docker - 通过Docker中的nginx代理将flask-socket事件传递到uWSGI服务器的位置

Question

我正在尝试在Docker上使用uwsgi和nginx设置使用Socket-IO事件(基于Flask-SocketIO)。我不确定如何配置我的nginx文件以允许客户端和服务器之间的套接字连接。这是我当前的nginx配置:

server {
    listen 80;
    server_name _;

    location / {
        try_files $uri @app;
    }

    location @app {
        include /etc/nginx/uwsgi_params;
        uwsgi_pass myapp:8080;
    }

    location /socket.io {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        uwsgi_pass myapp:8080/socket.io;
    }
}

Docker撰写:

version: '3.5'
services:
  web_server:
    container_name: nginx
    external_links:
      - app
    build:
      context: .
      dockerfile: server/Dockerfile
    ports:
      - 80:80
    depends_on:
      - app
  app:
    container_name: myapp
  build:
      context: .
      dockerfile: application/Dockerfile
    expose:
      - 8080

先感谢您!

Flask-SocketIO文档显示了一个示例nginx配置。这里是Socket.IO位置块:

    location /socket.io {
        include proxy_params;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_pass http://127.0.0.1:5000/socket.io;
    }

整个配置为 here。

您正在使用uwsgi_pass，根据我的理解，它不支持代理WebSocket连接。如本示例所示，使用HTTP。
