Running on AWS here with opsworks automate, W2K12 practice node, and mac workstation. I can do the hands-on knife bootstrap from the workstation but am trying to do an unattended chef client installation on the windows node but as a manual process first to run so that I have a process to script into powershell. So far from my reading the key components are: first-boot.json, validation.pem, client.rb file from other articles. Though I'm having challenges attempting to get a manual chef client on the windows node to authenticate with the automate server. I've heard all the articles say that the validation.pem key file is crucial to this process, however WHERE is this file generated or located. It's a different key file than the one provided with the private.pem file. Anyone have any experience with this?
