修改nginx.conf以支持n个wildfly实例

Question

我正在使用Jenkins和Docker实现docker解决方案。

在运行时，将决定在单独的docker容器中启动多少个wildfly实例。所有这些实例都使用Nginx进行负载平衡。

目前我的nginx.conf支持3个容器。我想在app-service列表下添加n个机器。有没有办法在nginx中提供这个？这是我的nginx.conf

worker_processes 4;
events { worker_connections 1024; }
http {
    upstream app-service {

          least_conn;
          server appA:8080;
          server appB:8080;
          server appC:8080 
    }

    server {
          listen 80;
          listen 443 default ssl;

          server_name appserver.domain.com;

        # Add Certificate
          #added my certs herey

          # optimization SSL code
          # ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;                                   
      location / {
            proxy_pass http://app-service;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
          }
    }

}

I can modify app-server list after starting all the instances but I am looking for a clean solution.

目前我只创建了一台服务器＆＃39;在nginx.conf文件和QA或Production中，我将能够分离端口80和443
