feat(recipes): gpuStack profile for the OKE family - #2355
Conversation
A profile value's distinguishing signal can be a post-deployment property (ADR-015 Deferred Decision 5): something the value's own deployment creates, such as a node label its installer DaemonSet applies. Such a signal cannot be declared today — profile-value constraints are evaluated at snapshot-based generation, where the property cannot yet exist, and the overlay-level readiness block cannot vary per value. Add ProfileValue.readinessConstraints: - validated at catalog load like constraints (non-empty name/value, per-list dedupe) and covered by the measurement-path gate, reported as spec.profile.values.<value>.readinessConstraints[i] - never evaluated at generation: applyEffectiveProfile routes the selected value's list into spec.validation.readiness.constraints, where the aicr validate readiness pre-flight evaluates it fail closed - names deduplicate per phase: the same measurement path may carry a generation-time pre-condition and a readiness-time post-deployment state (the DD5 shape reads NodeTopology.gpu-nodes.label in both phases) - ValidationConfig is cloned before mutation so a cached overlay's pointer is never aliased No embedded declaration uses the field yet, so resolved recipes, digests, and committed evidence are byte-identical. ADR-015 is amended with the DD5 resolution direction and a correction to the operator-selfdriver sketch: the component gate must be a nested key (installer.enabled), not top-level install, which is a component-presence gate and would deadlock resolution.

Address review: the sketch now declares the readinessConstraints it claims (positive marker on operator-selfdriver, symmetric absence on operator), the deferred gke-gpu-driver-version hardening is stated as deferred rather than landing (one constraint per measurement path per phase; needs a label conjunction grammar), a stale shared-namespace test comment now describes per-phase namespaces, and fail-closed is hyphenated as a compound modifier.

Convert OKE to the ADR-015 gpuStack configuration profile with three values, declared on oke-ol.yaml and inherited by every OL and Ubuntu leaf: - oci-default (default): the stock OKE cluster — Oracle's GPU node image supplies the driver and toolkit, and OKE's auto-installed device plugin is the nvidia.com/gpu advertiser (advertiser: external). The GPU Operator's plugin is disabled, correcting today's double-advertisement: the previous values-oke.yaml left the operator's plugin enabled while OKE's plugin also advertises on every default cluster. - operator-plugin: image-supplied driver, OKE's plugin disabled (the oci.oraclecloud.com/disable-gpu-device-plugin=true node label, or the NvidiaGpuPlugin add-on removed), the operator's plugin advertises. - operator-managed: bring-your-own driverless image — the operator installs driver, toolkit, and plugin, and the DRA driver root moves to /run/nvidia/driver in lockstep (issue #1087). The values are distinguished by deployed ClusterPolicy state via readinessConstraints (K8s.policy.driver.enabled and K8s.policy.devicePlugin.enabled — existing open-keyed readings, evaluated by the validate pre-flight). A generation-time gate on the disable-gpu-device-plugin node label is follow-up work: the gpu-nodes label constraint universe is GKE-specific today, and provisioning that removes the add-on leaves no on-node marker. Also absorbed into the profile or the family values: - nvsentinel.labeler.assumeDriverInstalled moves from the overlay into the per-value fragments, fixing the polarity under operator-managed (the operator's driver pod is the labeler's evidence; assuming a preinstalled driver would label GPU nodes before the driver is ready). - values-oke.yaml gains the universal OKE bare-metal device-plugin env (DEVICE_LIST_STRATEGY=cdi-annotations,cdi-cri,volume-mounts and MOFED_ENABLED=false — consequences of cri-o + CDI + host MOFED, which every OKE image carries). - nodewright-operator registry default bumps to v0.18.0: OKE's cri-o enforces short-name resolution and rejects the v0.17.1 chart's alpine/kubectl maintenance-hook image (NVIDIA/nodewright#481). operator.defaultRuntime is deliberately NOT set: production OKE cri-o clusters run the operator without it (runtime auto-detection), verified against live cluster state. Catalog and stock-render parity goldens regenerated (all OKE leaf digests move — the family-wide re-qualification event; nodewright bump moves the rest). BOM and recipe-health docs regenerated.

