Hono 适配器无法连接到 enmasse

Question

我目前正在 openshift/okd 上安装 hono 和 enmasse。除了适配器和 enmasse 之间的连接外，一切都很好。例如，当我部署 amqp 适配器时（也发生在 http 和 mqtt 适配器上），我从 hono 适配器获得以下日志记录：

收集以下日志：

附加信息：

• Hono 版本：0.8.x
• Enmasse 版本：0.24.1

谁能告诉我我错过了什么？
谢谢！ PS：如果有足够声誉的人可以添加一个新的“enmasse”标签，那就太好了。

Answer 1

我已经找到了解决这个问题的方法。
首先：帧错误不是来自hono的传入连接。我已经在安装 enmasse 而没有安装 hono 的情况下看到了这个日志记录。我不知道他们从哪里来。如果有人有想法，请告诉我。
至于真正的问题：似乎我需要允许两个项目（enmasse-infra 和 hono）之间的通信。这记录在 Openshift documentation。
TLDR

• 使用的解决方案：oc adm pod-network make-projects-global enmasse-infra。我之所以使用这个，是因为所有项目（包括 hono 以及同上以及我们的自定义后端应用程序）都需要访问 enmasse 框架。
• 应该也可以工作（未经测试）：oc adm pod-network join-projects --to=enmasse-infra hono
