查看进程
netstat -anltp|grep 9092

查看日志
docker logs --tail="500" kafka
docker logs -f kafka

进入容器
docker exec -it kafka /bin/bash

配置key规则：在前面加KAFKA_前缀 全部大写 “.”用“_”代替

如：
增加 Kafka 堆的内存大小 KAFKA_HEAP_OPTS=-Xmx4G -Xms4G
KAFKA_LOG_DIRS=/kafka/logs 时 volumes:- "./kafka3/logs:/kafka/logs"

kafka-manager的environment可设置APPLICATION_SECRET: "xxx"
KAFKA_LISTENERS的值 为内网地址

没配置delete.topic.enable=true，只是软删除

如果将topic软删除，java客户端会报：

WARN Error while fetching metadata with correlation id 0 : {test=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

报 org.apache.kafka.clients.NetworkClient   : [Producer clientId=producer-3] 1 partitions have leader brokers without a matching listener, including [log-0]

一般是zookeeper的ip:port配置导致kafka报错问题，配置好后需清理zookeeper数据才会正常。

复制配置
docker cp kafka1:/opt/kafka/config/ /opt/kafka/kafka1_config_bak/

 kafka-manager需在界面手动添加集群配置才能显示。

测试kafka

进入容器
docker exec -it kafka1 /bin/bash

创建topic
/opt/kafka/bin/kafka-topics.sh --create --bootstrap-server 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013 --topic myTestTopic --partitions 3 --replication-factor 3
注：replication-factor个数不能超过broker的个数

查看当前topic列表
/opt/kafka/bin/kafka-topics.sh --list --bootstrap-server 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013

运行一个消息生产者，指定topic为刚刚创建的myTestTopic
/opt/kafka/bin/kafka-console-producer.sh --broker-list 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013 --topic myTestTopic
输入任意字符 然后ctrl+c退出

查看指定topic明细
/opt/kafka/bin/kafka-topics.sh --describe --bootstrap-server 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013 --topic myTestTopic

消费消息
/opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013 --topic myTestTopic --from-beginning
ctrl+c退出

删除topic
/opt/kafka/bin/kafka-topics.sh --delete --bootstrap-server 192.168.0.101:9011,192.168.0.101:9012,192.168.0.101:9013 --topic myTestTopic
如果不能删除，docker启动时配置KAFKA_DELETE_TOPIC_ENABLE: "true"
