kafka(kraft模式)3.*集群容器部署 docker-compose

一、创建yml文件
要修改部分
1.修改宿主机ip KAFKA_CFG_ADVERTISED_LISTENERS
2.修改挂载路径

version: "3.6"
services:
  kafka1:
    container_name: kafka1
    image: 'bitnami/kafka:3.3.1'
    user: root
    ports:

      - KAFKA_CFG_PROCESS_ROLES=broker,controller
      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
      # 定义kafka服务端socket监听端口（Docker内部的ip地址和端口）
      - KAFKA_CFG_LISTENERS=PLAINTEXT://:9092,CONTROLLER://:9093
      # 定义安全协议
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT

#kafka图形 有需要时部署
#  kafka-manager:
#    container_name: kafka-manager
#    image: sheepkiller/kafka-manager
#    ports:
#      - 9020:9000
#    environment:
#      ZK_HOSTS: zookeeper:2181

二、启动

docker-compose -f kafka.yml up -d

三、测试

#3.1进入容器
docker exec -it kafka1 bash 

#3.2进入kafka目录
cd /opt/bitnami/kafka/bin

#3.3 创建Topic  
#创建一个副本为3、分区为5的topic
./kafka-topics.sh --create --topic foo --partitions 5 --replication-factor 3 --bootstrap-server kafka1:9092,kafka2:9092,kafka3:9092

Created topic foo.

#查看topic详细信息
kafka-topics.sh --describe --topic foo --bootstrap-server kafka1:9092, kafka2:9092, kafka3:9092

Topic: foo      TopicId: 83kWG4PUT9u4fOzG5WgFoA PartitionCount: 5       ReplicationFactor: 3    Configs:
        Topic: foo      Partition: 0    Leader: 3       Replicas: 3,1,2 Isr: 3,1,2
        Topic: foo      Partition: 1    Leader: 1       Replicas: 1,2,3 Isr: 1,2,3
        Topic: foo      Partition: 2    Leader: 2       Replicas: 2,3,1 Isr: 2,3,1
        Topic: foo      Partition: 3    Leader: 3       Replicas: 3,2,1 Isr: 3,2,1
        Topic: foo      Partition: 4    Leader: 2       Replicas: 2,1,3 Isr: 2,1,3

#3.4生产和消费验证
#开出量个窗口  进到相同容器相同目录
kafka1生产：kafka-console-producer.sh --broker-list 172.23.0.11:9092,172.23.0.12:9092,172.23.0.13:9092 --topic foo
kafka2和kafka3消费：kafka-console-consumer.sh --bootstrap-server 172.23.0.11:9092,172.23.0.12:9092,172.23.0.13:9092 --topic foo

#3.5删除Topic
kafka-topics.sh --delete --topic foo --bootstrap-server kafka1:9092,kafka2:9092,kafka3:9092
