Docker Image 삭제시 에러가 발생하는 경우가 있다. 

technote@TechNote:~/docker$ docker image ls
REPOSITORY      TAG       IMAGE ID       CREATED         SIZE
my-test-build   latest    22b5185b193b   2 minutes ago   885MB
python          3         2a93c239d591   6 days ago      885MB
hello-world     latest    bf756fb1ae65   13 months ago   13.3kB
technote@TechNote:~/docker$ docker rmi bf756fb1ae65
Error response from daemon: conflict: unable to delete bf756fb1ae65 (must be forced) - image is being used by stopped container 83afae48b404
technote@TechNote:~/docker$ 

 

이는 삭제하려는 Image 가 container 로 사용되고 있어서 발생하는 것이기 때문에 해당 container 를 먼저 제거하고 Image 또한 삭제하면 된다.

technote@TechNote:~/docker$ docker container ls -a
CONTAINER ID   IMAGE         COMMAND    CREATED       STATUS                   PORTS     NAMES
83afae48b404   hello-world   "/hello"   2 weeks ago   Exited (0) 2 weeks ago             nostalgic_hofstadter
technote@TechNote:~/docker$ docker container rm 83afae48b404
83afae48b404
technote@TechNote:~/docker$ docker container ls -a
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
technote@TechNote:~/docker$

해당 Container를 삭제하고 Image 를 삭제하면 아래와 같이 에러없이 삭제되는 것을 확인할 수 있다. 

technote@TechNote:~/docker$ docker image ls -a
