docker kafka 单节点
宿主机IP: 192.168.43.177
1.下载镜像
这里使用了wurstmeister/kafka和wurstmeister/zookeeper这两个版本的镜像
docker pull wurstmeister/zookeeper
docker pull wurstmeister/kafka
在命令中运行docker images验证两个镜像已经安装完毕
2.启动
启动zookeeper容器
docker run -d --name zookeeper -p 2181:2181 -t wurstmeister/zookeeper
启动kafka容器
docker run -d --name kafka -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.43.177:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.43.177:9092 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 -t wurstmeister/kafka
3.进入容器操作：
cd /opt/kafka_2.12-2.3.0/bin
创建主题
sh kafka-topics.sh --create --zookeeper 192.168.43.177:2181 --replication-factor 1 --partitions 2 --topic test
删除主题【需要在server.properties中设置delete.topic.enable=true】
sh kafka-topics.sh --delete --zookeeper 192.168.43.177:2181 --topic test
查看主题：
sh kafka-topics.sh --list --zookeeper 192.168.43.177:2181
sh kafka-topics.sh --describe --zookeeper 192.168.43.177:2181 --topic test
生产消息：
sh kafka-console-producer.sh --broker-list 192.168.43.177:9092 --topic test
消费消息：
sh kafka-console-consumer.sh --bootstrap-server 192.168.43.177:9092 --from-beginning --topic test
sh kafka-consol e-consumer.sh --bootstrap-server 192.168.43.177:9092 --topic test

docker kafka 集群部署
宿主机IP: 192.168.43.177
1.下载镜像
这里使用了wurstmeister/kafka和zookeeper这两个版本的镜像
docker pull zookeeper
docker pull wurstmeister/kafka
在命令中运行docker images验证两个镜像已经安装完毕
2.编写docker-kafka.yml文件，内容如下：
version: '2'

3.创建kafka集群，宿主机docker-kafka.yml文件目录下执行
docker-compose -f docker-kafka.yml up -d
4.修改宿主机或其他客户端主机hosts配置，增加以下配置
192.168.43.177 kafka1
192.168.43.177 kafka2
192.168.43.177 kafka3
相关命令：
停止容器：
docker stop zoo1 zoo2 zoo3 kafka1 kafka2 kafka3
删除容器：
docker rm zoo1 zoo2 zoo3 kafka1 kafka2 kafka3
创建主题：
sh kafka-topics.sh --create --zookeeper 192.168.43.177:2181,192.168.43.177:2182,192.168.43.177:2183 --replication-factor 1 --partitions 2 --topic test
查看主题：
sh kafka-topics.sh --list --zookeeper 192.168.43.177:2181,192.168.43.177:2182,192.168.43.177:2183
sh kafka-topics.sh --describe --zookeeper 192.168.43.177:2181,192.168.43.177:2182,192.168.43.177:2183 --topic test
生产消息：
sh kafka-console-producer.sh --broker-list 192.168.43.177:9091,192.168.43.177:9092,192.168.43.177:9093 --topic test
消费消息：
sh kafka-console-consumer.sh --bootstrap-server 192.168.43.177:9091,192.168.43.177:9092,192.168.43.177:9093 --from-beginning --topic test
问题解决：
1、在windows中使用docker-compse运行compose-docker.yml遇到问题。Mount denied:\nThe source path "\\\\var\\\\run\\\\docker.sock:/var/run/docker.sock"\nis not a valid Windows path
解决方法：设置环境变量 COMPOSE_CONVERT_WINDOWS_PATHS=1
2、java.io.IOException: Can't resolve address: kafka1:9091
解决方法：修改宿主机或其他客户端主机hosts配置，增加以下配置
3、[2019-12-04 17:37:00,848] WARN [Producer clientId=console-producer] Received invalid metadata error in produce request on partition test-0 due to org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.. Going to request metadata update now (org.apache.kafka.clients.producer.internals.Sender)
[2019-12-04 17:37:00,953] ERROR Error when sending message to topic test with key: null, value: 0 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.NotLeaderForPartitionException: This server is not the leader for that topic-partition.
解决方法：修改容器内kafka相关端口，kafka1示例：
ports:
- "9091:9091"
