alpine docker 컨테이너 구동하고 들어가보기

2 docker run[ | ]

docker run -it --name myalpine alpine /bin/sh

→ 이름을 myalpine이라고 지정하였다.

→ 이름을 지정하는 이유는, 삭제하거나 할 때 식별이 용이하기 때문이다.

3 docker run & docker exec[ | ]

컨테이너를 detached 상태로 구동해두고, 이후에 exec로 들어가 보기

docker run -d --name myalpine alpine
docker exec -it myalpine  /bin/sh

3.1 실습[ | ]

docker run -d --name myalpine alpine
docker exec -it myalpine  /bin/sh

$ docker run -d --name myalpine alpine sleep infinity
