Docker로 옮기고 싶었으므로 방금 엉망이되었습니다. VirtualBox Ubuntu 15.10 (Wily Werewolf) 설치에 Docker를 설치했으며 여기 에서 제안한 것처럼 기본 nginx Docker 이미지를 실행하려고 시도했습니다 .
$ docker run --name mynginx1 -P -d nginx
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
그래서 Docker가 실행 중인지 확인했습니다.
$ sudo service docker status

그런 다음 이미지를 다시 실행했지만 동일한 결과를 얻었습니다.
$ docker run --name mynginx1 -P -d nginx

나는 명령을 sudo'ing했지만 아무 소용이 없었다. 내가 여기서 뭘 잘못하고 있니?
