#PersistentVolumeClaim [v1]

/kubernetes/{cluster}/api/v1/namespaces/{namespace}/persistentvolumeclaims#

Common Parameters#

  • namespace (in path): string required

    object name and auth scope, such as for teams and projects

  • pretty (in query): string

    If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

get#

list or watch objects of kind PersistentVolumeClaim

Parameters#

  • allowWatchBookmarks (in query): boolean

    allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.

  • continue (in query): string

    The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key".

    This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

  • fieldSelector (in query): string

    A selector to restrict the list of returned objects by their fields. Defaults to everything.

  • labelSelector (in query): string

    A selector to restrict the list of returned objects by their labels. Defaults to everything.

  • limit (in query): integer

    limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

    The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.

  • resourceVersion (in query): string

    resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

    Defaults to unset

  • resourceVersionMatch (in query): string

    resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

    Defaults to unset

  • sendInitialEvents (in query): boolean

    sendInitialEvents=true may be set together with watch=true. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with "k8s.io/initial-events-end": "true" annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched.

    When sendInitialEvents option is set, we require resourceVersionMatch option to also be set. The semantic of the watch request is as following: - resourceVersionMatch = NotOlderThan is interpreted as "data at least as new as the provided resourceVersion" and the bookmark event is send when the state is synced to a resourceVersion at least as fresh as the one provided by the ListOptions. If resourceVersion is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed.

    • resourceVersionMatch set to any other value or unset Invalid error is returned.

    Defaults to true if resourceVersion="" or resourceVersion="0" (for backward compatibility reasons) and to false otherwise.

  • timeoutSeconds (in query): integer

    Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

  • watch (in query): boolean

    Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Response#

  • 200PersistentVolumeClaimList: OK
  • 401: Unauthorized

post#

create a PersistentVolumeClaim

Parameters#

  • dryRun (in query): string

    When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

  • fieldManager (in query): string

    fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.

  • fieldValidation (in query): string

    fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Request Body#

PersistentVolumeClaim

Response#

  • 200PersistentVolumeClaim: OK
  • 201PersistentVolumeClaim: Created
  • 202PersistentVolumeClaim: Accepted
  • 401: Unauthorized

delete#

delete collection of PersistentVolumeClaim

Parameters#

  • continue (in query): string

    The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key".

    This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

  • dryRun (in query): string

    When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

  • fieldSelector (in query): string

    A selector to restrict the list of returned objects by their fields. Defaults to everything.

  • gracePeriodSeconds (in query): integer

    The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

  • ignoreStoreReadErrorWithClusterBreakingPotential (in query): boolean

    if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it

  • labelSelector (in query): string

    A selector to restrict the list of returned objects by their labels. Defaults to everything.

  • limit (in query): integer

    limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

    The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.

  • orphanDependents (in query): boolean

    Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

  • propagationPolicy (in query): string

    Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

  • resourceVersion (in query): string

    resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

    Defaults to unset

  • resourceVersionMatch (in query): string

    resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

    Defaults to unset

  • sendInitialEvents (in query): boolean

    sendInitialEvents=true may be set together with watch=true. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with "k8s.io/initial-events-end": "true" annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched.

    When sendInitialEvents option is set, we require resourceVersionMatch option to also be set. The semantic of the watch request is as following: - resourceVersionMatch = NotOlderThan is interpreted as "data at least as new as the provided resourceVersion" and the bookmark event is send when the state is synced to a resourceVersion at least as fresh as the one provided by the ListOptions. If resourceVersion is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed.

    • resourceVersionMatch set to any other value or unset Invalid error is returned.

    Defaults to true if resourceVersion="" or resourceVersion="0" (for backward compatibility reasons) and to false otherwise.

  • timeoutSeconds (in query): integer

    Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

PersistentVolumeClaimList#

PersistentVolumeClaimList is a list of PersistentVolumeClaim items.

