在docker上启动kafka,是因为最近我们开发的程序需要部署到k8s，在k8s上连接kafka，连接失败，因此我先搭建个环境，以供后续还原问题，解决问题。

一、docker上启动kafka
总结

一、docker上启动kafka

1.下载zookeeper镜像

docker pull wurstmeister/zookeeper

2.下载kafka镜像

docker pull wurstmeister/kafka

3.启动zookeeper

docker run -d --name zookeeper -p 2181:2181  -t wurstmeister/zookeeper

4.启动kafka

docker run -d --name kafka --publish 9092:9092 --link zookeeper:zookeeper -e KAFKA_BROKER_ID=1  -e HOST_IP=192.168.65.7  -e KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.65.7:9092  -e KAFKA_ADVERTISED_HOST_NAME=192.168.65.7 -e KAFKA_ADVERTISED_PORT=9082  --restart=always  -t  wurstmeister/kafka

部分参数含义：

KAFKA_BROKER_ID=1 kafka在集群中的唯一标识
KAFKA_ZOOKEEPER_CONNECT=zookeeper:12181 监听zookeeper的地址 
KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.65.7:19092 kafka服务器的地址

5.进入kafka容器

1.先查看kafka镜像ID:
docker ps -a
在这里插入图片描述
2.进入容器
docker exec -it ${CONTAINER ID} /bin/bash
3.进入kafka的bin目录下
cd /opt/kafka_2.18/bin
4.创建topic
./kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 1 --topic mykafka
5.运行生产者
./kafka-console-producer.sh --broker-list localhost:9092 --topic mykafka
在这里插入图片描述
6.消费topic
./kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --from-beginning --topic mykafka

6.问题记录

1.当第一次启动kafka时报以下错误，连接超时的错，我报这错是因为我启动命令错了：
 ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

报错的启动命令：
docker run -d --name kafka --publish 9092:9092 --link zookeeper --env KAFKA_ZOOKEEPER_CONNECT=192.168.65.7:2181 --env KAFKA_ADVERTISED_HOST_NAME=192.168.65.7 --env KAFKA_ADVERTISED_PORT=9092 wurstmeister/kafka
