# 3. Install Dependencies (As Root)
COPY --chown=user ./requirements.txt requirements.txt
RUN pip install --no-cache-dir --upgrade pip && \
pip install --no-cache-dir -r requirements.txt --extra-index-url https://download.pytorch.org/whl/cpu
# 4. PREPARE CACHE (Critical Fix)
# We create the directory and give 'user' ownership BEFORE switching users.
# This prevents "Permission Denied" errors at runtime.
RUN mkdir -p $HF_HOME && chown -R user:user $HF_HOME
# 5. SWITCH TO USER
# We switch users NOW so that the model download is owned by 'user', not 'root'.
USER user
# 6. DOWNLOAD MODEL (Memory Safe Fix)
# We use 'snapshot_download' instead of 'SentenceTransformer()'.
# This downloads the files to disk WITHOUT loading them into RAM (avoids OOM crashes).
RUN python -c "from huggingface_hub import snapshot_download; snapshot_download('sentence-transformers/all-mpnet-base-v2')"
# 7. Copy Code
# Since we are already 'user', we use --chown just to be safe.
COPY --chown=user . .
