我正在使用minikube在kubernetes部署kafka/zookeeper。下面是我的yaml文件：

我已经使用minikube和below命令在本地机器kubernetes中成功地创建了部署/服务。

kubectl create -f kafka.yml

我在Kafka豆荚里导航过，我可以用下面的命令创建一个主题，

./bin/kafka-topics.sh --create --zookeeper 192.168.99.100:30181 --replication-factor 1 --partitions 1 --topic test-topic

但是，当我尝试向主题（testtopic）发送消息时，系统抛出以下错误。

笔记
当我运行netstat-tunap时，端口30092和30181都显示已建立。

我不知道我错过了什么。请帮我往前走。
谢谢你的帮助。
