- `CSIMigrationGCEComplete`: Stops registering the GCE-PD in-tree plugin in kubelet and volume controllers and enables shims and translation logic to route volume operations from the GCE-PD in-tree plugin to PD CSI plugin. Requires CSIMigration and CSIMigrationGCE feature flags enabled and PD CSI plugin installed and configured on all nodes in the cluster.
- `CSIMigrationOpenStack`: Enables shims and translation logic to route volume operations from the Cinder in-tree plugin to Cinder CSI plugin. Supports falling back to in-tree Cinder plugin if a node does not have Cinder CSI plugin installed and configured. Requires CSIMigration feature flag enabled.
- `CSIMigrationOpenStackComplete`: Stops registering the Cinder in-tree plugin in kubelet and volume controllers and enables shims and translation logic to route volume operations from the Cinder in-tree plugin to Cinder CSI plugin. Requires CSIMigration and CSIMigrationOpenStack feature flags enabled and Cinder CSI plugin installed and configured on all nodes in the cluster.
- `CSIMigrationvSphere`: Enables shims and translation logic to route volume operations from the vSphere in-tree plugin to vSphere CSI plugin. Supports falling back to in-tree vSphere plugin if a node does not have vSphere CSI plugin installed and configured. Requires CSIMigration feature flag enabled.
- `CSIMigrationvSphereComplete`: Stops registering the vSphere in-tree plugin in kubelet and volume controllers and enables shims and translation logic to route volume operations from the vSphere in-tree plugin to vSphere CSI plugin. Requires CSIMigration and CSIMigrationvSphere feature flags enabled and vSphere CSI plugin installed and configured on all nodes in the cluster.
- `CSINodeInfo`: Enable all logic related to the CSINodeInfo API object in csi.storage.k8s.io.
- `CSIPersistentVolume`: Enable discovering and mounting volumes provisioned through a
[CSI (Container Storage Interface)](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/container-storage-interface.md)
compatible volume plugin.
- `CSIStorageCapacity`: Enables CSI drivers to publish storage capacity information and the Kubernetes scheduler to use that information when scheduling pods. See [Storage Capacity](/docs/concepts/storage/storage-capacity/).
Check the [`csi` volume type](/docs/concepts/storage/volumes/#csi) documentation for more details.
- `CSIVolumeFSGroupPolicy`: Allows CSIDrivers to use the `fsGroupPolicy` field. This field controls whether volumes created by a CSIDriver support volume ownership and permission modifications when these volumes are mounted.
- `CSIVolumeFSGroupPolicy`: Allows CSIDrivers to use the `fsGroupPolicy` field. This field controls whether volumes created by a CSIDriver support volume ownership and permission modifications when these volumes are mounted.
- `CustomCPUCFSQuotaPeriod`: Enable nodes to change CPUCFSQuotaPeriod.
- `CustomPodDNS`: Enable customizing the DNS settings for a Pod using its `dnsConfig` property.
Check [Pod's DNS Config](/docs/concepts/services-networking/dns-pod-service/#pods-dns-config)
