我的 Dockerfile 基于@lmiuelvargasf 的回答。 请参阅他的帖子以获得更详细的解释。 我唯一的重大变化如下：

• 我现在使用最新的官方安装程序install-poetry.py而不是官方文档中推荐的已弃用的get-poetry.py 。 我还在使用--version标志安装特定版本，但您也可以使用环境变量POETRY_VERSION 。 有关其官方文档的更多信息！

• 我使用的PATH是/root/.local/bin:$PATH而不是 OP 的 Dockerfile 中的${PATH}:/root/.poetry/bin

FROM python:3.10.4-slim-buster

ENV PYTHONDONTWRITEBYTECODE 1 \
    PYTHONUNBUFFERED 1

RUN apt-get update \
    && apt-get install curl -y \
    && curl -sSL https://install.python-poetry.org | python - --version 1.1.13

ENV PATH="/root/.local/bin:$PATH"

WORKDIR /usr/app

COPY pyproject.toml poetry.lock ./

RUN poetry config virtualenvs.create false \
    && poetry install --no-dev --no-interaction --no-ansi

COPY ./src ./

EXPOSE 5000

CMD [ "poetry", "run", "gunicorn", "-b", "0.0.0.0:5000", "test_poetry.app:create_app()" ]

Answer 8

这是一种不同的方法，它使 Poetry 保持完整，因此您仍然可以使用poetry add等。如果您使用 VS Code 开发容器，这很好。

简而言之，安装Poetry，让Poetry创建虚拟环境，然后每次启动新shell时通过修改.bashrc进入虚拟环境。

FROM ubuntu:20.04

RUN apt-get update && apt-get install -y python3 python3-pip curl

# Use Python 3 for `python`, `pip`
RUN    update-alternatives --install /usr/bin/python  python  /usr/bin/python3 1 \
    && update-alternatives --install /usr/bin/pip     pip     /usr/bin/pip3    1

# Install Poetry
RUN curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python3 -
ENV PATH "$PATH:/root/.local/bin/"

# Install Poetry packages (maybe remove the poetry.lock line if you don't want/have a lock file)
COPY pyproject.toml ./
COPY poetry.lock ./
RUN poetry install --no-interaction

# Provide a known path for the virtual environment by creating a symlink
RUN ln -s $(poetry env info --path) /var/my-venv

# Clean up project files. You can add them with a Docker mount later.
RUN rm pyproject.toml poetry.lock

# Hide virtual env prompt
ENV VIRTUAL_ENV_DISABLE_PROMPT 1

# Start virtual env when bash starts
RUN echo 'source /var/my-venv/bin/activate' >> ~/.bashrc

提醒您无需避免使用 virtualenv。 它不会影响性能，而且 Poetry 并不是真正设计为没有它们就可以工作。

有两个项目你可以看到如何正确地做，或者你可以使用这些项目来构建你自己的图像，因为它们只是基础图像：

使用 docker 多阶段构建和 python slim image，将诗歌锁导出到 requirements.txt，然后通过 pip 在 vi​​rtualenv 中安装。

它具有最小的尺寸，不需要在运行时图像中添加诗歌，固定所有内容的版本。

FROM python:3.9.7 as base
ENV PIP_DISABLE_PIP_VERSION_CHECK=1
WORKDIR /app

FROM base as poetry
RUN pip install poetry==1.1.12
COPY poetry.lock pyproject.toml /app/
RUN poetry export -o requirements.txt

FROM base as build
COPY --from=poetry /app/requirements.txt /tmp/requirements.txt
RUN python -m venv .venv && \
    .venv/bin/pip install 'wheel==0.36.2' && \
    .venv/bin/pip install -r /tmp/requirements.txt

FROM python:3.9.7-slim as runtime
ENV PIP_DISABLE_PIP_VERSION_CHECK=1
WORKDIR /app
ENV PATH=/app/.venv/bin:$PATH
COPY --from=build /app/.venv /app/.venv
COPY . /app

我的 python 应用程序的 Dockerfile 看起来像这样 -

FROM python:3.10-alpine
RUN apk update && apk upgrade
RUN pip install -U pip poetry==1.1.13
WORKDIR /app
COPY . .
RUN poetry export --without-hashes --format=requirements.txt > requirements.txt
RUN pip install -r requirements.txt
EXPOSE 8000
ENTRYPOINT [ "python" ]
CMD ["main.py"]
