docker下搭建kafka集群

创建docker-compose.yml文件，分别是zookeeper、kafka、kafka-manager

zk-docker-compose.yml

version: '2'

services:
  kafka-manager:
    image: scjtqs/kafka-manager:latest
    restart: always
    hostname: kafka-manager
    container_name: kafka-manager
    ports:
      - 9000:9000
    external_links:  # 连接本compose文件以外的container
      - zook1
      - kafka1
      - kafka2
      - kafka3
    environment:
      ZK_HOSTS: zook1:2181

kafka-manager-docker-compose.yml

依次执行yml文件，生成本地镜像与容器

1	`docker compose -p zookeeper -f ./zk-docker-compose.yml up -d`

1	`docker compose -f ./kafka-docker-compose.yml up -d`

1	`docker compose -f ./kafka-manager-docker-compose.yml up -d`

查看生成的结果

mac docker desktop中查看

执行kafka*.sh遇见以下错误

1	`kafka Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 9999; nested exception is: java.net.BindException: Address already in use (Bind failed)`

需要修改 kafka-run-class.sh

ISKAFKASERVER="false"
if [[ "$*" =~ "kafka.Kafka" ]]; then
    ISKAFKASERVER="true"
fi
if [  $JMX_PORT ] && [ -z "$ISKAFKASERVER" ]; then
  KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT "
fi

进入容器,创建topic

docker exec -it kafka1 /bin/bash
 
cd opt/kafka
 
./bin/kafka-topics.sh --create --zookeeper zook1:2181 --replication-factor 1 --partitions 1 --topic businessLogs
