Hello All,

I am practicing CKA labs…

Reg: Quiz No: 2 (Practice Test Troubleshoot Network)

I tried my self to find the issue…, but I could not…

finally I checked the Hint given and came to know that the config file name was wrong in kube-proxy daemonset

  • command:
    - /usr/local/bin/kube-proxy
    - --config=/var/lib/kube-proxy/configuration.conf (should be “config.conf”)

Here I have doubt…

When I looked for the same file in the master node…
I could not find the kube-proxy dir…

controlplane $ cd /var/lib/
controlplane $ pwd
/var/lib
controlplane $ ls
AccountsService dhcp ieee-data nfs snapd usb_modeswitch
apt docker initramfs-tools ntp sudo usbutils
atomic dockershim kubelet os-prober systemd vim
binfmts dpkg logrotate pam ubuntu-release-upgrader weave
cni etcd man-db plymouth ucf
command-not-found gems misc polkit-1 update-manager
containerd git mlocate private update-notifier
dbus grub NetworkManager python ureadahead
controlplane $

if the dir is not present how it works… or else where exactly the dir exists…

Please correct/help me if I am wrong anywhere…

NOTE: But, yes… once I changed the filename to config.conf… it is working fine…

Mohamed Ayman:
The Configmap is a key-value pair so if you tried this command:
kubectl -n kube-system describe configmap kube-proxy
you can see config.conf that used in the daemon set and the Path kubeconfig: /var/lib/kube-proxy/kubeconfig.conf file is located inside config.conf in the container.

Please see in the volume mounts and volumes in that definition file. You can find that location inside the pod (kubectl exec).
