Summary

nvcrectl workflow render --platform nscale --gpu-arch {b200,gb300} rejected nscale because LoadEmbeddedNodes builds its synthetic node from the embedded mocks under pkg/render/nodes/<platform>-<arch>.yaml and no nscale mocks existed. This adds nscale-b200.yaml / nscale-gb300.yaml (carrying the nscale:// providerID and the matching nvidia.com/gpu.product label, mirroring the existing nscale fixtures) and derives the --platform help text from platform.NamesList() so it cannot drift again (it was missing togetherai, nscale, and akamai). The --gpu-arch mock-templates hint gains b200. Also adds the akamai mock node so workflow render --platform akamai no longer fails with no mock nodes.

Closes #538

Type of Change

• Bug fix

Component(s) Affected

• CLI (nvcrectl)

Testing

• Verified against current main: pkg/render and the related packages pass, and workflow render works for akamai-rtxpro6000, nscale-b200, and nscale-gb300 (maintainer-verified).
• TestListAvailable golden (pkg/render/testdata/list-available/default/expected.json) updated with the new entries; change is data-only plus a string-concat help text using the existing platform.NamesList() helper (same pattern as pkg/certification/certification.go).
• Commits are signed off for the DCO (git commit -s)

📝 Walkthrough

The change adds embedded mock node templates for Nscale B200 and GB300 and Akamai RTX PRO 6000 GPUs. It updates the --platform help text to use platform names returned by nvcreplatform.NamesList(). It adds b200 to the mock-template architectures shown in the --gpu-arch help text and updates the CLI reference with the added platform and architecture options.

Full details: Linked Issues check

Explanation

#538 requires offline workflow render support for every catalog platform/architecture pair with overrides. This PR adds the three named mocks and derives the platform help text from platform.NamesList(). The reviewed node set still has no togetherai or forge mock, and no fallback to render.SyntheticProviderID is added. The supplied issue objectives identify both platforms as still unsupported.

Resolution

Implement offline workflow render support for the remaining catalog pairs, including togetherai and forge, by adding matching embedded mocks or by adding the required render.SyntheticProviderID and GPU-product fallback. Add automated tests for the supported pairs.

Thanks for this. The nscale mocks themselves look right: workflow render --platform nscale --gpu-arch {b200,gb300} now detects platform nscale with the correct architecture and applies nscale-gated overrides. Two things need to change before merge.

1. Two render goldens are stale, so go test ./pkg/render/ fails

--- FAIL: TestRenderErrors/render-errors/bad-platform-gpu
--- FAIL: TestRenderErrors/render-errors/no-flags

Both goldens embed the available: ... list that listAvailable() builds from pkg/render/nodes/, so adding the two mocks changes them too:

• pkg/render/testdata/render-errors/bad-platform-gpu/expected.json
• pkg/render/testdata/render-errors/no-flags/expected.json

Regenerating them with TESTUTIL_UPDATE_EXPECTED=true go test ./pkg/render/ should add nscale-b200, nscale-gb300 to the list and change nothing else.

2. akamai is no longer blocked, and Closes #538 would close the issue with it unfixed

#537 has merged, so the reason for leaving akamai out no longer holds. With this branch merged onto current main, nvcrectl workflow render --platform akamai --gpu-arch rtxpro6000 still fails with no mock nodes for akamai-rtxpro6000. #538 lists that pair explicitly, but Closes #538 closes the issue as soon as this merges, whatever the follow-up plan is. Either:

• add pkg/render/nodes/akamai-rtxpro6000.yaml here, with a linode:// providerID and the NVIDIA-RTX-PRO-6000-Blackwell-Server-Edition label, same as gcp-rtxpro6000.yaml, and update the three goldens above to match; or
• change Closes #538 to Refs #538 so the issue stays open for the follow-up.

Nits (non-blocking)

• No render test for the new mocks. pkg/render/testdata/render/ already has embedded-aws-h100 and embedded-onprem-{b300,gb300}. Adding embedded-nscale-b200 and embedded-nscale-gb300 would show that each mock detects as platform nscale with the right architecture and that an nscale-gated override applies. list-available only shows that the files exist.
• The --platform help now lists platforms that still fail offline. It prints togetherai, forge, akamai, but --platform forge --gpu-arch gb300 (for example) still fails with no mock nodes. Deriving the list from NamesList() is what #538 asked for, so this is fine for now. The other option #538 offers, falling back to render.SyntheticProviderID plus the nvidia.com/gpu.product label when no mock exists, would close the gap for every platform. That fits the follow-up.
• The mock templates: list in --gpu-arch is still hardcoded. b200 was added by hand, which is the same kind of drift the NamesList() change removes for --platform. Building it from listAvailable() (the arch suffixes, deduplicated) would keep it in sync.

[akhil9tiet]

@kaynetu Both done:

1. Goldens regenerated with TESTUTIL_UPDATE_EXPECTED=true go test ./pkg/render/ — only the available list changed, adding akamai-rtxpro6000, nscale-b200, nscale-gb300 (the two render-errors goldens plus the list-available golden).
2. Added pkg/render/nodes/akamai-rtxpro6000.yaml with a linode:// providerID and the NVIDIA-RTX-PRO-6000-Blackwell-Server-Edition label, so Closes #538 stays valid.

go test ./pkg/render/... passes clean.

