我想使用docker来包装nginx，fastapi和2个streamlit应用程序。所有3个应用程序(fastapi，2streamlight应用程序)都不能相互交互。Nginx应该可以作为这3个应用的反向代理。对于fastapi来说，它是有效的。我可以向http://ip:80/twxservices发送rest-api请求。"twxservices“作为端点添加到app.py文件中，而不是添加到nginxconfig中。

无法通过此http://ip:80/stream1和http://ip:80/stream2访问streamlit应用程序我收到错误: 404: not found

提前感谢您的帮助。在下面找到文件结构和配置文件。这是文件结构和反向代理的工作方式：

docker-compose文件：

services:
  web:
    build:
      context: ./nginxfolder
      dockerfile: Dockerfile
    container_name: web
   
    ports:
      - 80:80
    networks:
      - my-network
    depends_on:
      - app

  app:
    build:
      context: ./twxservicesfolder
      dockerfile: Dockerfile
    container_name: app
 
    networks:
      - my-network
      
  spectrum:
    build:
      context: ./spectrumfolder
      dockerfile: Dockerfile
    container_name: spectrum

    networks:
      - my-network
      
  dgraph:
    build:
      context: ./dgraphfolder
      dockerfile: Dockerfile
    container_name: dgraph

    networks:
      - my-network
       
networks:
  my-network:
    driver: bridge

nginx配置(default.conf)：

upstream fastapi-backend {
    server app:8000;
}



    server {
        listen 80;
     

        location /  {
            proxy_pass http://fastapi-backend;
            
            proxy_set_header Host $http_host;

            proxy_set_header X-Forwarded-Proto $scheme;
            
       
            proxy_redirect off;
            proxy_buffering off;
            client_body_buffer_size 100M;
            client_max_body_size 100M;
        }
        
        location /stream1 {
            proxy_pass http://spectrum:8501/stream1;
        }
        location ^~ /stream1/static {

        }
        location ^~ /stream1/vendor {

            proxy_read_timeout 86400;
        }
        
        location /stream2 {
            proxy_pass http://dgraph:8503/stream2;
        }
        location ^~ /stream2/static {
            proxy_pass http://dgraph:8503/stream2/static/;
        }
        location ^~ /stream2/healthz {
            proxy_pass http://dgraph:8503/stream2/healthz;
        }
        location ^~ /stream2/vendor {
            proxy_pass http://dgraph:8503/stream2/vendor;
        }
        location /stream2/dgraph {
            proxy_pass http://dgraph:8503/stream2/dgraph;
            proxy_http_version 1.1;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

我用这些nginx配置让它工作

    location /spectrum {
            proxy_pass http://spectrum1:8501/spectrum;
            proxy_http_version 1.1;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_read_timeout 86400;
        }

streamlit应用程序的Dockerfile配置如下：

FROM python:3.8
COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt

EXPOSE 8501
COPY app1.py /var/dashboard/app1.py
CMD streamlit run /var/dashboard/app1.py --server.address="0.0.0.0" --server.port="8501" --server.baseUrlPath="spectrum" --server.enableCORS=false --server.enableXsrfProtection=false
