Summary

Bumps the GPU stack to the current upstream releases — GPU Operator v26.3.3v26.7.0, its pinned NVIDIA driver 580.173.02595.91.07, and the NVIDIA DRA driver (base and OCP) 0.4.10.5.0 — and fixes a ComputeDomain CRD conflict that v26.7.0 introduces.

Allocation behaviour is unchanged: ClusterPolicy with the device plugin as the whole-GPU advertiser, and the standalone DRA driver serving ComputeDomain/IMEX. GPUCluster is not adopted.

Motivation / Context

The catalog is two GPU Operator minors behind. v26.7.0 (2026-08-21) and DRA driver 0.5.0 (2026-08-19) are current, and 0.5.0 lists "Support deployment with the NVIDIA GPU Operator v26.7.0" as a feature — they are the pairing upstream validates.

Fixes: N/A
Related: #2383 (pinned-version audit), #2403 (GPUCluster consolidation — explicitly not adopted here), #1253 (closed; the DRA eviction wiring from #2401 is unaffected), #2312 (Flux CRD ownership)

Implementation Notes

ComputeDomain CRD conflict — the one behaviour fix here

v26.7.0's chart gained three CRDs its predecessor did not ship, two of them in the resource.nvidia.com group:

v26.3.3 crds/: nvidia.com_clusterpolicies.yaml, nvidia.com_nvidiadrivers.yaml
v26.7.0 crds/: + nvidia.com_gpuclusters.yaml
               + resource.nvidia.com_computedomains.yaml
               + resource.nvidia.com_computedomaincliques.yaml

resource.nvidia.com_computedomains.yaml is also shipped by the standalone DRA driver chart, and gpu-operator's copy is a stale snapshot:

gpu-operator v26.7.0 dra-driver-nvidia-gpu 0.5.0
spec.required [channel, numNodes] [channel]
spec.numNodes no default, no minimum default: 0, minimum: 0

Helm installs crds/ only when the CRD is absent and never upgrades it, and gpu-operator is ordered before nvidia-dra-driver-gpu. So on a fresh cluster the operator's stricter copy wins, and recipes/components/slinky-slurm/manifests/compute-domain.yaml — which omitted numNodes — would be rejected with spec.numNodes: Required value. Structural defaulting cannot fill it because that copy has no default: 0.

Fix: pin numNodes: 0 on the CR, plus a regression guard (TestComputeDomainManifestsSetNumNodes) asserting every ComputeDomain manifest in the catalog sets the key, so a future CR cannot reintroduce the hazard. Valid under both copies, and 0 is the correct value rather than a placeholder — with IMEXDaemonsWithDNSNames=true (the DRA driver default) each IMEX daemon starts immediately instead of waiting for a quorum. It matches buildComputeDomain() in validators/performance/nccl_all_reduce_bw_constraint.go, which already sets numNodes: 0 for the same reason.

Reachable in a supported configuration: gb200-eks-ubuntu-training-slurm is a shipped overlay with UAT coverage, and the CR is a slinky-slurm pre-manifest applied unconditionally. Fresh installs only — an existing cluster keeps the DRA-installed CRD, which is why an upgrade-path test would not surface it.

Neither component declares ownsCRDs: true, so the #2312 Flux CRD-replace path does not correct this on its own.

The driver moves with the chart

Holding an older driver against a newer chart is a combination upstream does not test, so both move together.

To be precise about what changed: the previous pin 580.173.02 was deliberately ahead of the v26.3.3 chart default (580.126.20) to clear a GB200+EFA floor — it was not simply the chart's recommendation. 595.91.07 is the v26.7.0 chart default and is far above that floor, so pin and recommendation coincide again. They are not the same thing, and the values comment now records both the history and the rule for a future chart default that regresses below it.

