kubernetes - 无法从kubernetes中的另一个Pod连接到Artemis

Question

我有两个 pods ，一个是我的ArtemisMQ pods ，另一个是消费者服务。
我已经设置了入口，以便可以访问可正常使用的控制台，但是问题归结为当我的客户Pod尝试访问端口61616进行连接时。
我从消费者 pods 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

对连接器使用0.0.0.0无效。实际上，关于它的日志中应该有一个WARN级别的消息。使用这样的配置，您的群集将无法正确形成。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的全部要点-告诉其他可能正在侦听他们如何连接到它的经纪人。