  • apiVersion: string

    APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

  • items: []

    items is a list of persistent volume claims. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

  • kind: string

    Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • metadata:

    Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

PersistentVolumeClaim#

PersistentVolumeClaim is a user's request for and claim to a persistent volume

  • apiVersion: string

    APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

  • kind: string

    Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • metadata:

    Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • spec:

    spec defines the desired characteristics of a volume requested by a pod author. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

  • status:

    status represents the current information/status of a persistent volume claim. Read-only. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

ObjectMeta#

ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.

  • annotations: map[string]string

    Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations

  • creationTimestamp:

    CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.

    Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • deletionGracePeriodSeconds: integer

    Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.

  • deletionTimestamp:

    DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.

    Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • finalizers: []string

    Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.

  • generateName: string

    GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

    If this field is specified and the generated name exists, the server will return a 409.

    Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency

  • generation: integer

    A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.

  • labels: map[string]string

    Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels

  • managedFields: []

    ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.

  • name: string

    Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

  • namespace: string

    Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

    Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces

  • ownerReferences: []

    List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

  • resourceVersion: string

    An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.

    Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency

  • selfLink: string

    Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.

  • uid: string

    UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.

    Populated by the system. Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

Time#

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.

ManagedFieldsEntry#

ManagedFieldsEntry is a workflow-id, a FieldSet and the group version of the resource that the fieldset applies to.

  • apiVersion: string

    APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.

  • fieldsType: string

    FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"

  • fieldsV1:

    FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.

  • manager: string

    Manager is an identifier of the workflow managing these fields.

  • operation: string

    Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.

  • subresource: string

    Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.

  • time:

    Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.

FieldsV1#

FieldsV1 stores a set of fields in a data structure like a Trie, in JSON format.

Each key is either a '.' representing the field itself, and will always map to an empty set, or a string representing a sub-field or item. The string will follow one of these four formats: 'f:', where is the name of a field in a struct, or key in a map 'v:', where is the exact json formatted value of a list item 'i:', where is position of a item in a list 'k:', where is a map of a list item's key fields to their unique values If a key maps to an empty Fields value, the field that key represents is part of the set.

The exact format is defined in sigs.k8s.io/structured-merge-diff

OwnerReference#

OwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field.

  • apiVersion: string

    API version of the referent.

  • blockOwnerDeletion: boolean

    If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.

  • controller: boolean

    If true, this reference points to the managing controller.

  • kind: string

    Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • name: string

    Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

  • uid: string

    UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

PersistentVolumeClaimSpec#

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

  • accessModes: []string

    accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1

  • dataSource:

    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. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.

  • dataSourceRef:

    dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any 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, when namespace isn't specified in dataSourceRef, 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. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three 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.
    • While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
  • resources:

    resources represents the minimum resources the volume should have. If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements that are lower than previous value but must still be higher than capacity recorded in the status field of the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources

  • selector:

    selector is a label query over volumes to consider for binding.

  • storageClassName: string

    storageClassName is the name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1

  • volumeAttributesClassName: string

    volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/ (Beta) Using this field requires the VolumeAttributesClass feature gate to be enabled (off by default).

  • volumeMode: string

    volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec.

    Possible enum values:

    • "Block" means the volume will not be formatted with a filesystem and will remain a raw block device.
    • "Filesystem" means the volume will be or is formatted with a filesystem.
  • volumeName: string

    volumeName is the binding reference to the PersistentVolume backing this claim.

TypedLocalObjectReference#

TypedLocalObjectReference contains enough information to let you locate the typed referenced object inside the same namespace.

  • apiGroup: string

    APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.

  • kind: string

    Kind is the type of resource being referenced

  • name: string

    Name is the name of resource being referenced

TypedObjectReference#

TypedObjectReference contains enough information to let you locate the typed referenced object

  • apiGroup: string

    APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.

