Docker 실습 :: Image 삭제 방법

<Image 삭제>

컨테이너 활성화를 끄고, 컨테이너를 지우고 이미지를 지우는 과정

 

1. 컨테이너 비활성화

• 컨테이너 정지 상태여야 함

ubuntu@host1:~/Labs$ docker container stop $(docker container ps -a | grep Up)

>> Up되어 있는 컨테이너 모두 정지

 

<상태 확인>

ubuntu@host1:~/Labs$ docker container ps -a

2. 컨테이너 삭제

ubuntu@host1:~/Labs$ docker container ps --filter 'status=exited' -a -q
7a0d333a17f8
d8186f16e4f6
68858f6f8205

0b9369296812
f9bfb7797618
a6a1333808a4
95f202fb53fe
>> exited 되어 있는 컨테이너 목록 확인

ubuntu@host1:~/Labs$ docker container rm $(docker container ps --filter 'status=exited' -a -q)
7a0d333a17f8
d8186f16e4f6

<삭제 확인>

ubuntu@host1:~/Labs$ docker container ps -a
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
