kafka的Docker镜像使用说明(wurstmeister/kafka)

提醒

在hub.docker.com网站上,Star最多的kafka镜像是wurstmeister/kafka,今天一起来实践这个镜像,使用此镜像搭建kafka环境,并且生产和消费消息;
https://developer.aliyun.com/article/988818

实战环境

操作系统:CentOS7
Docker:24.0.2
docker-compose:v2.18.1

编写docker-compose.yml

启动server

在docker-compose.yml所在的文件夹下,执行命令

docker compose up -d

,会先下载zookeeper和kafka的镜像,然后创建容器;
执行命令

docker compose ps

,可见启动了一个zookeeper和三个kafka容器:

[root@hecs-334217 kafka-compose]# docker compose ps
NAME                IMAGE                    COMMAND                  SERVICE             CREATED             STATUS              PORTS
kafka-0             wurstmeister/kafka       "start-kafka.sh"         kafka-0             28 minutes ago      Up 28 minutes       0.0.0.0:9093->9093/tcp, :::9093->9093/tcp
kafka-1             wurstmeister/kafka       "start-kafka.sh"         kafka-1             28 minutes ago      Up 28 minutes       0.0.0.0:9094->9094/tcp, :::9094->9094/tcp
kafka-2             wurstmeister/kafka       "start-kafka.sh"         kafka-2             28 minutes ago      Up 28 minutes       0.0.0.0:9095->9095/tcp, :::9095->9095/tcp
zookeeper           wurstmeister/zookeeper   "/bin/sh -c '/usr/sb…"   zookeeper           28 minutes ago      Up 28 minutes       22/tcp, 2888/tcp, 3888/tcp, 0.0.0.0:2181->2181/tcp, :::2181->2181/tcp

查看版本号

执行以下命令查看容器中的kafka版本号:

[root@hecs-334217 kafka-compose]# docker exec kafka-0 find / -name \*kafka_\* | head -1 |grep -o '\kafka[^\n]*'
kafka_2.13-2.8.1

上述命令执行后,我这边控制台显示kafka_2.11-0.11.0.3,这表示Scala 的版本为2.11,kafka的版本是0.11.0.3;
执行以下命令查看zookeeper版本:

[root@hecs-334217 kafka-compose]# docker exec zookeeper pwd
/opt/zookeeper-3.4.13

创建topic

创建一个topic,名为topic001,3个partition,副本因子2,执行以下命令即可:

[root@hecs-334217 kafka-compose]# docker exec kafka-1 kafka-topics.sh --create --topic topic001 --partitions 3 --zookeeper zookeeper:2181 --replication-factor 2
Created topic topic001.

执行以下命令查看刚刚创建的topic,这次在容器kafka-2上执行命令试试:

[root@hecs-334217 kafka-compose]# docker exec kafka-2 kafka-topics.sh --list --zookeeper zookeeper:2181
test
topic001

可见刚刚创建的topic可以被查到;
查看刚刚创建的topic的情况,borker和副本情况一目了然,如下:

[root@hecs-334217 kafka-compose]# docker exec kafka-0 kafka-topics.sh --describe --topic topic001 --zookeeper zookeeper:2181
Topic: topic001 TopicId: umQtyLTtQQCeMG8W5bWcpA PartitionCount: 3       ReplicationFactor: 2    Configs: 
        Topic: topic001 Partition: 0    Leader: 0       Replicas: 0,1   Isr: 0,1
        Topic: topic001 Partition: 1    Leader: 1       Replicas: 1,2   Isr: 1,2
        Topic: topic001 Partition: 2    Leader: 2       Replicas: 2,0   Isr: 2,0

消费消息

执行如下命令,即可进入等待topic为topic001消息的状态:

docker exec kafka-2 \
kafka-console-consumer.sh \
--topic topic001 \
--bootstrap-server kafka-0:9093,kafka-1:9094,kafka-2:9095

目前还没有生产消息,因此控制台不会有内容输出,接下来尝试生产消息;

生产消息

打开一个新的窗口,执行如下命令,进入生产消息的命令行模式,注意不要漏掉参数"-it"

docker exec -it kafka-1 \
kafka-console-producer.sh \
--topic topic001 \
--broker-list kafka-0:9093,kafka-1:9094,kafka-2:9095

现在已经进入了生产消息的命令行模式,输入一些字符串然后回车,再去消费消息的控制台窗口看看,已经有消息打印出来,说明消息的生产和消费都成功了。
在这里插入图片描述

docker compose 命令

# 启动:
$ docker compose up -d  # docker-compose up -d 这种是旧版的,新版本已经抛弃了# 查看compose容器
$ docker compose ps# 删除容器:
$ docker compose down
