18. Vagrant Workflow
    • When you done with the dev environment
    vagrant destroy [vn-name]
    • To access the virtual machine via ssh
    vagrant ssh
    • When you finished work for the day
    vagrant halt
    vagrant up
    • Once Configured one command to bring up you vagrant dev environment

    config.vm.box = "precise64"
    config.vm.box_url = "http://files.vagrantup.com/precise64.box"
    end

22. Box Files
    •Every Vagrant development environment needs a
    box file to build off.
    •Box files are specific to the type of provider.
    http://docs.vagrantup.com/v2/boxes.html
    $ vagrant box add name url

23. Four methods to create a box file
    •Download a box file from http://www.vagrantbox.es
    •Using the instructions off - (not recommended)
    http://docs-v1.vagrantup.com/v1/docs/base_boxes.html
    •VeeWee https://github.com/jedi4ever/veewee
    •Packer http://www.packer.io/docs/builders/virtualbox.html
    In a future version of vagrant packer will be integrated.

25. Provisioning your vagrant machine
    •Need a configuration management tool.
    •Main benefits are ease of use, repeatability,
    automation and improving parity between
    development and production.