The pin itself stays. Taking the chart default as a value is not the same as leaving the driver unpinned — the pin keeps a future chart bump an explicit driver decision instead of a silent fleet-wide driver change, and keeps BOM and attestation inputs deterministic.

gcp-driver-installer is deliberately left at 580.173.02

That component requests a driver from the node's COS release, and cos-gpu-installer validates the request against the COS build's curated per-GPU-type list — an unqualified pin crash-loops the DaemonSet. 595.91.07 has not been confirmed against the COS catalog. GKE COS sets driver.enabled: false, so the GPU Operator pin is inert there; the two driver paths are independent.

GPUCluster is not adopted

v26.7.0 introduces it, but it ships experimental and deployCR: false, and it forces whole-GPU DRA cluster-wide, which cannot express today's default. Tracked in #2403. This bump is allocation-neutral by construction.

useOpenKernelModules replaced with kernelModuleType

driver.useOpenKernelModules: true was a no-op. The chart deprecated it and the identical note appears in both v26.3.3 and v26.7.0 values.yaml, so the key had already stopped having any effect before this pin moved — our clusters have been running the chart default kernelModuleType: auto regardless of what that line said.

Replaced with an explicit kernelModuleType: auto. That records today's effective behaviour rather than changing it: it is the chart default on both versions, and it is the fallback the OCP ClusterPolicy template already renders (components/gpu-operator-ocp/manifests/clusterpolicy.yaml). Per the ClusterPolicy CRD, auto selects the recommended module type from the host's GPU devices and driver branch, which yields open modules on Blackwell/Grace where they are required.

Setting "open" instead would pin the intent the dead key expressed — but that IS a behaviour change on any hardware where auto currently selects proprietary, so it needs its own validation rather than riding a version bump.

Render goldens move for 46 of 48 leaves as a result. The two that do not — ocp-inference-nim and ocp-training — consume gpu-operator-ocp and its separate values file. Catalog goldens are unchanged, because values content affects rendering but not recipe resolution.

Operand versions carried by the chart bump

Operand Before After
driver 580.173.02 595.91.07
k8s-device-plugin v0.19.3 v0.20.0
container-toolkit v1.19.1 v1.20.0
dcgm 4.5.2-1-ubuntu22.04 4.6.0-1-ubuntu24.04
dcgm-exporter 4.5.3-4.8.2 4.6.0-4.8.3
k8s-driver-manager v0.11.0 v0.12.0
k8s-mig-manager v0.14.2 v0.15.0
k8s-cc-manager v0.4.0 v0.4.3
vgpu-device-manager v0.4.2 v0.5.0
kubevirt-gpu-device-plugin v1.5.0 v1.6.0
nvidia-sandbox-device-plugin v0.0.3 v0.0.5
gdrdrv v2.5.2 v2.6
nvidia-fs 2.27.3 2.29.4

DCGM's base image moves from Ubuntu 22.04 to 24.04.

DRA driver 0.5.0's new capabilities (HostManagedIMEXDaemon, FabricManagerPartitioning, ConsumableShares, DRAListTypeAttributes) are all alpha and default-off, so the bump changes no behaviour by itself. It carries ComputeDomain fixes relevant to our usage: CD domain ID validated before IMEX config generation, and no longer failing on incomplete fabric registration on non-MNNVL nodes. Chart kubeVersion is unchanged on both charts (>= 1.16.0-0, >= 1.32.0-0).

Stale version references refreshed

The bump made a number of version-specific claims stale. Each behavioural claim in Go comments was re-verified against v26.7.0 / DRA 0.5.0 before its cited version was updated — all seven still hold:

  • transformForDriverInstallDir early-returns on "" exactly like the default (object_controls.go:881-883)
  • clusterpolicy.yaml:17 still accesses .Values.hostPaths.rootFS unconditionally
  • the ClusterPolicy CRD still types driverInstallDir as string
  • _helpers.tpl:79 still reads .Values.driver.manager.repository
  • operator.runtimeClass still defaults to nvidia
  • driverInstallDir still defaults to /run/nvidia/driver
  • the DRA chart still defaults nvidiaDriverRoot to /

The GKE-Ubuntu driver-management note was de-versioned rather than re-pinned, because it is a support-matrix claim rather than a chart fact and was not verified against v26.7.0.

Also refreshed: the GPU CI chart pin in .settings.yaml (so the GPU lanes exercise the chart the catalog ships rather than one two minors behind), a chainsaw comment mirroring the driver-validation rationale, the ccManager note (ccManager.enabled: true re-verified in v26.7.0), the AKS toolkit-hardening note (the v1.20.0 changelog shows no change to the volume-mount device-request path, so the security rationale stands), and copyable samples in docs/, demos/ and examples/.

One of those was more than cosmetic: examples/recipes/eks-gb200-ubuntu-training-with-validation.yaml carried a value: "== v26.3.3" exact-match constraint that would have failed validation against a v26.7.0 deployment.

Golden digests regenerated

TestCatalogParityGolden and TestStockRenderParityGolden fail on any change to a leaf's resolved or rendered bytes and ask for justification when intended. Both were regenerated with AICR_UPDATE_GOLDEN=1.

  • Version bump: all 48 golden entries moved, none unchanged — gpu-operator and nvidia-dra-driver-gpu come from base.yaml, so every leaf inherits them. A partial change would have signalled leakage into a subset of recipes. The diffs contained only leaf: sha256 lines.
  • numNodes + comment edits: 5 leaves moved — 2 slurm leaves from the CR change, and 4 AKS leaves because nvidia-toolkit-hardening-aks.yaml is a rendered manifest whose comments land in bundle output verbatim (h100-aks-ubuntu-training-slurm is in both sets).

Testing

make bom-docs
AICR_UPDATE_GOLDEN=1 go test ./pkg/recipe/... -run TestCatalogParityGolden
AICR_UPDATE_GOLDEN=1 go test ./pkg/bundler/... -run TestStockRenderParityGolden
make qualify

make qualify is re-running against the current head after the guard fix and the kernelModuleType consumer sweep; the result will be recorded here. It passed on the earlier version-bump tree. The only SDK surface change api-diff reports is compatible: (*Config).DRAEvictionNodeLabel: added, from the separately-merged #2401.

Cluster validation — outstanding, this PR stays in draft until it is done:

  • GB200 + EFA on EKS — highest signal. The old pin was tied to a GB200+EFA floor, and driver.rdma.enabled: false exists because v26.3.3's stricter driver-validation broke EFA. Covers NCCL/OFI and MNNVL/IMEX against the 595-series driver.
  • gb200-eks-ubuntu-training-slurm on a fresh cluster — specifically exercises the ComputeDomain CRD fix. An upgrade-path test will not surface it.
  • H100 or B200 on EKS — same global pin, operator-managed driver path.
  • One provider-installed platform (GKE COS or AKS)driver.enabled: false, so this exercises operand-versus-host-driver compatibility rather than the driver bump. AKS additionally runs toolkit.enabled: false, so the node image's toolkit meets the newer operands.
  • Confirm all three CRDs new to the v26.7.0 chart apply cleanly on Flux upgrades (fix(bundler): let CRD-owning components replace their CRDs on Flux upgrade #2312) — gpuclusters.nvidia.com, and the two that overlap the DRA driver chart: computedomains.resource.nvidia.com and computedomaincliques.resource.nvidia.com. The overlapping pair is the consequential one; neither component declares ownsCRDs: true, so the Flux CRD-replace path does not reconcile the divergent copies.

Recipe evidence goes stale — expected, not a merge condition

The Verify recipe evidence (warning-only) check reports 10 pointers across 8 protected recipes as stale: gb200-eks-ubuntu-training, gb300-eks-ubuntu-inference-dynamo, gb300-eks-ubuntu-training-kubeflow, h100-aks-ubuntu-inference-dynamo, h100-aks-ubuntu-training-kubeflow, h100-aks-ubuntu-training, h100-gke-cos-training, rtx-pro-6000-eks-ubuntu-inference-dynamo.

That is the expected consequence of changing pinned versions: the recipe digest moves, so previously-signed evidence no longer matches it. It is the warning gate doing its job, not a defect in this change.

It does not gate merge. That check is warning-only by design (its own workflow: "Workflow 2 of 2 for the warning-only recipe-evidence gate"), and it is not in main's required status checks. The separate blocking evidence gate is evidence-pointer-contract.yaml, which enforces the on-disk pointer contract for committed pointers — this PR adds none, so it has nothing to trip.

Three additional entries report registry-forbidden (HTTP 401). That is a fork-registry access limitation (the fork's aicr-evidence package is not public), unrelated to this diff and equally true of any fork PR.

Regenerating evidence against the new pins is hardware-gated downstream work for each recipe's owner, tracked separately from this bump.

Risk Assessment

  • Low — Isolated change, well-tested, easy to revert
  • Medium — Touches multiple components or has broader impact
  • High — Breaking change, affects critical paths, or complex rollout

A driver version change rolls every GPU node in the operator-managed families. The diff is small and easily reverted, but its runtime blast radius is the whole GPU fleet, and the EFA path has prior history with driver-validation strictness.

Rollout notes: Operator-managed families (EKS and the base default) take a driver upgrade, which drains and reloads GPU nodes. Provider-installed families (AKS, GKE COS, OKE) keep their host driver; only operands move. v26.7.0 adds in-place driver pod restarts when the driver configuration digest is unchanged, so cosmetic chart-label changes no longer drain nodes — but this bump does change the driver, so nodes will roll.

Checklist

  • Tests pass locally (make test with -race) — re-running
  • Linter passes (make lint) — golangci-lint ./pkg/recipe/... reports 0 issues
  • I did not skip/disable tests to make CI green
  • I added/updated tests for new functionality — TestComputeDomainManifestsSetNumNodes; goldens regenerated with justification above
  • I updated docs if user-facing behavior changed — BOM regenerated; docs, demos and examples aligned
  • 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

The PR remains mergeable with owner follow-up: the ComputeDomain regression test should validate each YAML document independently, and AKS toolkit version documentation remains inconsistent. These issues weaken regression protection and documentation accuracy but do not show a current deployment failure.

gpu-operator v26.7.0 ships a stale copy of the ComputeDomain CRD in crds/ that
marks numNodes required with no default. Helm installs crds/ only when absent
and gpu-operator is ordered before nvidia-dra-driver-gpu, so on a fresh cluster
the operator's copy wins and the slinky-slurm ComputeDomain CR is rejected with
"spec.numNodes: Required value". Pin numNodes: 0 explicitly, which is valid
under both CRD copies and is the correct value under IMEXDaemonsWithDNSNames.

Also refresh version references the bump made stale: the GPU CI chart pin, a
chainsaw comment mirroring the driver-validation rationale, the ccManager and
toolkit-hardening comments, and a hand-written sample in the BOM page.

Verified each version-specific behavioral claim in Go comments against
v26.7.0 / DRA 0.5.0 before updating the cited version: transformForDriverInstallDir
still early-returns on "", clusterpolicy.yaml still accesses .Values.hostPaths.rootFS
unconditionally, the ClusterPolicy CRD still types driverInstallDir as a string,
_helpers.tpl still reads .Values.driver.manager.repository, operator.runtimeClass
still defaults to nvidia, driverInstallDir still defaults to /run/nvidia/driver,
and the DRA chart still defaults nvidiaDriverRoot to "/". The GKE Ubuntu
driver-management note is de-versioned rather than re-pinned, since it is a
support-matrix claim rather than a chart fact.

Docs, demos and example recipes carried the old versions in copyable samples and
in one exact-match constraint (== v26.3.3), which would have failed validation
against a v26.7.0 deployment.

…azard

gpu-operator v26.7.0 and the standalone DRA driver both ship a
computedomains.resource.nvidia.com CRD, and the copies differ: the operator's
marks numNodes required with no default. Helm installs crds/ only when absent
and gpu-operator is ordered first, so a fresh cluster gets the stricter copy and
rejects any ComputeDomain CR omitting numNodes. An upgraded cluster masks this
because DRA 0.4.1 already installed the permissive copy, so no upgrade-path e2e
would catch a regression here.

The guard ignores comment lines: these manifests legitimately discuss
"spec.numNodes: Required value" in prose, and a naive substring scan matched
that instead of the key — passing even with the key deleted. Verified by
deleting numNodes and confirming the test fails, then restoring it. Also fails
closed when the walk matches no manifests, so it cannot go silently inert.

misspell rejects "analogue"; the US spelling is required by the lint gate.

Three stale references the earlier refresh missed:
- demos/dynamic.md grepped for 'version: 580' to prove the dynamic value had
  been removed from baked values. With the pin at 595.91.07 that grep returns 0
  whether or not the substitution worked, so the check no longer proved
  anything. The chainsaw suite it mirrors uses a 999.99.99 sentinel and is
  unaffected.
- the driver-root lockstep comment still named DRA chart 25.12.0 while its own
  error text had been updated to 0.5.0.
- the AKS setup guide still named toolkit v1.19.1 while the manifest it
  documents now names v1.20.0.

The guard matched numNodes anywhere in the file. A multi-document manifest where
one ComputeDomain sets the key and a second omits it would pass while still
failing admission, as would an unrelated resource carrying a numNodes key. No
such manifest exists today; scoping per document means adding one cannot
silently bypass the guard. Two independent reviews raised this.

Dropping the whole-file helper also removes its fake generic signature — it took
a key parameter, ignored it in the regex, and panicked on anything but
"numNodes".

Controls verified both ways: deleting numNodes fails, and appending a second
ComputeDomain document without it fails naming document 2. Restoring passes.

Also updates two comments in checks_test.go that mirror comments in checks.go
which this branch already moved to v26.7.0; the claims were verified against the
v26.7.0 chart and still hold.

…leType

The chart deprecated useOpenKernelModules and made it a no-op; the identical
NOTE appears in v26.3.3 and v26.7.0 values.yaml, so the key had already stopped
having any effect before this pin moved. Our clusters have been running the
chart default kernelModuleType: auto regardless of what that line said.

Pinning "auto" records today's effective behaviour rather than changing it: it
is the chart default on both versions and the fallback the OCP ClusterPolicy
template already renders. Setting "open" would pin the intent the dead key
expressed, but that is a real behaviour change wherever auto currently selects
proprietary, so it needs its own validation rather than riding a version bump.

Render goldens move for 46 of 48 leaves. The two that do not, ocp-inference-nim
and ocp-training, consume gpu-operator-ocp and its separate values file. Catalog
goldens are unchanged because values content affects rendering but not recipe
resolution.

…ype consumers

The guard matched numNodes anywhere in the ComputeDomain document, so moving the
key to metadata.numNodes still passed while Kubernetes would reject the absent
spec.numNodes. Matching a key without its parent is not a weaker check, it is
the wrong check. The scanner now requires numNodes as a DIRECT CHILD of spec,
walking indentation because the manifests are Helm templates no YAML parser
accepts.

Adds table cases covering every shape that has fooled a previous version of this
scanner or must keep working: present, absent, under metadata, comment-only,
nested under spec.channel, and templated. Plus a multi-document case asserting
only the offending document is reported.

Replacing useOpenKernelModules also broke four consumers that were not updated
with it — a chainsaw bundle assertion (which fails CLI E2E), the OpenAPI
response example, the query demo output, and the OCP values comment. Changing a
values key requires sweeping its consumers, the same discipline applied to the
version strings in this branch.
