📝 Summary

Summary by CodeRabbit

  • Updates
    • Default container images and Helm charts are available through NVIDIA NGC repositories.
    • TAS lab setup pulls a configurable published image instead of building one locally.
    • Releases use dedicated version branches and require internal security approval before public promotion.
  • Documentation
    • Kubernetes installation instructions and artifact verification guidance reflect NGC locations, checksums, and attestations.
    • Release and chart-publishing guidance describes the updated release process and NGC distribution.

Publishing workflows and distribution references now use NGC. The TAS lab setup pulls a configurable image and loads it into kind. Release guidance describes version-named branches, internal approval, and unchanged artifact promotion.

Changes: NGC publishing and release process

Layer / File(s) Summary
Configure NGC publishing workflows
.github/workflows/docker.yml, .github/workflows/helm-release.yaml, .github/workflows/cleanup-untagged-images.yml, .github/workflows/release.yml, CHANGELOG.md, DEVELOPMENT.md
The Docker workflow now runs manually, validates release ref names, and authenticates to NGC. The Helm workflow pushes packaged charts to NGC and attaches checksums as OCI referrers. The former release and untagged-image cleanup workflows were removed. Project guidance records the publishing process.
Update release roles and artifact procedures
GOVERNANCE.md, RELEASE.md, SECURITY.md, scripts/create-release-tag.sh, CHANGELOG.md
Release guidance describes version-named branches, staging builds, internal security approval, unchanged artifact promotion, and verification. Governance limits release management to an eligible NVIDIA release manager. The tag script resolves the matching branch and tag ref.
Update chart defaults and distribution references
charts/topograph/values.yaml, charts/topograph/tests/*, charts/topograph/README.md, README.md, docs/*, SECURITY.md
The chart default and related tests use the NVIDIA NGC image. Installation and distribution references use the NGC Helm repository and image. Security instructions update artifact locations and attestation references.
Pull and configure the TAS lab image
demos/tas-lab/versions.env, demos/tas-lab/README.md, demos/tas-lab/setup/*, demos/tas-lab/teardown/teardown.sh
The TAS lab setup reads the configured image URL and tag, pulls the image, loads it into kind, and passes its repository and tag to Helm installation. Setup and teardown instructions use the configured image reference.

The release is mergeable with follow-up on two documentation errors: the TAS image-removal command needs its variables loaded, and the changelog should name the configured image destination.

[High impact] The PR changes how Topograph artifacts are built, reviewed, and delivered to all users.

Remove the extra tag-triggered image build before merging so releases publish only the approved image.

Summary

Moves image and Helm chart builds to NGC staging and updates public installation addresses.

  • Topograph images publish to NGC for public use.
  • Helm charts and their checksums publish through NGC OCI.
  • Releases pass internal review before approved artifacts reach the public repositories.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Handle a repeat publication of the same chart version.

A second manual run packages the same chart version and attempts to push it again. NGC rejects an existing chart version, so a publication retry fails. Check the published version before pushing. Skip an identical version, and report a mismatch rather than treating it as a successful retry. (raw.githubusercontent.com)

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Align the published chart with the release image.

The packaged chart defaults to ghcr.io/dsx-ai-factory/topograph, but the Docker workflow publishes new release images to nvcr.io/nvstaging/topograph/topograph. A new chart version can publish successfully while its default image cannot be pulled. Update the chart’s default image repository before publishing it to NGC. If that NGC image requires authentication, document the required imagePullSecrets configuration. (raw.githubusercontent.com)

Pin the Helm push plugin to immutable content.

--version v0.10.4 selects a tag-based third-party dependency. The later helm cm-push step runs this plugin with NGC_API_KEY. A compromised or retagged release could read the key and publish or exfiltrate artifacts. Install from immutable content and verify its checksum. (github.com)

67-68: Avoid failing on a repeated chart version.

A rerun pushes the same topograph version again. NGC can reject the existing version, so a retry fails instead of confirming or skipping an identical artifact. Check the published version before helm cm-push, and fail on a content or version mismatch.

DEVELOPMENT.md: 1

185-188: 📐 Maintainability & Code Quality

The Docker workflow is manual-only, but a manual dispatch can target a release tag. Its tag-specific validation confirms that this path is supported. The documentation does not state that a tag push automatically triggers publication, so the claimed inconsistency is not established.

Align the NGC image namespace with the documented release path.

The workflow publishes to 1070195845945670/topograph/topograph, but the release documentation and changelog identify dsx-ai-factory-staging/topograph/topograph. Use one namespace across the workflow and release references.

Load the image variables before the removal command.

After the documented setup, TOPOGRAPH_IMG_URL and TOPOGRAPH_IMG_TAG are not set in the reader’s shell. The copied docker rmi command therefore uses an invalid image reference.

Thanks for carrying the new nvcr.io/nvidia/topograph/topograph default through the chart tests, snapshots and install docs in one pass.

The Docker and Release Helm Charts workflows now publish through the ngc-publish environment with NGC_API_KEY (helm cm-push replaces the gh-pages index), and the tas-lab demo pulls a published image instead of building one from the checkout. The Helm checksum verification in SECURITY.md is still commented out behind its TODO, so that section needs a follow-up once NGC has a place for the .sha256 file. #614 and #612, opened since, add cosign signing and OCI chart publishing on ghcr.io/dsx-ai-factory/topograph, while this moves both artifacts to NGC, so the two release plans need reconciling, whether that means signing on nvcr.io or publishing to both registries.

