Colima exposes Docker through a persisted context and does not create /var/run/docker.sock. The OpenShell gateway reads only DOCKER_HOST, so onboarding failed with "Socket not found: /var/run/docker.sock". Select the local socket of a non-default current context when the Docker CLI default answers through it, unless /var/run/docker.sock already resolves to that socket.

On a host whose current Docker context is Colima, importing runner.ts now exports that context's socket as DOCKER_HOST. The build environment test sets DOCKER_CONTEXT but inherits DOCKER_HOST, and main now lets a nonblank DOCKER_HOST override DOCKER_CONTEXT, so the test fails on such a host once this branch is merged with main. It fails the same way on main when the shell exports DOCKER_HOST. Pin DOCKER_HOST to blank so the test checks only the variables it sets. Signed-off-by: Bowen Zhu <bowenzhu66@gmail.com>

The DNS action tests always passed a context inspector that found nothing, so none checked that a context detectDockerHost selects reaches the Docker commands. Add a case where the CLI default answers through the colima context and every Docker command runs against its socket. Without the context selection, it is the only test that fails.

Outcome
On macOS with Colima and
DOCKER_HOSTunset,nemoclaw onboardstarts the OpenShell gateway instead of failing withSocket not found: /var/run/docker.sock.Reason
Colima exposes Docker through a persisted
colimacontext and does not create/var/run/docker.sock. The gateway reads onlyDOCKER_HOST. Since #8823,detectDockerHostkeeps a reachable CLI default without settingDOCKER_HOST, which undid the fix for #3503.Related issues
Fixes #12367
Changes
defaultcurrent context when the Docker CLI default answers through it, as an explicitDOCKER_CONTEXTis selected ([Ubuntu 24.04][CLI&UX] host probe ignores DOCKER_CONTEXT and calls a machine ready that onboard refuses #11719)./var/run/docker.sockalready resolves to that socket, as with Docker Desktop.docs/reference/system-readiness.mdx.DOCKER_HOSTin the sandbox prebuild environment test, which otherwise inherits the socket thatrunner.tsnow exports on a Colima host.Verification

Review notes
