Kubernetes provides a mechanism for providing storage to containers called Persistent Volumes. Persistent Volumes support several underlying storage protocols, but clients are needed to support each type. Native GlusterFS and Ceph clients will be added to the Atomic host base to support new Persistent Volume types. | |||

Atomic Storage Clients
Summary
Kubernetes provides a mechanism for providing storage to containers called Persistent Volumes. Persistent Volumes support several underlying storage protocols, but clients are needed to support each type. Native GlusterFS and Ceph clients will be added to the Atomic host base to support new Persistent Volume types.

Detailed Description
By design, Docker container internal storage is ephemeral in nature and data is lost when a container is stopped. Kubernetes uses Persistent Volumes to provide a means for containers to keep data for extended periods of time and between restarts.
A Persistent Volume (PV) in Kubernetes represents a real piece of underlying storage capacity in the infrastructure. Persistent volumes are intended for "network volumes" like NFS shares, GlusterFS volumes, or Ceph devices.
In order to access the underlying storage, the appropriate drivers must be available to Kubernetes on the Atomic host. We will add the appropriate packages to support the following Persistent Volume types:
- GlusterFS
- Ceph
