KIND:     PersistentVolumeClaim
VERSION:  v1RESOURCE: spec <Object>DESCRIPTION:Spec defines the desired characteristics of a volume requested by a podauthor. More info:https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaimsPersistentVolumeClaimSpec describes the common attributes of storagedevices and allows a Source for provider-specific attributesFIELDS:accessModes  <[]string>AccessModes contains the desired access modes the volume should have. Moreinfo:https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1dataSource   <Object>This field can be used to specify either: * An existing VolumeSnapshotobject (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC(PersistentVolumeClaim) If the provisioner or an external controller cansupport the specified data source, it will create a new volume based on thecontents of the specified data source. If the AnyVolumeDataSource featuregate is enabled, this field will always have the same contents as theDataSourceRef field.dataSourceRef        <Object>Specifies the object from which to populate the volume with data, if anon-empty volume is desired. This may be any local object from a non-emptyAPI group (non core object) or a PersistentVolumeClaim object. When thisfield is specified, volume binding will only succeed if the type of thespecified object matches some installed volume populator or dynamicprovisioner. This field will replace the functionality of the DataSourcefield and as such if both fields are non-empty, they must have the samevalue. For backwards compatibility, both fields (DataSource andDataSourceRef) will be set to the same value automatically if one of themis empty and the other is non-empty. There are two important differencesbetween DataSource and DataSourceRef: * While DataSource only allows twospecific types of objects, DataSourceRef allows any non-core object, aswell as PersistentVolumeClaim objects.* While DataSource ignores disallowed values (dropping them), DataSourceRefpreserves all values, and generates an error if a disallowed value isspecified. (Alpha) Using this field requires the AnyVolumeDataSourcefeature gate to be enabled.resources    <Object>Resources represents the minimum resources the volume should have. IfRecoverVolumeExpansionFailure feature is enabled users are allowed tospecify resource requirements that are lower than previous value but muststill be higher than capacity recorded in the status field of the claim.More info:https://kubernetes.io/docs/concepts/storage/persistent-volumes#resourcesselector     <Object>A label query over volumes to consider for binding.storageClassName     <string>Name of the StorageClass required by the claim. More info:https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1volumeMode   <string>volumeMode defines what type of volume is required by the claim. Value ofFilesystem is implied when not included in claim spec.volumeName   <string>VolumeName is the binding reference to the PersistentVolume backing thisclaim.
