fix(onboard): keep the Docker reason in GPU-mode probe failures by Dongni-Yang · Pull Request #11280 · NVIDIA/NemoClaw

Dongni-Yang · 2026-09-09T07:55:25Z

Problem

When Docker rejects every GPU mode during managed-bootstrap sandbox creation, selectedDockerMode throws with each attempt's Docker error appended by formatDockerGpuModeFailureDetails. That function sliced each attempt to 240 characters and the joined detail to 1200, with no marker. Docker's own message repeats the digest-pinned image reference (about 114 characters each) and puts the reason last, so for NemoClaw's normal ghcr.io/nvidia/nemoclaw/<image>@sha256:<64 hex> references the two references alone filled the budget, and the reason (registry auth, network, manifest not found) was cut mid-digest with no indication. The reporter's Jetson log shows exactly that.

Change

src/lib/onboard/managed-bootstrap/docker-runtime.ts:

Abbreviate @sha256:<64 hex> to @sha256:<12 hex>... inside the attempt error, after redaction, so the budget goes to the reason. The full reference is still printed by the surrounding onboarding output.
Collapse whitespace so each attempt is one line.
Replace the silent prefix slice with clampDiagnostic: when the text exceeds the budget it keeps the head and the ending and inserts ... [N characters omitted] .... Docker puts its reason last, so the ending is the part worth keeping.
Budgets: 400 per attempt (tail 120) and 1600 for the joined detail (tail 400), as named constants next to the function.

No other caller uses this function. The GPU-patch diagnostics summary records full attempt errors separately and is unchanged.

Verification

src/lib/onboard/managed-bootstrap/docker-runtime.test.ts, two new cases. Both fail on main and pass here:

The reporter's shape: an error with three full digest-pinned references and a trailing Error response from daemon: manifest unknown reason. Before: expected ' Attempts: --gpus all: Unable to find…' to contain 'Error response from daemon: manifest …'. After: the reason is present, digests are abbreviated, the full digest is absent, and no omission marker appears because the text now fits.
An over-long error: the marker ... [N characters omitted] ... appears and the trailing reason survives. Before: the text ended at 240 characters with no marker.

The existing redaction case is unchanged and passes (12 of 12 in the file). npm run typecheck:cli, oxlint, and oxfmt --check are clean. Pre-commit and pre-push hooks ran.

This is pure string formatting, so no Jetson hardware is needed; the Jetson path and the generic compatibility path share this function.

CodeRabbit on `44a3becabe`, and what changed in `41cae13230`

Rendered diagnostic exceeded limit by the marker length. Fixed. clampDiagnostic now reserves the omission marker at its widest before choosing the head, so a clamped attempt stays within 400 characters after its label and the joined detail within 1600. Two boundary assertions in docker-runtime.test.ts cover one attempt and six joined attempts; both fail on 44a3becabe and pass on 41cae13230. The last attempt's reason still survives the joined clamp.
Docstring-coverage warning on the touched functions. Taken in 87c1e1fa06. One-line docstrings for the digest abbreviation, the exported formatter, and the test helper; no behavior change.

Advisor findings on `87c1e1fa06`, and what changed in `d4697a228c`

All nine specialists completed; eight found no issue.

Verification: no caller-to-throw proof. Fixed in d4697a228c. New case in docker-runtime.test.ts: every GPU-mode probe rejects with a digest-pinned "Unable to find image" error carrying a token, and createDockerManagedBootstrapSurface().createLifecycle(input) throws the managed-bootstrap message containing the Docker reason, the abbreviated digest, and token=<REDACTED>, with at least two probes attempted. Against the formatter on main the reason is absent, so the case is red there and green here.

Summary by CodeRabbit

Bug Fixes
- Improved Docker GPU setup error messages by shortening lengthy image digests and normalizing whitespace.
- Long diagnostics now preserve both the beginning and end of messages while indicating omitted content.
- Preserved the underlying Docker failure reason through related setup errors.
- Sensitive credentials are redacted from displayed diagnostics.
- Added limits to prevent individual and combined failure details from becoming excessively large, keeping displayed diagnostics readable and within safe length bounds.

@sha256

`formatDockerGpuModeFailureDetails` sliced each attempt's Docker error to 240 characters with no marker. Docker repeats the digest-pinned image reference in its own message and puts the reason last, so for NemoClaw's `ghcr.io/nvidia/nemoclaw/<image>@sha256:<64 hex>` references the two references alone filled the budget and the reason was cut mid-digest. Abbreviate `@sha256:<64 hex>` to twelve hex characters after redaction, collapse whitespace, and clamp over-long text by keeping its head and its ending with an explicit `[N characters omitted]` marker. Budgets are 400 per attempt and 1600 for the joined detail. Two new tests fail on the previous implementation: the reporter's three-reference message now keeps `Error response from daemon`, and an over-long error keeps its trailing reason behind the marker.

📝 Walkthrough

Walkthrough

The Docker GPU failure formatter now abbreviates digest-pinned image references, normalizes whitespace, preserves message endings, reports omitted characters, and enforces per-attempt and aggregate length limits. Tests cover these behaviors.

Changes

Docker GPU diagnostics

Layer / File(s)	Summary
Formatter normalization and length limits `src/lib/onboard/managed-bootstrap/docker-runtime.ts`	The formatter abbreviates digests, normalizes failure text, preserves message endings, reports omitted characters, and limits individual details to 400 characters and combined diagnostics to 1,600 characters.
Formatter behavior tests `src/lib/onboard/managed-bootstrap/docker-runtime.test.ts`	Tests cover failed GPU mode attempts, digest formatting, whitespace normalization, truncation markers, preserved endings, credential redaction, lifecycle failures, and output limits.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to d4697

GPU bootstrap failures now retain useful Docker failure reasons while abbreviating digests, redacting credentials, and bounding diagnostic output. No current merge-blocking risk remains.

…#11197) `clampDiagnostic` appended the omission marker after keeping `limit` characters, so a clamped attempt rendered past the 400-character budget and the joined detail past 1600. Reserve the marker at its widest before choosing the head, so the rendered text never exceeds the limit. Two boundary assertions: one clamped attempt stays within 400 characters after its label, and six over-long attempts stay within 1600 while the last attempt's reason survives.

…#11197) The three formatter cases call `formatDockerGpuModeFailureDetails` directly. Add the caller-path proof: with every GPU-mode probe rejecting on a digest-pinned image error, `createLifecycle` throws the managed bootstrap message with the Docker reason, the abbreviated digest, and the redacted token. Against the previous formatter the reason is missing. Signed-off-by: Dongni Yang <dongniy@nvidia.com>
