Installing buildkit on Windows from source

This will set up buildkitd natively on Windows Server 2019 (ltsc2019) or Windows Server 2022 (ltsc2022).

Enable the containers feature

This will reboot your server if the feature is not already installed.

Install-WindowsFeature -Name containers -Restart

Local test env of k8s and containerd (the hard way)

Assumptions:

• You're running on an ubuntu 20.04 VM/physical server
• Your IP address is: 10.198.117.162 (obviously you will need to adust this to your env)
• The hostname of the machine is k8s-test
• The windows node we'll be adding is a Windows Server 2022 (ltsc2022)

Obviously you will need to adust these assumptions to your env. But for clarity we define these assumptions here.
