# 1. Set up user
RUN useradd -m -u 1000 user

# 2. Set Environment Variables
# We need LD_LIBRARY_PATH for Faiss/MKL.
# We also set SOLARA_PROXY_CACHE_DIR to be safe.

# 3. Working Directory
WORKDIR /home/user/app

# 4. Create Conda Env
RUN conda create -n app_env python=3.9 wget -y

# 5. Install Faiss via Conda (Pinned MKL)
# This handles the "libmkl_intel_lp64.so.1" error
RUN conda install -n app_env -c pytorch -c nvidia -c conda-forge faiss-gpu=1.7.4 mkl=2021 blas=1.0=mkl -y && \

# 6. Install Pip Requirements
COPY requirements.txt .
# This runs as root and creates a root-owned /home/user/.cache
RUN pip install --no-cache-dir --upgrade pip && \
    pip install --no-cache-dir -r requirements.txt

# 7. Fix Permissions (THE FIX)
# We recursively chown the ENTIRE home directory.
# This fixes the root-owned .cache folder created by pip in step 6.
RUN chown -R user:user /home/user

# 8. Switch to User
USER user

# 9. Download Files
