Conversation
The Docker reachability probe ran `docker version` in a four-name environment (HOME, USER, LOGNAME, PATH), while every Docker command the CLI runs afterwards gets the full subprocess allowlist. On a host whose daemon answers only through one of the dropped names, the probe reports the host's default authority unreachable, detection falls through to the socket candidates, and the CLI pins DOCKER_HOST to Podman's rootless socket. Preflight then reports Docker unreachable and names the docker group, so onboarding stops before its first step on a host whose Docker is healthy. Probe with the allowlist real commands get, keep the authority under test pinned, hold the host default when a probe reaches no verdict (a spawn failure or a timeout is not an observed refusal), and put the Docker sockets — including the rootless one — ahead of Podman's in the Linux candidate order. The probe now reads the shared subprocess allowlist, which raises the recorded fan-in of `src/lib/subprocess-env.ts` by one. Refs #10367 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

`buildDockerProbeEnv` forwards the proxy names now, but skipped the `withLocalNoProxy` augmentation that `buildSubprocessEnv` applies to every Docker command the CLI runs. A host with `HTTP_PROXY` set and a local `tcp://` authority could therefore route the probe through the proxy while the real commands went direct, so the probe could report an authority unreachable that every later command reaches — the same defect class this branch fixes. Fold the separate probe-environment test into the default-authority fixture that already owns this boundary, and let that one fixture pin the Docker context, the runtime directory, the proxy exclusions, and the credential boundary together. Also correct the Linux candidate-order comment: order decides only between candidates of the same engine identity, because two engines that both answer still abort the selection.

Addressed the automated review on PR Review Advisor — migration completion (blocker) and operations. Both found the same gap: PR Review Advisor — test design. Folded the second Docker CLI fixture into the existing default-authority one. That single fixture now pins the Docker context and config, the runtime directory, the proxy exclusions, and the credential boundary together. The inconclusive-probe test stays separate, as recommended. PR Review Advisor — code reduction. Kept CodeRabbit — merge risk on the mixed-identity bail. Real, and pre-existing: |
The inconclusive branch is the load-bearing half of the fix, but only its consequence was tested, through an injected probe. Drive the real probe with a Docker CLI that dies without an exit status — the same shape the probe timeout produces — while a Podman socket answers right after it. Without the branch, detection selects that socket. Correct two claims in the explanatory text. `XDG_RUNTIME_DIR` does not select a rootless daemon socket for the Docker CLI; the verifiable mechanisms are `SSH_AUTH_SOCK` for an `ssh://` context and the proxy names for a `tcp://` one, and the general contract is that the probe predicts what the real commands do and must not ask under a narrower environment. Also name the third inconclusive case, an answer too large for the probe buffer, and record that the timeout now biases toward holding the host default.

CI note for reviewers: Worth noting for anyone reading the check list: two other workflow runs on the same commit report For completeness on why the change itself cannot slow that suite: detection now returns immediately when the ambient probe reaches no verdict, instead of scanning candidate sockets, and the scan is unchanged otherwise. The change can only remove probe work, never add it. |

Advisor findings on Migration completion — a second Docker authority selector. Real, and filed as #10632. This is the strongest finding of the round, and it is genuinely out of scope here. Test design — duplicate no-verdict tests. Valid; a two-line deletion whenever you want it. Code reduction — probe environment duplicates Five other specialists reported no finding. |

Advisor findings on Also: your Operations, filed as #10645 rather than fixed here. The mechanism is real: preflight runs What makes it a follow-up rather than a blocker is that the call is byte-identical on This PR does not touch preflight. What it changes is which authority preflight ends up querying in one case: previously a hung default plus a discovered socket meant detection redirected to that socket, so preflight answered quickly against a runtime the host never chose — the #10367 defect. Now the hung default is correctly kept, so the missing bound becomes visible. The right fix is to bound preflight and give the timeout its own diagnostic, which needs its own tests and its own failure semantics. Behavior — no selection test for the rootless Docker socket. Valid, and it is my gap. I added it("selects the rootless Docker socket when the default authority is unreachable (#10367)", () => {
// The rootless daemon's socket shares Podman's runtime directory and was
// never a candidate before. Listing it is not enough: detection has to
// actually adopt it, ahead of the Podman socket beside it.
const rootlessSocket = "/run/user/1000/docker.sock";
const podmanSocket = "/run/user/1000/podman/podman.sock";
const sockets = new Set([rootlessSocket, podmanSocket]);
expect(
detectDockerHost({
env: {},

