Summary

Converts the OKE family to the ADR-015 gpuStack configuration profile with three values — oci-default (stock OKE: Oracle-image driver + OKE's auto device plugin), operator-plugin (image driver, GPU Operator's plugin), operator-managed (bring-your-own driverless image; operator installs driver+toolkit+plugin). Qualification implements only what is groundable today (#2363): the driver axisGPU.hardware.driver-loaded=true as a durable generation constraint on the image-driver values, and its post-deployment form as a readiness-scoped deployment-outcome check on operator-managed (the first consumer of #2347's readinessConstraints, used per its contract). The advertiser axis is deliberately unqualified pending #2363.

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, which the #1327 policy forbids. values-oke.yaml also documents the operator-managed driver flip as a manual four-path --set procedure (the pre-profile AKS situation, #1757), and oke-ol.yaml hardcodes nvsentinel.labeler.assumeDriverInstalled: true chain-wide — wrong wherever the operator installs the driver. The profile fixes all three, following the AKS declaration shape and the GKE family's conversion (#2044), and is the third consumer of the profile machinery (second of readinessConstraints).

#2347 has merged; this branch is rebased directly onto main (no longer stacked).

Fixes: N/A
Related: #2363, #2347, #1327, #2175

Type of Change

  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)

Component(s) Affected

  • Recipe engine / data (pkg/recipe)
  • Docs/examples (docs/, examples/)

Implementation Notes

  • Why three values: pools provisioned with the OKE plugin disabled (node label oci.oraclecloud.com/disable-gpu-device-plugin=true or the NvidiaGpuPlugin add-on removed) but Oracle-image drivers are a real, distinct shape — image driver + operator plugin. Two values cannot express it.
  • Constraint design (reworked per review + recipes: design grounded qualification for the OKE gpuStack profile #2363): the original K8s.policy.* readiness constraints were rejected as self-satisfying — they read back the bundle's own rendered .spec (recipes: design grounded qualification for the OKE gpuStack profile #2363 Option C). Replaced with the groundable subset: oci-default/operator-plugin require GPU.hardware.driver-loaded=true at generation (durable — the image driver persists, so the validate pre-flight's re-evaluation holds; a driverless BYO cluster fails closed with remediation steering to operator-managed). operator-managed carries no generation driver gate (the self-falsifying-precondition trap) — instead the post-deployment form is a readiness-scoped deployment-outcome check per the merged ADR-015 contract: it verifies the operator's install executed, and explicitly does not qualify the value. The advertiser axis (oci-default vs operator-plugin) has no evaluable external signal yet — the disable-gpu-device-plugin label is outside the gpu-nodes evaluator's GKE-only universe and DGXC removes the add-on labellessly — so it remains an explicit --profile choice until recipes: design grounded qualification for the OKE gpuStack profile #2363 selects a signal.
  • Universal OKE truths added to values-oke.yaml (not profile-owned; consumed only when the operator's plugin runs): DEVICE_LIST_STRATEGY=cdi-annotations,cdi-cri,volume-mounts and MOFED_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.
  • nodewright-operator registry default → v0.18.0: OKE cri-o enforces short-name resolution and rejects v0.17.1's alpine/kubectl maintenance-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.defaultRuntime deliberately not set — production OKE cri-o clusters run the operator without it (auto-detection verified against live cluster state).
  • nvsentinel presence becomes profile-owned on OKE (as on AKS/GKE): nvsentinel:enabled=false disables will fail closed — intended, consistent with the sibling families, and flagged for downstream data repos.

Behavior change (deliberate)

oci-default (the default) renders gpu-operator.devicePlugin.enabled: false where today's recipe renders it enabled — the #1327 correction of the stock-cluster double-advertisement. operator-plugin preserves the previous rendering for pools where OKE's plugin is disabled. All OKE recipe digests move (ownedPaths expansion + nodewright bump) — catalog and stock-render parity goldens regenerated.

