Getting a Windows Node on OpenShift
… Not what this post is about, follow the Red Hat and Microsoft documentation and then consult with your certified Red Hat Solutions Architect or Consultant.
Now that I have a windows node
- <WARNING> Administering a windows node is highly discouraged and will probably result in an unsupported configuration. In order to install nerdctl, log into the necessary Windows Node and switch to PowerShell.

Append to System PATH - Permanently
Borrowing commands from a friendly blogger we need to append a new entry to the system PATH. Permanently Modify System Path Run these:
rem Show Current Path
PS C:\Users\Administrator> $ENV:PATH
rem Save Current Path to a variable
PS C:\Users\Administrator> $oldpath = (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment' -Name PATH).path
rem Add a new folder for our binary
PS C:\Users\Administrator> mkdir C:\bin
rem Change directory to the new folder
PS C:\Users\Administrator> cd C:\bin
PS C:\bin> $newpath = "$oldpath;C:\bin"
rem Update System Path
PS C:\bin> Set-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment' -Name PATH -Value $newPath
rem Verify the Path
PS C:\bin> (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment' -Name PATH).Path
rem Reboot node - or close out of your shells and relogin
Restart-Computer -Force
Download and install nerdctl.exe
With all that yak shaving out of the way we can get to it. Find the latest windows release (nerdctl-x.y.z-windows-amd64.tar.gz) nerdctl-1.0.0-windows-amd64.tar.gz nerdctl releases
rem start Powershell and change to the bin folder
rem Download the release file.
PS C:\bin> curl https://github.com/containerd/nerdctl/releases/download/v1.0.0/nerdctl-1.0.0-windows-amd64.tar.gz -o nerdctl-1.0.0-windows-amd64.tar.gz
rem Extract nerdctl.exe from the compressed file
PS C:\bin> tar -xzvf nerdctl-1.0.0-windows-amd64.tar.gz
x nerdctl.exe
rem Delete the compressed file
PS C:\bin> rm nerdctl-1.0.0-windows-amd64.tar.gz
rem Test a nerdctl.exe command
PS C:\bin> nerdctl.exe ps