  • kind: string

    Kind is the type of resource being referenced

  • name: string

    Name is the name of resource being referenced

  • namespace: string

    Namespace is the namespace of resource being referenced Note that when a namespace is specified, a gateway.networking.k8s.io/ReferenceGrant object is required in the referent namespace to allow that namespace's owner to accept the reference. See the ReferenceGrant documentation for details. (Alpha) This field requires the CrossNamespaceVolumeDataSource feature gate to be enabled.

VolumeResourceRequirements#

VolumeResourceRequirements describes the storage resource requirements for a volume.

  • limits: map[string]Quantity

    Limits describes the maximum amount of compute resources allowed. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

  • requests: map[string]Quantity

    Requests describes the minimum amount of compute resources required. If Requests is omitted for a container, it defaults to Limits if that is explicitly specified, otherwise to an implementation-defined value. Requests cannot exceed Limits. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

Quantity#

Quantity is a fixed-point representation of a number. It provides convenient marshaling/unmarshaling in JSON and YAML, in addition to String() and AsInt64() accessors.

The serialization format is:


	(Note that <suffix> may be empty, from the "" case in <decimalSI>.)

<digit>           ::= 0 | 1 | ... | 9 <digits>          ::= <digit> | <digit><digits> <number>          ::= <digits> | <digits>.<digits> | <digits>. | .<digits> <sign>            ::= "+" | "-" <signedNumber>    ::= <number> | <sign><number> <suffix>          ::= <binarySI> | <decimalExponent> | <decimalSI> <binarySI>        ::= Ki | Mi | Gi | Ti | Pi | Ei

	(International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)

<decimalSI>       ::= m | "" | k | M | G | T | P | E

	(Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.)

<decimalExponent> ::= "e" <signedNumber> | "E" <signedNumber> ```

No matter which of the three exponent forms is used, no quantity may represent a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal places. Numbers larger or more precise will be capped or rounded up. (E.g.: 0.1m will rounded up to 1m.) This may be extended in the future if we require larger or smaller quantities.

When a Quantity is parsed from a string, it will remember the type of suffix it had, and will use the same type again when it is serialized.

Before serializing, Quantity will be put in "canonical form". This means that Exponent/suffix will be adjusted up or down (with a corresponding increase or decrease in Mantissa) such that:

- No precision is lost - No fractional digits will be emitted - The exponent (or suffix) is as large as possible.

The sign will be omitted unless the number is negative.

Examples:

- 1.5 will be serialized as "1500m" - 1.5Gi will be serialized as "1536Mi"

Note that the quantity will NEVER be internally represented by a floating point number. That is the whole point of this exercise.

Non-canonical values will still parse as long as they are well formed, but will be re-emitted in their canonical form. (So always use canonical form, or don't diff.)

This format is intended to make it difficult to use these numbers without writing some sort of special handling code in the hopes that that will cause implementors to also use a fixed point implementation.

LabelSelector#

A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.

  • matchExpressions: []

    matchExpressions is a list of label selector requirements. The requirements are ANDed.

  • matchLabels: map[string]string

    matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.

LabelSelectorRequirement#

A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

  • key: string

    key is the label key that the selector applies to.

  • operator: string

    operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

  • values: []string

    values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.

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

  • allocatedResourceStatuses: map[string]string

    allocatedResourceStatuses stores status of resource being resized for the given PVC. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used.

    ClaimResourceStatus can be in any of following states: - ControllerResizeInProgress: State set when resize controller starts resizing the volume in control-plane. - ControllerResizeFailed: State set when resize has failed in resize controller with a terminal error. - NodeResizePending: State set when resize controller has finished resizing the volume but further resizing of volume is needed on the node. - NodeResizeInProgress: State set when kubelet starts resizing the volume. - NodeResizeFailed: State set when resizing has failed in kubelet with a terminal error. Transient errors don't set NodeResizeFailed. For example: if expanding a PVC for more capacity - this field can be one of the following states: - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed" When this field is not set, it means that no resize operation is in progress for the given PVC.

    A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.

