This took me a bit to gather all the details together so I wanted to document this and maybe provide some usefulness to others. There are a number of plugins, features, configurations tricks that I’ve found extremely useful over the last several years for working with Vagrant and Chef. Below is a sample Vagrantfile that can be used as a template and is hopefully commented enough to be self explanatory. You’ll need the following plugins installed:

vagrant plugin install vagrant-berskhelf
vagrant plugin install vagrant-omnibus
vagrant plugin install vagrant-cachier
vagrant plugin install vagrant-vbguest
vagrant plugin install vagrant-hostmanager

Vagrant File:

#-----------------------------------------------------#
#- Project: vagrant-based
#- Author.: john.lawson@scriobha.im
#- Date...: 2015-03-16
#- Notes..: Base template should be usable with a dual scenario
#-----------------------------------------------------#

#- Defaults
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |c|

    #- Caching section to speed local dev/usage don't remove! -#
    if Vagrant.has_plugin?("vagrant-cachier")
        #- Configure scope
        c.cache.scope = :box

        # Enable Apt cache
        c.cache.enable :apt

        # Disable this for actual development use as this will cause issues in file refresh
        #c.cache.enable_nfs = true
    end
    #- END Caching ------------------------------------------ -#

    #- Configure vagrant-hostmanager plugin ----------------- -#
    #- Use this for managing multiple instances, mimics
    #- AWS OpsWorks DNS by hostname functionality
    if Vagrant.has_plugin?("vagrant-hostmanager")
        c.hostmanager.enabled = true
