I am trying to find the kubeproxy logs on minikube, It doesn't seem they are located.
sudo cat: /var/log/kubeproxy.log: No such file or directory
A more generic way (besides what hoque described) that you can use on any kubernetes cluster is to check the logs using kubectl.
kubectl logs kube-proxy-s8lcb -n kube-systemUsing this solution allow you to check logs for any K8s cluster even if you don't have access to your nodes.
Pod logs are located in /var/log/pods/. Run
$ minikube ssh
$ ls /var/log/pods/
