nginx和wordpress不同的docker-compose文件

我正在尝试使用一个nginx docker-compose文件连接多个docker-compose文件。

例如,此设置很有效(我在运行之前创建了网络):

(请耐心等待。我知道这个例子是多余的,因为我有两个nginx服务器)

#static_site/docker-compose.yml
version: '3'

services:
  web:
    image: nginx:stable-alpine
    container_name: app_web_static
    volumes:
      - "./nginx.conf:/etc/nginx/conf.d/default.conf"
      - "./web:/var/www/static_web"
    ports:
      - "8080:8080"
    networks:
      - test_network
#static_site/nginx.conf
server {
    listen 8080;

    location / {
       root /var/www/static_web;
       index  index.html index.htm;
    }
}
#nginx/docker-compose.yml
server {
    listen 80;
    server_name myapp.local;

    #Docker DNS
    resolver 127.0.0.11;

    location / {
        set $docker_host "app_web_static"; 
        proxy_pass http://$docker_host:8080;
    }
}

我运行容器,一切都按预期工作。我的网站是通过myapp.local代理的

BUT。当我将静态网站更改为如下的wordpress图像时:

#wordpress/docker-composer.yml
wordpress:
    image: wordpress
    container_name: app_web
    links:
      - db:mysql
    ports:
      - "8080:80"
    restart: always
    environment:
      WORDPRESS_DB_PASSWORD: example
    networks:
      - test_network
      - test_wordpress_db

  db:
    image: mysql:5.7
    container_name: test.web.db
    ports:
      - 3306:3306
    environment:
      MYSQL_ROOT_PASSWORD: example
    volumes:
      - ./mysql/data:/var/lib/mysql
    networks:
      - test_wordpress_db

我再次运行容器(在更新nginx .yml文件之后)。我收到请求记录在我的终端(nginx容器,这意味着请求处理),但作为一个错误: test.nginx | [error] 5#5: *6 connect() failed (111: Connection refused) while connecting to upstream, client: 172.23.0.1, server: myapp.local, request: "GET / HTTP/1.1", upstream: "http://172.23.0.2:8080/", host: "myapp.local"

当我从localhost:8080访问它时,wordpress应用程序正在运行。

此配置中的wordpress app有问题吗?它无法检测到我的主人或什么?我该如何解决这个问题?

1 个答案:

答案 0 :(得分:0)

我明白了。

似乎我必须使用内部端口为我的proxy_pass而不是外部端口。例如,对于wordpress docker-compose.yml文件,我必须像这样编写代理:

#nginx/docker-compose.yml
server {
    listen 80;
    server_name myapp.local;

    #Docker DNS
    resolver 127.0.0.11;

    location / {
        set $docker_host "app_web_static"; 
        proxy_pass http://$docker_host:80; # here. the internal wordpress port
    }
}
