resource.v1beta2.deviceSubRequest

"DeviceSubRequest describes a request for device provided in the claim.spec.devices.requests[].firstAvailable array. Each is typically a request for a single resource like a device, but can also ask for several identical devices.\n\nDeviceSubRequest is similar to ExactDeviceRequest, but doesn't expose the AdminAccess field as that one is only supported when requesting a specific device."

Fields

fn withAllocationMode

withAllocationMode(allocationMode)

"AllocationMode and its related fields define how devices are allocated to satisfy this subrequest. Supported values are:\n\n- ExactCount: This request is for a specific number of devices.\n This is the default. The exact number is provided in the\n count field.\n\n- All: This subrequest is for all of the matching devices in a pool.\n Allocation will fail if some devices are already allocated,\n unless adminAccess is requested.\n\nIf AllocationMode is not specified, the default mode is ExactCount. If the mode is ExactCount and count is not specified, the default count is one. Any other subrequests must specify this field.\n\nMore modes may get added in the future. Clients must refuse to handle requests with unknown modes."

fn withCount

withCount(count)

"Count is used only when the count mode is \"ExactCount\". Must be greater than zero. If AllocationMode is ExactCount and this field is not specified, the default is one."

fn withDeviceClassName

withDeviceClassName(deviceClassName)

"DeviceClassName references a specific DeviceClass, which can define additional configuration and selectors to be inherited by this subrequest.\n\nA class is required. Which classes are available depends on the cluster.\n\nAdministrators may use this to restrict which devices may get requested by only installing classes with selectors for permitted devices. If users are free to request anything without restrictions, then administrators can create an empty DeviceClass for users to reference."

fn withName

withName(name)

"Name can be used to reference this subrequest in the list of constraints or the list of configurations for the claim. References must use the format

/.\n\nMust be a DNS label."

fn withSelectors

withSelectors(selectors)

"Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this subrequest. All selectors must be satisfied for a device to be considered."

fn withSelectorsMixin

withSelectorsMixin(selectors)

"Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this subrequest. All selectors must be satisfied for a device to be considered."

fn withTolerations

withTolerations(tolerations)

"If specified, the request's tolerations.\n\nTolerations for NoSchedule are required to allocate a device which has a taint with that effect. The same applies to NoExecute.\n\nIn addition, should any of the allocated devices get tainted with NoExecute after allocation and that effect is not tolerated, then all pods consuming the ResourceClaim get deleted to evict them. The scheduler will not let new pods reserve the claim while it has these tainted devices. Once all pods are evicted, the claim will get deallocated.\n\nThe maximum number of tolerations is 16.\n\nThis is an alpha field and requires enabling the DRADeviceTaints feature gate."

fn withTolerationsMixin

withTolerationsMixin(tolerations)

"If specified, the request's tolerations.\n\nTolerations for NoSchedule are required to allocate a device which has a taint with that effect. The same applies to NoExecute.\n\nIn addition, should any of the allocated devices get tainted with NoExecute after allocation and that effect is not tolerated, then all pods consuming the ResourceClaim get deleted to evict them.

obj capacity

"CapacityRequirements defines the capacity requirements for a specific device request."

fn capacity.withRequests

withRequests(requests)

"Requests represent individual device resource requests for distinct resources, all of which must be provided by the device.\n\nThis value is used as an additional filtering condition against the available capacity on the device. This is semantically equivalent to a CEL selector with device.capacity[<domain>].<name>.compareTo(quantity(<request quantity>)) >= 0. For example, device.capacity['test-driver.cdi.k8s.io'].counters.compareTo(quantity('2')) >= 0.\n\nWhen a requestPolicy is defined, the requested amount is adjusted upward to the nearest valid value based on the policy. If the requested amount cannot be adjusted to a valid value—because it exceeds what the requestPolicy allows— the device is considered ineligible for allocation.\n\nFor any capacity that is not explicitly requested: - If no requestPolicy is set, the default consumed capacity is equal to the full device capacity\n (i.e., the whole device is claimed).\n- If a requestPolicy is set, the default consumed capacity is determined according to that policy.\n\nIf the device allows multiple allocation, the aggregated amount across all requests must not exceed the capacity value. The consumed capacity, which may be adjusted based on the requestPolicy if defined, is recorded in the resource claim’s status.devices[*].consumedCapacity field."
