Question

我正在尝试使用network_mode：docker-compose中的host运行Nginx和PHP-FPM容器，当将network_mode定义为“ bridge”时，它可以正常工作，但是当将network_mode定义为“ host”时，我会收到：

nginx：在/etc/nginx/conf.d/ui.conf:10的上游“ ui”中找不到[emerg]主机

将network_mode设置为网桥时，一切正常，不幸的是，我需要将其设置为主机，因为我需要访问主机网络才能访问ueye摄像机。

这是我的docker-compose文件

version: '3'

services:
 nginx:
    image: nginx:alpine
    container_name: nginx
    tty: true
    ports:
      - "80:80"
      - "443:443"
      - "8000:8000"
    volumes:
      - ./../../ui/:/var/www/
      - ./nginx/:/etc/nginx/conf.d/
    network_mode: host

    depends_on:
      - ui
    restart: always
 ui:
    build:
      context: ./../../ui
      dockerfile: Dockerfile
    volumes:
      - ./../../ui/:/var/www/
    container_name: ui
    tty: true
    environment:
      SERVICE_NAME: ui
    working_dir: /var/www
    network_mode: host
    ports:
      - "9000:9000"

nginx conf文件

server {
    listen 80;
    index index.php index.html;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/public;
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass ui:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
    location / {
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
    }
}

Answer 1

在使用主机网络模式时，您的容器将Docker主机视为localhost而不是容器本身，因为它正在使用主机网络。尝试在您的nginx conf中将ui替换为localhost-

    fastcgi_pass localhost:9000;

在Docker的上游找不到Docker + Nginx主机
