無法從 kubernetes 中的另一個 pod 連接到 Artemis

Question

我有兩個 pod，一個是我的 ArtemisMQ pod，另一個是消費者服務。 我設置了入口，以便我可以訪問有效的控制台，但問題歸結為我的消費者 pod 嘗試訪問端口 61616 進行連接時。

我從我的消費者 Pod 得到的錯誤

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]

Answer 1

將0.0.0.0用於連接器是無效的。 事實上，日志中應該有一條關於它的WARN級別的消息。 使用這種配置將無法正確形成您的集群。 您需要使用其他主機可以用來訪問廣播它的代理的主機名或 IP 地址。 這就是broadcast-group的全部意義——告訴其他可能正在收聽的經紀人他們如何連接到它。

Answer 2

在 minikube 上進行了一些本地測試后，我重建了我的集群並重新部署。 我決定不在這個新集群上部署或重新配置 linkerd，現在一切正常。

所以我遇到的問題一定是針對某些與 linkerd 相關的代理設置。 當我找到通過 linkerd 建立連接的解決方案時，我會跟進這篇文章。
