docker搭建kafka集群

docker搭建kafka集群docker搭建kafka集群我在M1mbp上使用的以下镜像新建文件zk-kafka-docker-compose.ymlversion:”2″services:zookeeper:user:rootimage:docker.io/zookeeperports:-“12181:2181″environment:-ALLOW_ANONYMOUS_LOGIN=yesvolumes:-zoo

大家好,又见面了,我是你们的朋友全栈君。

一、原生Docker命令

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

二、镜像选择

环境为M1版本的mbp:

  • Zookeeper采用zookeeper

  • Kafka采用wurstmeister/kafka

  • Kafka-Manager采用scjtqs/kafka-manager

  • Mysql采用mysql/mysql-server

三、集群规划

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

hostname Ip addr port listener
zook1 172.20.10.11 2184:2181
zook2 172.20.10.12 2185:2181
zook3 172.20.10.13 2186:2181
kafka1 172.20.10.14 内部9092:9092,外部9192:9192 kafka1
kafka2 172.20.10.15 内部9093:9093,外部9193:9193 kafka2
Kafka3 172.20.10.16 内部9094:9094,外部9194:9194 Kafka3
本机(宿主机Mbp) 172.20.10.2
kafka manager 172.20.10.10 9000:9000

四、Zookeeper集群安装

1. 新建文件zk-docker-compose.yml

version: '3.4'
services:
zook1:
image: zookeeper:latest
restart: always
hostname: zook1
container_name: zook1 #容器名称,方便在rancher中显示有意义的名称
ports:
- 2183:2181 #将本容器的zookeeper默认端口号映射出去
volumes: # 挂载数据卷
- "/Users/konsy/Development/volume/zkcluster/zook1/data:/data"
- "/Users/konsy/Development/volume/zkcluster/zook1/datalog:/datalog"
- "/Users/konsy/Development/volume/zkcluster/zook1/logs:/logs"
environment:
ZOO_MY_ID: 1  #即是zookeeper的节点值,也是kafka的brokerid值
ZOO_SERVERS: server.1=zook1:2888:3888;2181 server.2=zook2:2888:3888;2181 server.3=zook3:2888:3888;2181
networks:
docker-net:
ipv4_address: 172.20.10.11
zook2:   
image: zookeeper:latest
restart: always
hostname: zook2
container_name: zook2 #容器名称,方便在rancher中显示有意义的名称
ports:
- 2184:2181 #将本容器的zookeeper默认端口号映射出去
volumes:
- "/Users/konsy/Development/volume/zkcluster/zook2/data:/data"
- "/Users/konsy/Development/volume/zkcluster/zook2/datalog:/datalog"
- "/Users/konsy/Development/volume/zkcluster/zook2/logs:/logs"
environment:
ZOO_MY_ID: 2  #即是zookeeper的节点值,也是kafka的brokerid值
ZOO_SERVERS: server.1=zook1:2888:3888;2181 server.2=zook2:2888:3888;2181 server.3=zook3:2888:3888;2181
networks:
docker-net:
ipv4_address: 172.20.10.12
zook3:   
image: zookeeper:latest
restart: always
hostname: zook3
container_name: zook3 #容器名称,方便在rancher中显示有意义的名称
ports:
- 2185:2181 #将本容器的zookeeper默认端口号映射出去
volumes:
- "/Users/konsy/Development/volume/zkcluster/zook3/data:/data"
- "/Users/konsy/Development/volume/zkcluster/zook3/datalog:/datalog"
- "/Users/konsy/Development/volume/zkcluster/zook3/logs:/logs"
environment:
ZOO_MY_ID: 3  #即是zookeeper的节点值,也是kafka的brokerid值
ZOO_SERVERS: server.1=zook1:2888:3888;2181 server.2=zook2:2888:3888;2181 server.3=zook3:2888:3888;2181
networks:
docker-net:
ipv4_address: 172.20.10.13
networks:
docker-net:
external:
name: docker-net

