# ChaosOps AI — Hugging Face Spaces Dockerfile
#
# Hugging Face Spaces convention:
# * Image must run as a non-root user (uid 1000).
# * App listens on port 7860 (Spaces routes external traffic to this port).
# * /home/user/app is the working directory the Space picks up automatically.
#
# Build pipeline is split so pip-install layer is cached independently of the
# app code — every code edit only re-uploads the small final COPY.

FROM python:3.11-slim

# System deps:
#   git   — pip needs this to install `chaosops` from the GitHub source.
#   curl  — handy for in-container HF Hub debug; small footprint.