});Say the word and I will push it, together with the duplicate no-verdict test deletion from the previous round, in one commit. Seven other specialists reported no finding. |

Summary
NemoClaw probes Docker reachability by running
docker versionin a four-name environment (HOME,USER,LOGNAME,PATH), but every Docker command it runs afterwards gets the full subprocess allowlist. On a host whose daemon answers only through one of the dropped names, the probe reports the host's own default authority unreachable, detection falls through to the socket candidates, and the CLI pinsDOCKER_HOSTto Podman's rootless socket. Preflight then reportsDocker is not reachableand points at the docker group, so onboarding stops at its first step on a host whose Docker is healthy. After this change the probe asks the same question the later commands answer, and detection never redirects the CLI on no evidence.Related Issue
Closes #10367
This removes the mechanisms that produce the reported outcome: a probe environment narrower than the one the predicted commands run in, and a probe that reaches no verdict counting as a refusal. Either can send
DOCKER_HOSTto Podman's socket on a host whose Docker daemon is live.One honest caveat for whoever merges this. The reporter runs a DGX Spark with Docker and Podman installed; I have no such host and they have not yet answered the two diagnostic commands I asked for on the issue, so the cure is reasoned from the code path, not observed on their machine. If their
docker versionunder the old four-name environment turns out to exit0quickly, neither fix explains their failure and the issue should be reopened rather than left closed. Two details from the report stay out of scope either way: the docker-group remediation text that names the wrong cause, and thedocker infoversusdocker versiondisagreement on an unhealthy daemon.Changes
buildDockerProbeEnvnow selects names withisSubprocessEnvNameAllowed, the same allowlistbuildSubprocessEnvgives real Docker commands, and drops an ambientDOCKER_HOSTso the probe still pins the authority under test. The probe predicts whether those commands reach a daemon, so it must not ask under a narrower environment:SSH_AUTH_SOCKauthenticates anssh://Docker context and the proxy names decide how atcp://one is routed. (An earlier revision of this description claimedXDG_RUNTIME_DIRselects a rootless daemon socket for the Docker CLI. I tested that and it is false — the CLI ignores a listeningdocker.sockin the runtime directory — so the justification is corrected here and in the code comment.)probeDockerHostreportsinconclusivewhen the Docker CLI cannot be spawned or the 3-second probe timeout kills it, anddetectDockerHostholds the host default in that case. A probe that never answered is not an observed refusal, so it must not move the whole CLI to a fallback socket./run/docker.sock,/var/run/docker.sock,/run/user/<uid>/docker.sock, then Podman's. Rootless Docker's socket sits beside Podman's in the same runtime directory and was never a candidate.buildDockerProbeEnvalso applieswithLocalNoProxy, whichbuildSubprocessEnvgives every real Docker command. Without it, forwarding the proxy names could route a probe of a localtcp://authority through a host proxy that the real commands bypass — the same defect class, reintroduced by the fix.ci/source-architecture-budget.json: reading the shared allowlist raises the recorded fan-in ofsrc/lib/subprocess-env.tsfrom 24 to 25.docker infoanddocker versionpreflight calls at 15 seconds, so preserving an inconclusive default authority cannot leave onboarding waiting without a limit.Risk family
src/lib/platform.tsputs this PR in the tier-3platform-installfamily, whose required job iscloud-onboard. That workflow has nopull_requesttrigger, so it selects on the post-merge push tomainrather than here. Say the word if you want acloud-onboardrun before merge and I will arrange it.Not in this PR
CodeRabbit's merge-risk note and the PR Review Advisor both point at the mixed-identity bail: when the default authority is dead and both a Docker socket and a Podman socket answer,
detectDockerHostreturnsnulland the CLI keeps its dead default. That path is pre-existing and unchanged here, and removing it reverses a decision recorded in #8823 and #10253, whose security review cited it as a pass criterion. It is a maintainer call, so it is a separate stacked PR — #10387 — with the reversal argued. This PR leaves the guard exactly as it was.Type of Change
