docker 中的 Nginx、fastapi 和 streamlit - 反向代理不适用于 streamlit

Question

i want to use docker to containerize nginx, fastapi and 2 streamlit apps. All 3 apps (fastapi, 2streamlit apps) do not interact with each other. Nginx should work as reverse-proxy for the 3 apps. For fastapi it is working. I can send rest-api requests to http://ip:80/twxservices . "twxservices" as endpoint is added in the app.py file and not in the nginxconfig.

The streamlit apps are not reachable through this http://ip:80/stream1 and http://ip:80/stream2 I get the error: 404: Not found

Thanks in advance for your help. Find below the filestructures and the config files. This is the filestructure and how the reverse-proxy should work:

docker-compose file:

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

nginx config (default.conf):

I made it work with these nginx config

    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;
        }

and this Dockerfile config for the streamlit app:

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
