openshift - Hono 适配器无法连接到 enmasse

问题描述

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 适配器得到以下日志记录：

Enmasse 日志如下：

2019-01-07 12:36:24.962160 +0000 SERVER (info) [160]: Accepted connection to 0.0.0.0:5672 from 10.128.0.1:44664

附加信息：

有人可以告诉我我错过了什么吗？
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。

解决方案

我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。在安装 enmasse 而不安装 hono 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 文档中。
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。
  • 也应该工作（未测试）：oc adm pod-network join-projects --to=enmasse-infra hono