Testing

make qualify           # green
go test ./... subset   # 31 packages ok; lint 0 issues
  • New pkg/recipe/profile_oke_test.go: 3-value table — ownership tuple, advertiser, declaration-wide ownedPaths, readiness routing (and no leakage into spec.constraints).
  • nvsentinel_gpustack_test.go: the TestOKENVSentinelValueIsNotProfileOwned asymmetry test inverted per its own instructions; three per-value polarity rows added.
  • Render matrix: all three values recipe+bundle cleanly (OL and Ubuntu leaves); profile lock verified (--set gpuoperator:devicePlugin.enabled=true on an oci-default recipe rejects with the owned-path diagnostic).
  • Docs: new docs/integrator/oke-gpu-setup.md; component-catalog, cli-reference, README index, BOM, recipe-health regenerated.

Risk Assessment

  • Medium — Touches multiple components or has broader impact

Rollout notes: Stock-OKE users get the corrected single-advertiser default on regeneration; anyone relying on the operator's plugin on stock clusters selects --profile gpuStack=operator-plugin. Downstream --data repos that disable nvsentinel on OKE must stop (presence now profile-owned).

Checklist

  • Tests pass locally (make test with -race)
  • Linter passes (make lint)
  • I did not skip/disable tests to make CI green
  • I added/updated tests for new functionality
  • I updated docs if user-facing behavior changed
  • Changes follow existing patterns in the codebase
  • Commits are cryptographically signed (git commit -S)

How to refresh evidence

Run on a cluster matching the recipe's criteria:

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.
aicr validate \
  -r recipes/overlays/<slug>.yaml \
  -s snapshot.yaml \
  --emit-attestation ./out \
  --push ghcr.io/<your-fork>/aicr-evidence
# Copy to the per-source path printed in the emit 'copyTo' hint:
#   recipes/evidence/<slug>/<source>/<bundle-digest>.yaml

📝 Walkthrough

Walkthrough

The OKE recipe now uses API version aicr.run/v1alpha3 and supports oci-default, operator-plugin, and operator-managed gpuStack profiles. Profiles control GPU Operator components, DRA driver roots, NVSentinel behavior, and validation constraints. Component overrides and tests enforce profile ownership. Documentation covers setup and restrictions. OKE parity golden digests were regenerated.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 93cc3

The PR changes OKE GPU profile behavior and related guidance; outdated readiness documentation could mislead future maintenance, and a malformed validation table could confuse integrators. These are bounded documentation issues with no supplied evidence of a merge-blocking runtime problem, so merge is reasonable with owner follow-up.

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.

The three values all declare readinessConstraints on K8s.policy.driver.enabled and K8s.policy.devicePlugin.enabled (here, and again at 177 and 220). I don't think those readings distinguish the three pool shapes, which undercuts what the profile is claiming to qualify.

The selected bundle is what renders those two fields. So after deployment each value satisfies its own readiness constraints by construction, regardless of whether OKE's device-plugin add-on was actually removed or whether the node image shipped a driver. Pick the wrong value for a cluster, deploy it, and pre-flight still passes — the constraint is reading back the recipe's own output, not the external state the value is meant to describe.

The collector compounds this: pkg/collector/k8s/policy.go flattens discovered ClusterPolicy specs without retaining object identity or provenance, so the readings can't even attest which object they came from.

That makes these useful rendered-policy drift checks — they catch a hand-edited ClusterPolicy or a different recipe deployed over this one — but not profile qualification. ADR-015 requires a constraint distinguishing each value from its siblings, and self-satisfying constraints don't meet it.

Suggested direction: declare only what can be qualified. Drop the values no external signal separates rather than declaring them with a caveat. Documenting that we can't distinguish them doesn't make declaring them permissible under ADR-015 — it just records the gap. If that means the OKE profile waits, that seems right: it's the same call made on the GKE side, where driver-installer was dropped precisely because the recipe could neither own nor verify it. Two adjacent PRs resolving the same problem in opposite directions would be hard to defend later.

That leaves a concrete path to a qualified two-value profile rather than a dead end:

  1. OKE provisioning sets oci.oraclecloud.com/disable-gpu-device-plugin=true on the GPU node pools — a real external signal the bundle does not write.
  2. constraints: NodeTopology.gpu-nodes.label GPU-node universe is GKE-only #2359 generalizes the GPU-node universe so NodeTopology.gpu-nodes.label can read it outside GKE.
  3. oci-default and operator-plugin become declarable on ordinary generation-time constraints, with no need for readinessConstraints.

