docker - 将Nginx添加到我的Docker化Django应用程序中

Question

我已成功将gunicorn添加到我的Dockerized Django应用程序中。我在向混音中添加Nginx时遇到问题。 Nginx服务器几乎立即退出。任何帮助，将不胜感激。
这是我的docker-compose.yml

version: "3"

services:
  web:
      build: 
          context: .
          args:
            HTTP_PROXY: http://amec.zscaler.company.com:9480
            HTTPS_PROXY: http://amec.zscaler.company.com:9480
      image: django_web 
      container_name: django_web  
      expose: 
        - "8000"
  nginx:
      build: ./nginx
      ports:
        - 1337:80
      depends_on:
        - web

这是我的Dockerfile:

FROM python:3.6

ENV PYTHONUNBUFFERED 1
ENV PYTHONDONTWRITEBYTECODE 1

ARG HTTP_PROXY
ARG HTTPS_PROXY

COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt

RUN mkdir /code
WORKDIR /code
ADD . /code/
RUN useradd user
USER user

CMD ["gunicorn", "django_web.wsgi:application", "--bind", "0.0.0.0:8000"]

这是我的nginx / Dockerfile:

FROM python:3.6
COPY nginx.conf /etc/nginx/conf.d

这是nginx.conf:

upstream django_web{
    server web:8000;
}

server {
    listen 80;

    location / {
        proxy_pass http://django_web/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }
}

生成并运行所有命令的命令:

sudo docker-compose -f docker-compose.cambridge.yml up -d

下一条命令:

sudo docker ps -a
    
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
16f4651047ec        django_nginx       "python3"                20 seconds ago      Exited (0) 18 seconds ago                 django_nginx_1
03a460153a9c        django_web         "gunicorn Django.…"      21 seconds ago      Up 19 seconds               8000/tcp            django_web

当我运行 sudo docker exec -ti 16f4651047ec ping web时，我会得到积极的回应。
新构建后，我运行: sudo docker logs 16f4651047ec我得到:

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration 

/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/ 

/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh

在尝试浏览到 http://my-ip:1337/之后，我运行: sudo docker logs 16f4651047ec我得到与上述相同的内容，外加以下一行:

您正在构建Nginx图片FROM python:3.6
这是一个简单的nginx:alpine Dockerfile示例:

FROM nginx:alpine
COPY nginx.conf /etc/nginx/nginx.conf
