title: Django - Docker python: can't open file 'manage.py': [Errno 2] No such file or directory
body: <p>I am using Docker first time in my life and with various tutorials I got to this stage here. All steps are finishing correctly, but after last step succeeds I receive this  error:</p>
  <pre><code>Successfully built 66717d9cdec1
  Successfully tagged movie_universe_app:latest
  Recreating movie_universe_app_1 ... done
  Attaching to movie_universe_app_1
  app_1  | python: can't open file 'manage.py': [Errno 2] No such file or directory
  movie_universe_app_1 exited with code 2
  </code></pre>
  <p>And I don't know how to fix it. Here are my files:</p>
  <p>Dockerfile:</p>
  <pre><code>FROM python:3.8-alpine
  
  ENV PATH=&quot;/scripts:${PATH}&quot;
  
  COPY ./requirements.txt /requirements.txt
  RUN apk add --update --no-cache --virtual .tmp gcc libc-dev linux-headers
  RUN pip install -r /requirements.txt
  RUN apk del .tmp
  
  RUN mkdir /movie_universe
  COPY ./movie_universe /movie_universe
  WORKDIR /movie_universe
  COPY ./scripts /scripts
  
  RUN chmod +x /scripts/*
  
  RUN mkdir -p /vol/web/media
  RUN mkdir -p /vol/web/
  
  RUN adduser -D user
  RUN chown -R user:user /vol
  RUN chmod -R 755 /vol/web
  USER user
  
  CMD [&quot;entrypoint.sh&quot;]
  </code></pre>
  <p>docker-compose.yml</p>
  <pre><code>version: &quot;3.7&quot;
  
  services:
    app:
      build:
        context: .
      ports:
        - &quot;8888:8888&quot;
      volumes:
        - ./movie_universe:/movie_universe
      command: sh -c &quot;python manage.py runserver 0.0.0.0:8888&quot;
      environment:
        - DEBUG=1
  </code></pre>
  <p>entrypoint.sh:</p>
  <pre><code>#!/bin/sh
  
  set -e
  
  python manage.py collectstatic --noinput
  
  uwsgi --socket :8888 --master --enable-threads --module app.wsgi
  </code></pre>
  <p>I tried to delete &quot;volumes:&quot; from docker-compose.yml but it is still not working.</p>
  <p>Can please someone help me? Thanks.</p>
