What happened?

Nearly every function raises the following error when using version 0.14.2 and above. Does not happen with version 0.14.1:

Anything else?

I am using python 3.11.7 on Windows 11. Running kubectl version I get:

Client Version: v1.29.1
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.29.1-eks-b9c9ed7

Looking at it a little closer I think:

  File "C:\Users\dhorkel\code\python_scratch\.venv\Lib\site-packages\kr8s\_auth.py", line 97, in _load_kubeconfig
    self.kubeconfig = await KubeConfigSet(*self._kubeconfig_path.split(":"))

is splitting the windows filepath at the drive name

Thanks for raising this! I think you're right that the bug was introduced when the multi-path support was added.

In kr8s we don't officially support Windows, we could but that's a separate conversation. However this looks like a quick fix so I'll open a PR to disable multiple config support on Windows.
