Container Storage Interface (CSI) Storage Plugin Release 1.0.0 (Loopback NFS)

New in this Release

This first release of the Container Storage Interface (CSI) Storage Plugin for NFS includes .yaml configuration files that can be installed onto a Kubernetes cluster. Once installed, these containers provide an NFS-based CSI Driver for the file-system volume plug-in and a Kubernetes Dynamic Volume Provisioner that permit static and dynamic provisioning of data-fabric storage from Kubernetes.

You can access the csi-nfsplugin by installing the custom resource definition (CRD) using the csi-maprnfskdf-v1.0.0.yaml file. Or you can build your own container and point to the plugin on the Docker hub at maprtech/csi-nfsplugin:1.0.0. For installation information, see Installing, Uninstalling, and Upgrading the Container Storage Interface (CSI) Storage Plugin.

Release 1.0.0 also includes support for dynamic and static provisioning of raw block volumes. For more information, see Raw Block Volumes.
