What

Brings the v1beta1 API group up to date and regenerates all derived artifacts, plus the minimal consumer adaptations needed to keep the tree building and testing green. Two commits:

1. [API] Update v1beta1 types, add AcceleratorQuota — the API surface itself:

  • New: AcceleratorQuota (cluster-scoped accelerator capacity budgets as a single-rooted Cohort/ClusterQueue tree materialized into Kueue objects, per-flavor budgets, explicit or proportional multi-cluster distribution, observed-capacity reporting); InferenceReplica ColumnarV2 instance-status encoding.
  • Updated: InferenceService spec (typed rollout groups with canary/blueGreen/rollingUpdate progressions and metric-gated analysis, traffic policy, per-Component autoscaler config with cross-Component scaling policy, multi-cluster placement, runtime pinning, model overlays, gang co-location) and status (per-Component revision tracking, autoscaler status, canary step state, coordination groups, placement + migration history); ServingRuntime types; BaseModel/FineTunedWeight additions.
  • Regenerated: CRDs (config + chart copies), deepcopy, client-go, openapi/swagger.

2. [Core] Adapt consumers to v1beta1 API update — align consumers with removed surfaces:

  • Autoscaling: per-Component scaleTarget/scaleMetric and spec-level kedaConfig are superseded by the typed per-Component autoscaler block; HPA/KEDA reconcilers fall back to annotation-driven and default paths; webhook-local legacy autoscaler validation removed (validation.ValidateAutoscalerConfig already covers the annotation surface).
  • Status: latestCreatedRevision is gone; revision derivation from Deployment/LWS metadata and the startup-failure gating tied to it are removed; pod lookups and the CLI status renderer use latestReadyRevision.
  • ServingRuntime webhook: the removed top-level workerPodSpec consistency check is dropped.
  • MaintainRatio.Tolerance is now *int32 (nil = unset).
  • Tests updated; suites asserting deleted validators dropped.

Testing

  • go build / go vet clean across pkg/, cmd/, internal/ (including test compilation).
  • Full unit suite green locally (the two exceptions are environment-specific: a local port collision in TestManagerSetup and a cache-dir env assumption in pkg/xet TestConfig_Validate; both untouched by this change).
  • make generate + make manifests re-run; no generated drift.

Summary by CodeRabbit

  • New Features

    • Added cluster-scoped AcceleratorQuota resources with quota, budget, distribution, capacity, and status tracking.
    • Added PerNode and Sharded model distribution modes, model cache details, and metadata status conditions.
    • Added compact ColumnarV2 instance-status reporting and configurable revision history limits.
    • Added serving-runtime scaling policies, cache-provider support, inheritance status, and conditions.
  • Changes

    • Enhanced rollout and canary status tracking with promotion and stable revision details.
    • Removed legacy KEDA and component-level scaling configuration fields.
    • Added status subresource support for serving-runtime resources.
    • Improved condition merging and readiness reporting.

Bring the v1beta1 API group up to date and regenerate all derived artifacts.

New:
- AcceleratorQuota: cluster-scoped accelerator capacity budgets as a single-rooted tree (Cohort / ClusterQueue nodes) materialized into Kueue objects, with per-flavor budgets, explicit or proportional multi-cluster distribution, and observed-capacity reporting.
- InferenceReplica ColumnarV2 instance-status encoding: a compact columnar representation of per-Instance status for large components.

Updated:
- InferenceService spec: typed rollout groups (canary / blueGreen / rollingUpdate progressions with metric-gated analysis steps), traffic policy (load-balancing algorithm, consistent hash, endpoint override), per-Component autoscaler configuration (HPA / KEDA / External / None) with cross-Component scaling policy, multi-cluster placement (Single / All / Split), serving-runtime pinning (autoSync / revision), model overlays, and gang co-location via topologyKey.
- InferenceService status: per-Component revision tracking and traffic targets, autoscaler status with a published scale target, canary step state with analysis results, rollout coordination groups, placement status, and migration history.
- Lifecycle types: instance update strategies (surge-then-drain, recreate, in-place), restart and readiness policies, migration records, per-revision retry blocks, and durable instance operations.
- Model types: sharded distribution with cache status, diffusion pipeline metadata, additional quantization formats; ServingRuntime inheritance status, model cache providers, and accelerator requirements; WorkloadCluster connection sources.
- AcceleratorClass status.conditions is now a map list keyed by type, so server-side apply merges conditions correctly.

Regenerated: deepcopy and defaulters, clientset / informers / listers, OpenAPI definitions and swagger, and the full and minimal CRD variants
(including the Helm chart copies).

