= Proposed Self Contained Change: Atomic Storage Clients = https://fedoraproject.org/wiki/Changes/AtomicStorageClients Change owner(s): * mmicene <nzwulfin AT gmail DOT com > Kubernetes provides a mechanism for providing storage to Pods via volumes. 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 these 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 Volumes to provide a means for Pods keep data for extended periods of time and between container restarts. A Volume in Kubernetes represents a real piece of underlying storage capacity in the infrastructure. Persistent Volumes are a way for users to "claim" a Volume without knowing the details of the particular storage environment. Persistent volumes are intended for "network volumes" like NFS shares, iSCSI devices, GlusterFS volumes, or Ceph devices. Persistent Volumes also exist past the Pod lifecycle. 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 Volume types: * GlusterFS * RBD (Ceph Block Device) Both projects currently have packages available and accepted in Fedora for general use. No new packaging should be required. == Scope == Proposal owners: * Add GlusterFS client Fedora packages to Atomic package list * Add Ceph client Fedora packages to Atomic package list -- The Ceph packaging will be changing to reduce the number of dependencies. This may cause some bloat in the image until fixed.
