Vagrantfiles
|
|
============
|
|
|
|
A `Vagrantfile <https://www.vagrantup.com/docs/vagrantfile/>`_ contains the box and provision configuration settings for your VM. 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:: shell
|
|
|
|
$ vagrant up
|
|
|
|
Doing this above command will take quite some time, since you are installing a VM and building VPP. Take a break and get some scooby snacks while you wait.
|
|
|
|
To confirm it is up, show the status and information of Vagrant boxes with:
|
|
|
|
.. code-block:: console
|
|
|
|
$ vagrant global-status
|
|
id name provider state directory
|
|
-----------------------------------------------------------------------------------------
|
|
d90a17b default virtualbox poweroff /home/centos/andrew-vpp/vppsb/vpp-userdemo
|
|

|
|
c1c8952 default virtualbox poweroff /home/centos/andrew-vpp/testingVPPSB/extras/vagrant
|
|
c199140 default virtualbox running /home/centos/andrew-vpp/vppsb3/vpp-userdemo
|
|
|
|
You will have only one machine running, but I have multiple as shown above.
|
|
|
|
.. note::
|
|
|
|
To poweroff your VM, type:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ vagrant halt <id>
|
|
|
|
To resume your VM, type:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ vagrant resume <id>
|
|
|
|
To destroy your VM, type:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ vagrant destroy <id>
|
|
|
|
Note that "destroying" a VM does not erase the box, but rather destroys all resources allocated for that VM. For other Vagrant commands, such as destroying a box, refer to the `Vagrant CLI Page <https://www.vagrantup.com/docs/cli/>`_. |
