How to enable the WRR for kube-proxy

Hi,
I understand that kube-proxy supports so many algorithm like round robin, weighed round robin and all… By default it is round robin… How to change as WRR.
Also how to set the weight for each node and each pod?

Cluster information:

Kubernetes version: 1.15.3
Cloud being used: (put bare-metal if not on a public cloud) On-premises
Installation method: kubespray
Host OS: centos

Can you explain what weight means to you? There isn’t a weight primitive, but it has been discussed. I would like to understand the ways people want to use it and the problems they are having.
