        restart: always

其中192.168.26.129需要替换为真实的ip
启动命令：sudo docker-compose up -d

部分kafka命令：

#创建frist主题
kafka-topics.sh --bootstrap-server 192.168.26.129:9092 --create --partitions 1 --replication-factor 3 --topic first
#向first主题中发送消息
kafka-console-producer.sh --bootstrap-server 192.168.26.129:9092 --topic first
#消费frist主题中的消息
kafka-console-consumer.sh --bootstrap-server 192.168.26.129:9092 --topic first
#消费frist主题中的消息（包括历史消息）
kafka-console-consumer.sh --bootstrap-server 192.168.26.129:9092 --from-beginning --topic first
