Chef Infra Client 16.13.16 Released!

Hey Everyone,

We had some great stuff ready to ship for Chef Infra Client and we just couldn't resist shipping it all so 16.13 is ready for you today. There are some nice new features as well as a new release of Ruby with several bug fixes and 2 CVE fixes.

What's New

Chef InSpec 4.31

Chef InSpec has been updated from 4.29.3 to 4.31.1.

New Features

  • Commands can now be set to timeout using the command resource or the --command-timeout option in the CLI. Commands timeout by default after one hour.
  • Added the --docker-url CLI option, which can be used to specify the URI to connect to the Docker Engine.
  • Added support for targeting Linux and Windows containers running on Docker for Windows.

Bug Fixes

  • Hash inputs will now be loaded consistently and accessed as strings or symbols. (#5446)

Ubuntu FIPS Support

Our Ubuntu packages are now FIPS compliant for all your FedRAMP needs.

Chef Language Additions

We now include a centos_stream_platform? helper to determine if your CentOS release is a standard CentOS release or a CentOS Stream release. This helper can be used in attributes files, recipes, and custom resources. Thanks for this new helper @ramereth!

Resource Improvements

dsc_script and dsc_resource

Our PowerShell integration has been improved to better handle failures that were silently occurring when running some DSC code in Chef Infra Client 16.8 and later. Thanks for reporting this problem @jeremyciak!

Platform Support Updates

Ubuntu 16.04 EOL

Packages will no longer be built for Ubuntu 16.04 as Canonical ended maintenance updates on April 30, 2021. See Chef's Platform End-of-Life Policy for more information on when Chef ends support for an OS release.

Improved System Detection

Ohai now includes a new :OsRelease plugin for Linux hosts that includes the content of /etc/os_release. This data can be very useful for accurately identifying the Linux distribution that Chef Infra Client is running on. Thanks for this new plugin @ramereth!
