Docker搭建kafka

一、拉取镜像

docker pull wurstmeister/zookeeper docker pull wurstmeister/kafka

二、检查 docker-compose

docker-compose -v

三、创建 docker-compose.yml 文件

cd /data && mkdir docker-compose && cd docker-compose  touch docker-compose.yml

添加内容

version: '1' services:   zookeeper:     image: zookeeper     hostname: zookeeper     container_name: zookeeper   kafka:     image: wurstmeister/kafka     hostname: kafka     container_name: kafka     ports:       - 9092:9092     environment:       KAFKA_ADVERTISED_HOST_NAME: kafka       KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181 #设置网络,名为local networks:   local:     driver: bridge

四、进入该文件所在目录执行

cd /data/docker-compose docker-compose build

五、启动服务

docker-compose up -d

六、查看容器

docker ps

七、进入容器之中

docker exec -it kafka bash

八、创建topic

kafka-topics.sh --create --zookeeper zookeeper:2181 -replication-factor 1 --partitions 1 --topic mykafka

执行后输出 Created topic mykafka. 表示成功

九、查看topic

kafka-topics.sh --list --zookeeper zookeeper:2181

十、创建生产者

kafka-console-producer.sh --broker-list kafka:9092 --topic mykafka

十一、查看topic内容

kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic mykafka --from-beginning

备注:

经常抛出 host kafka not found的问题,我的做法是更改 /etc/hosts 的域名配置文件,增加一行

127.0.0.1 kafka

我的验证的 java 脚本:

package com.example.one.kafka; import java.util.Properties; import org.apache.kafka.clients.producer.Producer; import org.apache.kafka.clients.producer.KafkaProducer; import org.apache.kafka.clients.producer.ProducerRecord; import org.apache.kafka.common.serialization.StringSerializer;  // 示例地址: https://www.yiibai.com/kafka/apache_kafka_simple_producer_example.html public class SimpleProducer {     public static void main(String[] args) throws Exception {         //Assign topicName to string variable         String topicName = mykafka;         // create instance for properties to access producer configs         Properties props = new Properties();         //Assign localhost id         props.put(bootstrap.servers, localhost:9092);         //Set acknowledgements for producer requests.         props.put(acks, all);         //If the request fails, the producer can automatically retry,         props.put(retries, 0);         //Specify buffer size in config         props.put(batch.size, 16384);         //Reduce the no of requests less than 0         props.put(linger.ms, 1);         //The buffer.memory controls the total amount of memory available to the producer for buffering.         props.put(buffer.memory, 33554432);         props.put(key.serializer,org.apache.kafka.common.serialization.StringSerializer);         props.put(value.serializer,org.apache.kafka.common.serialization.StringSerializer);          Producer<String, String> producer = new KafkaProducer                 <String, String>(props);          for (int i = 8; i < 19; i++)             producer.send(new ProducerRecord<String, String>(topicName,                     Integer.toString(i), Integer.toString(i)));         System.out.println(Message sent successfully);         producer.close();     } }
