Kafka Pod無法從GKE開始

Question

我遵循了本教程 ，當我嘗試在GKE上運行它時，我無法啟動kafka pod。

它CrashLoopBackOff返回CrashLoopBackOff 。 而且我不知道如何顯示pod錯誤日志。

這是當我點擊kubectl describe pod my-pod-xxx ：

我注意到在第一次運行時進展順利，但是此后， Node將狀態更改為NotReady而kafka pod進入了CrashLoopBackOff狀態。

這是下來之前的日志：

誰能告訴我我的吊艙有什么問題，以及如何捕獲吊艙故障的錯誤？

我只是發現集群節點沒有足夠的資源。 創建具有更多內存的新集群后，它可以工作。
