Docker按键kafka

Docker按键kafka 搭建方法一

分别搭建参考Docker搭建Kafka

下载镜像

docker pull wurstmeister/kafka 
docker pull zookeeper

单机启动zookeeper

docker run -d --name zookeeper -p 2181:2181 -t zookeeper:latest

单机启动kafka

docker run -d --name kafka 
-p 9092:9092 
-e KAFKA_BROKER_ID=0 
-e KAFKA_ZOOKEEPER_ConNECT=192.168.8.208:2181 
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.8.208:9092 
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 wurstmeister/kafka

创建一个topic

#进入容器
docker exec -it ${ConTAINER ID} /bin/bash
cd opt/bin
#单机方式：创建一个主题
# opt/kafka/bin/
# 172.17.0.2 通过docker inspect zookeeper获取zookeeper的ip地址
./kafka-topics.sh --create --zookeeper 172.17.0.2:2181 --replication-factor 1 --partitions 1 --topic mykafka
#运行一个生产者
./kafka-console-producer.sh --broker-list localhost:9092 --topic mykafka
#运行一个消费者
./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic mykafka --from-beginning

搭建方法二

同时搭建参考docker部署kafka

拉取镜像

docker pull wurstmeister/kafka 
docker pull zookeeper

定义docker-compose.yml

version: '2.2'
services:
  zookeeper:
    image: zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka
    depends_on: [ zookeeper ]
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: 192.168.8.208
      KAFKA_CREATE_TOPICS: "test:1:1"
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      # 需要在本地找到目录
      - ${HOME}/docker/kafka/docker.sock:/var/run/docker.sock

docker-compose.yml所在文件夹打包

zzw@zhaozhenwei-Mac-mini kafka % docker-compose build
zookeeper uses an image, skipping
kafka uses an image, skipping

启动

zzw@zhaozhenwei-Mac-mini kafka % docker-compose up -d       
Starting kafka_zookeeper_1 ... done
Starting kafka_kafka_1     ... done

关闭所有镜像

docker stop $(docker ps -q)

使用

# 新建topic
$KAFKA_HOME/bin/kafka-topics.sh --create --topic mykafka --partitions 4 --zookeeper kafka_zookeeper_1:2181 --replication-factor 1

# 查看topic
$KAFKA_HOME/bin/kafka-topics.sh --zookeeper kafka_zookeeper_1:2181 --describe --topic mykafka
Topic: mykafka	PartitionCount: 4	ReplicationFactor: 1	Configs: 
	Topic: mykafka	Partition: 0	Leader: 1001	Replicas: 1001	Isr: 1001
	Topic: mykafka	Partition: 1	Leader: 1001	Replicas: 1001	Isr: 1001

	Topic: mykafka	Partition: 3	Leader: 1001	Replicas: 1001	Isr: 1001

# 创建生产者
$KAFKA_HOME/bin/kafka-console-producer.sh --topic=mykafka --broker-list kafka_kafka_1:9092

# 创建消费者
$KAFKA_HOME/bin/kafka-console-consumer.sh --bootstrap-server kafka_kafka_1:9092 --from-beginning --topic mykafka
