Docker Image Build

책에서 사용하는 docker의 base 이미지인 3.8.0-alpine으로 빌드 시 라이브러리 관련 빌드에러가 발생합니다. 아래의 reference 링크를 참고해서 python:3.8-slim-buster로 수정하고 RUN apk 부분을 삭제하면 정상적으로 빌드됩니다.

 

Docker Compose Up

docker image 생성을 위해 빌드 후 docker-compose up 수행 시 에러가 발생합니다. window기반으로 pip install 및 동작시에는 fromshare 부분이 문제가 발생하지 않지만 docker의 linux 이미지를 기반으로 빌드 시 아래와 같이 에러가 발생합니다.

django_blog-web-1  | ImportError: cannot import name 'fromshare' from 'socket' (/usr/local/lib/python3.8/socket.py)

 

stackover flow에 따르면 socket 라이브러리에서 사용하는 fromshare는 window에서만 사용하기 때문에 리눅스에서 빌드시 import를 못하는 것으로 보입니다. 코드 상에서 import fromshare부분을 제거한 후 다시 빌드하면 docker-compose up시 실행됩니다.
