Docker Optimization and cleanup script (도커 최적화 하기 🐳)
이 과정은
docker prune명령으로도 쉽게 가능합니다. 아래 댓글을 확인해주세요!😁
예전에 도커 용량 관련 문제로 한번 고생한적이 있었습니다. 도커 자체가 많이 사용할수록 리소스를 엄청쓰는데(물론 VM에 비하면 뭐…) 정기적으로 청소해주면 위에 문제나 용량, 속도 면에서 좀 이득이 되는 부분들이 있습니다. 그래서.. 구글링좀 해서 도커 clean up script 정리해봤습니다. 종종 돌려주시는게 좋아요 :)
크게 이미지, 컨테이터, 네트워크 어댑터를 정리하는 내용입니다.
Clean script
아래 부분 확인하고 별 이상 없을거라 생각도시면 하는거 추천드려요(괜한 이미지 날라갈수도
# clean containers
docker rm $(docker ps -qa --no-trunc --filter "status=exited")
# clean images
docker rmi $(docker images | grep "none" | awk '/ / { print $3 }')
# clean networks
docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')
# one line(container + images)
docker rm $(docker ps -qa --no-trunc --filter "status=exited");docker rmi $(docker images | grep "none" | awk '/ / { print $3 }');
Clean Images
우선 images 지우는건 이미지 중에 none 인 항목들만 지웁니다. 이미지를 계속 commit 해서 쓰기 떄문에 none은 쓸데없이 자리 차지하는 경우가 많죠
docker images | grep "none"
docker rmi $(docker images | grep "none" | awk '/ / { print $3 }')
저도 한 4개 정도 지워졌네요.
docker rmi $(docker images | grep "none" | awk '/ / { print $3 }')

Clean Containers
containers는 현재 구동중이지 않은 리스트들도 도커가 가지고 있습니다. 결국은 다 리소스를 차지하는거기 때문에 안쓰는건 지워줍니다.
docker ps -a --filter "status=exited"
docker ps 명령 중 –fileter 옵션이 있는데, 이걸로 종료된 컨데이너들을 찾아줍니다. 그리고 삭제해주시면 됩니다.
docker rm $(docker ps -qa --no-trunc --filter "status=exited")
저의 경우는….
docker rm $(docker ps -qa --no-trunc --filter "status=exited")

Clean Networks adaptor
마지막으로 bridge 네트워크에 대한 삭제인데, 이건 사용하시는거 체크해보고 하는게 좋을듯해요. 안해도 뭐 무방하지만, docker network도 네트워크 인터페이스로 잡히기 떄문에 최적화를 위해선 지워주는게 좋습니닷.
docker network ls | grep "bridge"
docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')
