在本地minikube设置中使用K8和入口。从www.example.com api版本中的yaml文件创建入口networking.k8s.io/v1失败。请参见以下输出。正在执行

> kubectl apply -f ingress.yaml

返回

Error from server (InternalError): error when creating "ingress.yaml": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": an error on the server ("") has prevented the request from succeeding
