One mode of proxy is available on Windows platforms: 'kernelspace'.</p>

is <code>iptables</code> on Linux and <code>kernelspace</code> on Windows). If the selected proxy mode cannot be
used (due to lack of kernel support, missing userspace components, etc) then kube-proxy
will exit with an error.</p>
