# syntax=docker/dockerfile:1.6
#
# Multi-stage Swing Music image.
#
# Stage 1 (builder) compiles the premium Python modules with Nuitka and
# builds a wheel. Stage 2 (runtime) is a slim image that only contains
# the runtime deps (ffmpeg, libev) and the installed wheel. The .py
# source for premium modules never reaches the runtime stage — only the
# compiled .so extension modules do.

ARG PYTHON_VERSION=3.11

# The release workflow passes --build-arg app_version=<tag>. Export it as
# SETUPTOOLS_SCM_PRETEND_VERSION so the wheel's metadata carries the real
# version; without this, setuptools-scm can't see a git tag in the Docker
# build context and bakes "0.0.0" into METADATA, making Metadata.version
# return "0.0.0" at runtime.
