  Getting Started Sohow do we get started? 1) Download tools 2) Define Environment 3) Prosper Tools you’ll need:  Vagrant  http://www.vagrantup.com/  VirtualBox  http://www.virtualbox.org

  Vagrant Commands Thereare many commands to interact with your environment available to you via Vagrant We will discuss some of them in this talk, but they are fully documented here: https://docs.vagrantup.com /v2/cli/index.html Useful Vagrant CLI commands Bring up a VM $ vagrant up Power down a VM $ vagrant halt Reboot a VM $ vagrant reload SSH into a VM $ vagrant ssh Destroy / delete a VM $ vagrant destroy

  Vagrant Providers Vagrantsupports a number of different providers (the technology that creates the virtual environment) For us we’re using the VirtualBox and Amazon EC2 providers as they are “free” Providers are extendable as plug-ins A VMWare provider is also available

  Getting Started Onceyou have the tools the first step in creating your environment is to select a box to use. Boxes are ready to run virtual machines in a variety of OSes A large selection of pre-made boxes are available for use: http://www.vagrantbox.es Debian Ubuntu Windows BSD

  Creating an Environment Vagrant environments are defined through a file called a VagrantFile. To create a stub of this file, from the root of your project execute the following command: $ vagrant init [box name] $ vagrant box add precise64 http://files.vagrantup .com/precise64.box virtualbox $ cd /myproject $ vagrant init precise64

  Tools to helpbuild a Vagrantfile A Vagrantfile as you’ve seen is basically Ruby. There are also a number of online tools available to help you generate these files using a UI if that’s what you prefer. Generate your Vagrantfile online Rove http://rove.io/ PuPHPet http://puphpet.com/

  Vagrant Provisioners Provisionersare various tools (extendable as plug-ins) for configuring the virtual environment Vagrant supports a number of various provisioners out of box, most notably Puppet and Chef Vagrant Provisioners • File • Shell • Ansible • CFEngine • Chef • Docker • Puppet • Salt

  Making the Mostof Vagrant  There are a number of ways to improve your Vagrant experience at various points that are worth mentioning  Streamlining environment creation  Improving performance of the environment  Etc.  Let’s take a look at a few of them.

  Improving Performance There are a number of ways to improve the performance of the virtual environment  Provider Selection –VMWare does better than VirtualBox  For VMWare there are a few things you can do as well  Use NFS to share the project  Use all CPU cores  Use ¼ of system memory
• 16.
  Improving Creation Time  There are a number of things you can do to simply the complexity of using a tool like Vagrant to build environments  Don’t use provisioners  Create skeleton projects
• 17.
  Skipping Provisioners If you want, you don’t necessarily have to use any provisioners at all when using Vagrant  Boot up a box, login, and configure the environment manually  Use vagrant package to create a .box from your configured VM  Provide this to others  Easier, but you lose some visibility and management that you get from provisioners
• 18.
  Creating a Skeleton  IMHO, better than simply packaging boxes is to create a skeleton of your basic projects and build off of them as necessary  I have created said skeleton projects  http://github.com/coogle/skeleton  Same speed in ramp-up time without losing the power of the provisioners
