User Story

As an infrastructure engineer, I will use this work when I want to bootstrap windows server boxes with chef-clients.

Description

The Windows Server boxes are configured with TLS 1.2 and fails due to the generated powershell script (wget.ps1) from knife to download the chef-client with the following error:

The underlying connection was closed: An unexpected error

Chef Version

12+

Platform Version

Chef is running on Ubuntu 16
Chef-client on Windows Server 2016 TLS 1.2

Steps taken to fix the issue at the moment:

cd /opt/chefdk/embedded/lib/ruby/gems/2.5.0/gems/knife-windows-1.9.6/lib/chef/knife/core/
edit windows_bootstrap_context.rb by adding

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Like so....

param(
[String] $remoteUrl,
[String] $localPath
)

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$ProxyUrl = $env:http_proxy;
$webClient = new-object System.Net.WebClient;

if ($ProxyUrl -ne '') {
$WebProxy = New-Object System.Net.WebProxy($ProxyUrl,$true)
$WebClient.Proxy = $WebProxy
}

$webClient.DownloadFile($remoteUrl, $localPath);

Requested resolution

Please allow for some type of switch that will add the Service Point Manager Security Protocol of tls1.2 when bootstrapping chef-clients with
knife bootstrap windows winrm
