Summary

Persistent storage usage is a daily activity for OpenShift cluster administrators and OpenShift users in a production environment. In this chapter, we briefly discussed persistent storage OpenShift API objects such as PV and PVC. Both PV and PVC allow you to define and use persistent storage. We showed you how to configure basic underlying storage services such as NFS, GlusterFS, and iSCSI, and how to add them to OpenShift's infrastructure via PV objects. Additionally, we worked on requesting persistent storage via PVC objects. Lastly, we showed you a basic example of persistent storage usage from an application point of view.
