Run 'docker container COMMAND --help' for more information on a command.

 

현재 컨테이너에는 아무 것도 없다.

C:\Users\samsung>docker container ls
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

C:\Users\samsung>docker image ls
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

 

실습을 하기 위해서 아래와 같은 코드를 입력해준다.

C:\Users\samsung>docker container run httpd

 

다운로드가 실행되고 나서 새로운 CMD에 docker dontainer ls를 입력하면 다음과 같이 나온다.

C:\Users\samsung>docker container ls
CONTAINER ID   IMAGE     COMMAND              CREATED          STATUS          PORTS     NAMES
681d406d28e5   httpd     "httpd-foreground"   32 seconds ago   Up 29 seconds   80/tcp    clever_turing

 

컨테이너를 종료 시키기 위해서는 docker container stop <이름> 이 필요하다.

docker container stop clever_turing

 

도커 컨테이너를 실행시키기 위해서 run을 사용했다. 

docker container run --name clever_turing -d -p 7605:80 httpd

 

7605 포트를 사용했기에 localhost:7605를 검색하면 아래 그림처럼 실행된다.
