 RUN useradd -m -u 1000 user
 
 # 2. Set Environment Variables
-# KEY CONDA TRICK: Add the new environment's bin to PATH immediately.
-# This prevents the need for "conda activate" or "source activate" later.
+# PATH: Ensures we use the conda python/pip/solara
+# LD_LIBRARY_PATH (NEW): Helps faiss-gpu find CUDA libraries without "conda activate"

 # 3. Set Working Directory

-# 4. Create the Conda Environment
-# We install python 3.9 and wget (to handle downloads cleanly)
-# We do this as root to ensure it installs correctly in /opt/conda
+# 4. Create Conda Environment
 RUN conda create -n app_env python=3.9 wget -y
 
-# 5. Install Requirements
-# Since we updated PATH in step 2, this 'pip' runs inside our conda env.
+# 5. Install Conda Packages
+# Note: We use '-n app_env' to target the specific environment
+RUN conda install -n app_env -c pytorch -c nvidia -c conda-forge faiss-gpu=1.7.4 -y && \

+# 6. Install Pip Requirements

-# 6. Fix Directory Permissions
-# Give the user ownership of the app folder before switching users
+# 7. Fix Permissions
 RUN chown -R user:user /home/user/app
 
-# 7. Switch to "user"
+# 8. Switch to User
 USER user
 
-# 8. Download the files
-# We use wget (installed via conda) instead of ADD. 
-# Because we are "USER user", these files are automatically owned by user.
-# This removes the need for the complex "ADD -> Switch to Root -> Chown -> Switch Back" dance.
+# 9. Download Files (Using wget inside the user context)
 RUN wget https://huggingface.co/datasets/mikonvergence/MajorTOM-SigLIP-Index-Viewer-App/resolve/main/siglip_ivfpq.index -O siglip_ivfpq.index && \
     wget https://huggingface.co/datasets/mikonvergence/MajorTOM-SigLIP-Index-Viewer-App/resolve/main/siglip_ivfpq_metadata.parquet -O siglip_ivfpq_metadata.parquet
 
-# 9. Copy remaining files
-# We removed 'siglip*' from here so we don't accidentally overwrite the downloaded files with local versions.
+# 10. Copy Application Code
 COPY --chown=user *.py *.css ./
 COPY --chown=user helpers/* ./helpers/
 
+# 11. Entrypoint
+# This will execute /opt/conda/envs/app_env/bin/solara