    This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

  • allocatedResources: map[string]Quantity

    allocatedResources tracks the resources allocated to a PVC including its capacity. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used.

    Capacity reported here 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.

    A controller that receives PVC update with previously unknown resourceName should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.

    This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

  • capacity: map[string]Quantity

    capacity represents the actual resources of the underlying volume.

  • conditions: []

    conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'Resizing'.

  • currentVolumeAttributesClassName: string

    currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using. When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim This is a beta field and requires enabling VolumeAttributesClass feature (off by default).

  • modifyVolumeStatus:

    ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted. This is a beta field and requires enabling VolumeAttributesClass feature (off by default).

  • phase: string

    phase represents the current phase of PersistentVolumeClaim.

    Possible enum values:

    • "Bound" used for PersistentVolumeClaims that are bound
    • "Lost" used for PersistentVolumeClaims that lost their underlying PersistentVolume. The claim was bound to a PersistentVolume and this volume does not exist any longer and all data on it was lost.
    • "Pending" used for PersistentVolumeClaims that are not yet bound

PersistentVolumeClaimCondition#

PersistentVolumeClaimCondition contains details about state of pvc

  • lastProbeTime:

    lastProbeTime is the time we probed the condition.

  • lastTransitionTime:

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

  • message: string

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

  • 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 "Resizing" that means the underlying persistent volume is being resized.

  • status: string

    Status is the status of the condition. Can be True, False, Unknown. More info: https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/persistent-volume-claim-v1/#:~:text=state%20of%20pvc-,conditions.status,-(string)%2C%20required

  • type: string

    Type is the type of the condition. More info: https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/persistent-volume-claim-v1/#:~:text=set%20to%20%27ResizeStarted%27.-,PersistentVolumeClaimCondition,-contains%20details%20about

ModifyVolumeStatus#

ModifyVolumeStatus represents the status object of ControllerModifyVolume operation

  • status: string

    status is the status of the ControllerModifyVolume operation. It can be in any of following states:

    • Pending Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing.
    • InProgress InProgress indicates that the volume is being modified.
    • Infeasible Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified. Note: New statuses can be added in the future. Consumers should check for unknown statuses and fail appropriately.

    Possible enum values:

    • "InProgress" InProgress indicates that the volume is being modified
    • "Infeasible" Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified
    • "Pending" Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing
  • targetVolumeAttributesClassName: string

    targetVolumeAttributesClassName is the name of the VolumeAttributesClass the PVC currently being reconciled

ListMeta#

ListMeta describes metadata that synthetic resources must have, including lists and various status objects. A resource may have only one of {ObjectMeta, ListMeta}.

  • continue: string

    continue may be set if the user set a limit on the number of items returned, and indicates that the server has more data available. The value is opaque and may be used to issue another request to the endpoint that served this list to retrieve the next set of available objects. Continuing a consistent list may not be possible if the server configuration has changed or more than a few minutes have passed. The resourceVersion field returned when using this continue value will be identical to the value in the first response, unless you have received this token from an error message.

  • remainingItemCount: integer

    remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.

  • resourceVersion: string

    String that identifies the server's internal version of this object that can be used by clients to determine when objects have changed. Value must be treated as opaque by clients and passed unmodified back to the server. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency

DeleteOptions#

DeleteOptions may be provided when deleting an API object.

  • apiVersion: string

    APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

  • dryRun: []string

    When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

  • gracePeriodSeconds: integer

    The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

  • ignoreStoreReadErrorWithClusterBreakingPotential: boolean

    if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it

  • kind: string

    Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • orphanDependents: boolean

    Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

  • preconditions:

    Must be fulfilled before a deletion is carried out. If not possible, a 409 Conflict status will be returned.

  • propagationPolicy: string

    Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

  • status: string

    Status of the operation. One of: "Success" or "Failure". More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status

StatusDetails#

StatusDetails is a set of additional properties that MAY be set by the server to provide additional information about a response. The Reason field of a Status object defines what attributes will be set. Clients must ignore fields that do not match the defined type of each attribute, and should assume that any attribute may be empty, invalid, or under defined.

