Ubuntu – Pip instalation for Python 3.11 in docker

I have Dockerfile to build image for Django project that uses Python 3.11 and runs in poetry environment (see content below). Problem is when I try to donwload get-pip.py file and run it using Python, it says no such file or directory but it should be in the same directory where Dockerfile is. I don’t know, but why isn’t it there?

P.S. I use docker desktop with WSL 2 (Ubuntu 20.04) and Dockerfile is in project directory (where poetry.lock and pyproject.toml files are), /website is directory where django project is.

# Download image of Ubuntu 20.04
FROM ubuntu:20.04

# To prevent interactive dialogs
ENV TZ=Europe 
    DEBIAN_FRONTEND=noninteractive

# Update and install necessary packages
RUN apt-get update 
# Install necessary packages to allow compilation of source code
    && apt-get install -y --no-install-recommends 
    tzdata 
    build-essential 
    checkinstall 
    libreadline-gplv2-dev 
    libncursesw5-dev 
    libssl-dev 
    libsqlite3-dev 
    tk-dev 
    libgdbm-dev 
    libc6-dev 
    libbz2-dev 
    software-properties-common 
# Install python 3.11
    && apt-get update 
    && add-apt-repository ppa:deadsnakes/ppa 
    && apt-get install -y --no-install-recommends 
    python3.11

# Install pip for Python 3.11
RUN curl -sS -O https://bootstrap.pypa.io/get-pip.py | python3.11
# THERE'S AN ERROR
RUN python3.11 get-pip.py

# Install poetry
ENV POETRY_VERSION 1.4.2
RUN python3.11 -m pip3.11 install "poetry==$POETRY_VERSION"

# Install dependencies
RUN poetry install

# Run poetry env
ENTRYPOINT ["poetry", "shell"]

# Go to website folder
WORKDIR /website

# Run Django server
CMD ["python3.11", "manage.py", "runserver"]

    You are using pipe (|) to forward it to python, so the file doesnt end up in the directory but as stdin for python.311

    You have two options

    • download it via curl without piping it further

    • pipe it into python as you do now, but then you dont have to execute it explicitly (RUN python3.11 get-pip.py) because that’s what you did on previous line via piping

    If you want to pass curl output directly to python. don’t use -O args.

    -O, –remote-name: Write output to a local file named like the remote file we get.

    Instead of these lines.

    # Install pip for Python 3.11
RUN curl -sS -O https://bootstrap.pypa.io/get-pip.py | python3.11
# THERE'S AN ERROR
RUN python3.11 get-pip.py

    You can just write

    # Install pip for Python 3.11
RUN curl -sS https://bootstrap.pypa.io/get-pip.py | python3.11
