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:


Ensure you have downloaded and installed Vagrant 1.1 or newer from the Vagrant downloads page. If you require Windows support then Vagrant 1.6.1 or newer is needed.

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

$ vagrant plugin install vagrant-omnibus


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 ```

Specify a custom install script:

```ruby Vagrant.configure(“2”) do |config|

config.omnibus.install_url = ‘’ # config.omnibus.install_url = ‘’ # config.omnibus.install_url = ‘/some/path/on/the/host’

end ```

If vagrant-cachier is present and config.cache.auto_detect enabled the downloaded omnibus packages will be cached by vagrant-cachier. In case you want to turn caching off:

```ruby Vagrant.configure(“2”) do |config|

config.omnibus.cache_packages = false

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



config.vm.define :old_chef do old_chef_config

old_chef_config.omnibus.chef_version = "10.24.0"


end end ```



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.


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

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

The acceptance tests can be run against a subset of the Vagrant providers listed above. The acceptance tests can be run with:

rake test:acceptance:PROVIDER_NAME

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