我一直在使用 Docker 和 pipenv 進行資料科學部署設定，現在我想更改為 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"
這是基于我在 StackOverflow 上找到的其他 Dockerfile。我遇到了以下問題：
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
所以這看起來像沒有使用Poetry，安裝了Jupyter，因此找不到它。我怎樣才能解決這個問題？

這不是詩歌的問題，而是因為您嘗試安裝apt-get在 alpine 映像中使用的軟體包（不包括apt-get）。您還多次安裝某些軟體包，因為您首先使用 apk，然后使用 apt-get。你也不需要安裝 python，因為你使用 python 影像作為基礎。
我還建議只使用詩歌進行安裝，而不是轉儲到 requirements.txt 并使用官方安裝程式安裝詩歌。由于不支持python 3.8，您還必須使用python。

您的 Dockerfile 可能看起來像這樣：
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"]

根據 Asgeer 的回答，我設法修復了 Dockerfile。然而，事實證明使用 Alpine 是不可能的，最終的解決方案是：
FROM jupyter/scipy-notebook:latest
ENV POETRY_VIRTUALENVS_CREATE=false \
POETRY_VERSION=1.1.11
USER root
RUN apt-get update \
&& apt-get --yes install apt-utils \
&& apt-get --yes install curl
RUN curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -
ENV PATH "/home/jovyan/.local/bin:$PATH"
# install dependencies
COPY pyproject.toml poetry.lock ./
RUN poetry install --no-interaction --no-ansi
COPY . .
CMD ["jupyter", "notebook", "--port=8888", "--no-browser", "--ip=0.0.0.0", "--allow-root"]
