Outcome

nemoclaw <sandbox> status now probes the host port the managed vLLM container actually publishes, so a sandbox onboarded with a custom NEMOCLAW_VLLM_PORT reports its healthy backend as reachable instead of unreachable. Every other locally derived vLLM URL follows the same published binding.

Reason

VLLM_PORT is parsed once from this process's environment when src/lib/core/ports.ts loads, so it carries the override only for a shell that exports it. A status call made from any other shell fell back to the default 8000 while the container published, for example, 0.0.0.0:46145->8000/tcp, and reported unreachable (http://127.0.0.1:8000/v1/models) for a listener that was serving normally.

The managed-endpoint recovery that would have supplied the real binding cannot cover this: it exists to prove the bearer credential, so it returns nothing for a container started without managed authentication, and the fallback below it assumed the ambient port.

Related issues

Fixes #11374

This PR delivers the status half of that report. The leftover-container half is a separate failure boundary and is not addressed here.

Changes

• src/lib/inference/serving/vllm-host-local-lifecycle.ts — add observeManagedVllmHostPort(), which reads the container's published binding for the fixed container port and validates it as a TCP port. It makes no authentication claim, and it checks the local daemon first and then the ambient Docker client configuration, matching how container ownership inspection resolves the same pair.
• src/lib/inference/local.ts — resolve the managed fallback port through that observation, falling back to the ambient value only when no managed container publishes one. The seven URLs that previously interpolated VLLM_PORT directly now share this single resolver.

Verification

• npx vitest run src/lib/inference/local-vllm-published-port.test.ts — the new test fails on the unmodified source with expected 'http://127.0.0.1:8000/v1/models' to contain ':46145', which is the endpoint string quoted in the issue, and passes with the change.
• npx vitest run src/lib/inference/local-vllm-published-port.test.ts — a second test covers a container visible only under a non-default Docker context. It fails when the observation is restricted to the local daemon and passes with both selections.
• npx vitest run src/lib/inference/ — 121 files, 2646 passed, 1 skipped, 0 failed, repeated across four consecutive runs.
• npm run validate:pr — passed on a clean tree: 17 hooks passed, 17 skipped as not applicable, 0 failed, including gitleaks (secret scan), Codebase growth guardrails, Source-shape test budget, and TypeScript (CLI).
• npm run format — applied before the final commit; the tree is clean.
• Collision search — no open PR or merged commit touches observeManagedVllmHostPort, getLocalProviderHealthEndpoint, or the VLLM_PORT fallbacks; no other PR references [All Platforms][Inference] Custom NEMOCLAW_VLLM_PORT: destroy leaks ~180GB GPU memory and status probes wrong port #11374.
• Secret review — the diff adds no credential handling and reads only a container port mapping.

Review notes

Why one resolver instead of seven fixes. The same ambient-port fallback appeared in getLocalProviderBaseUrl, getLocalProviderValidationBaseUrl, getLocalProviderHealthEndpoint, getLocalProviderAvailabilityEndpoint, the probe in probeLocalProviderHealth, and two host.openshell.internal URLs. Repairing only the status probe would have left the same defect reachable through the sibling paths, and repairing each in place would have duplicated the resolution seven times. Routing all of them through one resolver closes the class and leaves each call site a single expression.

Why recovery was not changed. recoverHostLocalManagedVllmEndpoint returns an API key and therefore must keep requiring the auth label, the exact bindings, and the credential fingerprint. Port observation is a separate concern with no credential claim, so it is a new function rather than a relaxation of that contract.

Sibling checked and excluded. ollama-local interpolates OLLAMA_PORT from the same ambient source, but Ollama is installed on the host through systemd rather than published by a NemoClaw-managed container, so there is no published binding to observe and the same repair does not apply. It is unchanged here.

Review follow-up. The first revision observed the port through the local-daemon Docker environment, which only matches a container started for an authenticated profile. An ordinary managed profile follows the ambient client configuration, so its container was missed under a non-default DOCKER_HOST or DOCKER_CONTEXT and the callers fell back to the ambient port again. The observation now tries the local daemon and then the ambient configuration, and the added test pins the non-default context.

