# Dockerfile for SL-GPS on Hugging Face Spaces
# Python 3.10 - all dependencies have pre-built wheels for this version
# NO source compilation allowed - using --only-binary for ALL packages

FROM python:3.10.15-slim

# Set working directory
WORKDIR /app

# Copy application code FIRST (so requirements.txt is available)
COPY . /app

# Only upgrade pip (minimal overhead)
RUN pip install --upgrade pip setuptools wheel

# Install from HF_SPACE_requirements.txt with STRICT wheel-only mode
# This prevents ANY source compilation, even if someone adds >= constraints
# Added -v flag for verbose output to help debug build issues
