@fredleger Thanks for report.

You're right, it should respect the value of the namespace value in ~/.kube/config. I will mark this report as enhancement, and fix it later, but there's no ETA for the fix. If this feature matter to you, maybe you can try to create a pull-request for the fix FYI, you may find the source code HERE.

Story behind, while I was designing this tool, my initial thought was that having namespace defined explicitly would be safer, especially for production environment. For now, please take this a hard limitation.
