Hi, How to configure correct config file path for Kubeproxy. Because I am not able to see any kubeproxy folder inside /var/lib directory. Can someone help me to finish this one.

Mohamed Ayman:
Hello @Anushka hasini,
This file is inside the pod. try to exec into the pod first kubectl exec -it -n kube-system <kube-proxy-pod-name> -- /bin/sh

  1. Check the logs of the kube-proxy pods
    kubectl -n kube-system logs <name_of_the_kube_proxy_pod>

  2. The configuration file /var/lib/kube-proxy/configuration.conf is not valid. The configuration path does not match the data in the ConfigMap.
    kubectl -n kube-system describe configmap kube-proxy shows that the file name used is config.conf which is mounted in the kube-proxy daemonset pods at the path /var/lib/kube-proxy/config.conf

  3. However in the DaemonSet for kube-proxy, the command used to start the kube-proxy pod makes use of the path /var/lib/kube-proxy/configuration.conf.
    Correct this path to /var/lib/kube-proxy/config.conf as per the ConfigMap and recreate the kube-proxy pods.
    This should get the kube-proxy pods back in a running state.

Anushka hasini:
Where should I correct this path, I mean which file

Anushka hasini:
Got it now. Thanks

Mohamed Ayman:
Welcome, and happy learning!

Hi, How should one know whether cluster has network addon installled or not

Anushka hasini:
Do we have any commands to verify it

Mohamed Ayman:
Try this to check is there a network add-on pods or not kubectl get pod -n kube-system

Anushka hasini:
Yeah, But I thought kube-proxy is a network components

Anushka hasini:
Do we need to install weave net for accessing services over network

Anushka hasini:
Hi, I have given kubectl get pods -n kube-system

Anushka hasini:
I am getting output like this

I am not able to go inside kube-proxy container. It says below error msg

Anushka hasini:

Please next time format the terminal output as code, like that

First of all double check the logs, then in kube-system namespace you can find a kube-proxy configmap.
In the cm there are 2 entries related to the proxy configuration. Double check the entry withe the one in the .yaml file

Shwetha:
logs, pod events tell you whats wrong with the pod in most cases. If that doesnt help, like Pita suggested have a look at the config provided (config maps, cmd, args etc. )

Anushka hasini:
ok thank you

Hi Mohamed,

I checked the config file but i didn’t find config.conf path

here is the image its says kubeconfig.conf then how should it is looking for config.conf path ?
