Python gunicorn не работает с Docker CMD

У меня есть django App, который также запускает некоторые шаблоны Javascript с помощью node. Я пытаюсь запустить Gunicorn в качестве CMD в Dockerfile.

Вот мой dockerfile:

FROM node:22.12.0-alpine3.21

RUN mkdir /app
COPY . /app

WORKDIR /app/tools
RUN npm install --loglevel verbose
RUN npm run build

WORKDIR /app
RUN ls -la

# Set environment variable for Python version
ENV PYTHON_VERSION 3.10.10

# Install dependencies and Python 3.10
RUN apk update
RUN apk update && apk add --no-cache \
    build-base \
    bash \
    libffi-dev \
    zlib-dev \
    bzip2-dev \
    ncurses-dev \
    openssl-dev \
    sqlite-dev \
    readline-dev \
    tk-dev \
    gdbm-dev \
    xz-dev \
    libnsl-dev \
    curl \
    dcron
RUN curl -O https://www.python.org/ftp/python/${PYTHON_VERSION}/Python-${PYTHON_VERSION}.tgz \
    && tar -xvf Python-${PYTHON_VERSION}.tgz \
    && cd Python-${PYTHON_VERSION} \
    && ./configure --enable-optimizations \
    && make -j$(nproc) \
    && make altinstall \
    && cd .. \
    && rm -rf Python-${PYTHON_VERSION} Python-${PYTHON_VERSION}.tgz \
    && python3.10 --version

RUN ln -sf /usr/local/bin/python3.10 /usr/bin/python3 \
    && ln -sf /usr/local/bin/pip3.10 /usr/bin/pip3

# Verify Python and pip installation
RUN python3 --version && pip3 --version
# Install pip and upgrade setuptools and wheel
RUN pip3 install --no-cache --upgrade pip setuptools wheel
RUN pip3 install -r requirements.txt

EXPOSE 8000

ENV PYTHONPATH=/app
WORKDIR /app
CMD ["python3", "-m", "gunicorn", "--bind", "0.0.0.0:8000", "wsgi.application"]

У меня есть wsgi.py на том же уровне manage.py.

Проблема заключается в следующем:

  • В Dockerfile, CMD ["python3","manage.py", "runserver", "0.0.0.0:8000"] РАБОТАЕТ ✅
  • docker run --rm -it -p 8000:8000 <image> python3 -m gunicorn --bind 0.0.0.0:8000 wsgi:application РАБОТАЕТ ✅
  • В Dockerfile, CMD ["gunicorn", "--bind", "0.0.0.0:8000", "wsgi.application"] НЕ РАБОТАЕТ ❌

Ошибка, которую я получаю:

ПОЧЕМУ? ЛЮБАЯ ПОМОЩЬ ПРИВЕТСТВУЕТСЯ!

In the Django dcumentation "How to use Django with Gunicorn", you can find this syntax for the command.

gunicorn myproject.wsgi

... It requires that your project be on the Python path; the simplest way to ensure that is to run this command from the same directory as your manage.py file.

I checked the Docker Compose setup I use for a project — it works for my ASGI application.

gunicorn myproject.asgi:application --bind 0.0.0.0:8000
