我在 Kubernetes 上运行 3-zookeeper-cluster 和 3-kafka-cluster。
卡夫卡似乎正在运行。
但是，如果我向某个主题生成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。那就是说一些无效的接收或其他东西，有趣的是试图使主题运作良好但产生。
我也可以观看我早期在 Topics-ui 上制作的主题或模式，Topics-ui 是代理的 GUI 工具。
Schema-registry、Connect、Rest 的日志很好，因此代理似乎运行良好。

这是我使用terraform Statefulset的代理配置

          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"
  }

尝试生成的代码

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

我最初的猜测是您可能正试图接收一个太大的请求。最大大小是 的默认大小socket.request.max.bytes，即 100MB。因此，如果您有大于 100MB 的消息，请尝试在server.properties.

如果您尝试连接到非 SSL 侦听器，也可能发生这种情况，就像它是 SSL 一样。验证 9092 是代理上的 SSL 侦听器端口。来源：https ://github.com/edenhill/librdkafka/issues/1680#issuecomment-364883669
