The litellm/litellm base image uses uv to manage a virtualenv at /app/.venv, which does not include pip. Running ensurepip first bootstraps pip inside the venv so we can install numpy, scikit-learn and other extra dependencies.

# ---------------------------------------------------------------
|
|
# Docker image for the Tool Router (based on the official LiteLLM image)
|
|
# ---------------------------------------------------------------
|
|
# Why use the official base?
|
|
# - It already contains the core LiteLLM binaries and entrypoint
|
|
# - Smaller image size (no extra OS packages we do not need)
|
|
# - Keeps the same security update cadence as the official image
|
|
#
|
|
# What we add:
|
|
# - Our Tool Router source code (tool_router_logger.py, config.yaml, etc.)
|
|
# - Extra Python dependencies required for the Jaccard/Embedding logic
|
|
# - numpy
|
|
# - scikit-learn
|
|
# - A tiny wrapper entrypoint that runs litellm --config /app/config.yaml
|
|
# ---------------------------------------------------------------
|
|
|
|
# 1. Use the official LiteLLM image (based on Alpine Linux)
|
|
FROM litellm/litellm:latest
|
|
|
|
# 2. Set environment variables that control the router
|
|
ENV \
|
|
PORT=4000 \
|
|
TOOL_ROUTER_SIMILARITY_MODE=jaccard \
|
|
TOOL_ROUTER_TOP_K=3 \
|
|
TOOL_ROUTER_MIN_SIMILARITY=0.15 \
|
|
TOOL_ROUTER_ALWAYS_INCLUDE=get_time,help,list_tools \
|
|
TOOL_ROUTER_EMBEDDING_MODEL=text-embedding-3-small
|
|
|
|
# 3. Create a non-root user (Alpine uses adduser, not useradd)
|
|
RUN adduser -D -u 1000 litellm && \
|
|
mkdir -p /app && \
|
|
chown -R litellm:litellm /app
|
|
|
|
# 4. Switch to that user for the rest of the steps
|
|
USER litellm
|
|
WORKDIR /app
|
|
|
|
# 5. Copy only the files that belong to the Tool Router
|
|
COPY --chown=litellm:litellm \
|
|
tool_router_logger.py \
|
|
config.yaml \
|
|
test_tool_router.py \
|
|
requirements.txt \
|
|
./
|
|
|
|
# 6. Install the extra Python deps that the router needs:
|
|
# - numpy (for cosine similarity)
|
|
# - scikit-learn (for the Jaccard fallback)
|
|
RUN python3 -m ensurepip --upgrade && \
|
|
python3 -m pip install --no-cache-dir -r requirements.txt
|
|
|
|
# 7. Expose the port used by LiteLLM
|
|
EXPOSE 4000
|
|
|
|
# 8. Healthcheck - LiteLLM returns a JSON health endpoint
|
|
HEALTHCHECK --interval=30s --timeout=5s --start-period=20s --retries=3 \
|
|
CMD curl -fsS "http://127.0.0.1:${PORT}/health" || exit 1
|
|
|
|
# 9. Default command - run the proxy with our config file
|
|
CMD ["sh", "-c", "litellm --config /app/config.yaml --port ${PORT} --host 0.0.0.0"] |
