kubernetes - Kafka Producer导致org.apache.kafka.common.network.InvalidReceiveException:无效的接收

Question

我在Kubernetes上运行3-zookeeper-cluster和3-kafka-cluster。
Kafka似乎正在运行。
但是，如果我向某个主题发出一些消息并检查该主题，则根本没有消息。

这是我的经纪人说的。那表示有些无效的接收或某些东西，有趣的是试图使主题正常工作但产生。
我也可以观看主题或架构，这些主题或架构是我在Topics-ui(代理人的GUI工具)上早期制作的。
模式注册表，连接，Rest的日志很好，因此代理似乎运行良好。

这是我的代理配置 terraform
Statefulset

          port {
            container_port = 9092
          }   

          env {
            name = "KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR" 
            value = "3" 
          }   

          env {
            name = "KAFKA_DEFAULT_REPLICATION_FACTOR" 
            value = "3" 
          }   

          env {
            name = "KAFKA_LISTENER_SECURITY_PROTOCOL_MAP" 
            value = "PLAINTEXT:PLAINTEXT,EXTERNAL:PLAINTEXT"
          }   

          env {
            name = "KAFKA_ZOOKEEPER_CONNECT"
            value = "lucent-zookeeper-0.zookeeper-service.default:2181,lucent-zookeeper-1.zookeeper-service.default:2181,lucent-zookeeper-2.zookeeper-service.default:2181"
          }   

          env {
            name = "POD_IP"

            value_from {
              field_ref {
                field_path = "status.podIP"
              }   
            }   
          }   

          env {
            name = "HOST_IP"
            value_from {
              field_ref {
                field_path = "status.hostIP"
              }   
            }   
          }   

          env {
            name = "POD_NAME"

            value_from {
              field_ref {
                field_path = "metadata.name"
              }   
            }   
          }   

          env {
            name = "POD_NAMESPACE"

            value_from {
              field_ref {
                field_path = "metadata.namespace"
              }   
            }   
          }   

          command = [ 
            "sh",
            "-exec",
            "export KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://$${POD_NAME}.kafka-service.$${POD_NAMESPACE}:9092 && export KAFKA_BROKER_ID=$${HOSTNAME##*-} && exec /etc/confluent/docker/run"
          ]   

服务

resource "kubernetes_service" "kafka-service" {
  metadata {
    name = "kafka-service"

    labels = {
      app = "broker" 
    }
  }

  spec {
    selector = {
      app = "broker"
    }

    port {
      port = 9092
    }

    cluster_ip = "None"
  }

代码尝试生成

kafka-console-producer --broker-list kafka-service:9092 --topic test

我最初的猜测是您可能试图接收太大的请求。最大大小是socket.request.max.bytes的默认大小，为100MB。因此，如果收到的消息大于100MB，请尝试在server.properties下增加此变量的值。