To be precise about what that does not solve: the label separates oci-default from the other two, but not operator-plugin from operator-managed — both disable OKE's plugin and differ only in driver ownership. operator-managed still needs an independent, durable driver-ownership signal the bundle does not create, which is the harder half of the problem.

Note step 3 cuts at #2347: if the OKE profile lands via the label route, the mechanism's only proposed consumer goes away. Not an argument against the mechanism itself, but it does argue against merging it ahead of the thing that justifies it.

The alternative I'd accept is finding some other external-state marker that OKE's add-on removal or the node image leaves behind and the bundle never writes. If one exists, that's strictly better than deferring — I just don't see a candidate in the analysis so far.

Either way the wording should change too: as written, a passing pre-flight reads as confirmation the cluster matches the selected value, and it isn't that. That's worth fixing alongside whichever direction you pick, not instead of one.

Flagging rather than blocking — the direction is yours to choose.

Concretely, on why the readings can't qualify: select operator-managed on a pool whose node image already ships a driver, deploy it, and the readiness constraints pass — K8s.policy.driver.enabled=true is true because this bundle set it, not because the cluster needed it. The same holds in reverse for operator-plugin on a pool where OKE's add-on was never removed. Both are wrong-mode selections that pre-flight reports as qualified.

And to be concrete about what deferring means: ship oci-default and operator-plugin, hold operator-managed until there is a driver-ownership signal. The label prerequisite is the NKX-9804 gap you referenced earlier — worth linking it here so the dependency is visible.

Conceded in full — the K8s.policy.* readings are the bundle's own output, so each value satisfies its own readiness constraints by construction. They're drift checks (hand-edited ClusterPolicy, different recipe deployed over this one), not qualification, and the collector's lack of object provenance makes that worse. Your framing is now codified in the mechanism PR's ADR amendment (9ed09df on #2347): self-rendered readings do not qualify; qualification requires cluster state independent of the bundle's own output — along with the driver-loaded self-falsification trap as a general rule.

For this PR (still draft, so rework is free), the honest options for real qualification, per value pair:

oci-default vs the other two — the external truth is whether OKE's auto device plugin is disabled on the GPU pools:

  • The durable, snapshot-visible marker is the oci.oraclecloud.com/disable-gpu-device-plugin=true node label (Oracle's quickstart and NVCF both set it at pool creation). Declaring it needs one Go change — pkg/constraints/gpu_nodes.go's GPU-node universe is GKE-hardcoded (cloud.google.com/gke-accelerator); OKE's universe would key off nvidia.com/gpu=true, which OKE's controller sets at bootstrap.
  • Caveat: DGXC provisioning currently removes the NvidiaGpuPlugin add-on via the cluster API instead of setting the label (tracked internally as an NVCF-alignment gap), so adopting this constraint has a provisioning-side prerequisite before DGXC clusters can satisfy it.

operator-plugin vs operator-managed — the external truth is whether the node image ships a driver; no on-node marker survives deployment (the operator installing the driver erases the "no driver" pre-condition — the trap). Two candidate shapes:

  • An --oke-node-pools provider projection (the providerpools.go pattern, AKS parity): project nodeSourceDetails.imageId per GPU pool. Weaker than AKS's gpuProfile.driver enum — OCIDs aren't self-describing, so image-driver-ness is an inference; arguably fails the fail-closed spirit.
  • A generation-only constraint mechanism (the mirror image of readinessConstraints: evaluated at snapshot-based generation, excluded from the validate re-evaluation) — which would let GPU.hardware.driver-loaded split these two at generation without the self-falsification failure. That's another ProfileValue field and another ADR amendment, so it needs the same scrutiny this mechanism is getting.

My lean: land the universe extension + label constraint for the first split (with the provisioning prerequisite stated), keep the K8s.policy.* entries but demoted to documented drift checks rather than the declaration's distinguishers, and take the second split as a follow-up decision between the projection and generation-only constraints — the profile can't honestly declare operator-plugin/operator-managed as separately qualified until one of those exists, which may argue for shipping OKE with two values first (oci-default + a single operator-owned value) and splitting later. Which direction do you want before I rework the draft?

