nginx의 최신 버전 이미지로 컨테이너를 생성하라. 단, 컨테이너의 이름은 nginx이고 background 상태여야 한다. 또한 해당 컨테이너의 IP 주소를 통해 동작 여부를 확인하라.

  1. root@ubuntu:~# docker run --name nginx -d nginx:latest

    root@ubuntu:~# docker run --name nginx -d nginx:latest

    사실 docker pull image nginx로 먼저 땡겨오는 게 정석이다.

  2. root@ubuntu:~# docker ps -a

    root@ubuntu:~# docker ps -a

  3. root@ubuntu:~# docker inspect nginx

    ...
    

    또는 다음과 같이 확인한다.
