Release Notes: chef-client 12.7

Chef is a powerful automation platform that transforms infrastructure into code. Whether you’re operating in the cloud, on-premises, or in a hybrid environment, Chef automates how infrastructure is configured, deployed, and managed across your network, no matter its size.

This diagram shows how you develop, test, and deploy your Chef code.

What’s New

The following items are new for chef-client 12.7 and/or are changes from previous versions. The short version:

  • Chef::REST => require ‘chef/rest’ Internal API calls are moved from Chef::REST to Chef::ServerAPI. Any code that uses Chef::REST must use require 'chef/rest'.
  • New chocolatey_package resource Use the chocolatey_package resource to manage packages using Chocolatey for the Microsoft Windows platform.
  • New osx_profile resource Use the osx_profile resource to manage configuration profiles (.mobileconfig files) on the Mac OS X platform.
  • New apt_update resource Use the apt_update resource to manage Apt repository updates on Debian and Ubuntu platforms.
  • Improved support for UTF-8 The chef-client 12.7 release fixes a UTF-8 handling bug present in chef-client versions 12.4, 12.5, and 12.6.
  • New options for the chef-client The chef-client has a new option: --delete-entire-chef-repo.
  • Multi-package support for Chocolatey and Zypper A resource may specify multiple packages and/or versions for platforms that use Zypper or Chocolatey package managers (in addition to the existing support for specifying multiple packages for Yum and Apt packages).

Chef::REST => require ‘chef/rest’

Internal API calls are moved from Chef::REST to Chef::ServerAPI. As a result of this move, Chef::REST is no longer globally required. Any code that uses Chef::REST must be required as follows:

require 'chef/rest'

For code that is run using knife or chef command line interfaces, consider using Chef::ServerAPI instead.

chocolatey_package

Use the chocolatey_package resource to manage packages using Chocolatey for the Microsoft Windows platform.

Syntax

A chocolatey_package resource block manages packages using Chocolatey for the Microsoft Windows platform. The simplest use of the chocolatey_package resource is:

chocolatey_package 'package_name'

which will install the named package using all of the default options and the default action (:install).

The full syntax for all of the properties that are available to the chocolatey_package resource is:

chocolatey_package 'name' do
  notifies                   # see description
  options                    String
  package_name               String, Array # defaults to 'name' if not specified
  provider                   Chef::Provider::Package::Chocolatey
  source                     String
  subscribes                 # see description
  timeout                    String, Integer
  version                    String, Array
  action                     Symbol # defaults to :install if not specified
end

where

  • chocolatey_package tells the chef-client to manage a package
  • 'name' is the name of the package
  • :action identifies which steps the chef-client will take to bring the node into the desired state
  • options, package_name, provider, source, timeout, and version are properties of this resource, with the Ruby type shown. See “Properties” section below for more information about all of the properties that may be used with this resource.
