Storage APIs


OpenShift Container Platform 4.13

Reference guide for storage APIs

Red Hat OpenShift Documentation Team

Abstract

This document describes the OpenShift Container Platform storage API objects and their detailed specifications.

Chapter 1. Storage APIs

1.1. CSIDriver [storage.k8s.io/v1]

Description
CSIDriver captures information about a Container Storage Interface (CSI) volume driver deployed on the cluster. Kubernetes attach detach controller uses this object to determine whether attach is required. Kubelet uses this object to determine whether pod information needs to be passed on mount. CSIDriver objects are non-namespaced.
Type
object

1.2. CSINode [storage.k8s.io/v1]

Description
CSINode holds information about all CSI drivers installed on a node. CSI drivers do not need to create the CSINode object directly. As long as they use the node-driver-registrar sidecar container, the kubelet will automatically populate the CSINode object for the CSI driver as part of kubelet plugin registration. CSINode has the same name as a node. If the object is missing, it means either there are no CSI Drivers available on the node, or the Kubelet version is low enough that it doesn’t create this object. CSINode has an OwnerReference that points to the corresponding node object.
Type
object

1.3. CSIStorageCapacity [storage.k8s.io/v1]

Description

CSIStorageCapacity stores the result of one CSI GetCapacity call. For a given StorageClass, this describes the available capacity in a particular topology segment. This can be used when considering where to instantiate new PersistentVolumes.

For example this can express things like: - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1" - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"

The following three cases all imply that no capacity is available for a certain combination: - no object exists with suitable topology and storage class name - such an object exists, but the capacity is unset - such an object exists, but the capacity is zero

The producer of these objects can decide which approach is more suitable.

They are consumed by the kube-scheduler when a CSI driver opts into capacity-aware scheduling with CSIDriverSpec.StorageCapacity. The scheduler compares the MaximumVolumeSize against the requested size of pending volumes to filter out unsuitable nodes. If MaximumVolumeSize is unset, it falls back to a comparison against the less precise Capacity. If that is also unset, the scheduler assumes that capacity is insufficient and tries some other node.

Type
object

1.4. PersistentVolume [v1]

Description
PersistentVolume (PV) is a storage resource provisioned by an administrator. It is analogous to a node. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes
Type
object

1.5. PersistentVolumeClaim [v1]

Description
PersistentVolumeClaim is a user’s request for and claim to a persistent volume
Type
object

1.6. StorageClass [storage.k8s.io/v1]

Description

StorageClass describes the parameters for a class of storage for which PersistentVolumes can be dynamically provisioned.

StorageClasses are non-namespaced; the name of the storage class according to etcd is in ObjectMeta.Name.

Type
object

1.7. StorageState [migration.k8s.io/v1alpha1]

Description
The state of the storage of a specific resource.
Type
object

1.8. StorageVersionMigration [migration.k8s.io/v1alpha1]

Description
StorageVersionMigration represents a migration of stored data to the latest storage version.
Type
object

1.9. VolumeAttachment [storage.k8s.io/v1]

Description

VolumeAttachment captures the intent to attach or detach the specified volume to/from the specified node.

VolumeAttachment objects are non-namespaced.

Type
object

1.10. VolumeSnapshot [snapshot.storage.k8s.io/v1]

Description
VolumeSnapshot is a user’s request for either creating a point-in-time snapshot of a persistent volume, or binding to a pre-existing snapshot.
Type
object

1.11. VolumeSnapshotClass [snapshot.storage.k8s.io/v1]

Description
VolumeSnapshotClass specifies parameters that a underlying storage system uses when creating a volume snapshot. A specific VolumeSnapshotClass is used by specifying its name in a VolumeSnapshot object. VolumeSnapshotClasses are non-namespaced
Type
object

1.12. VolumeSnapshotContent [snapshot.storage.k8s.io/v1]

Description
VolumeSnapshotContent represents the actual "on-disk" snapshot object in the underlying storage system
Type
object

Chapter 2. CSIDriver [storage.k8s.io/v1]

Description
CSIDriver captures information about a Container Storage Interface (CSI) volume driver deployed on the cluster. Kubernetes attach detach controller uses this object to determine whether attach is required. Kubelet uses this object to determine whether pod information needs to be passed on mount. CSIDriver objects are non-namespaced.
Type
object
Required
  • spec

2.1. Specification

PropertyTypeDescription

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

ObjectMeta

Standard object metadata. metadata.Name indicates the name of the CSI driver that this object refers to; it MUST be the same name returned by the CSI GetPluginName() call for that driver. The driver name must be 63 characters or less, beginning and ending with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), dots (.), and alphanumerics between. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

CSIDriverSpec is the specification of a CSIDriver.

