How to refresh evidenceRun on a cluster matching the recipe's aicr snapshot -o snapshot.yaml
# Profiled families (AKS/GKE gpuStack): hydrate the recipe with the
# pointer's recorded 'profile:' selection first — validating the raw
# overlay resolves only the declaration default, and 'aicr validate'
# has no --profile flag. AKS additionally needs the pool projection
# (GKE uses the plain snapshot above):
# az aks nodepool list -g <rg> --cluster-name <cluster> -o json > pools.json
# aicr snapshot --aks-gpu-pools pools.json -o snapshot.yaml
# aicr recipe -s snapshot.yaml --intent <intent> [--platform <platform>] \
# --profile <name>=<value> -o recipe.yaml
# State the target leaf's intent/platform explicitly (the snapshot
# fingerprint supplies service/accelerator/OS but intent and platform
# default to 'any') and pass -r recipe.yaml below instead of the raw
# overlay.

One structural concern on the readiness constraints — inline. Everything else in the OKE reasoning holds up, including the driver-loaded self-falsification point, which is worth capturing in the ADR as a general trap.

Approving. The gpuStack blocker is closed: the legacy-plugin tripwire detects Oracle's addon-manager-shipped device plugin, gates operator-managed only, and fails closed on the stock-cluster case — verified against the eleven resolve-against-snapshot cases in TestResolveRecipeFromSnapshot_OKEGpuStackQualification.
All other review items are addressed in code: the BOM re-render, the repo-wide --cluster-id sweep, the two-values doc correction, both --oke-addons flag-table rows, the --all usage note, and the projection/merge and warn-wrapper test coverage.
One non-blocking follow-up noted on the tripwire thread: an unlabeled nvidia-gpu-device-plugin DaemonSet collapses to none rather than unknown. Not reachable on any cluster we've observed — worth a separate issue, not a change here.

Worth flagging that this isn't a purely mechanical resolution: the BOM and both golden files need to be regenerated on top of the new gpu-operator/DRA pins rather than hand-merged. One request when you push: the re-render can pick up new images from the bumped charts, so I'd like to re-check |

Re-approving on ab68ae661 after the rebase. Content is unchanged from the approved 73cda78f apart from the two golden files absorbing #2544's new leaf, which I regenerated rather than hand-merged. BOM re-verified: only the disclosed nodewright v0.18.0 bump.
…jection Declares the two OKE cluster shapes as an ADR-015 gpuStack profile on the oke-ol family overlay: oci-managed (Oracle GPU image driver + the NvidiaGpuPlugin add-on advertising, advertiser: external) and operator-managed (bring-your-own driverless image with the add-on removed; the operator owns driver, toolkit, plugin, and the DRA root). MOFED is host-supplied in both values. The hybrid image-driver + operator-plugin shape is deliberately not declared — no consumer needs it, and the two-value model lets one control-plane signal qualify both ownership axes. Qualification (#2363, decided): the NvidiaGpuPlugin add-on's control-plane state, projected from an operator-supplied `oci ce cluster list-addons --all --output json` dump via a new --oke-addons flag on aicr snapshot and aicr validate — the AKS --aks-gpu-pools pattern (#1967) end to end: fail-loud file projection before any cluster work, controller-side merge in agent Job mode, validate re-captures with the same flag. installed → oci-managed, absent → operator-managed; any other lifecycle state projects a marker no constraint accepts, and a snapshot captured without the flag fails closed as reading-unavailable. Per-node label disablement (oci.oraclecloud.com/disable-gpu-device-plugin) is out of contract: it leaves the add-on installed. No ClusterPolicy readback, no driver-state gates, no readinessConstraints. Mechanism: pkg/collector/k8s/okeaddons.go (projection + normalization), K8s.oke-addons catalog row, snapshotter attach/merge (the AKS-named helpers generalize to attachProviderProjection/mergeProviderProjection), CLI flags with AICR_OKE_ADDONS_PATH, surface golden. gpu-operator values-oke.yaml drops the static driver/toolkit stanzas (profile-owned) and adds DEVICE_LIST_STRATEGY + MOFED_ENABLED devicePlugin env; the DRA values-oke.yaml drops nvidiaDriverRoot (profile-owned).

…-managed Older OKE clusters ship the NVIDIA device plugin through the legacy Kubernetes addon-manager (a kube-system/nvidia-gpu-device-plugin DaemonSet), which `oci ce cluster list-addons` cannot see - so a legacy cluster reads the NvidiaGpuPlugin add-on as absent, qualifies operator-managed, and the GPU Operator's plugin double-advertises nvidia.com/gpu alongside Oracle's (#1327). Review finding on this PR. Add an in-cluster tripwire, constrained by operator-managed only: - New K8s sub-collector (oke-legacy-plugin subtype): a read-only get of the DaemonSet, collapsed to none/active/unknown (detail preserved under the daemonset key). Unknown - including a clientless snapshot - fails constraints closed; "could not look" never reads as "absent". - The agent ClusterRole gains read-only apps/daemonsets. - operator-managed requires the reading none; oci-managed is deliberately not gated (the installed add-on reconciles the same DaemonSet name, so it would observe active on every healthy cluster). A legacy cluster therefore qualifies neither value: oci-managed fails via the add-on constraint (remediation: migrate to the add-on), operator-managed via the tripwire (remediation: per-pool disable label or add-on migration). Also folds in the two deferred review items: resolve-against-snapshot fail-closed tests covering the full qualification matrix, and the --all dependency note in the --oke-addons usage strings. Docs updated (oke-gpu-setup matrices + legacy-detection section + enhanced-cluster scope, measurement-api shape section, component-catalog paragraph).

