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

问题描述

我想使用 docker 来容器化 nginx、fastapi 和 2 个流式应用程序。所有 3 个应用程序（fastapi、2streamlit 应用程序）不相互交互。Nginx 应该作为这 3 个应用程序的反向代理。对于 fastapi，它正在工作。我可以将 rest-api 请求发送到 http://ip:80/twxservices 。“twxservices”作为端点被添加到 app.py 文件中，而不是 nginxconfig 中。

通过此 http://ip:80/stream1 和 http://ip:80/stream2 无法访问流光应用程序我收到错误：404：未找到

在此先感谢您的帮助。在文件结构和配置文件下方找到。这是文件结构以及反向代理应该如何工作：

nginx 配置（default.conf）：

upstream fastapi-backend {
    server app:8000;
}



    server {
        listen 80;
     

        location /  {

Dockerfile nginx 容器：

FROM nginx:latest

RUN rm /etc/nginx/conf.d/default.conf
COPY default.conf /etc/nginx/conf.d

Dockerfile streamlit app dgraph 容器：

FROM python:3.8

COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt

EXPOSE 8503
COPY app2.py /var/dashboard/app2.py
CMD streamlit run /var/dashboard/app2.py --server.address="0.0.0.0"  --server.port="8503"

Dockerfile streamlit 应用频谱容器：

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"

Dockerfile fastapi app twxservices 容器：

FROM python:3.8-slim-buster

COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt
COPY . .

ENV PYTHONUNBUFFERED 1

EXPOSE 8000
CMD ["uvicorn","app:app","--proxy-headers","--host","0.0.0.0","--forwarded-allow-ips","*"]

解决方案

我使它与这些 nginx 配置一起工作

    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;
        }

和流光应用程序的这个 Dockerfile 配置：

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