2.1.1. .spec

Description
CSIDriverSpec is the specification of a CSIDriver.
Type
object
PropertyTypeDescription

attachRequired

boolean

attachRequired indicates this CSI volume driver requires an attach operation (because it implements the CSI ControllerPublishVolume() method), and that the Kubernetes attach detach controller should call the attach volume interface which checks the volumeattachment status and waits until the volume is attached before proceeding to mounting. The CSI external-attacher coordinates with CSI volume driver and updates the volumeattachment status when the attach operation is complete. If the CSIDriverRegistry feature gate is enabled and the value is specified to false, the attach operation will be skipped. Otherwise the attach operation will be called.

This field is immutable.

fsGroupPolicy

string

Defines if the underlying volume supports changing ownership and permission of the volume before being mounted. Refer to the specific FSGroupPolicy values for additional details.

This field is immutable.

Defaults to ReadWriteOnceWithFSType, which will examine each volume to determine if Kubernetes should modify ownership and permissions of the volume. With the default policy the defined fsGroup will only be applied if a fstype is defined and the volume’s access mode contains ReadWriteOnce.

podInfoOnMount

boolean

If set to true, podInfoOnMount indicates this CSI volume driver requires additional pod information (like podName, podUID, etc.) during mount operations. If set to false, pod information will not be passed on mount. Default is false. The CSI driver specifies podInfoOnMount as part of driver deployment. If true, Kubelet will pass pod information as VolumeContext in the CSI NodePublishVolume() calls. The CSI driver is responsible for parsing and validating the information passed in as VolumeContext. The following VolumeConext will be passed if podInfoOnMount is set to true. This list might grow, but the prefix will be used. "csi.storage.k8s.io/pod.name": pod.Name "csi.storage.k8s.io/pod.namespace": pod.Namespace "csi.storage.k8s.io/pod.uid": string(pod.UID) "csi.storage.k8s.io/ephemeral": "true" if the volume is an ephemeral inline volume defined by a CSIVolumeSource, otherwise "false"

"csi.storage.k8s.io/ephemeral" is a new feature in Kubernetes 1.16. It is only required for drivers which support both the "Persistent" and "Ephemeral" VolumeLifecycleMode. Other drivers can leave pod info disabled and/or ignore this field. As Kubernetes 1.15 doesn’t support this field, drivers can only support one mode when deployed on such a cluster and the deployment determines which mode that is, for example via a command line parameter of the driver.

This field is immutable.

requiresRepublish

boolean

RequiresRepublish indicates the CSI driver wants NodePublishVolume being periodically called to reflect any possible change in the mounted volume. This field defaults to false.

Note: After a successful initial NodePublishVolume call, subsequent calls to NodePublishVolume should only update the contents of the volume. New mount points will not be seen by a running container.

seLinuxMount

boolean

SELinuxMount specifies if the CSI driver supports "-o context" mount option.

When "true", the CSI driver must ensure that all volumes provided by this CSI driver can be mounted separately with different -o context options. This is typical for storage backends that provide volumes as filesystems on block devices or as independent shared volumes. Kubernetes will call NodeStage / NodePublish with "-o context=xyz" mount option when mounting a ReadWriteOncePod volume used in Pod that has explicitly set SELinux context. In the future, it may be expanded to other volume AccessModes. In any case, Kubernetes will ensure that the volume is mounted only with a single SELinux context.

When "false", Kubernetes won’t pass any special SELinux mount options to the driver. This is typical for volumes that represent subdirectories of a bigger shared filesystem.

Default is "false".

storageCapacity

boolean

If set to true, storageCapacity indicates that the CSI volume driver wants pod scheduling to consider the storage capacity that the driver deployment will report by creating CSIStorageCapacity objects with capacity information.

The check can be enabled immediately when deploying a driver. In that case, provisioning new volumes with late binding will pause until the driver deployment has published some suitable CSIStorageCapacity object.

Alternatively, the driver can be deployed with the field unset or false and it can be flipped later when storage capacity information has been published.

