Как создать образ Docker для ссылки на библиотеку Python в Venv

Я пытаюсь докернизировать мое веб-приложение Django, которое работает в виртуальной среде. venv,

Это мой конфиг для моего Dockerfile:

FROM ppc64le/python:2.7

ENV PYTHONUNBUFFERED 1 
ENV DJANGO_SETTINGS_MODULE=agricultureProj.settings.deploy 
ENV UWSGI_VIRTUALENV=/venv 
UWSGI_WSGI_FILE=agricultureProj/wsgi.py 
UWSGI_HTTP=:8005 
UWSGI_MASTER=1 
UWSGI_WORKERS=2 
UWSGI_THREADS=8 
UWSGI_UID=1000 
UWSGI_GID=2000 
UWSGI_LAZY_APPS=1 
UWSGI_WSGI_ENV_BEHAVIOR=holy

RUN virtualenv venv 
RUN source /venv/bin/activate 
RUN mkdir /code 
WORKDIR /code   

ADD requirements.txt /code/ 
RUN pip install -r requirements.txt

ADD . /code/

EXPOSE 8005

COPY ./docker-entrypoint.sh / 
RUN chmod uog+rx ./docker-entrypoint.sh 
ENTRYPOINT ["sh","/docker-entrypoint.sh"]

CMD ["/venv/bin/activate", "--http-auto-chunked", "--http-keepalive"

Я хотел бы знать, как я должен определить свой Dockerfile, чтобы я мог напрямую ссылаться на существующую библиотеку Python и успешную сборку и компоновку, запустить для этого мой образ докера.

** Append:

Это ошибка, с которой я столкнулся после успешного создания образа докера.

Ошибка:

Не активируйте виртуальную среду, просто добавьте ее bin каталог к началу PATH переменная окружения. Обычно этого достаточно.

Вы также должны избегать запуска своего изображения как root, Даже в контейнере это не очень хорошая практика.

Вы можете использовать --system-site-packages, чтобы указать venv для использования системных библиотек в приоритете, что означает изменение этой строки, а затем указание pip, чтобы игнорировать установленные системы библиотеки

RUN virtualenv --system-site-packages venv 
RUN source /venv/bin/activate 
RUN mkdir /code WORKDIR /code
ADD requirements.txt /code/ 
RUN pip install --ignore-installed -r requirements.txt
