让nginx-ingress在Azure中使用UDP

Question

The Service "nginx-ingress-controller" is invalid: spec.ports: Invalid value:

正如我所说的，当使用tcp时，这工作非常好，但当我切换到UDP时，错误弹出，是不是我缺少了一个UDP步骤？

EDIT>add helm命令（如microsoft所述）以使用此命令

helm install nginx-ingress stable/nginx-ingress --namespace ingress-nginx --set controller.replicaCount=2 --set controller.nodeSelector."beta\.kubernetes\.io/os"=linux --set defaultBackend.nodeSelector."beta\.kubernetes\.io/os"=linux --set controller.service.httpPort.enable=false --set controller.service.httpsPort.enable=false

基于以下错误：

The Service "nginx-ingress-controller" is invalid: spec.ports: Invalid value:
 []core.ServicePort
{core.ServicePort{Name:"proxied-udp-30001", Protocol:"UDP", Port:30001, TargetPort:intstr.IntOrString {Type:0, IntVal:30001, StrVal:""}, NodePort:0}, 

core.ServicePort{Name:"proxied-udp-30002", Protocol:"UDP", 
Port:30002, TargetPort:intstr.IntOrString{Type:0, IntVal:30002, StrVal:""}, 
NodePort:0}, 

core.ServicePort{Name:"http", Protocol:"TCP", Port:80, 
TargetPort:intstr.IntOrString{Type:1, IntVal:0, StrVal:"http"}, NodePort:32724},

core.ServicePort{Name:"https", Protocol:"TCP", Port:443, 
TargetPort:intstr.IntOrString{Type:1, IntVal:0, StrVal:"https"}, 
NodePort:30127}}:

错误告诉您正在尝试使用端口类型中的混合匹配更新服务。

无法使用混合协议创建外部负载均衡器
