Poetry fails to install in Docker

Question

I've got alpine:edge as base image and want to use poetry in it. I'm trying to install it like that:

RUN curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
RUN source $HOME/.poetry/env

Script works without errors, but when I try to actually use it, bash says it is not installed:

Step 16/18 : RUN poetry install --no-dev
 ---> Running in 38ce454369cb
/bin/sh: poetry: not found

What can cause this issue?

UPD: Looks like there is something wrong with env file:

I've tried manually adding the binary to the path, but running

RUN export PATH=$PATH:/root/.poetry/bin

Seems to have no effect. When I shell into the container, path appears not to be changed.

Answer 1

The best solution I've came with is manually setting the env, since the binary itself installs fine

RUN curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
ENV PATH = "${PATH}:/root/.poetry/bin"
