无法从 kubernetes 中的另一个 pod 连接到 Artemis

Question

我有两个 pod，一个是我的 ArtemisMQ pod，另一个是消费者服务。 我设置了入口，以便我可以访问有效的控制台，但问题归结为我的消费者 pod 尝试访问端口 61616 进行连接时。

我从我的消费者 Pod 得到的错误

Could not refresh JMS Connection for destination 'PricingSave' - retrying using FixedBackOff{interval=5000, currentAttempts=0, maxAttempts=unlimited}. Cause: Failed to create session factory; nested exception is ActiveMQConnectionTimedOutException[errorType=CONNECTION_TIMEDOUT message=AMQ219013: Timed out waiting to receive cluster topology. Group:null]

我的经纪人配置：

Answer 1

将0.0.0.0用于连接器是无效的。 事实上，日志中应该有一条关于它的WARN级别的消息。 使用这种配置将无法正确形成您的集群。 您需要使用其他主机可以用来访问广播它的代理的主机名或 IP 地址。 这就是broadcast-group的全部意义——告诉其他可能正在收听的经纪人他们如何连接到它。

Answer 2

在 minikube 上进行了一些本地测试后，我重建了我的集群并重新部署。 我决定不在这个新集群上部署或重新配置 linkerd，现在一切正常。

所以我遇到的问题一定是针对某些与 linkerd 相关的代理设置。 当我找到通过 linkerd 建立连接的解决方案时，我会跟进这篇文章。
