Question

我多次遇到问题，通过重新创建问题应用程序修复它，但我仍然想知道如何调试以及导致此问题的原因。

例如：我在我的主人中创建了一个新的应用程序jenkins持久应用程序，我能够在Node / Master中卷曲端点IP地址，但无法卷曲应用程序暴露的IP /主机名地址。有时，我只需要删除应用程序然后重新创建，这个问题将得到解决，但这次我真的想知道如何修复它而不重新创建，按照https://docs.openshift.com/enterprise/3.1/admin_guide/sdn_troubleshooting.html中的文章进行调试，而且我很确定DNS正在运行，如果我需要在这里提供更多信息，请告诉我。谢谢。

这是我的svc描述输出：
