resource.v1beta1.resourceSlice

"ResourceSlice represents one or more resources in a pool of similar resources, managed by a common driver. A pool may span more than one ResourceSlice, and exactly how many ResourceSlices comprise a pool is determined by the driver.\n\nAt the moment, the only supported resources are devices with attributes and capacities. Each device in a given pool, regardless of how many ResourceSlices, must have a unique name. The ResourceSlice in which a device gets published may change over time. The unique identifier for a device is the tuple , , .\n\nWhenever a driver needs to update a pool, it increments the pool.Spec.Pool.Generation number and updates all ResourceSlices with that new number and new resource definitions. A consumer must only use ResourceSlices with the highest generation number and ignore all others.\n\nWhen allocating all resources in a pool matching certain criteria or when looking for the best solution among several different alternatives, a consumer should check the number of ResourceSlices in a pool (included in each ResourceSlice) to determine whether its view of a pool is complete and if not, should wait until the driver has completed updating the pool.\n\nFor resources that are not local to a node, the node name is not set. Instead, the driver may use a node selector to specify where the devices are available.\n\nThis is an alpha type and requires enabling the DynamicResourceAllocation feature gate."

fn metadata.withCreationTimestamp

withCreationTimestamp(creationTimestamp)

"Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers."

fn metadata.withDeletionGracePeriodSeconds

withDeletionGracePeriodSeconds(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."

fn metadata.withFinalizers

withFinalizers(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."

"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.\n\nIf this field is specified and the generated name exists, the server will return a 409.\n\nApplied only if Name is not specified.

"ResourcePool describes the pool that ResourceSlices belong to."

fn spec.pool.withGeneration

withGeneration(generation)

"Generation tracks the change in a pool over time. Whenever a driver changes something about one or more of the resources in a pool, it must change the generation in all ResourceSlices which are part of that pool. Consumers of ResourceSlices should only consider resources from the pool with the highest generation number. The generation may be reset by drivers, which should be fine for consumers, assuming that all ResourceSlices in a pool are updated to match or deleted.\n\nCombined with ResourceSliceCount, this mechanism enables consumers to detect pools which are comprised of multiple ResourceSlices and are in an incomplete state."

fn spec.pool.withName

withName(name)

"Name is used to identify the pool. For node-local devices, this is often the node name, but this is not required.\n\nIt must not be longer than 253 characters and must consist of one or more DNS sub-domains separated by slashes. This field is immutable."

fn spec.pool.withResourceSliceCount

withResourceSliceCount(resourceSliceCount)

"ResourceSliceCount is the total number of ResourceSlices in the pool at this generation number. Must be greater than zero.\n\nConsumers can use this to check whether they have seen all ResourceSlices belonging to the same pool."
