Kubernetes本地部署Ingress Nginx所有路由返回404问题求助

我遇到了和Kubernetes Ingress Nginx Controller is Not Found类似的问题。

我正在本地部署项目，访问后端地址http://posts.com/posts和前端地址http://posts.com均返回404。只有使用地址http://posts.com:32685/posts才能正常访问后端，同端口访问http://posts.com:32685前端仍然失效。我查阅了大量相关资料仍未解决，卡壳很久了 :(

ingress-srv.yaml配置如下： #

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-srv
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/use-regex: "true"

                port:
