+## Node Management
+
+### Listing Nodes
+
+- **Show All Nodes**
+
+  ```bash
+  kubectl get nodes
+  ```
+
+
+  ```bash
+    kubectl get nodes --show-lables
+  ```
+
+### Node Maintenance (Cordon/Drain)
+
+- **Cordon a Node**  
+  Prevent new pods from being scheduled on the node.
+
+  ```bash
+  kubectl cordon <node-name>
+  ```
+
+- **Uncordon a Node**  
+  Mark the node as schedulable again.
+
+  ```bash
+  kubectl uncordon <node-name>
+  ```
+
+- **Drain a Node**  
+  Evict all pods from the node (excluding those managed by DaemonSets).
+
+  ```bash
+  kubectl drain <node-name> --ignore-daemonsets --delete-local-data
+  ```
+
+  > **Warning:** Draining a node will evict running pods. Ensure that you plan this action to avoid service disruption.
