Using Docker with Python Poetry?

I’ve been using Docker with pipenv for my data science deployment setup and now I want to change to Poetry. My Dockerfile is:

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"]

My 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"

This is based on other Dockerfiles that I found on StackOverflow. I run into the following problem:

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

So this looks like the Poetry is not used, where Jupyter is installed, and therefore it cannot be found. How can I fix this?

Answer

Based on Asgeer’s answer I managed to fix the Dockerfile. However, using Alpine turned out to be pretty impossible and the final solution is:

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"]
