+# 🌐 Node Management with Kubernetes
 
-## Node Management
+Efficient management of Kubernetes nodes ensures cluster stability and workload flexibility. Below are key commands for listing and maintaining nodes.
 
-### Listing Nodes
+---
 
-- **Show All Nodes**
+## 📋 Listing Nodes
+
+### 🔹 Show All Nodes
+```bash
+kubectl get nodes
+````
+
+### 🔹 Show Nodes with Labels
+
+```bash
+kubectl get nodes --show-labels
+```
+
+---
+
+## 🔧 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).
+
+* Forcefully drain the node:
 
   ```bash
-  kubectl get nodes
+  kubectl drain <node-name> --ignore-daemonsets --force
   ```
 
-
-  ```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).
+* Drain and delete local data:
 
   ```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.
+#### 🔄 Undo Drain (Uncordon)
 
+```bash
+kubectl uncordon <node-name>
+```