2. 执行脚本部署zookeeper至Docker:

docker compose -f ./zk-docker-compose.yml up -d

五、Kafka集群安装

1. 新建文件kafka-docker-compose.yml

version: '2'
services:
kafka1:
image: docker.io/wurstmeister/kafka
restart: always
hostname: kafka1
container_name: kafka1
ports:
- 9093:9093
- 9193:9193
environment:
KAFKA_BROKER_ID: 1
KAFKA_LISTENERS: INSIDE://:9093,OUTSIDE://:9193
#KAFKA_ADVERTISED_LISTENERS=INSIDE://<container>:9092,OUTSIDE://<host>:9094
SKAFKA_ADVERTISED_LISTENERS: INSIDE://kafka1:9093,OUTSIDE://localhost:9193
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
KAFKA_ZOOKEEPER_CONNECT: zook1:2181,zook2:2181,zook3:2181
ALLOW_PLAINTEXT_LISTENER : 'yes'
JMX_PORT: 9999 #开放JMX监控端口,来监测集群数据
volumes:
- /Users/konsy/Development/volume/kafka/kafka1/wurstmeister/kafka:/wurstmeister/kafka
- /Users/konsy/Development/volume/kafka/kafka1/kafka:/kafka
external_links:
- zook1
- zook2
- zook3
networks:
docker-net:
ipv4_address: 172.20.10.14
kafka2:
image: docker.io/wurstmeister/kafka
restart: always
hostname: kafka2
container_name: kafka2
ports:
- 9094:9094
- 9194:9194
environment:
KAFKA_BROKER_ID: 2
KAFKA_LISTENERS: INSIDE://:9094,OUTSIDE://:9194
#KAFKA_ADVERTISED_LISTENERS=INSIDE://<container>:9092,OUTSIDE://<host>:9094
KAFKA_ADVERTISED_LISTENERS: INSIDE://kafka2:9094,OUTSIDE://localhost:9194
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
KAFKA_ZOOKEEPER_CONNECT: zook1:2181,zook2:2181,zook3:2181
ALLOW_PLAINTEXT_LISTENER : 'yes'
JMX_PORT: 9999 #开放JMX监控端口,来监测集群数据
volumes:
- /Users/konsy/Development/volume/kafka/kafka2/wurstmeister/kafka:/wurstmeister/kafka
- /Users/konsy/Development/volume/kafka/kafka2/kafka:/kafka
external_links:
- zook1
- zook2
- zook3
networks:
docker-net:
ipv4_address: 172.20.10.15
kafka3:
image: docker.io/wurstmeister/kafka
restart: always
hostname: kafka3
container_name: kafka3
ports:
- 9095:9095
- 9195:9195
environment:
KAFKA_BROKER_ID: 3
KAFKA_LISTENERS: INSIDE://:9095,OUTSIDE://:9195
#KAFKA_ADVERTISED_LISTENERS=INSIDE://<container>:9092,OUTSIDE://<host>:9094
KAFKA_ADVERTISED_LISTENERS: INSIDE://kafka3:9095,OUTSIDE://localhost:9195
KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE
KAFKA_ZOOKEEPER_CONNECT: zook1:2181,zook2:2181,zook3:2181
ALLOW_PLAINTEXT_LISTENER : 'yes'
JMX_PORT: 9999 #开放JMX监控端口,来监测集群数据
volumes:
- /Users/konsy/Development/volume/kafka/kafka3/wurstmeister/kafka:/wurstmeister/kafka
- /Users/konsy/Development/volume/kafka/kafka3/kafka:/kafka
external_links:
- zook1
- zook2
- zook3
networks:
docker-net:
ipv4_address: 172.20.10.16
networks:
docker-net:
external:
name: docker-net

2. 执行脚本部署kafka至Docker:

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

3. listeners 和 advertised.listeners

  • listeners: 学名叫监听器,其实就是告诉外部连接者要通过什么协议访问指定主机名和端口开放的 Kafka 服务。
  • advertised.listeners:和 listeners 相比多了个 advertisedAdvertised 的含义表示宣称的、公布的,就是说这组监听器是 Broker 用于对外发布的。

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-net

4.2 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

在这里插入图片描述

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
