* [alpha] Make locally attached (non-network attached) storage available as a persistent volume source. For more information, see [Storage Volumes - local](https://kubernetes.io/docs/concepts/storage/volumes/#local).

#### Volume Plugins

#### **GCP**

*   The service account made available on your nodes is now configurable. ([#52868](https://github.com/kubernetes/kubernetes/pull/52868),[ @ihmccreery](https://github.com/ihmccreery))
*   GCE nodes with NVIDIA GPUs attached now expose nvidia.com/gpu as a resource instead of alpha.kubernetes.io/nvidia-gpu. ([#54826](https://github.com/kubernetes/kubernetes/pull/54826),[ @mindprince](https://github.com/mindprince))

* Fix for Pod stuck in ContainerCreating with error "Volume is not yet attached according to node". ([#50806](https://github.com/kubernetes/kubernetes/pull/50806), [@verult](https://github.com/verult))

- Fixed a bug where a high churn of events was causing master instability by reducing the maximum number of objects (events) attached to a single etcd lease. ([#100084](https://github.com/kubernetes/kubernetes/pull/100084), [@mborsz](https://github.com/mborsz)) [SIG API Machinery, Instrumentation and Scalability]

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached. Kubernetes will make sure they are fully attached before they can be used by pods. ([#120595](https://github.com/kubernetes/kubernetes/pull/120595), [@jsafrane](https://github.com/jsafrane))

## Changelog since v1.12.3

### Action Required

* ACTION REQUIRED: The Node.Status.Volumes.Attached.DevicePath fields is deprecated for CSI volumes and will be unset in a future release ([#71095](https://github.com/kubernetes/kubernetes/pull/71095), [@msau42](https://github.com/msau42))

### Other notable changes

- Add metric etcd_lease_object_counts for kube-apiserver to observe max objects attached to a single etcd lease. ([#97480](https://github.com/kubernetes/kubernetes/pull/97480), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery, Instrumentation and Scalability]

    * [StorageOS](http://www.storageos.com) can be used as a storage provider for Kubernetes.  With StorageOS, capacity from local or attached storage is pooled across the cluster, providing converged infrastructure for cloud-native applications.

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods.