Fork CI. openshell-sdk-package and the checks that depend on it cannot run for a fork pull request, so the local results above are the evidence for this change.

📝 Walkthrough

Walkthrough

Managed vLLM endpoint construction now discovers the published Docker host port. Local validation, health checks, availability checks, reachability checks, probes, diagnostics, and tests use the discovered port with a configured fallback.

Changes

Managed vLLM port resolution

Layer / File(s)	Summary
Docker published-port discovery src/lib/inference/serving/vllm-host-local-lifecycle.ts	Added Docker inspection for the managed vLLM container. The helper checks local-managed and ambient Docker contexts, validates the published port, and returns null when no valid binding exists.
Dynamic endpoint integration and validation src/lib/inference/local.ts, src/lib/inference/local-vllm-published-port.test.ts	Updated managed vLLM URLs and checks to use the observed published port, with VLLM_PORT fallback. Added coverage for ambient Docker-context discovery and selector attempts.

Explanation

Issue #11374 has two coding requirements. The PR satisfies the custom-port status requirement: observeManagedVllmHostPort() checks the local and ambient Docker selections, and local.ts uses the observed port for the vLLM URL paths. Regression tests cover a custom published port and an ambient-only Docker context. The PR does not satisfy the destroy requirement. The diff contains no cleanup for the standalone managed nemoclaw-vllm container and no test that verifies its removal or GPU-memory release.

observeManagedVllmHostPort() always queries buildLocalManagedVllmDockerEnv(), which forces the default local Docker context. Unauthenticated vLLM profiles are launched with buildVllmDockerEnv(), so a managed container running under an ambient DOCKER_HOST/DOCKER_CONTEXT will be missed and these callers fall back to the current VLLM_PORT. Could this probe use the same Docker selection as the runtime it is observing, with a regression for a non-default Docker context?

[sylvesterkaczmarek]

Rechecked 5557b7fc. The published-port probe now checks both the host-local managed Docker selection and the ambient runtime Docker selection, with a regression for a non-default Docker context. My previous blocker is resolved.

[HOYALIM]

Thanks — that was right. The observation forced the local-daemon Docker environment, which only matches a container started for an authenticated profile; an ordinary managed profile follows the ambient client configuration and was therefore missed under a non-default DOCKER_HOST or DOCKER_CONTEXT.

It now checks the local daemon first and then the ambient configuration, matching how container ownership inspection resolves the same pair. Added a regression covering a container visible only under a non-default context — it fails when the observation is restricted to the local daemon.

Pushed as 5557b7f. npm run validate:pr passes (17 hooks, 0 failed).

Rechecked current 5557b7fc after the new test feedback. The runtime change still looks correct, but the non-default-context regression does not actually prove the second probe uses the ambient Docker selection: its mock returns the port on call #2 regardless of env. Please make the mock conditional on the expected non-default selector so the test fails if both probes accidentally use the local daemon.

[sylvesterkaczmarek]

Rechecked current 680a16bd. The regression now makes the published port conditional on the ambient DOCKER_CONTEXT and asserts that both the pinned local default selector and the ambient selector are actually probed. That closes the test-validity issue I raised on 5557b7fc; no remaining blocker from my review.

[ericksoa]

Thank you for the fix and for following through on the Docker-context review feedback.

Closing this as superseded for the reported issue by #11528, now merged as 946fb16. That change addresses #11374 by using the sandbox's validated recorded vLLM port for diagnostics and route-repair probes, and by retiring the managed container after its last consumer is destroyed. The branch's live GPU qualification passed both custom-port lifecycle cycles, including re-onboarding after cleanup.

This PR also proposes broader Docker port discovery across seven URL-building paths. That additional behavior was not included in #11528; we are closing because the original reported bug is addressed. If a remaining failure needs that broader discovery, a concrete reproduction would let us evaluate it separately.

Thanks again for helping diagnose and improve this behavior.
