Kafka 容器无法启动，因为 docker 警告：使用主机网络模式时会丢弃已发布的端口

Question

I have some Kafka docker tests on jenkins working with some different SO images, but if I tried to execute this in local fails,because of warning publish ports are discarded wh host net mode. In my java classes structure I have a KafkaContainer class that extends DockerContainer class with this method:

private static String[] getKafkaConfigs(){
   return new String[]{"--network=host"};
 }

After that I run that Kafka instance with ZookeperContainer, this ZookeperContainer as well, it have got the same method config:

return new String[]{"--network=host"};

The ports are the Kafka (9092) and zookeper(2181) commons ports. In my port 8080, the localhost server running. Any idea, how can I fix it to execute this in a localhost environment.

Thank you

Changing to PODMAN solved the problem. I've read some articles like https://computingforgeeks.com/using-podman-and-libpod-to-run-docker-containers/ and others. It's an excellent alternative and complete CLI compatibility with Docker. BTW, if anyone has a better solution with docker native, please don't hesitate to post it, thank you.