This field was immutable in Kubernetes ⇐ 1.22 and now is mutable.

tokenRequests

array

TokenRequests indicates the CSI driver needs pods' service account tokens it is mounting volume for to do necessary authentication. Kubelet will pass the tokens in VolumeContext in the CSI NodePublishVolume calls. The CSI driver should parse and validate the following VolumeContext: "csi.storage.k8s.io/serviceAccount.tokens": { "<audience>": { "token": <token>, "expirationTimestamp": <expiration timestamp in RFC3339>, }, …​ }

Note: Audience in each TokenRequest should be different and at most one token is empty string. To receive a new token after expiry, RequiresRepublish can be used to trigger NodePublishVolume periodically.

tokenRequests[]

object

TokenRequest contains parameters of a service account token.

volumeLifecycleModes

array (string)

volumeLifecycleModes defines what kind of volumes this CSI volume driver supports. The default if the list is empty is "Persistent", which is the usage defined by the CSI specification and implemented in Kubernetes via the usual PV/PVC mechanism. The other mode is "Ephemeral". In this mode, volumes are defined inline inside the pod spec with CSIVolumeSource and their lifecycle is tied to the lifecycle of that pod. A driver has to be aware of this because it is only going to get a NodePublishVolume call for such a volume. For more information about implementing this mode, see https://kubernetes-csi.github.io/docs/ephemeral-local-volumes.html A driver can support one or more of these modes and more modes may be added in the future. This field is beta.

This field is immutable.

2.1.2. .spec.tokenRequests

Description

TokenRequests indicates the CSI driver needs pods' service account tokens it is mounting volume for to do necessary authentication. Kubelet will pass the tokens in VolumeContext in the CSI NodePublishVolume calls. The CSI driver should parse and validate the following VolumeContext: "csi.storage.k8s.io/serviceAccount.tokens": { "<audience>": { "token": <token>, "expirationTimestamp": <expiration timestamp in RFC3339>, }, …​ }

Note: Audience in each TokenRequest should be different and at most one token is empty string. To receive a new token after expiry, RequiresRepublish can be used to trigger NodePublishVolume periodically.

Table 2.2. Query parameters
ParameterTypeDescription

continue

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

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

string

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

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.

labelSelector

string

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

limit

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

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

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

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

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

timeoutSeconds

integer

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

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

This is the default behavior prior to v1.23 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

Table 2.24. Global path parameters
ParameterTypeDescription

name

string

name of the CSIDriver

Table 2.25. Global query parameters
ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

integer

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

watch

boolean

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

Chapter 3. CSINode [storage.k8s.io/v1]

Description
CSINode holds information about all CSI drivers installed on a node. CSI drivers do not need to create the CSINode object directly. As long as they use the node-driver-registrar sidecar container, the kubelet will automatically populate the CSINode object for the CSI driver as part of kubelet plugin registration. CSINode has the same name as a node. If the object is missing, it means either there are no CSI Drivers available on the node, or the Kubelet version is low enough that it doesn’t create this object. CSINode has an OwnerReference that points to the corresponding node 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

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

PropertyTypeDescription

allocatable

object

VolumeNodeResources is a set of resource limits for scheduling of volumes.

name

string

This is the name of the CSI driver that this object refers to. This MUST be the same name returned by the CSI GetPluginName() call for that driver.

nodeID

string

nodeID of the node from the driver point of view. This field enables Kubernetes to communicate with storage systems that do not share the same nomenclature for nodes. For example, Kubernetes may refer to a given node as "node1", but the storage system may refer to the same node as "nodeA". When Kubernetes issues a command to the storage system to attach a volume to a specific node, it can use this field to refer to the node name using the ID that the storage system will understand, e.g. "nodeA" instead of "node1". This field is required.

topologyKeys

array (string)

topologyKeys is the list of keys supported by the driver. When a driver is initialized on a cluster, it provides a set of topology keys that it understands (e.g. "company.com/zone", "company.com/region"). When a driver is initialized on a node, it provides the same topology keys along with values. Kubelet will expose these topology keys as labels on its own node object. When Kubernetes does topology aware provisioning, it can use this list to determine which labels it should retrieve from the node object and pass back to the driver. It is possible for different nodes to use different topology keys. This can be empty if driver does not support topology.

