Kubernetes doesn't provide data persistence out of the box, which means when a pod is re-created, the data is gone.
So, you need to create and configure the actual physical storage and manage it by yourself. Once configured, you can use that physical storage using Kubernetes storage components. In this video I show you 3 different Kubernetes volume components, that you need to use to connect the actual physical storage to your pod, so that the application inside the container can access it.

The 1st component "Persistent Volume" is a cluster resource, like CPU or RAM, which is created and provisioned by administrators. The 2nd component "Persistent Volume Claim" on the other hand is a user's or pod's request for a persistent volume. With the 3rd component "Storage Class" you can dynamically provision Persistent Volume component and so automate the storage provisioning process.
