带子域的反向代理nginx码头容器

Question

我有一个带有多个服务连接到同一个网络的docker-compose.yml文件。这些服务包括nginx公开端口80、运行在0.0.0.0:8000上的web应用程序(App1)、运行在0.0.0.0:7000上的第二个web应用程序(App2)、在0.0.0.0:5000上运行的另一个web应用程序(App3)等等。

当转到0.0.0.0:8000或0.0.0:5000时，我可以从浏览器访问所有应用程序。

我想从浏览器中访问第一个带有"http://localhost“的应用程序，也就是第一个作为根的web应用程序。则其他域将是子域，例如，对于app2是从以下内容访问的："http://localhost/app2“

我已经尝试过的

我为每个web应用程序创建了一个服务器块，如下所示

 >> cat app1.conf
upstream app1 {
        server app1:8000;
}
server {
        # this server listens on port 80
        listen 80 ;
        
        server_name app1;

        # the location / means that when we visit the root url (localhost:80/), we use this configuration
        location / {
                
           proxy_pass http://app1;
        }
       
        
}

对于其中一个子域，我有：

upstream app2 {
        server app2:8000;
}
server {
        # this server listens on port 80
        listen 80 ;
        
        server_name app2;

        # the location / means that when we visit the root url (localhost:80/), we use this configuration
        location /app2 {
                
           proxy_pass http://app2;
        }      
}

这是我的docker-compose.yml文件：

version: "3.8"
 services:
  app1:
    image: app1 image
    container_name: app1
    networks:
      - local-network
    ports:
      - "8000:80"
    restart: unless-stopped
    
  app2:
    image: app2 image
    container_name: app2
    networks:
      - local-network
    ports:
      - "7000:80"
    restart: unless-stopped
   
  app3:
    image: app3 image
    container_name: app3
    networks:
      - local-network
    ports:
      - "5000:80"
    restart: unless-stopped
   
  nginx:
    image: nginx:latest
    container_name: nginx
    networks:
      - local-network
    command: nginx -g "daemon off;"
    volumes:
        - ./nginx/sites-available/app1.conf:/etc/nginx/conf.d/sites-available/app1.conf
        - ./nginx/sites-available/app2.conf:/etc/nginx/conf.d/sites-available/app2.conf
        - ./nginx/sites-available/app3.conf:/etc/nginx/conf.d/sites-available/app3.conf
        - ./nginx/nginx.conf:/etc/nginx/nginx.conf
    ports:
      - "80:80"
    restart: unless-stopped
    depends_on:
      - app1
      - app2
      - app3
 networks:
   local-network

在我的nginx.conf i中，包括启用站点和手动创建挂载站点的符号链接在内的nginx容器中可用的配置文件。

在浏览器上，"http://localhost/“工作正常，但是"http://localhost/app1”或app2或app3重定向到http://localhost/时，停靠程序日志中没有错误。

我可能做错什么了？

下面是一个快速示例，nginx conf文件和docker-come.yml：

~/Projects/docker/echo-test $ tree

.
├── docker-compose.yml
└── nginx
    └── app.conf

1 directory, 2 files

~/Projects/docker/echo-test $ cat nginx/app.conf

upstream app1 {
        server echoer1:7777;
}
upstream app2 {
        server echoer2:8888;
}
upstream app3 {
        server echoer3:9999;
}

server {
        listen 80;
        server_name localhost;

        location / {
                proxy_pass http://app1;
        }
        location /app2 {
                proxy_pass http://app2;
        }
        location /app3 {
                proxy_pass http://app3;
        }
}

~/Projects/docker/echo-test $ cat docker-compose.yml

version: "3.8"
services:
  echoer1:
    hostname: echoer1
    image: mendhak/http-https-echo
    environment:
      - HTTP_PORT=7777

  echoer2:
    hostname: echoer2
    image: mendhak/http-https-echo
    environment:

  echoer3:
    hostname: echoer3
    image: mendhak/http-https-echo
    environment:
      - HTTP_PORT=9999

  nginx:
    image: nginx
    command: nginx -g "daemon off;"
    volumes:
        - ./nginx/app.conf:/etc/nginx/conf.d/app.conf
    ports:
      - "80:80"
