# Dynamic Resource Allocation (DRA) GPU visibility

> Inspect Kubernetes DRA in Radar: ResourceClaim allocation lifecycle, DeviceClasses, ResourceSlices, and which Pods hold each device reservation.

[Dynamic Resource Allocation](https://kubernetes.io/docs/concepts/scheduling-eviction/dynamic-resource-allocation/) is Kubernetes' structured device-allocation API (GA in 1.34), replacing opaque extended-resource integers for GPUs and other accelerators. Workloads request devices through ResourceClaims, drivers publish inventory through ResourceSlices, and DeviceClasses define selectable device categories with CEL expressions.

These are built-in `resource.k8s.io` APIs, not CRDs - Radar discovers them automatically on any cluster that serves the group (1.32+ with the feature enabled, 1.34+ by default).

### What Radar Shows

**ResourceClaim Detail View:**

* Allocation lifecycle status: **Pending** (no device assigned), **Allocated** (devices assigned and reserved), or **Unreserved** - allocated but not held by any consumer, flagged with a warning since a long-lived unreserved claim leaks a device
* Device requests with their DeviceClass - handles every served API shape (`exactly` and `firstAvailable` subrequests in v1/v1beta2, flat `deviceClassName` in v1beta1)
* Allocation results: driver, pool, and device for each assigned request
* Reserved-for consumers with clickable Pod links
* Per-device health conditions when drivers report them

**Related Resources, both directions:**

* Pods show their ResourceClaims - direct references and template-generated claims (resolved through `status.resourceClaimStatuses`)
* Claims link back to their DeviceClasses and to the Pods holding the reservation

**DeviceClass Detail View:** CEL selector expressions and opaque driver configuration. A class with zero selectors matches all devices - Radar says so instead of showing an empty section.

**ResourceSlice Detail View:** the per-node device inventory a driver publishes - driver, pool, node link, and each device with its attributes (product name, driver version) and capacity (memory).

**Resource Browser:** claims list with allocation status, device class, allocated driver, and reservation columns - all filterable. ResourceSlices list driver, pool, node, and device count.

### Supported Kinds

| Kind                  | Group                           | Topology      | Detail View | AI Summary |
| --------------------- | ------------------------------- | ------------- | ----------- | ---------- |
| ResourceClaim         | `resource.k8s.io` (v1, v1beta2) | Relationships | Yes         | Yes        |
| ResourceClaimTemplate | `resource.k8s.io` (v1, v1beta2) | -             | Yes         | Yes        |
| DeviceClass           | `resource.k8s.io` (v1, v1beta2) | Relationships | Yes         | Yes        |
| ResourceSlice         | `resource.k8s.io` (v1, v1beta2) | -             | Yes         | Yes        |

<Note>
  GPU visibility doesn't require DRA: Radar also renders classic extended resources (`nvidia.com/gpu`, `amd.com/gpu`, `gpu.intel.com/*`) on node capacity, pod requests, and as a GPU column in the nodes and pods tables - it appears automatically when GPU-bearing rows load.
</Note>

### RBAC

Radar's Helm chart grants read access to the `resource.k8s.io` group by default (`rbac.crdGroups.dra: true`), so DRA objects show up with no extra setup. Set it to `false` if your org scopes Radar's RBAC more tightly and you don't run DRA.
