Error from server (InternalError): error when creating “ingress.yaml“: Internal error occurred: fail

在创建ingress策略yaml文件
执行kubectl apply -f ingress.yaml命令时报错：
Error from server (InternalError): error when creating “ingress.yaml”: Internal error occurred: failed calling webhook “validate.nginx.ingress.kubernetes.io”: failed to call webhook: Post “https://ingress-nginx-controller- admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s”: dial tcp 10.101.148.253:443: connect: con nection refused

【解决方案】
查看kubectl apply -f ingress.yaml

kubectl get validatingwebhookconfigurations

删除ingress-nginx-admission

kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission

再执行命令，成功

kubectl apply -f ingress.yaml
