将 Docker 与 Python Poetry 结合使用？

Question

我一直在使用 Docker 和 pipelinev 进行数据科学部署设置，现在我想更改为 Poetry。我的 Dockerfile 是：

FROM python:3.8-alpine3.13

ENV POETRY_VIRTUALENVS_CREATE=false \
    POETRY_VERSION=1.1.11

RUN apk add --no-cache python3-dev gcc libc-dev musl-dev openblas gfortran build-base postgresql-libs postgresql-dev libffi-dev \
  && pip install poetry
COPY pyproject.toml poetry.lock ./
RUN poetry export -f requirements.txt --output requirements.txt && sed -i 's/^-e //' requirements.txt

USER root
RUN apt-get update && apt-get install -y --no-install-recommends python3-dev gcc libc-dev musl-dev openssh-client git libpq-dev \
  && apt-get clean -y


# install dependencies from requirements.txt
RUN pip install --no-cache-dir --user -r requirements.txt

COPY . .
CMD ["jupyter", "notebook", "--port=8888", "--no-browser", "--ip=0.0.0.0", "--allow-root"]

我的pyproject.toml：

[tool.poetry]
name = ""
version = "1.0.0"
description = ""
authors = [""]

[tool.poetry.dependencies]
python = "^3.8"

... # lots of libraries, omitted here

[tool.poetry.dev-dependencies]
black = "*"
ipykernel = "6.*"
ipython = "7.*"
isort = "5.*"
jupyter = "*"
pytest = "6.*"
pre-commit = "2.*"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

这是基于我在 StackOverflow 上找到的其他 Dockerfile。我遇到以下问题：

Step 7/10 : RUN apt-get update && apt-get install -y --no-install-recommends python3-dev gcc libc-dev musl-dev openssh-client git libpq-dev   && apt-get clean -y
 ---> Running in 447ffb83d555
/bin/sh: apt-get: not found
The command '/bin/sh -c apt-get update && apt-get install -y --no-install-recommends python3-dev gcc libc-dev musl-dev openssh-client git libpq-dev   && apt-get clean -y' returned a non-zero code: 127
Running containerdocker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "jupyter": executable file not found in $PATH: unknown.
ERRO[0000] error waiting for container: context canceled 
make: *** [Makefile:6: jupyter_notebook] Error 127

所以这看起来像是安装了 Jupyter 的地方没有使用 Poetry，因此找不到它。我怎样才能解决这个问题？

Answer 1

这不是诗歌的问题，而是因为您尝试安装apt-get在高山图像中使用的软件包（不包括apt-get）。您还多次安装某些软件包，因为您首先使用 apk，然后使用 apt-get。另外，您不需要安装 python，因为您使用 python 图像作为基础。

我还建议仅使用诗歌进行安装，而不是转储到requirements.txt并使用官方安装程序安装诗歌。由于不支持 python 3.8，因此您还必须升级 python。

您的 Dockerfile 可能如下所示：

FROM python:3.9-alpine3.13

ENV POETRY_VIRTUALENVS_CREATE=false \
    POETRY_VERSION=1.1.11 \
    YOUR_ENV=development

RUN apk add --no-cache python3-dev gcc libc-dev musl-dev openblas gfortran build-base postgresql-libs postgresql-dev libffi-dev curl

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


# install dependencies
COPY pyproject.toml poetry.lock ./
RUN poetry install $(test "$YOUR_ENV" == production && echo "--no-dev") --no-interaction --no-ansi

COPY . .
CMD ["jupyter", "notebook", "--port=8888", "--no-browser", "--ip=0.0.0.0", "--allow-root"]
