OpenShift can integrate with underlying infrastructure, enabling OpenShift to dynamically interact with infrastructure and extend its functionality. Specifically, this can allow us to set up OpenShift to process a PersistentVolumeClaim and then allocate that storage dynamically.
I am going to cover what is needed to get started with dynamically provisioning storage, including cloud provider configuration, StorageClasses, and the Default StorageClass.
