Question

在配置多个服务（其中Nginx是代理服务器）时，我有些困惑。

运行：

docker -v                      
Docker version 19.03.8, build afacb8b7f0

docker-compose -v                              
docker-compose version 1.23.2, build 1110ad01

我想从此测试开始，所有内容都在同一docker-compose.yml-file中：链接到jwilder/nginx

代理：nginx服务器（jwilder / nginx-代理：0.7.0，即nginx 1.17.6）
container1：httpd：2.4
container2：httpd：2.4

在开始之前更新/ etc / hosts

127.0.0.1 container1.com
127.0.0.1 container2.com

这是我的 docker-compose.yml文件（obs->版本3.7）

version: '3.7'

services:

  proxy:
    image: jwilder/nginx-proxy:0.7.0
    container_name: proxy-test
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - ./nginx-proxy.conf:/etc/nginx/conf.d/nginx-proxy.conf:ro

  container1:
    image: httpd:2.4
    container_name: container-1
    environment:
      - VIRTUAL_HOST:container1.com
    ports:
      - 8080:80

  container2:
    image: httpd:2.4
    container_name: container-2
    environment:
      - VIRTUAL_HOST:container2.com
    ports:
      - 8081:80

这是我的 nginx-proxy.conf ：

server {
    listen          80;
    server_name     container1.com;
    location / {
        proxy_pass http://localhost:8080;
    }
}

server {
  listen        80;
  server_name   container2.com;

  location / {
    proxy_pass  http://localhost:8081;
  }
}

此后，我运行

docker exec container-1 sed -i 's/It works!/Container 1/' /usr/local/apache2/htdocs/index.html AND

docker exec container-2 sed -i 's/It works!/Container 2/' /usr/local/apache2/htdocs/index.html

测试1：弯曲端口8080和8081

curl localhost:8080
response -> Container 1

curl localhost:8081 
response -> Container 2

测试2：卷曲到container1.com AND container2.com

curl container1.com
status 502
curl container2.com
status 502

我的conf中的设置是否错误？

故障排除1：

docker exec -it proxy-test bash
我可以看到nginx-proxy.conf位于目录（/etc/nginx/conf.d）
/etc/nginx/conf.d/default.conf也在那里

故障排除2：代理日志（Connection refused - while connecting to upstream）

proxy-test    | nginx.1    | 2020/04/03 10:52:08 [error] 61#61: *9 connect() failed (111: Connection refused) while connecting to upstream, client: 172.29.0.1, server: container1.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "container1.com"
proxy-test    | nginx.1    | 2020/04/03 10:52:08 [error] 61#61: *9 connect() failed (111: Connection refused) while connecting to upstream, client: 172.29.0.1, server: container1.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "container1.com"

Answer 1

找到2个解决方案。

（1）第一种是使用容器名称更新nginx-proxy.conf，而不是指向http://localhost:8080;和http://localhost:8081;：

新的配置文件

server {
    listen          80;
    server_name     container1.com;
    location / {
        proxy_pass http://container-1;
    }
}

server {
    listen        80;
    server_name   container2.com;

    location / {
      proxy_pass  http://container-2;
    }
}

（2）省略nginx-proxy.conf-file，docker-compose.yml可以正确映射内容。
