Since kube-scheduler only records individual Pods in that list, only 256 Pods can share a ResourceClaim. By allowing PodGroups to be recorded in status.reservedFor, many more than 256 Pods can share a ResourceClaim. Pods can only share a ResourceClaim when its exact name is known. For complex workloads that replicate _groups_ of Pods, ResourceClaims shared by the Pods in each group need to be created and deleted explicitly when the set of groups scales up and down. By generating ResourceClaims for each PodGroup, a single ResourceClaimTemplate can form the basis for ResourceClaims that are both replicated automatically and shareable among the Pods in a PodGroup.\n\nThe PodGroup API defines a spec.resourceClaims field with the same structure and similar meaning as the spec.resourceClaims field in the Pod API\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: scheduling.k8s.io/v1alpha2\nkind: PodGroup\nmetadata:\n  name: training-group\n  namespace: some-ns\nspec:\n  ...\n  resourceClaims:\n  - name: pg-claim\n    resourceClaimName: my-pg-claim\n  - name: pg-claim-template\n    resourceClaimTemplateName: my-pg-template\n```\n\nLike claims made by Pods, claims for PodGroups defining a resourceClaimName refer to a ResourceClaim by name. Claims defining a resourceClaimTemplateName refer to a ResourceClaimTemplate which replicates into one ResourceClaim for the entire PodGroup that can be shared amongst its Pods. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
