feat(recipes): register nvcre Helm component

[rorajani]

Summary

Registers the public Cluster Readiness Engine Helm chart (nvcre, chart v0.2.0-rc.2) in the component registry so operators can install CRE from a recipe. No overlay attaches nvcre, so TrainJob NCCL remains the shipped EKS H100 default.

Motivation / Context

CRE is public at https://github.com/NVIDIA/cluster-readiness-engine. The validator CRE checks live in a companion PR; this change only makes the chart installable. Attaching nvcre to h100-eks-training would force CRE onto every consumer because AICR has no optional-component switch.

Fixes: N/A
Related: #2519

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Refactoring (no functional changes)
• Build/CI/tooling

Component(s) Affected

• CLI (cmd/aicr, pkg/cli)
• API server (cmd/aicrd, pkg/server)
• Recipe engine / data (pkg/recipe)
• Bundlers (pkg/bundler, pkg/component/*)
• Collectors / snapshotter (pkg/collector, pkg/snapshotter)
• Validator (pkg/validator)
• Core libraries (pkg/errors, pkg/k8s)
• Docs/examples (docs/, examples/)
• Other: recipes/registry.yaml, recipes/components/nvcre, recipes/checks/nvcre

Implementation Notes

• Chart: oci://ghcr.io/nvidia / cluster-readiness-engine v0.2.0-rc.2, namespace nvcre, ownsCRDs: true.
• Health check is registered for make check-health COMPONENT=nvcre.
• TestNVCRERegisteredWithoutOverlay asserts the registry entry exists and that no overlay componentRefs name nvcre.
• Component catalog documents the install as opt-in; BOM lists the manager image from the pinned chart.
• Pinned to v0.2.0-rc.2 rather than v0.1.0: v0.2.0 ships the SLSA provenance and Sigstore attestations v0.1.0 lacked. The pin moves to the final v0.2.0 tag in a follow-up once it is cut. Re-audited the CRDs per ownscrds_audit_test.go (bumping defaultVersion re-arms that gate) — same seven nvcre.nvidia.com CRDs, no cross-component name collisions, no webhook conversion, so ownsCRDs stays true.

Testing

GOFLAGS=-mod=mod go test -count=1 ./pkg/recipe/ -run 'TestNVCRERegisteredWithoutOverlay'
GOFLAGS=-mod=mod go test -count=1 ./tools/bom/ -run 'TestCommittedBOMVersionsMatchRegistry'
golangci-lint run -c .golangci.yaml ./pkg/recipe/...

Registry/BOM tests passed. Full make qualify not run in this pass.

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

Rollout notes: Registry-only. Recipes that do not list nvcre are unchanged. Do not add a componentRef to a shipped overlay until TrainJob correlation and an optional-component mechanism exist.

Checklist

• Tests pass locally (make test with -race) — targeted packages above
• Linter passes (make lint) — golangci-lint on ./pkg/recipe/...
• 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) — GPG signing info

📝 Walkthrough

Walkthrough

Added the opt-in nvcre component for the NVIDIA Cluster Readiness Engine. The registry configures its chart, namespace, CRD ownership, health check, aliases, and scheduling tolerations. The health check validates the manager Deployment, required CRDs, LogProfile, and Pod states. Registry tests verify opt-in installation behavior. Catalogs document the component and its container image.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 71b90

This adds an opt-in NVCRE component with chart registration, health checks, and documentation without changing existing recipes. No current merge-blocking risk remains.

How this PR related to #2523 ? Seems duplicative

Yes, #2524 and #2523 are the same registry-only nvcre component. I started this work on #2519, then split it: validator checks stayed on #2519, Helm/registry moved here. #2524 matches #2523, with a few extra tests (ownsCRDs audit, overlay/mixin pin so CRE stays opt-in).

Jayson already filed the ADR as #2541. I am fine keeping either implementation PR (#2523 or #2524) and closing the other so we can move on.

[mchmarny]

Request changes: 1 prior MAJOR remains against 4003a42. Required reviewed-SHA checks pass; the branch is behind the base branch.

[rorajani]

Rebased onto main for the up-to-date gate and pushed the remaining CodeRabbit items Mark flagged as the leftover MAJOR.

4003a429 → fccfc71f

• Health check: (status.readyReplicas == spec.replicas) and spec.replicas > 0
• Catalog: valid --set-json cre:manager.affinity=... JSON

Please re-review fccfc71.

[rorajani]

Force-pushed: aa8598f9 → fc3f4d8c. The rebase onto main was required — the branch had a conflict in the generated docs/user/container-images.md, and because GitHub could not compute a merge commit, none of the pull_request-triggered workflows were dispatching at all. They are running again on this head.

Also bumped the chart pin from v0.1.0 to v0.2.0-rc.2. The supply-chain gap this component was flagged on is fixed in v0.2.0, which ships SLSA provenance and Sigstore attestations; pinning the RC now exercises the pipeline against the real release artifacts instead of bumping blind on release day. I will move this to the v0.2.0 tag once it is cut on Monday — that is a one-line change on top.

Re-audited the CRDs per the procedure in ownscrds_audit_test.go, since bumping defaultVersion re-arms that gate: the same seven nvcre.nvidia.com CRDs ship, no other registry component claims those names, and none uses spec.conversion.strategy: Webhook, so ownsCRDs stays true. helm show crds output is byte-identical to v0.1.0 apart from the digest line — the RC changes packaging, not the API.

Worth noting for the ADR discussion: that byte-identical CRD schema also means v0.2.0-rc.2 does not close the two execution-safety gaps. There is still no field bounding the total node count a Certification selects, and still no whole-run deadline — only timeoutPerJob. AICR keeps enforcing both at the call site (target.nodeNames for the footprint, its own delete for the deadline).

[mchmarny]

Approve: no new findings against fc3f4d8; 1 prior finding obsolete. Required reviewed-SHA checks and focused registry tests pass; regenerated NVCRE BOM data matches.

[rorajani]

@mchmarny sorry to bounce this back to you right after your approval — re-approval needed, and no code changed.

Force-pushed: fc3f4d8c → 626ca620. This was a rebase only. main moved 21 commits after your review (the OKE RDMA/gpuStack work), which put the branch behind the strict up-to-date gate and re-conflicted the generated docs/user/container-images.md. Because dismiss_stale_reviews_on_push is on, there is no way to satisfy the up-to-date requirement without dropping the approval, hence the ask.

What actually changed between the two heads:

• Nothing hand-written. Diffing the PR against main before and after the rebase is byte-identical except one hunk-header line number, which shifted only because main's registry.yaml grew a line above ours.
• docs/user/container-images.md regenerated via make bom-docs on top of the new main, so it now carries OKE's images alongside ours. Our contribution to it is unchanged: one component row and one image, 45 components / 102 unique images.

Verified on 626ca620: go test -race ./pkg/recipe/... passes (including TestCommittedBOMVersionsMatchRegistry and TestOwnsCRDsPinsMatchAuditedVersions) and make lint is clean at 0 issues, both with the pinned helm v4.2.4 so the BOM renders exactly as CI does.

Enabling auto-merge (squash) so this lands as soon as you re-approve and the gate goes green, rather than sitting and going stale again. The pin moves v0.2.0-rc.2 → v0.2.0 in a small follow-up PR once the tag is cut Monday.
