1. pull镜像
docker pull zookeeper
docker pull wurstmeister/kafka
2. 创建通信网络。zookeeper和kafka之间的通信
docker network create kafka_zk_net
查看网络
docker network ls
docker network inspect kafka_zk_net
3. 创建容器
docker run --net=kafka_zk_net --name zookeeper -p 21810:2181 -d docker.io/zookeeper
docker run --net=kafka_zk_net --name kafka -p 9093:9092 \
--link zookeeper \
-e KAFKA_BROKER_ID=4 \
-e KAFKA_ZOOKEEPER_ConNECT=172.18.0.2:2181 \
-e KAFKA_ADVERTISED_HOST_NAME=43.142.80.86 \
-e KAFKA_ADVERTISED_PORT=9092 \
-d wurstmeister/kafka
KAFKA_ADVERTISED_HOST_NAME参数需要设置为宿主机地址(或服务器外网地址)
KAFKA_ZOOKEEPER_CONNECT参数设置zookeeper容器内部地址和端口,查看指令为docker inspect kafka_zk_net
"a3300202308bec58530baaa31247f1870def61f07208e72b18ab10f0bb44c5d9": {
"Name": "zookeeper",
"EndpointID": "ae59143a1679b7534df41b9a0aa44164c26a6841a04893a3053f14c73cbe2df9",
"MacAddress": "02:42:ac:12:00:02",
"IPv4Address": "172.18.0.2/16",
"IPv6Address": ""
}
4. 启动生产者和消费者
docker exec -it kafka bash
cd opt/kafka_2.13-2.8.1/bin/
./kafka-console-producer.sh --bootstrap-server localhost:9092 --topic topic1 生产者
./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topic1 --from-beginning 消费者
5. bug
1. 启动consumer发现: Error while fetching metadata with correlation id
修复步骤:
vi /opt/kafka/kafka/config/server.properties
添加:
listeners=PLAINTEXT://localhost:9092
advertised.listeners=PLAINTEXT://localhost:9092
kafka listeners和advertised配置
发现:Docker：bash: vi: command not found
apt-get update
apt-get install vim
停止kafka容器和重启
docker stop kafka
docker restart kafka
docker restart kafka
成功截图
ps:如果你修改容器文件导致无法启动容器可以参考:
Docker容器无法启动,里面的配置文件如何修改
非内网连接,必须构建时指定端口和网址...测试了一下,修改是没用的,应该zookeeper已经存了元数据了..
docker run --net=kafka_zk_net --name kafka -p 9093:9092 \
--link zookeeper \
-e KAFKA_BROKER_ID=4 \
-e KAFKA_ZOOKEEPER_ConNECT=172.18.0.2:2181 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://43.142.80.86:9093 \
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 \
-d wurstmeister/kafka*/
