An important aspect of Kubernetes is container communication within the Pod. Additionally, an important area of managing the Kubernetes network is to forward container ports internally and externally to make sure containers within a Pod communicate with one another properly.

For most cases, it is sufficient to use a directory on the host that is shared with all containers within a Pod.

If that Pod is deleted for any reason, even if an identical replacement is created, the shared Volume is also destroyed and created from scratch.

The Volume in this exercise provides a way for containers to communicate during the life of the Pod.
