Chef Workstation 0.18.3 Released!

We are delighted to announce the availability of version 0.18.3 of Chef Workstation.

New features

Kitchen OpenStack

Chef Workstation now ships with Kitchen OpenStack so you can test your Chef Infra cookbooks using instances in OpenStack clouds. See the Kitchen Openstack GitHub repo for usage information. Thanks @ramereth for all the work getting this driver ready to ship in Workstation.

Ubuntu 20.04 Packages

Chef Workstation packages are now created for Ubuntu 20.04! See the Workstation Downloads Page for a complete list of platforms we produce packages for.

Updated Components

Chef Infra Client 15.10

Chef Infra Client has been updated from 15.8 to 15.10 which includes improvements to resources, additional cookbook helpers, and critical bug fixes for bootstrapping nodes using knife bootstrap and SSHing to nodes with ed25519 keys from Windows hosts. For a complete list of changes, see the Chef Infra Client 15.10 release notes

Cookstyle 6.3

Cookstyle has been updated from 5.22 to 6.3. This new release includes an updated RuboCop engine which includes a large number of autocorrection improvements and bug fixes, plus compatibility with Ruby 2.7. Cookstyle also ships with a large number of autocorrection improvements and 18 new Chef Infra cops. Included in the new cops are cops to get your cookbooks ready for Chef Infra Client 16.

Note: The updated RuboCop engine has renamed many of the out-of-the-box Ruby cops which may require updating cop names in your .rubocop.yml config. Additionally, this release will now fail Cookstyle runs if any of the ChefDeprecations department cops that shipped at the time of Cookstyle 5.22 alert. Any new cops we add will be added at the warning level until Cookstyle 7.0 ships. This gives you time to update your cookbooks using the latest Cookstyle releases without immediately failing CI builds.

Fauxhai 8.1

Fauxhai has been updated from 7.6 to 8.1. Fauxhai is the engine that provides ChefSpec with mocked Ohai data, allowing you to writes ChefSpecs for multiple platforms. This release updates all of the mocked Ohai data to be generated with Chef Infra Client 16. It also updates the list of platforms that are included in the mocked data. We've added new platforms and removed deprecated platforms that have generated warnings for the last year. To avoid deprecation warnings in your ChefSpecs in the future, you can avoid specifying the minor versions of releases and instead let ChefSpec choose the latest platform for you. For example, instead of specifying platform: 'centos', version: '7.7.1908' you can instead set platform: 'centos' or platform: 'centos', version: '7'.

Thanks @bdwyertech and @kamaradclimber for these improvements.
