답변을 받지 못해서 다시 남겨요

docker -v 로 돌아가는 거 확인도 했는데 ...

docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/containers/create: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

See 'docker run --help'.

이런 에러가 뜹니다.
