Question

I want to enable the Kube-proxy mode to IPVS in the existing cluster. currently, it is running on IPtables. how can I change it to IPVS without affecting the existing worklo

Answer 1

Edit the configmap

kubectl edit configmap kube-proxy -n kube-system

change mode from "" to ipvs

mode: ipvs

Kill any kube-proxy pods

kubectl get po -n kube-system
kubectl delete po -n kube-system <pod-name>

Verify kube-proxy is started with ipvs proxier

kubectl logs [kube-proxy pod] | grep "Using ipvs Proxier"
