Question

我正在尝试在同一台计算机上的多个端口上侦听多个应用程序。所有应用均基于docker容器。我希望每个应用程序都有不同的子域名。

我有以下设置：

带有SSL的

ELB转发到特定的CNAME，最终将转发到端口80的EC2实例流量。在EC2实例上，我有一个here来运行的nginx容器。我有一个docker容器，它公开了端口3001并设置了配置了子域的虚拟主机，如链接中所述。

我正在尝试将每个http请求重定向到实例中容器的子域sub.example.com。

我一直从nginx和以下错误日志中获取502：

2018/07/14 08:45:58 [错误] 137＃137：* 20连接到上游时，connect（）失败（111：连接被拒绝），客户端：111.111.111.11，服务器：sub.example.com ，请求：“ GET / HTTP / 1.1”，上游：“ http://172.17.0.2:3001/”，主机：“ sub.example.com”

我要到达的容器是172.17.0.2。

这是nginx从容器中获取的默认conf：
