使用 strimzi 在 Openshift 上设置 Kafka

本文介绍了使用 strimzi 在 Openshift 上设置 Kafka的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在尝试使用本指南在 Openshift 平台上设置 kafka 集群:当我的应用程序作为引导服务器运行时，我将路由输入到 my-cluster-kafka-external 引导程序.但是当我尝试向 Kafka 发送消息时，我收到了这条消息:21:32:40.548 [http-nio-8080-exec-1] 错误 osksLoggingProducerListener () - 发送带有 key='key' 和 payload='Event(id=null,number=30446C77213B40000004tgst15, itemId=, serialNumber=0, locat...' to topic tag-topic:org.apache.kafka.common.errors.TimeoutException:60000 毫秒后无法更新元数据.主题已成功创建，应用程序在我的计算机上使用本地 kafka 运行时运行良好.那么我做错了什么，为什么我不能访问Kafka并发送消息?这是我在 spring-kafka 中的 kafka 生产者配置: @Value("${kafka.bootstrap-servers}")私有字符串引导服务器；@豆角，扁豆公共地图生产者配置(){映射props = new HashMap();props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer");props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "........kafka.EventSerializer");props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);返回道具；}@豆角，扁豆公共 ProducerFactory生产者工厂(){返回新的 DefaultKafkaProducerFactory<>(producerConfigs());}我将日志记录级别设置为调试并发现:23:59:27.412 [org.springframework.kafka.KafkaListenerEndpointContainer#0-0-C-1] DEBUG OakcNetworkClient() -

But when I try to send a message to Kafka i get this message:21:32:40.548 [http-nio-8080-exec-1] ERROR o.s.k.s.LoggingProducerListener () - Exception thrown when sending a message with key='key' and payload='Event(id=null, number=30446C77213B40000004tgst15, itemId=, serialNumber=0, locat...' to topic tag-topic:org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms.The topic was successfully created and the application runs fine when running with local kafka on my computer. So what am I doing wrong, why can't I access Kafka and send messages?Here is my kafka producer config in spring-kafka: @Value("${kafka.bootstrap-servers}") private String bootstrapServers; @Bean public Map<String, Object> producerConfigs() { Map<String, Object> props = new HashMap<>(); props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer"); props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "........kafka.EventSerializer"); props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers); return props; } @Bean public ProducerFactory<String, Event> producerFactory() { return new DefaultKafkaProducerFactory<>(producerConfigs()); }EDIT:I set the logging level to debug and found this:23:59:27.412 [org.springframework.kafka.KafkaListenerEndpointContainer#0-0-C-1] DEBUG o.a.k.c.NetworkClient () - [Consumer clientId=consumer-1, groupId=id] Initialize connection to node my-cluster-kafka-bootstrap-kafka-test...............

Here someone had a similar problem.I tried using kafka-console-producer by running this command:bin\windows\kafka-console-producer --broker-list https://my-cluster-kafka-bootstrap-kafka-test.domain.com:443 --topic tag-topic --producer.config config/producer.propertiesand with this configuration in the producer.properties:compression.type=nonesecurity.protocol=SSLssl.truststore.location=C:\\Tools\\kafka_2.12-2.2.0\\config\\store.jksssl.truststore.password=passwordssl.keystore.location=C:\\Tools\\kafka_2.12-2.2.0\\config\\store.jksssl.keystore.password=passwordssl.key.password=passwordbut I get a response saying that the connection was terminated while authenticating:[2019-05-21 16:15:58,444] WARN [Producer clientId=console-producer] Connection to node 1 (my-cluster-kafka-1-kafka-test.domain.com/52.xxx.xx.40:443) terminated during authentication. This may happen due to any of the following reasons: (1) Authentication failed due to invalid credentials with brokers older than 1.0.0, (2) Firewall blocking Kafka TLS traffic (eg it may only allow HTTPS traffic), (3) Transient network issue. (org.apache.kafka.clients.NetworkClient)Is there any way that the certificate from openshift is wrong? 解决方案 The access through routes is possible via TLS only using the CA certificate generated by Strimzi that you have to extract as described in the article. Then you have to create a key store importing the certificate and providing that to the client application. I don't see such configuration in your producer. 这篇关于使用 strimzi 在 Openshift 上设置 Kafka的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
