docker 带有 django gunicorn nginx 的容器

Question

我正在尝试使用 gunicorn 和 nginx 将 django docker化为 docker 图像。来自 this tutorial

运行 docker-compose up --detach --build 一切构建成功。但是 gunicorn 没有启动。错误日志显示：

bash: /home/soccer/venv/bin/gunicorn: /Users/Umar/PycharmProjects/soccer/venv/bin/python: bad interpreter: No such file or directory

我该如何解决这个问题？

Dockerfile:

# pull official base image
FROM python:3.7

# accept arguments
ARG PIP_REQUIREMENTS=production.txt

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip setuptools

# create user for the Django project
RUN useradd -ms /bin/bash soccer


# set current user
USER soccer

# set work directory
WORKDIR /home/soccer

# create and activate virtual environment
RUN python3 -m venv venv

# copy and install pip requirements
COPY --chown=soccer ./requirements /home/soccer/requirements/
RUN pip3 install -r /home/soccer/requirements/${PIP_REQUIREMENTS}

# copy Django project files
COPY --chown=soccer . /home/soccer/

docker-compose.yml:

version: "3.8"

services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - ./config/nginx/conf.d:/etc/nginx/conf.d
      - static_volume:/home/soccer/static
      - media_volume:/home/soccer/media
    depends_on:
      - gunicorn

  gunicorn:
    build:
      context: .
      args:
        PIP_REQUIREMENTS: "${PIP_REQUIREMENTS}"
    command: bash -c "/home/soccer/venv/bin/gunicorn --workers 3 --bind 0.0.0.0:8000 soccer.wsgi:application"
    depends_on:
      - db
    volumes:
      - static_volume:/home/soccer/static
      - media_volume:/home/soccer/media
    expose:
      - "8000"
    environment:
      DJANGO_SETTINGS_MODULE: "${DJANGO_SETTINGS_MODULE}"
      DJANGO_SECRET_KEY: "${DJANGO_SECRET_KEY}"
      DATABASE_NAME: "${DATABASE_NAME}"
      DATABASE_USER: "${DATABASE_USER}"
      DATABASE_PASSWORD: "${DATABASE_PASSWORD}"

  db:
    image: postgres:latest
    restart: always
    environment:
      POSTGRES_DB: "${DATABASE_NAME}"
      POSTGRES_USER: "${DATABASE_USER}"
      POSTGRES_PASSWORD: "${DATABASE_PASSWORD}"
    ports:
      - 5432
    volumes:
      - postgres_data:/var/lib/postgresql/data/

volumes:
  postgres_data:
  static_volume:
  media_volume:

我发现了问题。我正在覆盖 venv。解决方案是将虚拟环境添加到 .dockerinfo 文件。
