我是 kubernetes 的新手，我正在尝试将 kafka 与 debezium 和 mysql 集成。我在 minikube 上成功部署了 kafka 和 mysql，一旦我在 minikube 上部署了 debezium yml，它就被挂起并且根本没有响应，然后我重新启动 minikube，在运行所有 pod minikube 后再次被挂起。下面是我的代码：

当我部署 debezium 时，问题就开始了，minikube 响应就像
$ kubectl get pods
Unable to connect to the server: net/http: TLS handshake timeout
操作系统：Centos
minikube 版本：v0.30.0