3.1.4. .spec.drivers[].allocatable

Description
VolumeNodeResources is a set of resource limits for scheduling of volumes.
Type
object
PropertyTypeDescription

count

integer

Maximum number of unique volumes managed by the CSI driver that can be used on a node. A volume that is both attached and mounted on a node is considered to be used once, not twice. The same rule applies for a unique volume that is shared among multiple pods on the same node. If this field is not specified, then the supported number of volumes on this node is unbounded.

fieldManager

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

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

integer

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

boolean

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

Chapter 4. CSIStorageCapacity [storage.k8s.io/v1]

Description

CSIStorageCapacity stores the result of one CSI GetCapacity call. For a given StorageClass, this describes the available capacity in a particular topology segment. This can be used when considering where to instantiate new PersistentVolumes.

For example this can express things like: - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1" - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"

The following three cases all imply that no capacity is available for a certain combination: - no object exists with suitable topology and storage class name - such an object exists, but the capacity is unset - such an object exists, but the capacity is zero

The producer of these objects can decide which approach is more suitable.

They are consumed by the kube-scheduler when a CSI driver opts into capacity-aware scheduling with CSIDriverSpec.StorageCapacity. The scheduler compares the MaximumVolumeSize against the requested size of pending volumes to filter out unsuitable nodes. If MaximumVolumeSize is unset, it falls back to a comparison against the less precise Capacity. If that is also unset, the scheduler assumes that capacity is insufficient and tries some other node.

Type
object
Required
  • storageClassName

4.1. Specification

PropertyTypeDescription

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

capacity

Quantity

Capacity is the value reported by the CSI driver in its GetCapacityResponse for a GetCapacityRequest with topology and parameters that match the previous fields.

The semantic is currently (CSI spec 1.2) defined as: The available capacity, in bytes, of the storage that can be used to provision volumes. If not set, that information is currently unavailable.

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

maximumVolumeSize

Quantity

MaximumVolumeSize is the value reported by the CSI driver in its GetCapacityResponse for a GetCapacityRequest with topology and parameters that match the previous fields.

This is defined since CSI spec 1.4.0 as the largest size that may be used in a CreateVolumeRequest.capacity_range.required_bytes field to create a volume with the same parameters as those in GetCapacityRequest. The corresponding value in the Kubernetes API is ResourceRequirements.Requests in a volume claim.

metadata

ObjectMeta

Standard object’s metadata. The name has no particular meaning. It must be be a DNS subdomain (dots allowed, 253 characters). To ensure that there are no conflicts with other CSI drivers on the cluster, the recommendation is to use csisc-<uuid>, a generated name, or a reverse-domain name which ends with the unique CSI driver name.

Objects are namespaced.

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

nodeTopology

LabelSelector

NodeTopology defines which nodes have access to the storage for which capacity was reported. If not set, the storage is not accessible from any node in the cluster. If empty, the storage is accessible from all nodes. This field is immutable.

storageClassName

string

The name of the StorageClass that the reported capacity applies to. It must meet the same requirements as the name of a StorageClass object (non-empty, DNS subdomain). If that object no longer exists, the CSIStorageCapacity object is obsolete and should be removed by its creator. This field is immutable.

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.

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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

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.

ParameterTypeDescription

pretty

string

If 'true', then the output is pretty printed.

HTTP method
DELETE
Description
delete collection of PersistentVolume
Table 5.2. Query parameters
ParameterTypeDescription

continue

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

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

string

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

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.

labelSelector

string

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

limit

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

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

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

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

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

timeoutSeconds

integer

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

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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

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

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.

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

fieldManager

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

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

5.2.2. /api/v1/watch/persistentvolumes

Table 5.10. Global query parameters
ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

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.

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.

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.

dataSource

object

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

dataSourceRef

object

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.

6.2.1. /api/v1/persistentvolumeclaims

Table 6.1. Global query parameters
ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

integer

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

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

integer

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

fieldManager

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.

Chapter 7. StorageClass [storage.k8s.io/v1]

Description

StorageClass describes the parameters for a class of storage for which PersistentVolumes can be dynamically provisioned.

StorageClasses are non-namespaced; the name of the storage class according to etcd is in ObjectMeta.Name.

Type
object
Required
  • provisioner

7.1. Specification

PropertyTypeDescription

allowVolumeExpansion

boolean

AllowVolumeExpansion shows whether the storage class allow volume expand

allowedTopologies

array (TopologySelectorTerm)

Restrict the node topologies where volumes can be dynamically provisioned. Each volume plugin defines its own supported topology specifications. An empty TopologySelectorTerm list means there is no topology restriction. This field is only honored by servers that enable the VolumeScheduling feature.

