目录一、原生Docker命令二、镜像选择三、集群规划四、ZooKeeper集群安装五、kafka集群安装一、原生Docker命令 1. 删除所有dangling数据卷（即无用的Vol
1. 删除所有dangling数据卷（即无用的Volume，僵尸文件）
docker volume rm $(docker volume ls -qf dangling=true)
2. 删除所有dangling镜像（即无tag的镜像）
docker rmi $(docker images | grep "^<none>" | awk "{print $3}"
3. 删除所有关闭的容器
docker ps -a | grep Exit | cut -d ' ' -f 1 | xargs docker rm
环境为M1版本的mbp:
1. 新建docker网络
docker network create docker-net --subnet 172.20.10.0/16
docker network ls
2. 集群规划

docker compose -f ./kafka-docker-compose.yml up -d
3. listeners 和 advertised.listeners
比如说：
listeners: INSIDE://172.17.0.10:9092,OUTSIDE://172.17.0.10:9094
advertised_listeners: INSIDE://172.17.0.10:9092,OUTSIDE://<公网 ip>:端口
kafka_listener_security_protocol_map: "INSIDE:SASL_PLAINTEXT,OUTSIDE:SASL_PLAINTEXT"
kafka_inter_broker_listener_name: "INSIDE"
advertised_listeners 监听器会注册在 zookeeper 中；
当我们对 172.17.0.10:9092 请求建立连接，kafka 服务器会通过 zookeeper 中注册的监听器，找到 INSIDE 监听器，然后通过 listeners 中找到对应的 通讯 ip 和 端口；
同理，当我们对 <公网 ip>:端口 请求建立连接，kafka 服务器会通过 zookeeper 中注册的监听器，找到 OUTSIDE 监听器，然后通过 listeners 中找到对应的 通讯 ip 和 端口 172.17.0.10:9094；
总结：advertised_listeners 是对外暴露的服务端口，真正建立连接用的是 listeners。
4.安装kafka-manager
4.1 新建文件kafka-manager-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
- zook2
- zook3
- kafka1
- kafka2
- kafka3
environment:
ZK_HOSTS: zook1:2181,zook2:2181,zook3:2181
KAFKA_BROKERS: kafka1:9093,kafka2:9094,kafka3:9095
APPLICATION_SECRET: letmein
KM_ARGS: -Djava.net.preferIPv4Stack=true
networks:
docker-net:
ipv4_address: 172.20.10.10
networks:
docker-net:
external:
name: docker-net4.2 执行脚本部署kafka-manager至Docker:
docker compose -f ./kafka-manager-docker-compose.yml up -d
4.3 配置Cluster
5. 测试kafka
5.1连接容器
进入kafka容器的命令行：
docker exec -ti kafka /bin/bash
进入kafka所在目录：
cd opt/kafka_2.13-2.8.1/
5.2 创建Replication为2，Partition为2的topic
bin/kafka-topics.sh --create --zookeeper zook1:2181 --replication-factor 2 --partitions 2 --topic partopic
5.3 查看topic的状态
在kafka容器中的 opt/kafka_2.12-1.1.0/ 目录下输入
bin/kafka-topics.sh --describe --zookeeper zook1:2181 --topic partopic
