to run two scripts during its first bootup: an update script *update.sh* that does basic updating and installation of some useful tools, as well as *build.sh* that builds (but does **not** install) VPP in the VM. You can view these scripts on your own for more detail on the commands used. + + +Looking further in the :ref:`vppVagrantfile`, you can see more Ruby variables being set to ENV's or to a default value: + +.. code-block:: ruby + + # Define some physical ports for your VMs to be used by DPDK + nics = (ENV['VPP_VAGRANT_NICS'] || "2").to_i(10) + for i in 1..nics + config.vm.network "private_network", type: "dhcp" + end + + # use http proxy if avaiable + if ENV['http_proxy'] && Vagrant.has_plugin?("vagrant-proxyconf") + config.proxy.http = ENV['http_proxy'] + config.proxy.https = ENV['https_proxy'] + config.proxy.no_proxy = "localhost,127.0.0.1" + end + + vmcpu=(ENV['VPP_VAGRANT_VMCPU'] || 2) + vmram=(ENV['VPP_VAGRANT_VMRAM'] || 4096) + + +You can see how the box or VM is configured, such as the amount of NICs (defaults to 3 NICs: 1 x NAT - host access and 2 x VPP DPDK enabled), CPUs (defaults to 2), and RAM (defaults to 4096 MB). + + +Box bootup +__________ + + +Once you're satisfied with your *Vagrantfile*, boot the box with: + +.. code-block:: console + + $ vagrant up + +Doing this above command will take quite some time, since you are installing a VM and building VPP.