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

ObjectMeta

Dynamically provisioned PersistentVolumes of this storage class are created with these mountOptions, e.g. ["ro", "soft"]. Not validated - mount of the PVs will simply fail if one is invalid.

parameters

object (string)

Parameters holds the parameters for the provisioner that should create volumes of this storage class.

provisioner

string

Provisioner indicates the type of the provisioner.

reclaimPolicy

string

Dynamically provisioned PersistentVolumes of this storage class are created with this reclaimPolicy. Defaults to Delete.

Table 7.2. Query parameters
ParameterTypeDescription

continue

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

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

string

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

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.

labelSelector

string

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

limit

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

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

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

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

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

timeoutSeconds

integer

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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

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

timeoutSeconds

integer

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

lastHeartbeatTime

string

LastHeartbeatTime is the last time the storage migration triggering controller checks the storage version hash of this resource in the discovery document and updates this field.

persistedStorageVersionHashes

array (string)

The hash values of storage versions that persisted instances of spec.resource might still be encoded in. "Unknown" is a valid value in the list, and is the default value. It is not safe to upgrade or downgrade to an apiserver binary that does not support all versions listed in this field, or if "Unknown" is listed. Once the storage version migration for this resource has completed, the value of this field is refined to only contain the currentStorageVersionHash. Once the apiserver has changed the storage version, the new storage version is appended to the list.

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

string

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

labelSelector

string

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

limit

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

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

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

timeoutSeconds

integer

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

watch

boolean

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

If this is not a watch, this field is ignored.

continue

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.

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.

continue

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

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

string

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

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.

labelSelector

string

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

limit

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

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

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

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

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

timeoutSeconds

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

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

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

timeoutSeconds

integer

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

watch

boolean

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

fieldManager

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

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.

Table 10.10. Global query parameters
ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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

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

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.

Required
  • source
PropertyTypeDescription

source

object

source specifies where a snapshot will be created from. This field is immutable after creation. Required.

volumeSnapshotClassName

string

VolumeSnapshotClassName is the name of the VolumeSnapshotClass requested by the VolumeSnapshot. VolumeSnapshotClassName may be left nil to indicate that the default SnapshotClass should be used. A given cluster may have multiple default Volume SnapshotClasses: one default per CSI Driver. If a VolumeSnapshot does not specify a SnapshotClass, VolumeSnapshotSource will be checked to figure out what the associated CSI Driver is, and the default VolumeSnapshotClass associated with that CSI Driver will be used. If more than one VolumeSnapshotClass exist for a given CSI Driver and more than one have been marked as default, CreateSnapshot will fail and generate an event. Empty string is not allowed for this field.

11.1.2. .spec.source

Description
source specifies where a snapshot will be created from. This field is immutable after creation. Required.
Type
object
PropertyTypeDescription

persistentVolumeClaimName

string

persistentVolumeClaimName specifies the name of the PersistentVolumeClaim object representing the volume from which a snapshot should be created. This PVC is assumed to be in the same namespace as the VolumeSnapshot object. This field should be set if the snapshot does not exists, and needs to be created. This field is immutable.

volumeSnapshotContentName

string

volumeSnapshotContentName specifies the name of a pre-existing VolumeSnapshotContent object representing an existing volume snapshot. This field should be set if the snapshot already exists and only needs a representation in Kubernetes. This field is immutable.

11.1.3. .status

Description
status represents the current information of a snapshot. Consumers must verify binding between VolumeSnapshot and VolumeSnapshotContent objects is successful (by validating that both VolumeSnapshot and VolumeSnapshotContent point at each other) before using this object.
Type
object
PropertyTypeDescription

boundVolumeSnapshotContentName

string

boundVolumeSnapshotContentName is the name of the VolumeSnapshotContent object to which this VolumeSnapshot object intends to bind to. If not specified, it indicates that the VolumeSnapshot object has not been successfully bound to a VolumeSnapshotContent object yet. NOTE: To avoid possible security issues, consumers must verify binding between VolumeSnapshot and VolumeSnapshotContent objects is successful (by validating that both VolumeSnapshot and VolumeSnapshotContent point at each other) before using this object.

