我正在使用MINIKUBE在Kubernetes中部署Kafka / Zookeeper。以下是我的YAML文件：

我已使用MINIKUBE通过以下命令在本地计算机Kubernetes中成功创建了Deployment / Services。

kubectl create -f kafka.yml

我已经在Kafka窗格中导航，并且可以使用以下命令创建主题，

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

但是，当我尝试向该主题（test-topic）发送消息时，系统抛出以下错误。

注意

当我运行 netstat -tunap 时，端口30092和30181均显示为已建立。

我不知道我在这里想念的是什么。请帮助我前进。

感谢并感谢您的帮助。

感谢@SoheilPourbafrani和@ cricket_007的帮助！我已经找到了我上面提出的问题的解决方法。

一旦我在PowerShell窗口中运行以下命令，Kafka即可正确启动，并能够通过Node Application和Kafka Tool与之通信。

minikube ssh
sudo ip link set docker0 promisc on 

参考：Newer versions of Minikube don't allow Pods to use their own Services
