Question

我在kubernetes 单节点 上运行kafka和zookeeper时遇到问题，我在我的笔记本电脑上进行了测试，并且可以正常工作，但我在私有计算机上运行服务器在kafka pod中显示错误，并且我不知道私有服务器上的网络设置

我使用kompose将docker-compose文件转换为k8s yaml文件

zoo1：名称解析暂时失败

如何解决该错误？

谢谢

您必须为kafla和zookeeper创建无头服务

我建议使用合掌舵图在kubernetes中使用kafka，您可以找到他们如何创建无头服务。

什么是日志？到底是怎么回事？

希望有帮助！

错误Kafka无法在Kubernetes上连接Zookeeper（单节点）
