Question

我在IBM Bluemix中有两个docker容器。一个是MQTT和其他php-python。

PHP应用程序执行一个python脚本，该脚本应该连接到MQTT docker容器并订阅一个主题。

然而，php-python docker无法连接。它也无法ping到MQTT docker容器。

MQTT容器工作正常，因为我可以从本地计算机连接到它。

我尝试使用以下命令链接两个容器：

cf ic run -p 443 -p 80 --name connector --link moscacontainer:source 
registry.ng.bluemix.net/fortspace/php-mqtt

我已经为MQTT容器公开了端口1883和80。

我使用以下链接作为参考：

https://github.com/dceejay/nrdock/blob/master/README.md#linking-containers

有人可以指导吗？

编辑： cf ic的输出检查

您可以查看此页面中的信息： https://console.ng.bluemix.net/docs/containers/container_linking.html

我担心--link是不正确的，您可能需要确保别名和名称是正确的。

此命令输出应该可以帮助您： cf ic inspect recipient_container_name

Inter docker通信（mqtt和python）
