In this chapter, we explored a variety of persistent storage options and how to implement them with our pods. We looked at PersistentVolumes and also PersistentVolumeClaims, which allow us to separate storage provisioning and application storage requests. Additionally, we looked at StorageClasses for provisioning groups of storage according to a specification.

We also explored the new StatefulSets abstraction and learned how we can deploy stateful applications in a consistent and ordered manner. In the next chapter, we will look at how to integrate Kubernetes with Continuous Integration and Delivery pipelines.