📝 Walkthrough

Walkthrough

The change adds the AcceleratorQuota API and client support, introduces model distribution and ColumnarV2 replica status contracts, removes legacy autoscaler configuration, and updates inference-service reconciliation, validation, CRDs, generated code, and tests.

Changes

OME v1beta1 API and controller changes

Layer / File(s) Summary
AcceleratorQuota API and access layer
pkg/apis/ome/v1beta1/acceleratorquota_types.go, config/crd/*/ome.io_acceleratorquotas.yaml, charts/ome-crd/templates/ome.io_acceleratorquotas.yaml, pkg/client/.../acceleratorquota.go
Adds the cluster-scoped AcceleratorQuota API with quota budgets, capacity, distribution, projection, materialization, conditions, validation, and generated typed-client, informer, and lister support.
Model distribution and serving-runtime contracts
pkg/apis/ome/v1beta1/model.go, pkg/apis/ome/v1beta1/servingruntime_types.go, charts/ome-crd/templates/ome.io_{base,clusterbase}models.yaml, charts/ome-crd/templates/ome.io_finetunedweights.yaml
Adds PerNode and Sharded model distribution, cache status, model-cache providers, serving-runtime scaling policy, inheritance status, and related CRD fields.
ColumnarV2 replica status
pkg/apis/ome/v1beta1/inferencereplica_*.go, config/crd/full/ome.io_inferencereplicas.yaml, charts/ome-crd/templates/ome.io_inferencereplicas.yaml

InferenceService and rollout contracts
pkg/apis/ome/v1beta1/inference_service*.go, pkg/apis/ome/v1beta1/canary_status_types.go, pkg/apis/ome/v1beta1/rollout_types.go, config/crd/full/ome.io_inferenceservices.yaml
Removes legacy KEDA and scale fields, adds promotion and stable-revision status fields, changes rollout and tolerance contracts, and updates related API documentation.
Status reconciliation
pkg/controller/v1beta1/inferenceservice/status/*, pkg/controller/v1beta1/inferenceservice/components/base.go, pkg/cli/cmd/status/*
Stops populating LatestCreatedRevision, uses LatestReadyRevision for non-raw pod selection, simplifies model and container status propagation, and updates status output and tests.
Autoscaler and admission updates
pkg/controller/v1beta1/inferenceservice/reconcilers/{hpa,keda}/*, pkg/webhook/admission/{isvc,servingruntime}/*
Removes legacy autoscaler admission checks, uses default HPA and KEDA values, removes serving-runtime configuration validation, and updates or deletes obsolete tests.
Supporting API and generated updates
pkg/apis/ome/v1beta1/zz_generated.*, pkg/validation/*, config/crd/minimal/*, go.mod, hack/*
Updates generated deep-copy and defaulting code, pointer-based tolerance handling, condition list semantics, status subresources, dependency replacement, and API-rule exceptions.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 7ff95

This PR changes API, status, and quota behavior, but unresolved issues could cause status reconciliation to miss pods, preserve stale model failure state, or accept quota configurations that later fail or behave unexpectedly. Merge should wait for these bounded correctness and validation risks to be fixed or explicitly accepted by the owners.

319-321: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add DNS validation for namespace and cluster references.

Namespaces can contain values that Kubernetes cannot use as namespace names, so LocalQueue materialization can fail. Add item-level MaxLength=63 and DNS-1123 label Pattern markers.

AcceleratorClusterShare.Cluster references WorkloadCluster.metadata.name. Add the DNS-1123 subdomain Pattern alongside its existing MaxLength=253 marker.

Run make generate && make manifests after changing pkg/apis/.

- Around line 182-191: Ensure admission validation applies the operator-level
default distribution policy when both budget policy and spec.distribution.policy
are unset, so perCluster is required for resolved Explicit and rejected for
resolved Proportional. Update both validation sites in
config/crd/full/ome.io_acceleratorquotas.yaml (lines 182-191) and

- Around line 139-145: The pod selection in UpdateComponentStatus must match the
LWS labels and the per-revision Service-name value stored in
LatestReadyRevision; stop querying serving.knative.dev/revision for these pods
and select using leaderworkerset.sigs.k8s.io/template-revision-hash or add an
equivalent matching label. Add a regression test covering successful pod
selection and status reconciliation for LWS v0.5.1.

In `@pkg/controller/v1beta1/inferenceservice/status/status_util.go`:
- Line 139: Update the storage-initializer CrashLoopBackOff handling in the
status utility so that when hasTermination is false it explicitly sets the model
status to Pending, replacing any stale FailedToLoad state. Add a regression test
covering a storage initializer in CrashLoopBackOff with no LastTerminationState.