  • causes: []

    The Causes array includes more details associated with the StatusReason failure. Not all StatusReasons may provide detailed causes.

StatusCause provides more information about an api.Status failure, including cases when multiple errors are encountered.

  • field: string

    The field of the resource that has caused this error, as named by its JSON serialization. May include dot and postfix notation for nested attributes. Arrays are zero-indexed. Fields may appear more than once in an array of causes due to fields having multiple errors. Optional.

    Examples: "name" - the field "name" on the current resource "items[0].name" - the field "name" on the first array entry in "items"

  • message: string

    A human-readable description of the cause of the error. This field may be presented as-is to a reader.

  • reason: string

    A machine-readable description of the cause of the error. If this value is empty there is no information available.

PersistentVolumeClaim#

PersistentVolumeClaim is a user's request for and claim to a persistent volume

  • apiVersion: string

    APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

  • kind: string

    Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • metadata:

    Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • spec:

    spec defines the desired characteristics of a volume requested by a pod author. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

  • status:

    status represents the current information/status of a persistent volume claim. Read-only. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

ObjectMeta#

ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.

  • annotations: map[string]string

    Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations

  • creationTimestamp:

    CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.

    Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • deletionGracePeriodSeconds: integer

    Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.

  • deletionTimestamp:

    DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.

    Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

  • finalizers: []string

    Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.

  • generateName: string

    GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

    If this field is specified and the generated name exists, the server will return a 409.

    Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency

  • generation: integer

    A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.

  • labels: map[string]string

    Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels

  • managedFields: []

    ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.

  • name: string

    Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

  • namespace: string

    Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

    Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces

  • ownerReferences: []

    List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

  • resourceVersion: string

    An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.

    Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency

  • selfLink: string

    Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.

  • uid: string

    UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.

    Populated by the system. Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

Time#

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.

ManagedFieldsEntry#

ManagedFieldsEntry is a workflow-id, a FieldSet and the group version of the resource that the fieldset applies to.

  • apiVersion: string

    APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.

  • fieldsType: string

    FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"

  • fieldsV1:

    FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.

  • manager: string

    Manager is an identifier of the workflow managing these fields.

  • operation: string

    Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.

  • subresource: string

    Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.

  • time:

    Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.

FieldsV1#

FieldsV1 stores a set of fields in a data structure like a Trie, in JSON format.

Each key is either a '.' representing the field itself, and will always map to an empty set, or a string representing a sub-field or item. The string will follow one of these four formats: 'f:', where is the name of a field in a struct, or key in a map 'v:', where is the exact json formatted value of a list item 'i:', where is position of a item in a list 'k:', where is a map of a list item's key fields to their unique values If a key maps to an empty Fields value, the field that key represents is part of the set.

The exact format is defined in sigs.k8s.io/structured-merge-diff

OwnerReference#

OwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field.

  • apiVersion: string

    API version of the referent.

  • blockOwnerDeletion: boolean

    If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.

  • controller: boolean

    If true, this reference points to the managing controller.

  • kind: string

    Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • name: string

    Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

  • uid: string

    UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

PersistentVolumeClaimSpec#

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

  • accessModes: []string

    accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1

  • dataSource:

    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. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.

  • dataSourceRef:

    dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any 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, when namespace isn't specified in dataSourceRef, 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. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three 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.
    • While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
  • resources:

    resources represents the minimum resources the volume should have. If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements that are lower than previous value but must still be higher than capacity recorded in the status field of the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources

  • selector:

    selector is a label query over volumes to consider for binding.

  • storageClassName: string

    storageClassName is the name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1

  • volumeAttributesClassName: string

    volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/ (Beta) Using this field requires the VolumeAttributesClass feature gate to be enabled (off by default).

  • volumeMode: string

    volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec.

