OpenShift Enterprise provides the following provisioner plug-ins, which have
generic implementations for dynamic provisioning that use the cluster’s
configured cloud provider’s API to create new storage resources:
|Provisioner Plug-in Name
|Required Cloud Configuration
Configuring for OpenStack
AWS Elastic Block Store (EBS)
Configuring for AWS
For dynamic provisioning when using multiple clusters in different zones, each
node must be tagged with
GCE Persistent Disk (gcePD)
Configuring for GCE
In multi-zone configurations, PVs must be created in the same region/zone as
the master node. Do this by setting the
failure-domain.beta.kubernetes.io/zone PV labels to match the master node.
For any chosen provisioner plug-ins, the relevant cloud configuration must also
be set up, per Required Cloud Configuration in the above table.
When your OpenShift Enterprise cluster is configured for EBS, GCE, or Cinder, the
associated provisioner plug-in is implied and automatically enabled. No
additional OpenShift Enterprise configuration by the cluster administration is
required for dynamic provisioning.
Future provisioner plug-ins will include the many types of storage a single
provider offers. AWS, for example, has several types of EBS volumes to offer,
each with its own performance characteristics; there is also an NFS-like storage
option. More provisioner plug-ins will be implemented for the supported storage
types available in OpenShift Enterprise.
