Dockerfile

# Hugging Face Spaces image. Extends the official SIE server image, adds
# Node 22 for the UI server, and runs both processes from one container.
#
# This Dockerfile is HF Spaces specific. Local Docker users should use
# compose.yml (which just runs the unmodified upstream SIE image with the
# Node UI on the host).
#
# We use a multi-stage build to grab Node binaries from the official
# node:22-bookworm-slim image. HF Spaces' build sandbox restricts apt-key
# tmp-file writes, so installing Node via apt fails. Copy approach avoids
# apt entirely.

# --- stage 1: pull Node binaries ---
FROM node:22-bookworm-slim AS node

# --- stage 2: final image ---
FROM ghcr.io/superlinked/sie-server:latest-cpu-transformers5
