Hi Everyone,

We have a new release of Chef Infra Client out today packed full of improvements for configuring the Chef Infra Client, utilizing the latest and greatest PowerShell releases, and remotely executing Chef Infra Client. Be sure to check it out!

## pwsh Support

We've updated multiple parts of the Chef Infra Client to fully support Microsoft's `pwsh` (commonly known as PowerShell Core) in addition to our previous support for `PowerShell`.

### powershell\_script resource

The `powershell_script` resource includes a new `interpreter` property that accepts either `powershell` or `pwsh`.

```ruby
powershell_script 'check version table' do
  code '$PSVersionTable'
  interpreter 'pwsh'
end

```

### powershell\_out / powershell\_exec helpers

The `powershell_out` and `powershell_exec` helpers for use in custom resources have been updated to support `pwsh` with a new argument that accepts either `:pwsh` or `:powershell`.

```ruby
powershell_exec('$PSVersionTable', :pwsh)

```

## Enhanced 32-bit Windows Support

The `powershell_exec` helper now supports the 32-bit version of Windows. This ensures many of the newer PowerShell based resources in Chef Infra Client will function as expected on 32-bit systems.

## New Resources

### chef\_client\_config

The `chef_client_config` resource allows you to manage Chef Infra Client's `client.rb` file without the need for the `chef-client` cookbook.

#### Example

```ruby
chef_client_config 'Create client.rb' do
  chef_server_url 'https://chef.example.dmz'
end

```

#### chef-client Cookbook Future

With the inclusion of the `chef_client_config` resource in Chef Infra Client 16.6, it is now possible to fully manage the Chef Infra Client without the need for the `chef-client` cookbook. We highly recommend using the `chef_client_config`, `chef_client_trusted_certicate`, and `chef_client_*` service resources to manage your clients instead of the `chef-client` cookbook. In the future we will mark that cookbook as deprecated, at which time it will no longer receive updates.

Here's a sample of fully managing Linux hosts with the built-in resources:

```ruby
chef_client_config 'Create client.rb' do
  chef_server_url 'https://chef.example.dmz'
end

chef_client_trusted_certificate "chef.example.dmz" do
  certificate <<~CERT

## Target Mode Improvements

Chef Infra Client 16 introduced an experimental Target Mode feature for executing resources remotely against hosts that do not have a Chef Infra Client or even Ruby installed. For Chef Infra Client 16.6 we've improved this functionality by converting the majority of the Ohai plugins to run remotely. This means when using Target Mode you'll have the majority of Ohai data as if the Chef Infra Client was installed on the node. Keep in mind this data collection can be time consuming over high latency network connections, and cloud plugins which fetch metadata cannot currently be run remotely. Ohai also now includes a `--target` option for remote data gathering, which accepts a Train URI: `ohai --target ssh://foobar.example.org/`. We still consider Target Mode to be an experimental feature, and we'd love your feedback on what works and what doesn't in your environment.

## Updated Resources

### ifconfig

The `ifconfig` resource has been updated to no longer add empty blank lines to the configuration files. Thanks for this improvement [@jmherbst](https://github.com/jmherbst/)!

### windows\_audit\_policy

The `windows_audit_policy` resource has been updated to fix a bug on failure-only auditing.

## Ohai Improvements

### Passwd Plugin For Windows

The optional Ohai `Passwd` plugin now supports Windows hosts in addition to Unix-like systems. To collect user/group data on Windows hosts you can use the `ohai_optional_plugins` property in the new `chef_client_config` resource to enable this plugin.

```ruby
chef_client_config 'Create client.rb' do
  chef_server_url 'https://chef.example.dmz'
  ohai_optional_plugins [:Passwd]
end

```

Thanks for adding Windows support to this plugin [@jaymzh](https://github.com/jaymzh)!

### Improved Azure Detection

The `Azure` plugin has been improved to better detect Windows hosts running on Azure. The plugin will now look for DHCP with the domain of `reddog.microsoft.com`. Thanks for this improvement [@jasonwbarnett](https://github.com/jasonwbarnett/)!

### EC2 IAM Role Data

Ohai now collects IAM Role data on EC2 hosts including the role name and info. To address potential security concerns the data we collect is sanitized to ensure we don't report security credentials to the Chef Infra Server. Thanks for this improvement [@kcbraunschweig](https://github.com/kcbraunschweig)!

## Security

Ruby has been updated to 2.7.2, which includes a fix for [CVE-2020-25613](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25613).

## Get the Build

As always, you can download binaries directly from [downloads.chef.io](https://downloads.chef.io/products/infra?v=16.6.14) or by using the `mixlib-install` command-line utility:

```auto
$ mixlib-install download chef -v 16.6.14

```

Alternatively, you can install Chef Infra Client using one of the following command options:

```auto
# In Shell
$ curl https://omnitruck.chef.io/install.sh | sudo bash -s -- -P chef -v 16.6.14

# In Windows Powershell
. { iwr -useb https://omnitruck.chef.io/install.ps1 } | iex; install -project chef -version 16.6.14

```

If you want to give this version a spin in Test Kitchen, create or add the following to your `kitchen.yml` file:

```auto
provisioner:
  product_name: chef
  product_version: 16.6.14

```

Enjoy,  
Tim
