问题描述
我们正在尝试通过azure kubernetes集群中的java docker容器通过websocket通过amqp与azure iothub进行通信。令人遗憾的是，容器无法在本地甚至在另一个虚拟机（仅安装了docker的虚拟机）上建立连接，容器运行成功。
网络策略规则应允许所有必要的协议和端口与iot集线器的eventhub端点进行通信。
有人知道我们必须拉哪个开关才能从群集中“允许”容器与iothub进行通信吗？
我们仅有的日志是：

解决方法
故障根本就不是网络。
我的错误是，我认为如果我可以通过docker run -it *运行容器手册，那么它也应该可以在kubernetes集群中工作。但是使用-it参数时，容器保持打开状态，并附加了伪tty。但是在kubernetes集群中，这种原因不会发生，因此我们必须调整Java应用程序的循环逻辑，然后它才能工作。
