In mock exam 3, on Controlplane node we are not able to see the kubelet service or it’s binary. How’s that possible? How static pods are running then? I can see the kubelet configuration file which is inside /usr/lib/kubelet directory.

controlplane $ cd /var/lib/kubelet/
controlplane $ ls
config.yaml  cpu_manager_state  device-plugins  kubeadm-flags.env  pki  plugins  plugins_registry  pod-resources  pods
controlplane $ systemctl status kubelet
Failed to connect to bus: No such file or directory
controlplane $ which kubelet
controlplane $ k get po -n kube-system

@John Paul ^^

Tej_Singh_Rana:
Don’t be confused if a kubelet is not available in the master noded. If you run the same command in the worker nodes, you will see the kubelet. In a master node, only required services are running.

okay @Tej_Singh_Rana
