kubernetes client-go plugin exec command not found on Windows 10

Solution 1:

Kubernetes client-go already have helper methods for authentication using kubeconfig. It contains two variants with good examples:

• Out of cluster authentication example
• In cluster authentication example

I would recommend to use two built-in helper methods instead of rolling a custom variant. You may perhaps want to add an argument so that you can switch between the two, e.g. using out-of-cluster when running locally on Windows and in-cluster when the app (if your code is an app?) is running as a service in the cluster.

Solution 2:

There is little documentation on using kubeconfig under Windows, so with a lot trial and error and a little help from @mdaniel's comment I came up with the following solution:

I created a Windows batch file that contains one line: @python <path-to-script> %* and referenced that file with full path in command: under exec:.

I had to use %* because python script takes parameters.

@ prevents Windows from echoing this command in console when running batch.

I couldn't do command: <path-to-python>\python <path-to-script> because kubernetes still complained it couldn't find the executable with such name.

Also, as a side note, if you use Windows environment variables like %userprofile% in kubeconfig, they need to be referenced inside single quotes.
