# syntax=docker/dockerfile:1.6
#
# Dulus — multi-provider AI CLI runtime image.
#
# Build:
#   docker build -t kevrojo/dulus:latest .
#
# Run (interactive REPL):
#   docker run -it --rm \
#       -e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY \
#       -v dulus-memory:/root/.dulus \
#       kevrojo/dulus
#
# Run (daemon mode with webchat exposed on host :5050 — shifted off 5000 so
# a native Dulus install on the host can keep its default ports):
#   docker run -d --name dulus \
#       -e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY \
#       -v dulus-memory:/root/.dulus \
#       -p 5050:5000 -p 5152:5151 \
#       kevrojo/dulus dulus --daemon

#   docker pull ghcr.io/kevrojo/dulus:latest

# Build with --build-arg WITH_VOICE=1 if you plan to use [voice] (Whisper,
# sounddevice). It pulls libportaudio2 + ALSA dev headers so the sounddevice
# wheel can find PortAudio at runtime — without these you hit
# `OSError: PortAudio library not found` on first /voice call.

# (`dulus-gui` / customtkinter). Not needed for the REPL or the webchat
# HTTP server thanks to lazy GUI imports in 0.2.76+. Default off so the
# slim image stays slim.
