PersistentVolumeClaimSpec

PersistentVolumeClaimSpec describes the common attributes of storage devices and allows a Source for provider-specific attributes

Beta level

  • dataSource (TypedLocalObjectReference)

    dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. If the AnyVolumeDataSource feature gate is enabled, this field will always have the same contents as the DataSourceRef field.

  • dataSourceRef (TypedLocalObjectReference)

    dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any local object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the DataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, both fields (DataSource and DataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. There are two important differences between DataSource and DataSourceRef: * While DataSource only allows two specific types of objects, DataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects.

    • While DataSource ignores disallowed values (dropping them), DataSourceRef preserves all values, and generates an error if a disallowed value is specified. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.

PersistentVolumeClaimStatus

PersistentVolumeClaimStatus is the current status of a persistent volume claim.

  • accessModes ([]string)

    accessModes contains the actual access modes the volume backing the PVC has. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1

  • allocatedResources (map[string]Quantity)

    allocatedResources is the storage resource within AllocatedResources tracks the capacity allocated to a PVC. It may be larger than the actual capacity when a volume expansion operation is requested. For storage quota, the larger value from allocatedResources and PVC.spec.resources is used. If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation. If a volume expansion capacity request is lowered, allocatedResources is only lowered if there are no expansion operations in progress and if the actual volume capacity is equal or lower than the requested capacity. This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

  • capacity (map[string]Quantity)

    capacity represents the actual resources of the underlying volume.

  • conditions ([]PersistentVolumeClaimCondition)

    Patch strategy: merge on key type

    conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to ‘ResizeStarted’.

    PersistentVolumeClaimCondition contails details about state of pvc

    • conditions.status (string), required

    • conditions.type (string), required

    • conditions.lastProbeTime (Time)

      lastProbeTime is the time we probed the condition.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.lastTransitionTime (Time)

      lastTransitionTime is the time the condition transitioned from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      message is the human-readable message indicating details about last transition.

    • conditions.reason (string)

      reason is a unique, this should be a short, machine understandable string that gives the reason for condition’s last transition. If it reports “ResizeStarted” that means the underlying persistent volume is being resized.

  • phase (string)

    phase represents the current phase of PersistentVolumeClaim.

  • resizeStatus (string)

    resizeStatus stores status of resize operation. ResizeStatus is not set by default but when expansion is complete resizeStatus is set to empty string by resize controller or kubelet. This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

PersistentVolumeClaimList is a list of PersistentVolumeClaim items.
