# Containerfile.slim — SPEAR Climate Chatbot (without ingestion pipeline)
#
# Lightweight variant (~4-5 GB) that runs:
#   - RAG Service (port 8002) — query/retrieval only, no /ingest endpoint
#   - MCP Server (port 8000)
#   - Streamlit Chatbot (port 8501)
#
# For document ingestion (Nougat OCR + embedding), use the full Containerfile
# or run the ingestion pipeline on the host machine.
#
# API keys are NEVER baked into the image. Pass them at runtime:
#   podman run -e GEMINI_API_KEY=your_key -p 8501:8501 spear-earth-system-data-assistant:slim
#
# ChromaDB and merged markdown must be volume-mounted:
#   -v /path/to/chroma_db:/app/chroma_db
#   -v /path/to/nougat_merged_md:/app/nougat_merged_md
