About this Hands-on Lab

PersistentVolumes provide a way to treat storage as a dynamic resource in Kubernetes. This lab will allow you to demonstrate your knowledge of PersistentVolumes. You will mount some persistent storage to a container using a PersistentVolume and a PersistentVolumeClaim.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a PersistentVolume That Allows Claim Expansion

Create a hostPath PersistentVolume with a size of 1Gi that stores data on the host at /var/output. Ensure that this PersistentVolume is configured so that Pod volumes that use it can be expanded later. In addition, configure the volume so that it will be automatically reusable if the claims using it are deleted.

Note that you may need to create other objects in addition to the PersistentVolume object.

Create a PersistentVolumeClaim

Create a PersistentVolumeClaim with a size of 100Mi. Make sure it is able to bind to the PersistentVolume.

Create a Pod That Uses a PersistentVolume for Storage

Create a Pod that uses the PersistentVolume and writes some data to it.

Additional Resources

Your company, BeeBox, is developing some applications for Kubernetes. They are anticipating some increasingly complex storage needs in the future, so they want to make sure that they can leverage the full potential of Kubernetes storage with PersistentVolumes.

Your task is to build an application that uses a PersistentVolume for storage. Ensure that the application's volume is able to be expanded in case its storage needs might increase later.
