alpine.dockerfile

# Setup an Alpine test environment with Python 3.9, PyInstaller and its test dependencies.
#
# To build, boot into and invoke pytest inside this image run:
#
#   docker build -f alpine.dockerfile -t some-arbitrary-name .
#   docker run -it some-arbitrary-name
#   pytest
#
# Or if you prefer a one-liner:
#
#   docker run -it $(docker build -q -f alpine.dockerfile .) pytest
#
# This docker file should be used for testing only. The bootloaders it compiles internally are not suitable for PyPI.
#
# ---
# This dockerfile is 2-part. The first half builds and the second tests. The test half should only contain PyInstaller's
# runtime and test dependencies - no C compiler or dev packages. Once other packages start shipping musl compatible
# wheels, most or possibly all of the build half will be safely removable.
