Summary

As we mentioned in the introduction, most applications need to store or retrieve data for a lot of different reasons. In this chapter, we saw that Kubernetes provides various ways of provisioning storage for not just storing the state of an application, but also for the long-term storage of data.

We have covered ways to use storage for our application running inside pods. We saw how we can use the different types of Volumes to share temporary data among containers running in the same pod. We also learned how to persist data across pod restarts. We learned how to manually provision PVs to create PVCs to bind to those Volumes, as well as how to create pods that can use these claims as Volumes mounted on their containers. Next, we learned how to request storage dynamically using only the PVCs with pre-created storage classes. We also learned about the life cycle of these volumes with respect to that of the pods.

In the next chapter, we will extend these concepts further...
