Diary - Dockerfile Korean Locale Setup

During the Docker image build process, errors related to Korean locale settings (UTF-8) occur frequently. When that happens, putting the lines below into the Dockerfile resolved it nicely.

RUN pip install -r requirements_inference.txt
RUN apt-get update && apt-get install -y locales git
RUN localedef -f UTF-8 -i ko_KR ko_KR.UTF-8
ENV LC_ALL ko_KR.UTF-8
ENV PYTHONIOENCODING=utf-8

Or

ENV LANG C.UTF-8
ENV LC_ALL C.UTF-8