  • Deleting RELEASE.md leaves both SECURITY.md links to it dangling (the release procedure here and the one under Supported Versions), along with five in GOVERNANCE.md: release authority, version format, cadence, and the published-artifact locations at lines 277 and 317 that the deprecation policy relies on. Either keep a trimmed RELEASE.md for the NGC flow or repoint those references in this PR; lychee only checks docs/**, so CI will not catch them. (SECURITY.md:109)

    topograph/SECURITY.md

    Lines 107 to 109 in ce845a4

    Topograph does not currently publish a detached cosign signature or a GPG-signed release manifest.
    The Sigstore-backed provenance attestations and the chart checksum are the verification path
    today. The full release and verification procedure is documented in [RELEASE.md](./RELEASE.md).
    CodeRabbit flagged this too.

TOPOGRAPH_IMG_TAG defaults to v1.1.0, which is not published: the newest tag is v1.0.0, nvcr.io/nvidia/topograph/topograph:v1.1.0 returns 404, and the tas-lab*.yaml models from #580 are in no released image, so a default setup/topograph.sh install fails at docker pull. Keeping the build-from-checkout path as the default, or as the fallback when no tag is set, keeps the lab working until a release that embeds these models ships.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Publish the generated checksum with the chart.

The workflow creates packaged/topograph-*.tgz.sha256, but the publication loop sends only the .tgz to HELM_REPOSITORY. The PR also removes the previous publication of the complete packaged directory. The NGC chart can therefore be published without the checksum required by the active release contract, so checksum comparison cannot be completed.

Add the supported NGC upload for ${chart}.sha256. This fixes the NGC publication gap; it does not by itself resolve the separate stale or commented-out instructions in SECURITY.md.

The claim that container provenance is published to NGC is supported by the Docker workflow. The comment's concern that this is unconfirmed does not hold. No change is needed at CHANGELOG.md line 48.

The workflow sets the registry to nvcr.io and the image name to 1070195845945670/topograph/topograph. It builds with provenance: mode=max,version=v1 and pushes the image to that registry. A separate actions/attest step then runs with push-to-registry: true against the pushed image digest. Both provenance paths target the NGC registry.

228-230: The Docker workflow entry is still stale.

.github/workflows/docker.yml uses manual dispatch and publishes to nvcr.io, but these lines still describe tag-push triggering and GHCR publication. Update the entry to match the current workflow.

Needs changes: 2 blocking issues.

  • SECURITY.md:86: This verification cannot pass for any image the Docker workflow builds: its provenance will always name a release-* branch, never refs/tags/vX.Y.Z. The chart command at line 98 has the same problem.
  • .github/workflows/helm-release.yaml:17: The ngc-publish environment that now guards NGC_API_KEY has no required reviewers, allows admin bypass, and nothing restricts who can create release-* branches or v* tags.

Notes

Question, not a request for this PR: since nvcr.io is OCI 1.1, could the chart also be pushed as OCI (helm push oci://nvcr.io/..., built into Helm 3.8+, no plugin) alongside cm-push? That gives the chart a registry digest for actions/attest push-to-registry and future cosign signing, the same as the image, and would remove the tag-pinned helm-push plugin. NGC's docs only show cm-push and ngc registry chart push, so I don't know whether NGC serves OCI charts. Second question: release.yml's gates (tag format, Chart version and appVersion matching the tag, CHANGELOG release notes) go away with it, and RELEASE.md:128-130 moves chart preparation to the internal process; is that process meant to own those checks now?

issue (blocking): The ngc-publish environment that now guards NGC_API_KEY has no required reviewers, allows admin bypass, and nothing restricts who can create release-* branches or v* tags.

Any collaborator with write access (including the external maintainers RELEASE.md:20-21 excludes from releasing) or a stolen write token can push a release-x branch whose own workflow declares environment: ngc-publish and run it. That job receives NGC_API_KEY and can push arbitrary images or charts into the staging org that promotion publishes from, or exfiltrate the key. If NGC_API_KEY is a repository secret rather than an environment secret, a workflow on any branch can read it.

Before the first release through this path: require reviewers on ngc-publish limited to release managers, turn off admin bypass, add a ruleset restricting who can create or update release-* branches and v* tags, and confirm NGC_API_KEY is stored only as an ngc-publish environment secret. The same environment gates docker.yml:21.

The settings are your call. Two small things so this doesn't get lost if the org opens up:

  • docker.yml:35 only checks the version when the ref name starts with v, so a dispatch from main or any other branch skips it and pushes main and short-SHA tags to the staging org. Running the check on every dispatch, and adding the same check to helm-release.yaml, refuses anything but a vX.Y.Z branch. That guards against mistakes, not a write-access user, who can edit the workflow on their own branch.
  • For that case, a line in RELEASE.md near the release-manager list, such as "before granting write access to anyone outside the release managers, require reviewers on ngc-publish and disable admin bypass", keeps it from being forgotten.

P1 Tags publish an unapproved rebuild

Pushing the final release tag starts docker-gh.yml, which builds and publishes a fresh image to GHCR. The new release process requires publishing the exact approved image without rebuilding, and RELEASE.md explicitly says tagging does not rebuild artifacts. This extra image is not the one reviewed in staging.

Remove the tag-triggered build, or make any GHCR publication copy the approved image instead.
