A Vagrant plugin that ensures the desired version of Chef is installed via the
platform-specific Omnibus packages. This proves very useful when using Vagrant
with provisioner-less baseboxes OR cloud images.

The plugin should work correctly with most all providers that hook into 
`Vagrant::Action::Builtin::Provision` for provisioning and is 
known to work with the following 
[Vagrant providers](http://docs.vagrantup.com/v2/providers/index.html):

* VirtualBox (part of core)
* AWS (ships in [vagrant-aws](https://github.com/mitchellh/vagrant-aws) plugin)
* Rackspace (ships in [vagrant-rackspace](https://github.com/mitchellh/vagrant-rackspace)
  plugin)
* VMWare Fusion (can be [purchased from Hashicorp](http://www.vagrantup.com/vmware))
* LXC (ships in [vagrant-lxc](https://github.com/fgrehm/vagrant-lxc))

## Installation

Ensure you have downloaded and installed Vagrant 1.1.x from the
[Vagrant downloads page](http://downloads.vagrantup.com/).

Installation is performed in the prescribed manner for Vagrant 1.1 plugins.

```
$ vagrant plugin install vagrant-omnibus
```

## Usage

The Omnibus Vagrant plugin automatically hooks into the Vagrant provisioning
middleware. You specify the version of the Chef Omnibus package you want
installed using the `omnibus.chef_version` config key. The version string
should be a valid Chef release version or `:latest`.

Install the latest version of Chef:

```ruby
Vagrant.configure("2") do |config|

  config.omnibus.chef_version = :latest

  ...

end
```

Install a specific version of Chef:

```ruby
Vagrant.configure("2") do |config|

  config.omnibus.chef_version = "11.4.0"

  ...

end
```

This plugin is also multi-vm aware so it would possible to say install a 
different version of Chef on each VM:

```ruby
Vagrant.configure("2") do |config|

  config.vm.define :new_chef do |new_chef_config|

    ...

    new_chef_config.omnibus.chef_version = :latest

    ...

  end

  config.vm.define :old_chef do |old_chef_config|

    ...

    old_chef_config.omnibus.chef_version = "10.24.0"

    ...

  end
end

```

## Tests

### Unit

The unit tests can be run with:

```
rake test:unit
```

The test are also executed by Travis CI every time code is pushed to GitHub.

### Acceptance

Currently this repo ships with a set of basic acceptance tests that will:

* Provision a Vagrant instance.
* Attempt to install Chef 11.4.0 using this plugin.
* Perform a very basic chef-solo run to ensure Chef is in fact installed.

The acceptance tests are run against the Vagrant providers mentioned above. The
acceptance tests can be run with:

```
rake test:acceptance
```

And as expected, all acceptance tests only uses provisioner-less baseboxes and
cloud images!
