resources.cSIDrivers

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: attribute set of (submodule)

Default: { }

Declared by:

resources.cSIDrivers.<name>.apiVersion

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.kind

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata

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

Type: null or (submodule)

Declared by:

resources.cSIDrivers.<name>.metadata.annotations

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

Type: null or (attribute set of (string))

Declared by:

resources.cSIDrivers.<name>.metadata.creationTimestamp

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

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.deletionGracePeriodSeconds

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

Type: null or signed integer

Declared by:

resources.cSIDrivers.<name>.metadata.deletionTimestamp

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

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.finalizers

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

Type: null or (list of (string))

Declared by:

resources.cSIDrivers.<name>.metadata.generateName

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

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

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.generation

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

Type: null or signed integer

Declared by:

resources.cSIDrivers.<name>.metadata.labels

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

Type: null or (attribute set of (string))

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields

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

Type: null or (list of (submodule))

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.apiVersion

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.fieldsType

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.fieldsV1

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

Type: null or (submodule)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.manager

Manager is an identifier of the workflow managing these fields.

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.operation

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.subresource

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.managedFields.*.time

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.name

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.namespace

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

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences

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

Type: null or (attribute set of (submodule) or list of (submodule))

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>._priority

This option has no description.

Type: null or signed integer

Default: null

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>.apiVersion

API version of the referent.

Type: string

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>.blockOwnerDeletion

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

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>.controller

If true, this reference points to the managing controller.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>.kind

Type: string

Declared by:

resources.cSIDrivers.<name>.metadata.ownerReferences.<name>.uid

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

Type: string

Declared by:

resources.cSIDrivers.<name>.metadata.resourceVersion

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

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

Type: null or (string)

Declared by:

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.metadata.uid

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

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

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.spec

spec represents the specification of the CSI Driver.

Type: submodule

Declared by:

resources.cSIDrivers.<name>.spec.attachRequired

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.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.spec.fsGroupPolicy

fsGroupPolicy 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 was immutable in Kubernetes < 1.29 and now is mutable.

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.

Type: null or (string)

Declared by:

resources.cSIDrivers.<name>.spec.podInfoOnMount

podInfoOnMount indicates this CSI volume driver requires additional pod information (like podName, podUID, etc.) during mount operations, if set to true. 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 VolumeContext 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 was immutable in Kubernetes < 1.29 and now is mutable.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.spec.requiresRepublish

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.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.spec.seLinuxMount

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”.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.spec.storageCapacity

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, if set to true.

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.

Type: null or boolean

Declared by:

resources.cSIDrivers.<name>.spec.tokenRequests

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.

Type: null or (list of (submodule))

Declared by:

resources.cSIDrivers.<name>.spec.tokenRequests.*.audience

audience is the intended audience of the token in “TokenRequestSpec”. It will default to the audiences of kube apiserver.

Type: string

Declared by:

resources.cSIDrivers.<name>.spec.tokenRequests.*.expirationSeconds

expirationSeconds is the duration of validity of the token in “TokenRequestSpec”. It has the same default value of “ExpirationSeconds” in “TokenRequestSpec”.

Type: null or signed integer

Declared by:

resources.cSIDrivers.<name>.spec.volumeLifecycleModes

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.

Type: null or (list of (string))
