The Container Storage Interface (CSI) defines a standard interface to expose storage systems to containers.
<!--more-->
CSI allows vendors to create custom storage plugins for Kubernetes without adding them to the Kubernetes repository (out-of-tree plugins). To use a CSI driver from a storage provider, you must first [deploy it to your cluster](https://kubernetes-csi.github.io/docs/Setup.html). You will then be able to create a {{< glossary_tooltip text="Storage Class" term_id="storage-class" >}} that uses that CSI driver.

Flexvolume is an interface for creating out-of-tree volume plugins. The {{< glossary_tooltip text="Container Storage Interface" term_id="csi" >}} is a newer interface which addresses several problems with Flexvolumes.
<!--more-->
Flexvolumes enable users to write their own drivers and add support for their volumes in Kubernetes. FlexVolume driver binaries and dependencies must be installed on host machines. This requires root access. The Storage SIG suggests implementing a {{< glossary_tooltip text="CSI" term_id="csi" >}} driver if possible since it addresses the limitations with Flexvolumes.
