Using bare metal server behind k3s

Hi,
I’m using k3s on a home server for a few server. These works as expected. I’ve a Raspberry Pi as bare metal server. I can’t figure out/perform to manage Pi’s web service over k3s.
How can I serve Pi’s web service via k3s?
Thanks for advance.

I’m using following yaml:

http:
  routers:
    pihole-rtr:
      entryPoints:
        - https
      rule: Host(`pihole.domain.ltd`)
      service: pihole-svc
      middlewares:
        - pihole-add-admin
      tls:
        certresolver: letsencrypt-prod
  middlewares:
    pihole-add-admin:
      addPrefix:
        prefix: /admin
apiVersion: networking.k8s.io/v1
kind: Ingress
  services
    pihole-svc
      loadBalancer
        servers
          - url 'http://192.168.1.32:80'
      passHostHeader true

This error occurs;

error: unable to recognize “app-pihole.yaml”: no matches for kind “Ingress services pihole-svc loadBalancer servers - url ‘http://192.168.1.32:80’ passHostHeader true” in version “networking.k8s.io/v1
