django - Docker-compose 与 Django、Redis、Gunicorn、Uvicorn、Nginx：我的 Nginx 工作正常吗？

Question

我正在尝试使用 docker-compose 来设置以下内容：
容器 1：gunicorn 服务 django WSGI + uvicorn 服务 django ASGI（用于 websockets）
容器 2：redis 服务器用于 websockets
容器 3：nginx 服务器来处理 HTTP/websocket 请求和分别将它们引导到 WSGI/ASGI

但是，在 docker-compose up 之后，我的 nginx 服务器似乎无法正常工作。
我可以运行应用程序堆栈，而 redis/django 之间的通信没有问题，但我看不到我的 ngnix 在任何地方工作。
我的问题是：
1）我怎么知道我的 nginx 服务器正在工作？（即请求不是直接发送到 gunicorn/uvicorn 而是通过 nginx）
2）这是正确的设置吗？

这是我的 docker-compose.yml：

version: '3.1'
services:
  web_app_server:
    restart: always
    build: .
    container_name: web_app_server
    ports:
      - "8007:8765"
      - "8000:8000"

  redis_server:
    restart: always
    image: redis
    ports:
      - "6379:6379"

  nginx:
    image: nginx:1.13
    ports:
      - 1337:80
    volumes:
      - ./config/nginx/conf.d:/etc/nginx/conf.d
    depends_on:  # <-- wait for djangoapp to be "ready" before starting this service
      - web_app_server

在 Dockerfile 的末尾，用于在 docker-compose 中构建 web_app_server，我有

CMD ./dockerfile_start.sh

其中 dockerfile_start.sh 包含：

killall gunicorn
killall uvicorn
./gunicorn_wsgi.sh &
P1=$!
./uvicorn_asgi.sh &
P2=$!
wait $P1 $P2

使用 gunicorn_wsgi.sh：

gunicorn locallibrary.wsgi:application --bind 0.0.0.0:8765

和 uvicorn_asgi.sh

uvicorn locallibrary.asgi:application --reload --host 0.0.0.0 --port 8000

我的 nginx 配置文件 ./config/nginx/conf.d:/etc/nginx/conf.d:

upstream django_app {
    server web_app_server:8765;
}

upstream socker_server {
    server web_app_server:8000;
}

server {
    listen 80;

    location = /favicon.ico { access_log off; log_not_found off; }

    location /static/ {
            root /home/nlp_app/NLP_Toolkit_App/src/Django/locallibrary;
    }

    location / {
            include proxy_params;
            proxy_pass http://django_app;
    }

    location /2/ {
        proxy_pass http://socker_server;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_redirect off;
    }
}

这是 docker-compose up 后的打印输出：