Enforce the configured default policy during admission. Both CRD copies allow perCluster when the budget and spec.distribution.policy are unset. The API contract says the operator-level quota configuration supplies the effective policy, so this input can violate either rule when that default is Explicit or Proportional. Validate the resolved policy in the webhook, or expose a fixed API default and regenerate both CRD copies.

sigs.k8s.io/lws v0.5.1 pod labels pod template serving.knative.dev/revision

💡 Result:

In the context of sigs.k8s.io/lws (LeaderWorkerSet) version 0.5.1, the pod labels and pod template serve distinct purposes from Knative Serving's serving.knative.dev/revision label. LeaderWorkerSet (LWS) and Knative Serving are separate Kubernetes projects. The serving.knative.dev/revision label is a specific identifier used by Knative Serving to track immutable snapshots of application code and configuration (Revisions) [1][2][3]. It is not a native component or requirement of the LeaderWorkerSet API. For LeaderWorkerSet v0.5.1, pod labels are managed by the LWS controller to orchestrate the leader-worker group. Key labels automatically injected by LWS into pod templates include [4]: - leaderworkerset.sigs.k8s.io/name: The name of the LeaderWorkerSet object [4]. - leaderworkerset.sigs.k8s.io/template-revision-hash: A hash used to track the controller revision that matches the LWS object [4]. - leaderworkerset.sigs.k8s.io/worker-index: The index or identity of the pod within the group [4]. While users can manually define labels in the leaderTemplate and workerTemplate fields of the LeaderWorkerSet spec [5][6], the serving.knative.dev/revision label has no functional integration with LWS. If you are attempting to use LWS pods within a Knative-managed environment, you would need to manually propagate or configure labels as required by your specific integration, as LWS does not natively support or respond to Knative revision labels [5][7].

Use a pod label that matches LatestReadyRevision.

UpdateComponentStatus selects non-RawDeployment pods with serving.knative.dev/revision=<LatestReadyRevision>. The LWS v0.5.1 controller does not provide this label; it uses leaderworkerset.sigs.k8s.io/template-revision-hash, while LatestReadyRevision now contains a per-revision Service name. The selector therefore returns no pods, and status reconciliation sets the model state to Pending. Add a matching pod label or select the LWS label, and add a regression test.

Set Pending when the storage initializer has no termination data.

When a prior reconciliation set FailedToLoad, the storage-initializer CrashLoopBackOff branch returns without replacing that state. A recreated initializer with no LastTerminationState then continues to report a failed load. Set Pending in this branch when hasTermination is false. Add a regression case for a storage-initializer CrashLoopBackOff with no termination data.

Proposed fix
 			case cs.State.Waiting != nil && cs.State.Waiting.Reason == constants.StateReasonCrashLoopBackOff:
 				message, exitCode, hasTermination := sr.safeGetTerminationMessage(cs)
 				if hasTermination {
 					sr.UpdateModelRevisionStates(status, v1beta1.FailedToLoad, totalCopies, &v1beta1.FailureInfo{
 						Reason:   v1beta1.ModelLoadFailed,
 						Message:  message,
 						ExitCode: exitCode,
 					})
+				} else {
+					sr.UpdateModelRevisionStates(status, v1beta1.Pending, totalCopies, nil)
 				}
 				return

Update the storage-initializer CrashLoopBackOff handling in the status utility
so that when hasTermination is false it explicitly sets the model status to
Pending, replacing any stale FailedToLoad state. Add a regression test covering
a storage initializer in CrashLoopBackOff with no LastTerminationState.

Follow-on to the v1beta1 type update: align the consumers that still
referenced removed API surfaces.

- Autoscaling: per-Component scaleTarget/scaleMetric fields and the
  spec-level kedaConfig are superseded by the typed per-Component
  autoscaler block. The HPA/KEDA reconcilers fall back to their
  annotation-driven and default paths; the webhook-local legacy
  autoscaler validation is removed (validation.ValidateAutoscalerConfig
  already covers the annotation surface).
- Status: latestCreatedRevision is gone from ComponentStatusSpec; the
  status reconciler no longer derives revisions from Deployment/LWS
  metadata and the container-startup-failure gating tied to it is
  removed. Pod lookups and the CLI status renderer use
  latestReadyRevision.
- ServingRuntime webhook: the top-level workerPodSpec field no longer
  exists, so the deployment-mode consistency check built on it is
  removed.
- Validation: MaintainRatio.Tolerance is now a pointer; nil means
  unset.
- Tests updated for the removed surfaces; suites asserting deleted
  validators are dropped.
