How to update/Patch Kube-proxy config?

10/3/2018

I am using Rancher for Kubernetes Installation and cluster Management. For fixing issue related to IP Tables I need to update the cluster-cidr attribute in Kubeproxy config (https://github.com/kubernetes/kubernetes/issues/36835 ), I am not sure how to update the kube-proxy. Can someone tell me how to update it via Kubectl or UI or how to login to kubeproxy and chnage it?

if we are talking about the Kubernetes:

  1. find the directory /etc/kubernetes on your node
  2. there will be some files and directories, you need to find where the manifests store (something like kube-proxy.manifest, which is a .yml file )
  3. open it and there you'll find --cluster-cidr, it is an option to command:

command: - /hyperkube - proxy - ... - --cluster-cidr=<your_CIDR>

(actually command is a list in YAML implementation, and the --cluster-cidr is a member of this list)

Note: depending on deploying tool (including the Rancher) this directory structure/file names might be different
