docker 이미지 빌드 시 "RUN apt install ..." 명령어가 실패하는 이유

docker 이미지를 만들 때 apt-get udpate/upgrade도 해놓았는데요,

RUN apt-get update
RUN apt-get upgrade -y

이후 dockerfile의 내용에 sysstat을 설치하는 명령을 추가했더니,

RUN apt install sysstat -y

이렇게 오류가 발생합니다.

그런데, 위의 메시지를 확인해 보면 재미있는 점이 있습니다. 바로 ""RUN apt-get update/upgrade" 명령어도 다름 아닌 "CACHED" 처리되었다는 점입니다.

따라서 cache를 이용하지 않도록 만들어야 하는데요, 이를 위해 "--no-cache" 옵션을 (실패할 때마다 한 번씩만) 추가하면 됩니다.

이 현상 덕분에 지난번에 겪었던 그 글의 원인이 밝혀집니다. ^^;

Linux - apt와 apt-get의 차이
; https://www.sysnet.pe.kr/2/0/13075

그러니까, 그때 당시에 "RUN apt update/upgrade"는 CACHED 처리되었기 때문에 "apt install libpq-dev" 명령어가 실패했던 것입니다. 하지만, 명령어를 apt-get으로 바꾸면 CACHED가 아닌, 새롭게 이미지를 재구성했기 때문에 정상적으로 이미지 빌드가 되었던 것이고!
