### flexVolume
FlexVolume is an out-of-tree plugin interface that has existed in Kubernetes
since version 1.2 (before CSI). It uses an exec-based model to interface with
drivers. The FlexVolume driver binaries must be installed in a pre-defined volume
plugin path on each node and in some cases the control plane nodes as well.
{{< feature-state for_k8s_version="v1.23" state="deprecated" >}}
Pods interact with FlexVolume drivers through the `flexvolume` in-tree volume plugin.
For more details, see the [FlexVolume](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-storage/flexvolume.md) examples.

{{< note >}}
FlexVolume is deprecated starting v1.23. Out-of-tree CSI driver is the recommended way to write volume driver in Kubernetes. Maintainers of FlexVolume driver should implement a CSI Driver and move users of FlexVolume to CSI. Users of FlexVolume should move their workloads to CSI Driver.
FlexVolume is deprecated. Using an out-of-tree CSI driver is the recommended way to integrate external storage with Kubernetes.
Maintainers of FlexVolume driver should implement a CSI Driver and help to migrate users of FlexVolume drivers to CSI.
Users of FlexVolume should move their workloads to use the equivalent CSI Driver.
