Summary

  • PVs are Kubernetes resources that abstract the users from how the storage is provisioned.

  • Developers request and manage persistent storage for their pods and VMs by creating PVC resources.

  • VM disks use PVs as their back-end storage.

  • Red Hat OpenShift Virtualization adds the Data Volume resource type.

  • A Data Volume resource simplifies the creation of VM disks by grouping a PVC definition and the disk image to inject into the volume.

  • Kubernetes supports two ways of provisioning storage: static and dynamic.

    • With static provisioning, cluster administrators must prepare volumes manually.

    • With dynamic provisioning, Kubernetes creates persistent volumes on demand.