Closing the loop: the rework landed in 93cc3a4 — Option C constraints deleted; driver axis grounded via GPU.hardware.driver-loaded (generation constraint on the image-driver values, deployment-outcome readiness check on operator-managed per the merged #2347 contract); advertiser axis deferred to #2363.

Note

GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer.

Declares the three OKE cluster shapes as an ADR-015 gpuStack profile on
the new oke-ol family overlay: oci-default (Oracle GPU image driver,
OKE's auto-installed device plugin advertising), operator-plugin (image
driver, operator's plugin advertising), operator-managed
(bring-your-own driverless image; the operator owns driver, toolkit,
plugin, and the DRA root). MOFED is host-supplied in every value.

Qualification implements only what is groundable today (issue #2363):
the driver axis. oci-default and operator-plugin require
GPU.hardware.driver-loaded=true at generation — durable, since the
image driver persists across the validate pre-flight's re-evaluation —
and operator-managed carries the post-deployment form as a
readiness-scoped deployment-outcome check per the ADR-015 contract
(verifies the install executed; does not qualify the value). The
advertiser axis is deliberately unqualified pending #2363: the
disable-gpu-device-plugin node label is outside the gpu-nodes
evaluator's GKE-only universe, and DGXC removes the add-on without
setting the label.

gpu-operator values-oke.yaml drops the static driver/toolkit stanzas
(profile-owned now) and adds DEVICE_LIST_STRATEGY + MOFED_ENABLED
devicePlugin env; the DRA values-oke.yaml drops nvidiaDriverRoot
(profile-owned).

Rebuilt on merged main — old HEAD fe764f38, new HEAD 93cc3a4c (draft-phase rewrite; single commit, no longer stacked on #2347, which merged).

The constraint design is reworked per this review and #2363: all K8s.policy.* readiness constraints are gone (Option C, self-satisfying readbacks — conceded). What replaces them is the groundable subset only: GPU.hardware.driver-loaded=true as a durable generation constraint on oci-default/operator-plugin (image driver persists → validate re-evaluation holds; driverless BYO clusters fail closed toward operator-managed), and its post-deployment form on operator-managed as a readiness-scoped deployment-outcome check per the merged ADR-015 contract — the first real consumer of #2347's mechanism, verifying execution without claiming qualification. The advertiser axis stays deliberately unqualified pending #2363 (label vs add-on projection, plus the gpu-nodes evaluator's GKE-only universe), stated plainly in the overlay, the setup doc's new qualification table, and the description. Verified by resolution: the outcome check routes to validation.readiness.constraints, the generation constraint to spec.constraints.

| Axis | Signal | Status |
|---|---|---|
| Driver (image vs operator) | `GPU.hardware.driver-loaded` on the sampled GPU node | **Qualified.** `oci-default` and `operator-plugin` require it `true` at generation — durable, since the image driver persists and the `aicr validate` pre-flight re-evaluates the same constraint. A driverless (bring-your-own image) cluster fails both with remediation steering to `operator-managed`. `operator-managed` carries the post-deployment form as a readiness-scoped **deployment-outcome check**: it verifies the operator's driver install executed; it does not prove the value was the right choice. |
| Advertiser (OKE plugin vs operator plugin) | undecided | **Deferred.** Candidate signals — the `oci.oraclecloud.com/disable-gpu-device-plugin` node label vs a cluster add-on projection — are unresolved, and the node-label constraint evaluator's universe is GKE-only today. `oci-default` vs `operator-plugin` is currently an explicit `--profile` choice; verify the plugin state on your pools yourself (`kubectl get ds -n kube-system | grep nvidia-gpu-device-plugin`). |

Escape the pipe in the validation command.

The | grep ... sequence is parsed as a fourth table cell. The validation table has three columns, so the row can render incorrectly. Escape the pipe as \| or move the command outside the table.

Proposed fix
-... `kubectl get ds -n kube-system | grep nvidia-gpu-device-plugin`.
+... `kubectl get ds -n kube-system \| grep nvidia-gpu-device-plugin`.

Correct the test description.
