Support for Alpine images

[Angelin01]

Alpine images are extremely common due to their small size.

For example, Python's 3.7.15-alpine3.17 image is 17.35MiB compressed while the 3.7.15-slim Ubuntu based one is 44.89MiB

As a side note, a Dockerfile as simple as this seems to work:

FROM python:3.10.8-alpine3.17 as build

ENV PYTHONDONTWRITEBYTECODE=1 \
    PYTHONUNBUFFERED=1 \
    PYTHONFAULTHANDLER=1 \
    POETRY_VERSION=1.2.2 \
    POETRY_VIRTUALENVS_IN_PROJECT=true \
    POETRY_NO_INTERACTION=1 \
    POETRY_HOME=/usr/bin/poetry \
    PATH=/usr/bin/poetry/bin:$PATH

RUN wget -O- https://install.python-poetry.org | python

ENTRYPOINT ["poetry"]

Thanks for the issue, Angelo!

I did not added Alpine suppprt because Python's performance are worse in them (some source).

But I see no problem on adding it to the image! I am a little busy until the end of the year, so I do not know when I can implement this feature. But if you want to do it yourself, it would be awesome!

Unfortunately I still have not written a contribution guide lines for the project, but the idea seems to be

• add Dockerfile-alpine.template file to the templates folder (very similar to the Dockerfile of your example).
• add -alpine to config.py
• assure the quality of code, from the project's CI (you can use Poetry, with poetry install && poetry shell, or pure pip, with pip install -r requirements/dev.txt && pip install -e ., to install the quality tools and run them locally).

Any question, you can ask me!