Validate the external OKE device plugin for operator-owned profiles.
Both readiness pairs only validate K8s.policy.*. A cluster with OKE's NvidiaGpuPlugin still enabled passes operator-plugin or operator-managed readiness when the GPU Operator ClusterPolicy has the expected values. The cluster then has two device-plugin managers. Oracle requires disabling the NVIDIA GPU Plugin as appropriate when using the GPU Operator to prevent this conflict. (docs.oracle.com)

Agreed, and this folds into the rework already conceded on the thread at line 135: the K8s.policy.* readings are the bundle's own output, so beyond missing the external-plugin conflict they don't qualify the cluster at all. The fix direction under discussion with the maintainers is a cluster-state signal — the oci.oraclecloud.com/disable-gpu-device-plugin node label (which is exactly the Oracle-documented switch for the conflict you cite) as a constraint, which needs the gpu-nodes evaluator's per-service label universe extended first. I'll rework both values' readiness (and soften the oke-gpu-setup.md pre-flight claim) once that direction is settled rather than patching the circular checks in place.

@atif1996, agreed. The K8s.policy.* readings validate the generated bundle state. They do not validate the existing OKE cluster state.
A gpu-nodes constraint on oci.oraclecloud.com/disable-gpu-device-plugin is the correct direction. It can verify the condition that prevents the external OKE device plugin from conflicting with the GPU Operator device plugin.
Keeping this thread open is appropriate until the OKE label universe support and the revised readiness constraints are available. The documentation should describe pre-flight behavior only after that cluster-state validation exists.

Learning: For OKE GPU stack profiles in `recipes/overlays/oke-ol.yaml`, `K8s.policy.*` readiness readings describe the generated bundle's GPU Operator `ClusterPolicy` state. They do not qualify the pre-existing OKE cluster state or prove that OKE's external `NvidiaGpuPlugin` is disabled. The intended validation direction is a cluster-state `gpu-nodes` constraint on the `oci.oraclecloud.com/disable-gpu-device-plugin` node label, after the `gpu-nodes` evaluator supports OKE's per-service label universe.

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:
- OKE provisioning sets
oci.oraclecloud.com/disable-gpu-device-plugin=trueon the GPU node pools — a real external signal the bundle does not write. - constraints: NodeTopology.gpu-nodes.label GPU-node universe is GKE-only #2359 generalizes the GPU-node universe so
NodeTopology.gpu-nodes.labelcan read it outside GKE. oci-defaultandoperator-pluginbecome declarable on ordinary generation-time constraints, with no need forreadinessConstraints.
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=truenode 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 offnvidia.com/gpu=true, which OKE's controller sets at bootstrap. - Caveat: DGXC provisioning currently removes the
NvidiaGpuPluginadd-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-poolsprovider projection (theproviderpools.gopattern, AKS parity): projectnodeSourceDetails.imageIdper GPU pool. Weaker than AKS'sgpuProfile.driverenum — 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 letGPU.hardware.driver-loadedsplit these two at generation without the self-falsification failure. That's anotherProfileValuefield 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?

Summary
Converts the OKE family to the ADR-015
gpuStackconfiguration 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) — distinguished at validate time by deployed ClusterPolicy state viareadinessConstraints.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.yamlalso documents the operator-managed driver flip as a manual four-path--setprocedure (the pre-profile AKS situation, #1757), andoke-ol.yamlhardcodesnvsentinel.labeler.assumeDriverInstalled: truechain-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 ofreadinessConstraints).Stacked on the
readinessConstraintsmechanism PR (#2347) — review that first; retargets tomainwhen it merges.Fixes: N/A