Thanks @akhil9tiet for turning these around so quickly, and for regenerating the goldens and adding the akamai mock. I checked against current main: pkg/render and the related packages pass, and workflow render now works for akamai-rtxpro6000, nscale-b200 and nscale-gb300. 🙏

Two small things, if you don't mind:

1. PR description. It still says akamai is out of scope because feat: add Akamai RTX PRO 6000 TCP overlays #537 is open, and that go test couldn't be run. Both are out of date now. Since this repo squash-merges, it would be nice to refresh the description so that text doesn't end up in the commit message.

2. togetherai and forge (follow-up, not for this PR). The catalog has overrides for both platforms, but neither has a mock yet, so workflow render --platform togetherai|forge still fails with no mock nodes. That was already the case before this PR, so no need to handle it here. Because [Bug]: nvcrectl workflow render has no mock nodes for akamai or nscale #538's Expected section covers it and Closes #538 will close the issue, would you be up for opening a follow-up issue for the SyntheticProviderID fallback [Bug]: nvcrectl workflow render has no mock nodes for akamai or nscale #538 describes? That way workflow render could handle any platform without needing a mock for each pair.

Thanks again!

[akhil9tiet]

Description refreshed — the akamai-out-of-scope and go-test lines are gone, since this repo squash-merges. On the follow-up issue for the SyntheticProviderID fallback, I'll check and get back to you.

I built this head and ran it rather than just reading it. workflow render --platform nscale --gpu-arch b200, --gpu-arch gb300 and --platform akamai --gpu-arch rtxpro6000 all render, each annotating detected-platform and detected-gpu-architecture correctly, and go test ./pkg/render/ passes. The three mock YAMLs match their siblings byte for byte in shape, and the nscale:// and linode:// prefixes are exactly what nodePlatform switches on at pkg/controller/workflow_detect.go:63 and :65. platform.Names() returns a slice literal at pkg/platform/platforms.go:32, so NamesList() ordering is deterministic and the two goldens that embed ValidateFlag's message are generated from the same helper. The golden updates are pure data. This is good as is.

One leftover, the same drift this PR exists to remove. docs/cli-reference/workflow.md:21 still carries the hand-written list aws, gcp, azure, oci, mistral, onprem, forge, which is the literal pkg/render/render.go:98 just dropped. The binary built from this head prints aws, gcp, azure, oci, onprem, togetherai, mistral, forge, nscale, akamai. The sibling pages already list all ten: docs/cli-reference/certification.md:93 and docs/cli-reference/workloadrun.md:72. Line 22 of the same page is stale the same way, listing mock templates h100, b300, gb200, gb300, rtxpro6000 without the b200 this PR adds to the flag hint, and nscale-b200 now exists. Worth copying the ten-name list from certification.md:93 onto line 21 and adding b200 to line 22.

[akhil9tiet]

@ndipebot Good catch — docs/cli-reference/workflow.md:21 now carries the ten-platform list from certification.md:93, and line 22 adds b200 to the mock-template list, matching the flag hint this PR introduces.

Do not advertise TogetherAI for offline workflow rendering.

validateFlags accepts --platform togetherai --gpu-arch b200. The offline path then requires nodes/togetherai-b200.yaml, which is absent, and returns no mock nodes for togetherai-b200. The CLI documentation advertises the same unsupported platform.

Add TogetherAI mock or fallback support, or remove togetherai from both the generated help and docs/cli-reference/workflow.md.

In reply to CodeRabbit's review above ('Do not advertise TogetherAI for offline workflow rendering') — no change here: TogetherAI stays listed intentionally. It's one of the platform values the controller's detection returns (pkg/platform/platforms.go), and the CLI flag help derives from that same set so help text and accepted values can't drift apart — it must stay accepted for --dry-run (online) mode too. Mock templates only cover the platform+arch combos listed in the docs; a missing combo fails loudly with 'no mock nodes for X-Y' plus the available list, so nothing is silently misrepresented. Removing it from help/docs would break the help/acceptance invariant.

[ndipebot]

Both lines I flagged are fixed properly. I built nvcrectl at 05881eb4 and compared workflow render --help to the table: the --platform row is the ten names from platform.Names() in the same order, and the --gpu-arch mock list matches the architectures that actually exist across pkg/render/nodes/, which I derived from the file names rather than from the help string. certification.md:93 and workloadrun.md:72 carry the same ten names, so the three pages agree.

The merge from main only touched docs/cli-reference/workflow.md on the PR side, so nothing of yours was clobbered. go test ./pkg/render/... ./pkg/platform/... ./test/docspolicy/ passes at the head, and nscale-b200, nscale-gb300 and akamai-rtxpro6000 each render with the right detected-platform and detected-gpu-architecture annotations.

One documentation-only thought, left inline, about togetherai and forge on this particular page.

Also worth a follow-up rather than a change here: nothing pins either doc line, which is the same drift this PR exists to remove. A small test/docspolicy case asserting the --platform row equals platform.NamesList() and the arch row equals the set derived from pkg/render/nodes/ would stop the next platform constant from re-opening it. Want me to file that?

Thanks for verifying against the built binary. Keeping this PR scoped to the drift fix — noting the docspolicy test idea as a follow-up, no need to file an issue for it.
