OmnibusUpdater

Update your omnibus! This cookbook can install the omnibus
Chef package into your system if you are currently running
via gem install, and it can keep your omnibus install up
to date.

Usage

Add the recipe to your run list and specify what version should
be installed on the node:

knife node run_list add recipe[omnibus_updater]

In your role you'll likely want to set the version (it defaults
to the 0.10.10 version of Chef):

override_attributes(
  :omnibus_updater => {
    :version => '10.16.2'
  }
)

It can also uninstall Chef from the system Ruby installation
if you tell it to:

override_attributes(
  :omnibus_updater => {
    :remove_chef_system_gem => true
  }
)

---

If you are using a Chef version earlier than 10.12.0 you may want
to take a look at the chef_gem cookbook to ensure gems are going
where expected.

---

The default recipe will install the omnibus package based
on system information but you can override that by using
the install_via attribute which accepts: deb, rpm or script.

Features

Auto version expansion

Versions for the omnibus installer are defined as: x.y.z-n If the :version attribute only provides
x.y.z the n value will be automatically filled in with the latest available version.

Auto version searching

Using the :version_search attribute, the latest stable version of the omnibus installer will
be installed automatically as they become available.

Release clients

Release clients can be installed via the auto-installation using :allow_release_clients attribute.

Disable

If you want to disable the updater you can set the disabled
attribute to true. This might be useful if the cookbook is added
to a role but should then be skipped for example on a Chef server.
