# 사용자 생성 (UID 1000은 일반적인 비-root 사용자 ID)
RUN adduser --uid 1000 user

# !!! IMPORTANT: Change ownership of cache directories as root BEFORE switching user !!!
RUN chown -R user:user /tmp/huggingface_cache /tmp/huggingface_home /tmp/matplotlib_cache

# Switch to the non-root user for subsequent commands and application runtime
USER user

# Copy application code after switching user if you want it owned by 'user'
# Or copy it before and then chown it. This approach is usually cleaner.
# $HOME will now resolve to /home/user inside the container
COPY --chown=user . /home/user/app
