[SIG Storage][] is responsible for storage and volume plugin components.

For the 1.8 release, SIG Storage extended the Kubernetes storage API. In addition to providing simple
volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and

  * Mediates issue [#36859](https://github.com/kubernetes/kubernetes/pull/36859). StatefulSet only acts on Pods whose identity matches the StatefulSet, providing a partial mediation for overlapping controllers.

### Taints and Tolerations

- Fixed bug where health check could pass while APIServices are missing from aggregated discovery. ([#122883](https://github.com/kubernetes/kubernetes/pull/122883), [@Jefftree](https://github.com/Jefftree))

- Added new k8s.io/component-helpers repository providing shared helper code for (core) components. ([#92507](https://github.com/kubernetes/kubernetes/pull/92507), [@ingvagabund](https://github.com/ingvagabund)) [SIG Apps, Node, Release and Scheduling]

- Finished initial generic controlplane refactor of kube-apiserver, providing a sample binary building a Kubernetes-like control plane, but without container orchestration resources. ([#124530](https://github.com/kubernetes/kubernetes/pull/124530), [@sttts](https://github.com/sttts)) [SIG API Machinery, Apps, Cloud Provider,...

- Profiling can now be served on a unix-domain socket by using the `--profiling-path` option (when profiling is enabled) for security purposes. ([#114191](https://github.com/kubernetes/kubernetes/pull/114191), [@apelisse](https://github.com/apelisse)) [SIG API Machinery]

### SIG Scheduling

- Fixed PersistentolumeLabel providing wrong topology labels to Azure Disk PersistentVolumes when the external Azure cloud provider is used. ([#124528](https://github.com/kubernetes/kubernetes/pull/124528), [@jsafrane](https://github.com/jsafrane)) [SIG Cloud Provider]

    * [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.
* CRI has been moved to package `pkg/kubelet/apis/cri/v1alpha1/runtime`. ([#47113](https://github.com/kubernetes/kubernetes/pull/47113), [@feiskyer](https://github.com/feiskyer))
