Docker 安装Kafka

第一步：查看本地镜像、检索Kafka镜像和下载Kafka 镜像

# 查看本地镜像

docker images

# 检索Kafka镜像

docker search kafka

# 下载Kafka 镜像指定版本

docker pull wurstmeister/kafka:latest

[root@localhost ~]# docker images

第二步：启动Zookeeper

Docker 安装ZooKeeper 请参考:Docker安装ZooKeeper

第三步：启动Kafka

docker run -d —name kafka \
-p 9092:9092 \
-e KAFKA_BROKER_ID=0 \
-e KAFKA_ZOOKEEPER_CONNECT=192.168.43.10:2181 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.43.10:9092 \
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 wurstmeister/kafka

[root@localhost ~]# docker run -d --name kafka \

[root@localhost ~]# docker ps

第五步：验证ZooKeeper 和Kafka 容器状态

# 进入ZooKeeper 容器内部

docker exec -it 1c3d38b948ba /bin/bash

# 运行zkCli 客户端指令

zkCli.sh -server 192.168.43.10

[root@localhost ~]# docker exec -it 1c3d38b948ba /bin/bash
root@1c3d38b948ba:/apache-zookeeper-3.7.0-bin# pwd
/apache-zookeeper-3.7.0-bin            
root@1c3d38b948ba:/apache-zookeeper-3.7.0-bin# cd bin/
root@1c3d38b948ba:/apache-zookeeper-3.7.0-bin/bin# zkCli.sh -server 192.168.43.10:2181
[zk: 192.168.43.10:2181(CONNECTING) 0] ls /
[admin, brokers, cluster, config, consumers, controller, controller_epoch, feature, isr_change_notification, latest_producer_id_block, log_dir_event_notification, zookeeper]

[config, quota]
[zk: 192.168.43.10:2181(CONNECTED) 2] quit
WATCHER::
WatchedEvent state:Closed type:None path:null

# 进入Kafka 容器内部

docker exec -it 06a66409d7ce /bin/sh

[root@localhost ~]# docker exec -it 06a66409d7ce /bin/sh
/ # ps -ef
PID   USER     TIME  COMMAND
    1 root      0:30 /usr/lib/jvm/zulu8-ca/bin/java -Xmx1G -Xms1G -server -XX:+
  520 root      0:00 /bin/sh
  526 root      0:00 ps -ef

第六步：Kafka 创建Topic 流程步骤

#进入容器
docker exec -it ${CONTAINER ID} /bin/bash
cd /opt/kafka_2.13-2.8.1/bin
#单机方式：创建一个主题
bin/kafka-topics.sh --create --zookeeper 192.168.43.10:2181 --replication-factor 1 --partitions 1 --topic mykafka
#运行一个生产者
bin/kafka-console-producer.sh --broker-list 192.168.43.10:9092 --topic mykafka
#运行一个消费者
bin/kafka-console-consumer.sh --zookeeper 192.168.43.10:2181 --topic mykafka --from-beginning