creationTime

string

creationTime is the timestamp when the point-in-time snapshot is taken by the underlying storage system. In dynamic snapshot creation case, this field will be filled in by the snapshot controller with the "creation_time" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "creation_time" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it. If not specified, it may indicate that the creation time of the snapshot is unknown.

error

object

error is the last observed error during snapshot creation, if any. This field could be helpful to upper level controllers(i.e., application controller) to decide whether they should continue on waiting for the snapshot to be created based on the type of error reported. The snapshot controller will keep retrying when an error occurs during the snapshot creation. Upon success, this error field will be cleared.

readyToUse

boolean

readyToUse indicates if the snapshot is ready to be used to restore a volume. In dynamic snapshot creation case, this field will be filled in by the snapshot controller with the "ready_to_use" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "ready_to_use" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it, otherwise, this field will be set to "True". If not specified, it means the readiness of a snapshot is unknown.

restoreSize

integer-or-string

restoreSize represents the minimum size of volume required to create a volume from this snapshot. In dynamic snapshot creation case, this field will be filled in by the snapshot controller with the "size_bytes" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "size_bytes" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it. When restoring a volume from this snapshot, the size of the volume MUST NOT be smaller than the restoreSize if it is specified, otherwise the restoration will fail. If not specified, it indicates that the size is unknown.

11.1.4. .status.error

Description
error is the last observed error during snapshot creation, if any. This field could be helpful to upper level controllers(i.e., application controller) to decide whether they should continue on waiting for the snapshot to be created based on the type of error reported. The snapshot controller will keep retrying when an error occurs during the snapshot creation. Upon success, this error field will be cleared.
Type
object
PropertyTypeDescription

message

string

message is a string detailing the encountered error during snapshot creation if specified. NOTE: message may be logged, and it should not contain sensitive information.

time

string

time is the timestamp when the error was encountered.

11.2.1. /apis/snapshot.storage.k8s.io/v1/volumesnapshots

Table 11.1. Global query parameters
ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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.

pretty

string

If 'true', then the output is pretty printed.

resourceVersion

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.

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

timeoutSeconds

allowWatchBookmarks

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

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.

Chapter 12. VolumeSnapshotClass [snapshot.storage.k8s.io/v1]

Description
VolumeSnapshotClass specifies parameters that a underlying storage system uses when creating a volume snapshot. A specific VolumeSnapshotClass is used by specifying its name in a VolumeSnapshot object. VolumeSnapshotClasses are non-namespaced
Type
object
Required
  • deletionPolicy
  • driver

12.1. Specification

PropertyTypeDescription

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

deletionPolicy

string

deletionPolicy determines whether a VolumeSnapshotContent created through the VolumeSnapshotClass should be deleted when its bound VolumeSnapshot is deleted. Supported values are "Retain" and "Delete". "Retain" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are kept. "Delete" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are deleted. Required.

driver

string

driver is the name of the storage driver that handles this VolumeSnapshotClass. Required.

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

ObjectMeta

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

parameters

object (string)

parameters is a key-value map with storage driver specific parameters for creating snapshots. These values are opaque to Kubernetes.

12.2. API endpoints

The following API endpoints are available:

  • /apis/snapshot.storage.k8s.io/v1/volumesnapshotclasses

    • DELETE: delete collection of VolumeSnapshotClass
    • GET: list objects of kind VolumeSnapshotClass
    • POST: create a VolumeSnapshotClass
  • /apis/snapshot.storage.k8s.io/v1/volumesnapshotclasses/{name}

    • DELETE: delete a VolumeSnapshotClass
    • GET: read the specified VolumeSnapshotClass
    • PATCH: partially update the specified VolumeSnapshotClass
    • PUT: replace the specified VolumeSnapshotClass

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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

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

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

timeoutSeconds

integer

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

watch

boolean

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

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.

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

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

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

timeoutSeconds

integer

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

watch

boolean

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

  • deletionPolicy
  • driver
  • source
  • volumeSnapshotRef
PropertyTypeDescription

deletionPolicy

string

deletionPolicy determines whether this VolumeSnapshotContent and its physical snapshot on the underlying storage system should be deleted when its bound VolumeSnapshot is deleted. Supported values are "Retain" and "Delete". "Retain" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are kept. "Delete" means that the VolumeSnapshotContent and its physical snapshot on underlying storage system are deleted. For dynamically provisioned snapshots, this field will automatically be filled in by the CSI snapshotter sidecar with the "DeletionPolicy" field defined in the corresponding VolumeSnapshotClass. For pre-existing snapshots, users MUST specify this field when creating the VolumeSnapshotContent object. Required.