    Possible enum values:

    • "Block" means the volume will not be formatted with a filesystem and will remain a raw block device.
    • "Filesystem" means the volume will be or is formatted with a filesystem.
  • volumeName: string

    volumeName is the binding reference to the PersistentVolume backing this claim.

TypedLocalObjectReference#

TypedLocalObjectReference contains enough information to let you locate the typed referenced object inside the same namespace.

  • apiGroup: string

    APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.

  • kind: string

    Kind is the type of resource being referenced

  • name: string

    Name is the name of resource being referenced

  • apiGroup: string

    APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.

  • kind: string

    Kind is the type of resource being referenced

  • name: string

    Name is the name of resource being referenced

  • namespace: string

    Namespace is the namespace of resource being referenced Note that when a namespace is specified, a gateway.networking.k8s.io/ReferenceGrant object is required in the referent namespace to allow that namespace's owner to accept the reference. See the ReferenceGrant documentation for details. (Alpha) This field requires the CrossNamespaceVolumeDataSource feature gate to be enabled.

VolumeResourceRequirements#

VolumeResourceRequirements describes the storage resource requirements for a volume.

  • limits: map[string]Quantity

    Limits describes the maximum amount of compute resources allowed. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

  • requests: map[string]Quantity

    Requests describes the minimum amount of compute resources required. If Requests is omitted for a container, it defaults to Limits if that is explicitly specified, otherwise to an implementation-defined value. Requests cannot exceed Limits. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

Quantity#

Quantity is a fixed-point representation of a number. It provides convenient marshaling/unmarshaling in JSON and YAML, in addition to String() and AsInt64() accessors.

The serialization format is:


	(Note that <suffix> may be empty, from the "" case in <decimalSI>.)

<digit>           ::= 0 | 1 | ... | 9 <digits>          ::= <digit> | <digit><digits> <number>          ::= <digits> | <digits>.<digits> | <digits>. | .<digits> <sign>            ::= "+" | "-" <signedNumber>    ::= <number> | <sign><number> <suffix>          ::= <binarySI> | <decimalExponent> | <decimalSI> <binarySI>        ::= Ki | Mi | Gi | Ti | Pi | Ei

	(International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)

<decimalSI>       ::= m | "" | k | M | G | T | P | E

	(Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.)

<decimalExponent> ::= "e" <signedNumber> | "E" <signedNumber> ```

No matter which of the three exponent forms is used, no quantity may represent a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal places. Numbers larger or more precise will be capped or rounded up. (E.g.: 0.1m will rounded up to 1m.) This may be extended in the future if we require larger or smaller quantities.

When a Quantity is parsed from a string, it will remember the type of suffix it had, and will use the same type again when it is serialized.

Before serializing, Quantity will be put in "canonical form". This means that Exponent/suffix will be adjusted up or down (with a corresponding increase or decrease in Mantissa) such that:

- No precision is lost - No fractional digits will be emitted - The exponent (or suffix) is as large as possible.

The sign will be omitted unless the number is negative.

Examples:

- 1.5 will be serialized as "1500m" - 1.5Gi will be serialized as "1536Mi"

Note that the quantity will NEVER be internally represented by a floating point number. That is the whole point of this exercise.

Non-canonical values will still parse as long as they are well formed, but will be re-emitted in their canonical form. (So always use canonical form, or don't diff.)

This format is intended to make it difficult to use these numbers without writing some sort of special handling code in the hopes that that will cause implementors to also use a fixed point implementation.

LabelSelector#

A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.

  • matchExpressions: []

    matchExpressions is a list of label selector requirements. The requirements are ANDed.

  • matchLabels: map[string]string

    matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.

LabelSelectorRequirement#

A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

  • key: string

    key is the label key that the selector applies to.

  • operator: string

    operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

  • values: []string

    values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.

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

  • allocatedResourceStatuses: map[string]string

    allocatedResourceStatuses stores status of resource being resized for the given PVC. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used.

