 We need to expose the cadvisor that is installed and managed by the kubelet daemon and allow webhook token authentication. To do so, we do the following on **all the masters and nodes**:
 
-    sed -e "/cadvisor-port=0/d" -i /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
-    sed -e "s/--authorization-mode=Webhook/--authentication-token-webhook=true --authorization-mode=Webhook/"
-    systemctl daemon-reload
-    systemctl restart kubelet
+    sudo sed -e "/cadvisor-port=0/d" -i /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
+    sudo sed -e "s/--authorization-mode=Webhook/--authentication-token-webhook=true --authorization-mode=Webhook/" -i /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
+    sudo systemctl daemon-reload
+    sudo systemctl restart kubelet
 
 In case you already have a Kubernetes deployed with kubeadm, change the address kube-controller-manager and kube-scheduler listens **on master node** in addition to previous kubelet change:
 
-    sed -e "s/- --address=127.0.0.1/- --address=0.0.0.0/" -i /etc/kubernetes/manifests/kube-controller-manager.yaml
-    sed -e "s/- --address=127.0.0.1/- --address=0.0.0.0/" -i /etc/kubernetes/manifests/kube-scheduler.yaml
+    sudo sed -e "s/- --address=127.0.0.1/- --address=0.0.0.0/" -i /etc/kubernetes/manifests/kube-controller-manager.yaml
+    sudo sed -e "s/- --address=127.0.0.1/- --address=0.0.0.0/" -i /etc/kubernetes/manifests/kube-scheduler.yaml
