We will follow this tutorial step by step: [https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/](https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/)

You need to:

• Copy the 2 files and apply them
• Check that the storage worked correctly
• Find out what is missing for it to work
• Create it manually or follow the rest of the tutorial which goes through the Kustomize tool (note: Kustomize adds a suffix to the resources it creates)

We can then observe the different objects created, and optimize the process with a more complete `kustomization.yaml` file.

• Enter one of the pods, and from the inside, read the secret that has been made accessible to it.

Let's study and launch this YAML together:
