- Around line 57-58: Complete the GKE ownership migration across the stale
tables, retrofit procedure, and validation remediation: replace removed
driver-installer references with the bundle-managed gpuStack=bundle-installer
flow, and instruct users to delete any hand-applied
kube-system/nvidia-driver-installer DaemonSet before deploying the bundle.
Remove guidance that applies the standalone installer, while preserving the
bundle deployment and validation steps.
Apply the same fix in `@pkg/bundler/validations/checks.go` at line 457: The
validation remediation repeats the same conflicting manual-install instruction.
In
`@recipes/components/gcp-driver-installer/manifests/nvidia-driver-installer.yaml`:
- Around line 157-165: Update the GPU module detection logic around the
installer branch so a loaded NVIDIA module is not automatically treated as the
requested driver version. Compare the installed NVIDIA driver version with
driverVersion; continue only when they match, and when they differ, trigger the
supported node replacement or reboot workflow or fail explicitly instead of
exiting successfully.
In `@recipes/overlays/gke-cos.yaml`:
- Around line 117-121: Update the bundle-installer configuration under
componentRefs for gcp-driver-installer so partitionGpuImage uses a
multi-architecture image or an arm64-compatible override, while preserving the
installer enabled setting and ensuring this architecture-unconstrained profile
works on Grace and GB200 nodes.
In `@validators/deployment/expected_resources.go`:
- Around line 683-700: Add table-driven tests for gatedHealthCheckSuppressed
covering an installer that renders objects, an installer gated off, comment-only
output, render failure, and a non-gated component; assert suppression, reason,
and error outcomes, and use existing fixtures/helpers in
expected_resources_test.go.
- Around line 730-745: Propagate the validation context into
gatedHealthCheckSuppressed and emptyRenderHealthCheckSuppressed, then check
ctx.Ctx.Done() before each manifest read and render in the manifest loop. Return
the established cancellation result immediately when cancellation is observed,
while preserving existing manifest loading and rendering error handling.

Add the gcp-driver-installer component — Google's cos-gpu-installer DaemonSet as a values-gated, AICR-managed component — and replace the GKE gpuStack value driver-installer with bundle-installer, which owns it. The gpuStack family on GKE COS is now: - gke-default (default, unchanged): GKE's managed driver install and GKE's managed device plugin as the nvidia.com/gpu advertiser. - bundle-installer: opt-out pools (gke-no-default-nvidia-gpu-device-plugin=true, created with gpu-driver-version=disabled) — the GPU Operator's device plugin is the sole advertiser and the bundle's gcp-driver-installer component supplies the driver. The version is pinned in the recipe (gcp-driver-installer.driverVersion, default matching the GPU Operator chart's driver pin; must be COS-qualified) and upgrades roll with the bundle — nothing is applied out-of-band. The component sits unconditionally in the gke-cos chain, gated on the nested installer.enabled path (top-level install/enabled are component-presence gates and would deadlock profile resolution — ADR-015 sketch amended); under gke-default it renders a template-less no-op chart. The two values are distinguished at generation time by the opt-out pool label (negated vs positive), which resolves ADR-015 Deferred Decision 5 without any post-deployment signal. BREAKING: driver-installer (shipped v0.19.0) is removed; selecting it fails closed with the valid-values list. Migration for pools that used a hand-applied standalone nvidia-driver-installer DaemonSet: delete that DaemonSet (the bundle's DaemonSet shares its name in kube-system and Helm will not adopt the pre-existing object), regenerate with --profile gpuStack=bundle-installer, and deploy the bundle. Nodes with a loaded driver are untouched (installer fast path). Also: CheckNVSentinelDriverLabelDetectable accepts bundle-installer (the bundle-carried installer IS a driver pod the labeler detects); the deployment validator's static-assert suppression is generalized (gatedHealthCheckSuppressed) so a values-gated component whose render is empty skips its DaemonSet health check; cos-nvidia-installer:fixed gets a digest-pin exemption (COS-node-local image, never pulled or mirrored); parity goldens, BOM, and recipe-health docs regenerated. Fixes #1716 Related #2344 Signed-off-by: Atif Mahmood <atif1996@users.noreply.github.com>
Reduce the ADR-015 edits to the minimal decision-record changes: the Deferred Decision 5 resolution note, its short adoption-step counterpart, a one-line sketch-preamble redirect, and the gate-key correction where the sketch showed a pattern that deadlocks profile resolution. Cosmetic shipped-name annotations and example-command renames are dropped — an ADR records decisions, not running commentary. Signed-off-by: Atif Mahmood <atif1996@users.noreply.github.com>
- Rewrite the retrofit procedure for the bundle flow: step 0 deletes any hand-applied nvidia-driver-installer DaemonSet (Helm will not adopt the identically named object), and the ordering becomes driver-mode -> opt-out label -> bundle, with the scheduling gap and rollback semantics restated for the bundle-carried installer. - Make the installer's render gate nil-safe: a wholesale override that drops the installer key now renders nothing instead of failing the template (index of untyped nil). - Thread the deployment-phase context through gatedHealthCheckSuppressed and emptyRenderHealthCheckSuppressed (ctx-aware provider variants plus a per-manifest cancellation check), preserving the validator cancellation contract. - Add table-driven tests for the gated health-check dispatch: gated off, gated on, missing gate key, no manifests, unreadable manifest, non-gated component, canceled context. Signed-off-by: Atif Mahmood <atif1996@users.noreply.github.com>
The selection example still showed --profile gpuStack=driver-installer, which now fails closed — a reader copying it gets a resolution error. Use bundle-installer and annotate the historical rollout note so the replaced name is not read as current. Drawn value names in the sketch stay as originally proposed, per this ADR's existing convention (the preamble amendment maps drawn names to shipped names).

…tion The mode-comparison and NVSentinel tables in gke-gpu-setup.md still named the withdrawn driver-installer value and Google's standalone DaemonSet, and the COS remediation in checks.go told bundle-installer users to deploy a standalone DaemonSet the bundle now carries (and Helm cannot adopt).

Reviewed at 99ed026f. Requesting changes on the two P1s; the rest are text and can ride along.
Retracting one of my earlier findings. I previously flagged the GB200 qualification claim as contradicting the arm64 caveat. That was wrong — the claim qualifies the driver version against the COS curated list, while the caveat qualifies the partition image architecture. Different objects; both true at once. Not a defect here. #2338 must supply an arm64-compatible partitionGpuImage when it rebases.
P2 — the rename is incomplete. Profile-value references to the removed driver-installer remain in six places, none of them updated by this PR:
docs/user/validation.md:40-41— user-facing; presentsdriver-installeras a selectable value, so a reader runs--profile gpuStack=driver-installer, which no longer resolvesdocs/contributor/evidence-publishing.md:78-81recipes/components/gpu-operator/values-gke-cos.yaml:46tests/uat/gcp/cluster-config.yaml:142recipes/overlays/gke-cos.yaml:75pkg/bundler/validations/checks.go:1329
Only profile-name references should change — gcp-driver-installer and the nvidia-driver-installer DaemonSet name remain valid, as does the deliberately historical reference at docs/integrator/gke-gpu-setup.md:371.
A check that generalizes to any rename:
gh search code --repo NVIDIA/aicr "driver-installer" --json path -q '.[].path' | sort -u > /tmp/main-refs
gh pr view 2360 --repo NVIDIA/aicr --json files -q '.files[].path' | sort -u > /tmp/pr-files
comm -23 /tmp/main-refs /tmp/pr-filesChecked and clear, so you know these were looked at: the installer.enabled gate fails closed on a missing key or any non-true value; the health check guards against a vacuous pass (desiredNumberScheduled > 0); and an opt-out-label pool created with gpu-driver-version=default fails deployment validation rather than passing silently.
Not findings, just noting: the live H100 validation is still marked as planned in the PR body.
Out of scope, deliberately not raised: #2338's image override, the OKE / readinessConstraints design and #2359, and pool-mode qualification hardening beyond the documented supported configuration.
A correctly provisioned bundle-installer pool (gpu-driver-version=disabled, opt-out label) snapshots as gpuDriverState=absent with driver.enabled=false, so Rule 1 rejected the very bundle that carries the driver. Rule 1 and the resolution-time mismatch warning now consult the effective gcp-driver-installer installer gate (recipe values plus --set overrides, template-parity semantics), not the profile name.

🔍 Multi-persona review (+ adversarial meta-review)
Method: 4 independent persona lenses (Correctness · K8s/Operability · Domain/Recipe-Architecture · Test-coverage), each finding re-derived from the resolved code by a senior meta-reviewer. Pinned to head c0ede530.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Overlap note (not new work): @yuanchen8911 already holds a
CHANGES_REQUESTED. Their two code P1s (Rule-1 driverless gate; DaemonSet tolerations) are genuinely fixed — I independently reproduced and confirmed both. But their P2 rename-incompleteness is not resolved: the "purge residual references" commit (b8868ce30) only touchedgke-gpu-setup.md+checks.go, so 4 of the 6 files they enumerated never got a commit. Finding D1 below re-surfaces their highest-impact item — I'm not claiming it as novel.
Overall assessment
A carefully engineered breaking change — the gate logic, union totality, deploy ordering, and golden regeneration all hold up under adversarial scrutiny. No blocker survives. The two Major findings are about completeness of the fixes already claimed done, not new design defects:
- D1 — a user-guide page still instructs
--profile gpuStack=driver-installer, which this PR makes fail closed. - TC1 — the just-fixed tolerations P1 has zero rendered-content test coverage; the fallback can be deleted with every suite still green.
Recommendation: request changes in spirit (no blocker). Fix D1 (+ the cheap D2–D5 comment edits) and add one render-level test for the tolerate-all fallback (closes TC1 + TC2 + TC3 together). Everything else is optional hardening.
🔴 Blocker 0 | 🟠 Major 2 | 🟡 Minor 6 | 🔵 Nitpick 5
Findings on files this PR did not touch (can't be inline)
🟠 D1 — user guide still presents the removed driver-installer value as selectable
docs/user/validation.md#L41 — "…the default gke-default value requires … while driver-installer requires every GPU node to carry gke-no-default-nvidia-gpu-device-plugin=true". The only overlay value keys are now bundle-installer / gke-default, so following this runs a command that fails closed. Zero commits in the PR touch this file. This is @yuanchen8911's user-facing item, still open. Fix: driver-installer → bundle-installer.
🟡 D2 — recipes/overlays/gke-cos.yaml#L75 comment "Under driver-installer, Google's standalone nvidia-driver-installer DaemonSet supplies a driver pod…" — stale in a file the PR otherwise heavily edited.
🟡 D3 — recipes/components/gpu-operator/values-gke-cos.yaml#L46 comment maps the old value name "(driver-installer: true, gke-default: false)".
🟡 D4 — docs/contributor/evidence-publishing.md#L78 (and L81) references driver-installer evidence/cluster as a live value.
🔵 D5 — tests/uat/gcp/cluster-config.yaml#L142 comment "the label belongs only to the driver-installer value" (completes the rename sweep).
(The remaining driver-installer references — ADR-015 history prose, and the labelerObservesDriverPod hypothetical-external-value example at checks.go:1401 — are deliberately historical/illustrative and correct as-is.)
🔵 Other nitpicks (no action expected)
- CORR2
checks.go#L1401—labelerObservesDriverPodkeys off the profile name whileBundleSuppliesGKEDriverkeys off the effective gate; divergent only under an exotic--dataoverlay, both fail closed. By-design. - DOM1
015-...md#L245— ADR sketch draws 3 proposed value names, relying on the amendment note for the 2-value collapse. A one-line "(shipped set is two)" at the sketch head would remove the momentary ambiguity.
✅ Confirmed non-issues (examined and cleared)
- P1-A (Rule-1 driverless gate) —
BundleSuppliesGKEDriverkeys off the effective installer gate (values +--set), not the profile name;fmt.Sprint(installer["enabled"]) == "true"exactly mirrors the Helmeq (toString ...) "true"across bool/string/nil/non-map — no input renders the DaemonSet while Rule 1 rejects, or vice-versa. No import cycle (client/v1 → bundler/validationsbuilds clean). - P1-B (tolerations) — fallback logic is operationally correct; tolerate-all is safe because
nodeAffinitystill constrains placement. - No empty-release deadlock — the gated-off
gke-defaultchart installs instantly (zero resources), so thedependencyRefs: [gcp-driver-installer]edge on gpu-operator is satisfied immediately. Not the ClusterPolicy--waitbug class. - Union totality correct across overlay, ADR sketch, test (both values exercised), and chart gate; exactly two shipped values.
- Goldens clean — exactly the 6 GKE-COS recipes moved, zero non-GKE cross-contamination.
- Evidence-pointer staleness is non-gating —
evidence-pointercheckis structural, not digest-recomputing; the PR-body claim is accurate. - The snapshot-driven regression @yuanchen8911 asked for is present and correct (
driver-loaded=false, both suppressed + still-warning arms). - Health-check vacuous-pass / omitempty traps avoided; deployment ordering correct; the
chmodinstall-only path is fine.
Inline comments below carry the remaining findings anchored to the diff (TC1, OPS1, OPS2, CORR1, TC3, TC2).

🟠 Major — TC1 — the just-fixed tolerations P1 has no rendered-content test
Commit db82173 added this {{- else }} - operator: Exists tolerate-all fallback — the exact fix for @yuanchen8911's SDK-nil-config P1. But no test asserts the rendered toleration content: the "gated on renders objects" case only checks a boolean (renderedYAMLHasObjects == true). Deleting the entire else-branch leaves every relevant suite green (goldens gate the installer off under the default profile, so they never render it).
Blast radius: The fix that closed a P1 is unpinned — a future template edit can silently drop the fallback and SDK-generated bundles render the DaemonSet with no tolerations again → pods never schedule onto GKE-auto-tainted GPU pools → nodes stay driverless.
Fix: Add a render test that feeds an empty/nil acceleratedTolerations with installer.enabled=true through manifest.Render and asserts - operator: Exists appears under tolerations: (plus a case asserting the injected keyed toleration when acceleratedTolerations is non-empty). Closes TC2/TC3 alongside if you push string "true" and a resolution-error case through the same path.

🟡 Minor — OPS1 — health check can false-pass against a leftover unmanaged DaemonSet
The assert keys purely on name: nvidia-driver-installer / kube-system / status — the SAME name as the hand-applied installer this replaces (by design; Helm won't adopt it). During a migration where the old unmanaged DaemonSet is still Ready, the check certifies green against exactly the unmanaged, unpinned state the PR exists to eliminate.
Blast radius: GKE-COS bundle-installer migrations from the pre-existing hand-applied arrangement. Not a fresh-cluster concern.
Fix: Add app.kubernetes.io/managed-by: aicr to the asserted metadata.labels — the manifest already sets it (L67), so it only passes against the AICR-managed object. Free defense-in-depth.

🔵 Nitpick — OPS2 — OS-blind affinity + imagePullPolicy:Never can wedge on non-COS nodes
The nodeAffinity has no OS/COS predicate, while cos-nvidia-installer:fixed + imagePullPolicy: Never is a COS-node-local image. In a hand-mixed COS+Ubuntu cluster where both pool types carry the opt-out label and gpu-driver-version=disabled, the DaemonSet also schedules onto the Ubuntu GPU nodes → ErrImageNeverPull → those pods never go Ready.
Blast radius: Out-of-contract — the gke-cos overlay is scoped os:cos, so AICR only generates this bundle for COS. Requires a hand-mixed cluster. Noted because the affinity is the only thing steering placement and it doesn't encode the COS assumption the :fixed/Never image depends on.
Fix: Optional hardening: add a COS node-image predicate (e.g. cloud.google.com/gke-os-distribution In [cos]) so a non-COS GPU pool is excluded rather than left with wedged pods.

🔵 Nitpick — CORR1 — BundleSuppliesGKEDriver evaluated unconditionally before the Rule-1 guard
This call sits before the state==absent && (!driverEnabled || toolkitDisabled) guard, and its only consumer is that guard. So for every GKE-COS bundle through CheckDriverOwnershipCoherence — including a healthy gke-default bundle where GPUDriverState != absent — effectiveComponentValues(gcp-driver-installer, …) runs, and any resolution error hard-fails the whole bundle even though the driverless remediation would never fire.
Blast radius: Small in practice — the component always ships an embedded valuesFile that resolves locally, so this never false-positives on a healthy bundle. It is a strictly wider hard-fail surface than before. Documented intentional at L1162-1165.
Fix: Optional: evaluate BundleSuppliesGKEDriver lazily inside the if …GPUDriverStateAbsent && (…) branch so the supply check (and its hard-fail) only runs when Rule 1 would actually fire.

🟡 Minor — TC3 — BundleSuppliesGKEDriver fail-closed error path is untested
This return false, err is the branch the comments stress hardest (hard-fail rather than degrade to the misleading driverless remediation), yet it has 0% coverage — existing tests exercise CheckDriverOwnershipCoherence's own resolveErr, not this propagation, which needs gpu-operator to resolve but gcp-driver-installer to fail.
Blast radius: A regression that swallowed the error (returning false,nil) would go unnoticed and leave the driverless gate mis-armed depending on caller.
Fix: Add a case where gpu-operator resolves but gcp-driver-installer's valuesFile fails to resolve, asserting CheckDriverOwnershipCoherence returns a hard error (wantErrs: 1); plus a direct unit case for installer-as-non-map.

🟡 Minor — TC2 — template string-"true" gate parity asserted Go-side only
resultBundleInstaller("true") exercises only the Go gate (fmt.Sprint(...) == "true"). The independent Helm gate (eq (toString ...) "true") is never fed string "true" — only bool true is pushed through a render. If the template is later simplified to a bool compare, the Go check and template silently diverge and the 'template parity' comment becomes false.
Blast radius: A --set-json gcpdriverinstaller:installer.enabled='"true"' would make the Go gate report bundle-supplies-driver (Rule 1 stands down) while the template renders nothing → driverless deploy that passed validation.
Fix: Add one render-based test feeding installer.enabled as string "true" through manifest.Render and asserting the DaemonSet renders, co-located with the Go-side parity case so both gates are pinned together.

Summary
Adds the
gcp-driver-installercomponent — Google's cos-gpu-installer DaemonSet as a values-gated, AICR-managed component — and replaces the GKE gpuStack valuedriver-installerwithbundle-installer, which owns it: the bundle carries the driver installer, the version is pinned in the recipe, and upgrades roll with the bundle.Motivation / Context
The GKE COS chain can consume a driver but not produce one (#1716): on opt-out pools (
gke-no-default-nvidia-gpu-device-plugin=true,gpu-driver-version=disabled) the driver had to be supplied by hand-applying Google's standalone installer DaemonSet — an out-of-band prerequisite the recipe could neither version, order, nor validate. Production evidence for the bundle-carried arrangement is in #2344. Making the installer a recipe artifact closes the gap end-to-end:dependencyRefsorders it ahead of the GPU Operator, the driver version is a locked recipe value, and the whole mode is selected with one flag.Fixes: #1716

driver-installer(shipped in v0.19.0) is replaced: selecting--profile gpuStack=driver-installernow fails closed withvalid values: [bundle-installer gke-default].bundle-installeruses the same pool shape; the only migration step for clusters that hand-applied the standalonenvidia-driver-installerDaemonSet is to delete it before deploying (the bundle's DaemonSet shares its name inkube-system; Helm will not adopt the pre-existing object). Nodes with a loaded driver are untouched — the installer's fast path skips them.Implementation Notes
installer.enabled— top-levelinstall/enabledare component-presence gates and a false default would deadlock profile resolution (ADR-015 sketch amended). Undergke-defaultit renders a template-less no-op chart.gke-defaultasserts the opt-out label absent;bundle-installerasserts it present on pools createdgpu-driver-version=disabled. This resolves ADR-015 Deferred Decision 5 with no post-deployment signal.gcp-driver-installer.driverVersionis pinned in the recipe (580.173.02) and must be COS-qualified — the installer validates against the COS build's curated per-GPU-type list (verified for H100/A100/B200/GB200 on COS 125/129; COS 121 carries no qualifying R580 build). Version bumps take effect on replaced/rebooted nodes only.CheckNVSentinelDriverLabelDetectableacceptsbundle-installer(the bundle-carried installer IS a driver pod the labeler detects); the deployment validator's static-assert suppression is generalized (gatedHealthCheckSuppressed, same nodewright-customizations deployment health check fails when tuningEnabled=false suppresses the Skyhook CR #1844 mechanism as nodewright-customizations) so the empty-render selection skips the DaemonSet health check; GKE COS driver remediation text updated.cos-nvidia-installer:fixedis a COS-node-local image (imagePullPolicy: Never) — digest-pin exemption with rationale; it must never be mirrored. The partition-GPU image default is a literal so its digest lands in the BOM.gcp-driver-installer: [enabled, installer.enabled]joinsownedPathsfor every selection — all GKE recipe digests move (parity goldens regenerated); committed GKE evidence pointers become stale-advisory until re-published per value.Testing

Rollout notes: see Breaking change.
gke-defaultbehavior is unchanged apart from the expanded lock surface (--seton the installer gate now rejects). Downstream data repos that selectdriver-installerin CI must switch tobundle-installerwhen they bump.Checklist
