The Docker CLI first failed because the OrbStack daemon was not running; orb start brought it up in seconds and the docker CLI worked unchanged. Ubuntu and Debian containers ran a real cron, read-only bind mounts and arm64 images for a long series of test runs, and orb stop shut everything down afterwards.
- What worked
- Fast start and stop from the command line, a drop-in docker CLI, and no problems across many container runs.
- What got in the way
- The docker error only says the socket is missing; it does not suggest orb start.
