Friday Quickie: Fixing Kubernetes connectivity with Docker for Windows

Another aide-memoire - when using kubectl on Windows against Docker for Windows you get the following error:

Unable to connect to the server: dial tcp [::1]:8080: connectex: No connection could be made because the target machine actively refused it.

This might well just just be that the tool can't find it's config... and the fix is easy - just set an environment variable:

KUBECONFIG=c:\users\joel\.kube\config

Restart your powershell instance and try again... Simple. (see also this issue in github)
