apiVersion: resource.k8s.io/v1
import "k8s.io/api/resource/v1"
DeviceClass is a vendor- or admin-provided resource that contains device configuration and selectors. It can be referenced in the device requests of a claim to apply these presets. Cluster scoped.
| Field | Description |
|---|---|
apiVersionstring |
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 |
kindstring |
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 |
metadataObjectMeta |
Standard object metadata |
spec *DeviceClassSpec |
Spec defines what can be allocated and how to configure it. This is mutable. Consumers have to be prepared for classes changing at any time, either because they get updated or replaced. Claim allocations are done once based on whatever was set in classes at the time of allocation. Changing the spec automatically increments the metadata.generation number. |
DeviceClassSpec is used in a [DeviceClass] to define what can be allocated and how to configure it.
| Field | Description |
|---|---|
configDeviceClassConfiguration array |
Config defines configuration parameters that apply to each device that is claimed via this class. Some classses may potentially be satisfied by multiple drivers, so each instance of a vendor configuration applies to exactly one driver. They are passed to the driver, but are not considered while allocating the claim. |
extendedResourceNamestring |
ExtendedResourceName is the extended resource name for the devices of this class. The devices of this class can be used to satisfy a pod's extended resource requests. It has the same format as the name of a pod's extended resource. It should be unique among all the device classes in a cluster. If two device classes have the same name, then the class created later is picked to satisfy a pod's extended resource requests. If two classes are created at the same time, then the name of the class lexicographically sorted first is picked. This is a beta field. |
selectorsDeviceSelector array |
Each selector must be satisfied by a device which is claimed via this class. |
DeviceClassList is a collection of classes.
| Field | Description |
|---|---|
apiVersionstring |
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources |
items *DeviceClass array |
Items is the list of resource classes. |
kindstring |
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 |

CELDeviceSelector contains a CEL expression for selecting a device.
| Field | Description |
|---|---|
expression *string |
Expression is a CEL expression which evaluates a single device. It must evaluate to true when the device under consideration satisfies the desired criteria, and false when it does not. Any other result is an error and causes allocation of devices to abort. The expression's input is an object named "device", which carries the following properties: - driver (string): the name of the driver which defines this device. - attributes (map[string]object): the device's attributes, grouped by prefix (e.g. device.attributes["dra.example.com"] evaluates to an object with all of the attributes which were prefixed by "dra.example.com". - capacity (map[string]object): the device's capacities, grouped by prefix. - allowMultipleAllocations (bool): the allowMultipleAllocations property of the device (v1.34+ with the DRAConsumableCapacity feature enabled). Example: Consider a device with driver="dra.example.com", which exposes two attributes named "model" and "ext.example.com/family" and which exposes one capacity named "modules". This input to this expression would have the following fields: device.driver device.attributes["dra.example.com"].model device.attributes["ext.example.com"].family device.capacity["dra.example.com"].modules The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers. The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity. If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort. A robust expression should check for the existence of attributes before referencing them. For ease of use, the cel.bind() function is enabled, and can be used to simplify expressions that access multiple attributes with the same domain. For example: cel.bind(dra, device.attributes["dra.example.com"], dra.someBool && dra.anotherBool) When the DRAListTypeAttributes feature gate is enabled, the includes() helper is available and it can work for both scalar and list-type attributes. It was introduced to support smooth migration from scalar attributes to list-type attributes while keeping CEL expressions simple. For example: device.attributes["dra.example.com"].models.includes("some-model") The length of the expression must be smaller or equal to 10 Ki. The cost of evaluating it is also limited based on the estimated number of logical steps. |
DeviceClassConfiguration is used in DeviceClass.
| Field | Description |
|---|---|
opaqueOpaqueDeviceConfiguration |
Opaque provides driver-specific configuration parameters. |
DeviceSelector must have exactly one field set.
| Field | Description |
|---|---|
celCELDeviceSelector |
CEL contains a CEL expression for selecting a device. |
OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.
| Field | Description |
|---|---|
driver *string |
Driver is used to determine which kubelet plugin needs to be passed these configuration parameters. An admission policy provided by the driver developer could use this to decide whether it needs to validate them. Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver. It should use only lower case characters. |
parameters * |
Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions. The length of the raw data must be smaller or equal to 10 Ki. |

integer | The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately. |
ignoreStoreReadErrorWithClusterBreakingPotential |
boolean | if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it |
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. |

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 |

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it |
labelSelector |
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. |

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 |
sendInitialEvents |
boolean | `sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise. |
shardSelector |
string | shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate. |

Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate. |

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. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget). |
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 |
sendInitialEvents |
boolean | `sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise. |
shardSelector |
string | shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space.
