# io.k8s.api.resource.v1beta1.ResourceSlice

From **Kubernetes**.

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.

At 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 <driver name>, <pool name>, <device name>.

Whenever 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.

When 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.

For 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.

This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.

- Type: `object`

## Properties

### `apiVersion`

- Required: false
- Type: `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`

- Required: false
- Type: `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`

- Required: false
- Default: `{}`

Standard object metadata

### `spec`

- Required: true
- Default: `{}`

Contains the information published by the driver.

Changing the spec automatically increments the metadata.generation number.
