debian docker 컨테이너 구동하고 들어가보기

2 docker run[ | ]

2.1 최신버전[ | ]

docker run -it --name mydebian debian bash

→ 이름을 mydebian이라고 지정하였다.

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

docker run -it --name mydebian debian:10 bash
docker run -it --name mydebian debian:buster bash

3 docker run & docker exec[ | ]

컨테이너를 detached 상태로 구동해두고, 이후에 exec로 들어가 보기

docker run -d --name mydebian debian sleep infinity
docker exec -it mydebian bash

→ -d 옵션을 붙여서 detached 모드로 구동한다.

→ 아무 명령어도 주지 않으면 컨테이너가 즉시 종료되므로 sleep infinity를 실행하였다.

3.1 실습[ | ]

docker run -d --name mydebian debian  sleep infinity
docker exec -it mydebian bash

$ docker run -d --name mydebian debian sleep infinity
