docker怎么部署kafka

小编给大家分享一下docker怎么部署kafka，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

1. 搭建docker

这里我直接用的是docker-compose部署，所以需要提前安装好compose。
既然要用compose那么yml文件自然是少不了的。

首先要新建一个目录，并在目录中新建一个yml文件

文件的内容如下：

version: '2'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    volumes:
      - ./data:/data
    ports:
      - "2181:2181"
       
  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME:127.0.0.1
      KAFKA_MESSAGE_MAX_BYTES: 2000000
      KAFKA_CREATE_TOPICS: "Topic1:1:3,Topic2:1:1:compact"
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - ./kafka-logs:/kafka
      - /var/run/docker.sock:/var/run/docker.sock
 
  kafka-manager:
    image: sheepkiller/kafka-manager
    ports:
      - 9020:9000
    environment:
      ZK_HOSTS: zookeeper:2181

接着利用这个yml文件启动我们的项目

$ docker-compose up -d

可以看到新建了三个容器

2.进入容器

我们通过以下命令进入到kafka容器的交互模式

$ docker exec -it kafkademo01_kafka_1 /bin/bash

因为高版本的kafka内置了zookeeper，所以我们无需进入zookeeper容器。所以yml文件中关于zookeeper的部署是可以省略的。

然后进入kafka的根目录

$ cd /opt/kafka

3.修改配置文件

$ cd /config

首先要修改的是zookeeper的配置文件：zookeeper.properties
（注释已删除）

dataDir=/opt/kafka/zooLogs
clientPort=2182
maxClientCnxns=0
admin.enableServer=false

然后修改kafka的配置文件：server.porperties
（注释已删除）

4.测试kafka

以下是一些基本的命令

启动zookeeper

zookeeper-server-start.sh ../config/zookeeper.properties

启动kafka

kafka-server-start.sh ../config/server.properties

创建一个主题

kafka-topics.sh --create --zookeeper 127.0.0.1:2182 --replication-factor 1 --partitions 1 --topic test

查看创建的主题

kafka-topics.sh --list --zookeeper 127.0.0.1:2182

生产者

kafka-console-producer.sh --broker-list 127.0.0.1:9093 --topic test

消费者

kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9093 --topic test --from-beginning