Summary
Converts the OKE family to the ADR-015
gpuStackconfiguration profile with two values —oci-managed(Oracle GPU image driver + theNvidiaGpuPluginadd-on advertising) andoperator-managed(bring-your-own driverless image with the add-on removed; the operator owns driver, toolkit, plugin, and the DRA root) — qualified by a new OCI add-on projection:aicr snapshot|validate --oke-addons <oci ce cluster list-addons --all --output json dump>projects the add-on's control-plane state intoK8s.oke-addons.nvidia-gpu-plugin, and each value carries the matching durable constraint (installed/absent), evaluated at snapshot-based generation and re-evaluated by the validate pre-flight.Motivation / Context
OKE auto-installs NVIDIA's device plugin on every cluster, yet the OKE recipe leaves the GPU Operator's plugin enabled — a stock cluster double-advertises
nvidia.com/gpu(#1327).values-oke.yamlalso documented the operator-managed driver flip as a manual four-path--setprocedure, and hardcodednvsentinel.labeler.assumeDriverInstalled: truechain-wide.Design provenance: this implements the #2363 decision (settled with @yuanchen8911 on Slack). Two values, not three — the hybrid image-driver + operator-plugin shape has no consumer, and dropping it collapses both ownership axes onto one distinguishing signal (the GKE #2360 move). Qualification uses an external provisioning signal only: not ClusterPolicy readback (#2363 Option C, self-satisfying), not
GPU.hardware.driver-loaded— theNvidiaGpuPluginadd-on's actual control-plane state, mirroring the AKS--aks-gpu-poolsprojection (#1967) end to end (fail-loud file projection before any cluster work, controller-side merge in agent Job mode,validatere-captures with the same flag). Any non-ACTIVE lifecycle state projects a fail-closed marker; a snapshot captured without the flag fails closed as reading-unavailable. Per-node label disablement (oci.oraclecloud.com/disable-gpu-device-plugin) is out of contract — it leaves the add-on installed; clusters using it (e.g. NVCF today) migrate to add-on removal, the shape DGXC'sterraform-oci-okeclusteralready produces (NvidiaGpuPlugin = { remove = true }, verified on a live cluster). A supported-image consistency check is tracked as #2363 follow-up.Fixes: N/A

NvidiaGpuPluginadd-on's control-plane state — qualifies a selection. The earlier three-value iteration (a hybrid image-driver + operator-plugin shape) was withdrawn in the recipes: design grounded qualification for the OKE gpuStack profile #2363 decision: it has no consumer, and dropping it collapses the design onto the GKE feat(recipes)!: GKE bundle-installer replaces driver-installer #2360 single-signal move.K8s.oke-addons.nvidia-gpu-plugin(installedforoci-managed,absentforoperator-managed), evaluated at snapshot-based generation and re-evaluated by the validate pre-flight; nothing routes intovalidation.readiness, and there are noGPU.hardware.driver-loadedor ClusterPolicy-readback gates (both rejected in recipes: design grounded qualification for the OKE gpuStack profile #2363).kube-system/nvidia-gpu-device-pluginDaemonSet), whichlist-addonscannot see. A new in-cluster K8s sub-collector recordsK8s.oke-legacy-plugin.nvidia-gpu-device-plugin(none/active/unknown, uncollapsed detail under…daemonset; the agent ClusterRole gains read-onlyapps/daemonsets).operator-managedadditionally requiresnone, so a legacy cluster qualifies neither value —oci-managedfails via the add-on constraint (remediation: migrate to the managed add-on),operator-managedvia the tripwire (remediation: per-pooldisable-gpu-device-plugin=truelabel, or add-on migration).oci-managedis deliberately not gated on the tripwire: an installed add-on reconciles the same DaemonSet name.values-oke.yaml(not profile-owned; consumed only when the operator's plugin runs):DEVICE_LIST_STRATEGY=cdi-annotations,cdi-cri,volume-mountsandMOFED_ENABLED=false— consequences of cri-o + CDI + host MOFED on OKE bare metal (validated in production; without them NCCL breaks on SR-IOV clusters). devicePlugin.env is deliberately not profile-owned: Helm replaces lists, and downstream overlays must be able to restate it with additions.alpine/kubectlmaintenance-hook image (skyhook-operator-selector-migration PreSync hook fails to pull alpine/kubectl on runtimes with short-name resolution enforced nodewright#481); v0.18.0 fully qualifies it.operator.defaultRuntimedeliberately not set — production OKE cri-o clusters run the operator without it (auto-detection verified against live cluster state).nvsentinel:enabled=falsedisables will fail closed — intended, consistent with the sibling families, and flagged for downstream data repos.Behavior change (deliberate)
oci-managed(the default) rendersgpu-operator.devicePlugin.enabled: falsewhere today's recipe renders it enabled — the #1327 correction of the stock-cluster double-advertisement. Clusters where Oracle's plugin is genuinely absent (add-on removed, legacy DaemonSet absent or disabled) select--profile gpuStack=operator-managed, which preserves the operator-advertises rendering along with operator-owned driver/toolkit and the DRA root in lockstep. All OKE recipe digests move (ownedPaths expansion + nodewright bump) — catalog and stock-render parity goldens regenerated.Testing
