The scheduler selects one node from the selected group (for example, node-3) and sets the status.allocation.nodeSelector field in the ResourceClaim to that node name. The dra.example.com/is-prepared binding condition indicates that the device gpu-1 must be prepared (the is-prepared condition has a status of True) before binding. If the gpu-1 device preparation fails (the preparing-failed condition has a status of True), the scheduler aborts binding. The scheduler waits up to 600 seconds (default) for the device to become ready. External controllers can use the node selector in the ResourceClaim to perform node-specific setup on the selected node.\n\nDevice binding conditions is a beta feature and is enabled by default, controlled by the DRADeviceBindingConditions feature gate in the kube-apiserver and kube-scheduler.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
