目前我有2个Docker容器：
我使用docker-composer分别启动两个容器Nginx正在侦听端口8080，并且应该将HTTP请求转发到正在侦听端口8081的应用程序。目前这不起作用，因为nginx不知道有关应用程序容器的任何信息。
86615a5b0f02 parzee/loadbalancer "/usr/local/bin/start" 3 minutes ago Up 3 minutes 127.0.0.1:8080->8080/tcp loadbalancer_loadbalancer_1 9adc8a04b356 parzee/application "/usr/local/bin/start" 6 minutes ago Up 5 minutes 127.0.0.1:8081->8081/tcp application_application_1 这是我的默认configuration
upstream application { ip_hash; server application_application_1:8081 fail_timeout=0; server application_application_2:8081 fail_timeout=0; keepalive 64; } server { listen 8080; server_name loadbalancer; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; location / { proxy_set_header X-Forward-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; #Timeout after 8 hours proxy_read_timeout 43200000; proxy_connect_timeout 43200000; proxy_redirect off; if (!-f $request_filename) { proxy_pass http://application; break; } } }
我得到：
2016/02/15 08:42:07 [emerg] 21#0: host not found in upstream "application_application_1:8081" in /etc/nginx/sites-enabled/default:3 2016/02/15 08:42:10 [emerg] 22#0: host not found in upstream "application_application_1:8081" in /etc/nginx/sites-enabled/default:3
如何使用主机或IP地址来定义我的nginxconfiguration？ 我没有使用IP地址，因为docker工人可以从已知范围分配不同的IP地址。 有什么build议么？ 我应该在一个docker-compose.yml文件中启动它们吗？
你是否在docker-compose.yml文件中定义了一个到application_application_1的链接 ？
链接做了诀窍：
