SUMMARY

Minimal images that cannot run cannot be used in ansible-container. AFAIK ansible-container tries to do: docker exec -i <container> /bin/sh in this minimal container which will not work since nothing is in there (no /etc/passwd or /bin/sh).

STEPS TO REPRODUCE

atomic-ansible build -- -vvvv

EXPECTED RESULTS

ansible-container copying files into the container.

ACTUAL RESULTS

docker.errors.APIError: 500 Server Error: Internal Server Error ("linux spec user: unable to find user root: no matching entri
