-  ```
-- **Get the list of pods in the default namespace with full information:**
-  ```bash
-  kubectl get pod -o wide
-  ```
-- **Get the list of pods in a custom namespace with full information:**
-  ```bash
-  kubectl get pod -o wide -n <name-space>
-  ```
-
-### Running a Pod
-- **Run a new pod:**
-  ```bash
-    kubectl run <pod-name> <switch> {
-    --image=<image-name>,                # Specifies the container image to use
-    --port=<portnumber>,                 # Specifies the port that the container exposes
-    -n <namespace-name>,                 # Specifies the namespace
-    --env="KEY=VALUE",                   # Sets environment variables in the container
-    --command,                           # Treats the rest of the arguments as the command to run in the container
-    --replicas=<number>,                 # Specifies the number of replicas for the deployment
-    --labels="key=value,key2=value2",    # Adds labels to the pod(s)
-    --dry-run=client,                    # Prints the object that would be sent, without creating it
-    --restart=<Always|OnFailure|Never>,  # Determines the restart policy for the pod
-    --overrides='<json>',                # Provides a JSON override for the generated object
-    --image-pull-policy=<policy>,        # Specifies the image pull policy (Always, IfNotPresent, Never)
-    --limits=cpu=<cpu>,memory=<memory>,  # Specifies resource limits for the container
-    --requests=cpu=<cpu>,memory=<memory> # Specifies resource requests for the container
-    }
-  ```
-  - *Example:*
-    ```bash
-      kubectl run mypod --image=nginx --port=80 -n mynamespace \
-      --env="ENV_VAR_NAME=VALUE" --command -- nginx -g "daemon off;" \
-      --replicas=3 --labels="app=myapp,env=prod" --dry-run=client \
-      --restart=Always --overrides='{"spec": {"containers": [{"name": "nginx", "image": "nginx"}]}}' \
-      --image-pull-policy=IfNotPresent --limits=cpu=100m,memory=256Mi \
-      --requests=cpu=50m,memory=128Mi
-    ```

-### Deleting a Pod
-- **Delete a pod in a custom namespace:**
-  ```bash
-  kubectl delete pod -n <namespace-name> <pod-name>
-  ```

-  ```bash
-  kubectl describe pod -n <namespace-name> <podname>
-  ```
-
-### Apply Yaml File
-```bash
-kubectl apply -f <yaml-file> -n <namespace-name>
-```
-### View Pod Details
-
-```bash
-kubectl get pod -n my-ns <pod-name> -o yaml
-```
-
-This command retrieves and displays the YAML configuration of the pod `testpod1` in the namespace `my-ns`.
-
-### Label a Node
-
-```bash
-kubectl label node <node-name> kubernetes.io/<var-name>=<var-value>
-kubectl get nodes --show-labels
-```
-### Retrieve the ReplicaSet
-To retrieve information about the ReplicaSet in the `my-ns` namespace, use the following command:
-```bash
-kubectl get rs -n my-ns
-```
-
-### Delete All Pods in the Namespace
-To delete all pods in the `my-ns` namespace, use the following command:
-```bash
-kubectl delete pod --all -n my-ns
-```
-
-### Change the Replica Count to 5
-To scale the ReplicaSet to 5 replicas, you can use one of the following methods:
-
-1. **Using the `kubectl scale` Command**
-```bash
-kubectl scale rs my-app --replicas=5 -n my-ns
-```
-
-## Commands to Manage the Deployment
-
-### Scale the Deployment
-To scale the Deployment to 6 replicas:
-```bash
-kubectl -n my-ns scale deployment myapp --replicas 6
-```
-
-### Retrieve Deployment, ReplicaSets, and Pods
-To retrieve information about the Deployment, ReplicaSets, and Pods:
-```bash
-kubectl get deployment,rs,po myapp -n my-ns
-```
-
-### Delete the Deployment
-To delete the Deployment:
-```bash
-kubectl delete deployment myapp -n my-ns
-```
-
-### Retrieve ReplicaSets
-To retrieve ReplicaSets:
-```bash
-kubectl get rs -n my-ns
-```
-
-### Rollback a Deployment
-To undo the last rollout:
-```bash
-kubectl rollout undo deployment -n my-ns myapp
-```
-
-To view rollout history:
-```bash

-```
-
-To rollback to a specific revision:
-```bash
-kubectl rollout undo deployment -n my-ns myapp --to-revision 2

-
-### Annotate Deployment with Change Cause
-To add a change cause annotation:
-```bash
-kubectl annotate deployment/myapp -n my-ns myapp "kubectl.kubernetes.io/change-cause=v14 released"
-```
-
-### Horizontal Pod Autoscaler
-To create an autoscaler for the Deployment:
-```bash
-kubectl -n my-ns autoscale deployment nginx --cpu-percent=50 --min=4 --max=10
-```