    ClaimResourceStatus can be in any of following states: - ControllerResizeInProgress: State set when resize controller starts resizing the volume in control-plane. - ControllerResizeFailed: State set when resize has failed in resize controller with a terminal error. - NodeResizePending: State set when resize controller has finished resizing the volume but further resizing of volume is needed on the node. - NodeResizeInProgress: State set when kubelet starts resizing the volume. - NodeResizeFailed: State set when resizing has failed in kubelet with a terminal error. Transient errors don't set NodeResizeFailed. For example: if expanding a PVC for more capacity - this field can be one of the following states: - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed" When this field is not set, it means that no resize operation is in progress for the given PVC.

    A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.

    This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

  • allocatedResources: map[string]Quantity

    allocatedResources tracks the resources allocated to a PVC including its capacity. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used.

    Capacity reported here 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.

    A controller that receives PVC update with previously unknown resourceName should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.

    This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.

  • capacity: map[string]Quantity

    capacity represents the actual resources of the underlying volume.

  • conditions: []

    conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'Resizing'.

  • currentVolumeAttributesClassName: string

    currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using. When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim This is a beta field and requires enabling VolumeAttributesClass feature (off by default).

  • modifyVolumeStatus:

    ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted. This is a beta field and requires enabling VolumeAttributesClass feature (off by default).

  • phase: string

    phase represents the current phase of PersistentVolumeClaim.

    Possible enum values:

    • "Bound" used for PersistentVolumeClaims that are bound
    • "Lost" used for PersistentVolumeClaims that lost their underlying PersistentVolume. The claim was bound to a PersistentVolume and this volume does not exist any longer and all data on it was lost.
    • "Pending" used for PersistentVolumeClaims that are not yet bound

PersistentVolumeClaimCondition#

PersistentVolumeClaimCondition contains details about state of pvc

  • lastProbeTime:

    lastProbeTime is the time we probed the condition.

  • lastTransitionTime:

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

  • message: string

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

  • 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 "Resizing" that means the underlying persistent volume is being resized.

  • status: string

    Status is the status of the condition. Can be True, False, Unknown. More info: https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/persistent-volume-claim-v1/#:~:text=state%20of%20pvc-,conditions.status,-(string)%2C%20required

  • type: string

    Type is the type of the condition. More info: https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/persistent-volume-claim-v1/#:~:text=set%20to%20%27ResizeStarted%27.-,PersistentVolumeClaimCondition,-contains%20details%20about

ModifyVolumeStatus#

ModifyVolumeStatus represents the status object of ControllerModifyVolume operation

  • status: string

    status is the status of the ControllerModifyVolume operation. It can be in any of following states:

    • Pending Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing.
    • InProgress InProgress indicates that the volume is being modified.
    • Infeasible Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified. Note: New statuses can be added in the future. Consumers should check for unknown statuses and fail appropriately.

    Possible enum values:

    • "InProgress" InProgress indicates that the volume is being modified
    • "Infeasible" Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified
    • "Pending" Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing
  • targetVolumeAttributesClassName: string

    targetVolumeAttributesClassName is the name of the VolumeAttributesClass the PVC currently being reconciled

DeleteOptions#

DeleteOptions may be provided when deleting an API object.

  • apiVersion: string

    APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

  • dryRun: []string

    When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

  • gracePeriodSeconds: integer

    The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

  • ignoreStoreReadErrorWithClusterBreakingPotential: boolean

    if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it

  • kind: string

    Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

  • orphanDependents: boolean

    Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

  • preconditions:

    Must be fulfilled before a deletion is carried out. If not possible, a 409 Conflict status will be returned.

  • propagationPolicy: string

    Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Preconditions#

Preconditions must be fulfilled before an operation (update, delete, etc.) is carried out.

  • resourceVersion: string

    Specifies the target ResourceVersion

  • uid: string

    Specifies the target UID.
