Solution (Step by Step) :
1. Create a Storage Class:
- Create a storage class YAML file with the desired storage class name and parameters, such as 'accessModes', 'reclaimPolicy' , and 'provisioner'.

- Apply the YAML file using 'kubectl apply -f mysql-storage.yaml' 2. Create a PersistentVolumeClaim: - Create a PVC YAML file With the storage class defined, and specify the storage size and access modes for the PVC.

- Apply the YAML file using 'kubectl apply -f mysql-pvc.yamr 3. Define the StatefulSet: - Update the 'mysql-statefulset' YAML file: - Set the 'spec-template-spec-containers-volumeMounts' to mount the 'mysql-pvc' volume to the container- - Define a 'spec-volumeClaimTemplates' section to define the volume claim associated with the StatefulSet.

- Apply the YAML file using 'kubectl apply -f mysql-statefulset.yamr 4. Verify the StatefulSet: - Check the status of the StatefulSet using 'kubectl get sts mysql-statefulset' - Use ' kubectl describe pod mysql-o' to verify that the 'mysql-pvc' is mounted to the pod and the storage class is being used 5. Test Pod Replacement: - Delete a pod within the StatefulSet (e.g., 'kubectl delete pod mysql-O'). - Observe that a new pod is automatically created witn the same name Cmysql-ff) and the 'mysql-pvc' is mounted to it. 6. Monitor the Database: - Connect to the MySQL database using the 'kubectl exec' command and verify that the data is preserved even after a pod restan or replacement. These steps ensure that your mysql-statefulset utilizes a specific storage class for data persistence and the PVC is always mounted to the same pod, providing consistent data access. ,
