+# 🌐 Node Management with Kubernetes
+
+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
+```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 drain <node-name> --ignore-daemonsets --force
+  ```
+
+* Drain and delete local data:
+
+  ```bash
+  kubectl drain <node-name> --ignore-daemonsets --delete-local-data
+  ```
+
+#### 🔄 Undo Drain (Uncordon)
+
+```bash
+kubectl uncordon <node-name>
+```
+
+> ⚠️ **Warning:** Draining a node will evict running pods. Ensure that this is planned to avoid service disruption.