driver

string

driver is the name of the CSI driver used to create the physical snapshot on the underlying storage system. This MUST be the same as the name returned by the CSI GetPluginName() call for that driver. Required.

source

object

source specifies whether the snapshot is (or should be) dynamically provisioned or already exists, and just requires a Kubernetes object representation. This field is immutable after creation. Required.

sourceVolumeMode

string

SourceVolumeMode is the mode of the volume whose snapshot is taken. Can be either “Filesystem” or “Block”. If not specified, it indicates the source volume’s mode is unknown. This field is immutable. This field is an alpha field.

volumeSnapshotClassName

string

name of the VolumeSnapshotClass from which this snapshot was (or will be) created. Note that after provisioning, the VolumeSnapshotClass may be deleted or recreated with different set of values, and as such, should not be referenced post-snapshot creation.

volumeSnapshotRef

object

volumeSnapshotRef specifies the VolumeSnapshot object to which this VolumeSnapshotContent object is bound. VolumeSnapshot.Spec.VolumeSnapshotContentName field must reference to this VolumeSnapshotContent’s name for the bidirectional binding to be valid. For a pre-existing VolumeSnapshotContent object, name and namespace of the VolumeSnapshot object MUST be provided for binding to happen. This field is immutable after creation. Required.

13.1.2. .spec.source

Description
source specifies whether the snapshot is (or should be) dynamically provisioned or already exists, and just requires a Kubernetes object representation. This field is immutable after creation. Required.
Type
object
PropertyTypeDescription

snapshotHandle

string

snapshotHandle specifies the CSI "snapshot_id" of a pre-existing snapshot on the underlying storage system for which a Kubernetes object representation was (or should be) created. This field is immutable.

volumeHandle

string

volumeHandle specifies the CSI "volume_id" of the volume from which a snapshot should be dynamically taken from. This field is immutable.

13.1.3. .spec.volumeSnapshotRef

Description
volumeSnapshotRef specifies the VolumeSnapshot object to which this VolumeSnapshotContent object is bound. VolumeSnapshot.Spec.VolumeSnapshotContentName field must reference to this VolumeSnapshotContent’s name for the bidirectional binding to be valid. For a pre-existing VolumeSnapshotContent object, name and namespace of the VolumeSnapshot object MUST be provided for binding to happen. This field is immutable after creation. Required.
Type
object
PropertyTypeDescription

apiVersion

string

API version of the referent.

fieldPath

string

If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. TODO: this design is not final and this field is subject to change in the future.

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

Description
status represents the current information of a snapshot.
Type
object
PropertyTypeDescription

creationTime

integer

creationTime is the timestamp when the point-in-time snapshot is taken by the underlying storage system. In dynamic snapshot creation case, this field will be filled in by the CSI snapshotter sidecar with the "creation_time" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "creation_time" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it. If not specified, it indicates the creation time is unknown. The format of this field is a Unix nanoseconds time encoded as an int64. On Unix, the command date +%s%N returns the current time in nanoseconds since 1970-01-01 00:00:00 UTC.

error

object

error is the last observed error during snapshot creation, if any. Upon success after retry, this error field will be cleared.

readyToUse

boolean

readyToUse indicates if a snapshot is ready to be used to restore a volume. In dynamic snapshot creation case, this field will be filled in by the CSI snapshotter sidecar with the "ready_to_use" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "ready_to_use" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it, otherwise, this field will be set to "True". If not specified, it means the readiness of a snapshot is unknown.

restoreSize

integer

restoreSize represents the complete size of the snapshot in bytes. In dynamic snapshot creation case, this field will be filled in by the CSI snapshotter sidecar with the "size_bytes" value returned from CSI "CreateSnapshot" gRPC call. For a pre-existing snapshot, this field will be filled with the "size_bytes" value returned from the CSI "ListSnapshots" gRPC call if the driver supports it. When restoring a volume from this snapshot, the size of the volume MUST NOT be smaller than the restoreSize if it is specified, otherwise the restoration will fail. If not specified, it indicates that the size is unknown.

snapshotHandle

ParameterTypeDescription

allowWatchBookmarks

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

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

string

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

labelSelector

string

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

limit

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

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

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

timeoutSeconds

integer

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

watch

boolean

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

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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.
