I am working on deploying Kafka/Zookeeper in Kubernetes using MINIKUBE. below is my YAML file:

I have successfully created the Deployment/Services in local machine Kubernetes using MINIKUBE using below command.

kubectl create -f kafka.yml

I have navigated inside Kafka pods and I am able to create a topic using below command,

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

But, When I try to send a message to the topic (test-topic), the system throws the below error.

Note

when I run netstat -tunap , both port 30092 and 30181 is showing established.

I don't know what I am missing here. Please help me to move forward.

Thanks and Appreciate your help.
