Hono适配器无法连接到群集

Question

我目前正在安装hono与enmasse一起安装在openshift/okd之上。除了适配器和群集之间的连接之外，一切都进行得很好。例如，当我部署amqp适配器(也发生在http和mqtt适配器上)时，我将从hono适配器获得以下日志记录：

以下是成批日志：

更多信息：

• Hono版本: 0.8.x
• 整体版本: 0.24.1

谁能告诉我我错过了什么吗？

谢谢!PS:如果有足够声誉的人能添加一个新的“集合”标签，那就太好了。

Answer 1

我已经找到了解决这个问题的办法。

首先:框架错误不是来自hono的传入连接。在没有安装hono的情况下安装enmasse时，我已经看到了这个日志记录。我不知道他们从哪里来。如果有人有主意，请告诉我。

至于真正的问题:我似乎需要允许这两个项目(enmasse和hono)之间的交流。这在Openshift文档上有记录。

TLDR

• 使用的解决方案：oc adm pod-network make-projects-global enmasse-infra。我之所以这样做，是因为enmasse框架需要所有项目都可以访问(包括hono，但也包括同上和我们的定制后端应用程序)。
• 也应该工作(没有测试)：oc adm pod-network join-projects --to=enmasse-infra hono
